Aims: To develop and evaluate for the National Prescribing Service (NPS) a web-based interactive prescribing curriculum for Australian senior medical students based on the World Health Organization's Guide to Good Prescribing. Methods: Teachers of prescribing from all Australian medical schools in 2000 wrote 12 case-based modules which were converted to on-line format. Objective evidence was provided for selecting first-line medicines from available alternatives by comparing efficacy, safety, convenience and cost. The curriculum was made available to final year students in 2001 and was evaluated by measuring use from web statistics and by semistructured interviews with 15 teachers (2003) and on-line surveys of 363 students over 2003 and 2004. Results: By 2004 the curriculum was used by nine of 11 possible medical schools. Uptake increased each year from 2001 and all 12 modules were accessed consistently. Student access was significantly (P < 0.001) greater when prescribing was an assessable part of their course. Teachers' evaluations were uniformly supportive and the curriculum is seen as a valuable resource. Student responses came from a small proportion of those with password access but were also supportive. Over half of student respondents had created their own evidence-based formulary. Conclusions: A collaborative venture initiated by the NPS with Australian medical schools has been successfully implemented in most courses. Teachers find the resource of high quality. Student respondents find the curriculum valuable in developing their own prescribing skills. It is best delivered by self-directed study followed by tutorial discussion of prescribing decisions. © 2006 Blackwell Publishing Ltd.

To ascertain the pattern of antimicrobial use and to assess its appropriateness a 4-month prospective study was conducted from January through April 1998 in paediatric wards of five selected medical college hospitals in Bangladesh. The hospitals were selected by simple random technique. Every patient in the paediatric wards of the selected hospitals who was being treated with antimicrobials during the data collection period was considered for the study. The treatment charts of 2171 admitted paediatric patients were reviewed. Pneumonia and diarrhoea were the two most common infectious diseases among them. The most commonly used antimicrobials were ampicillin, gentamicin, amoxicillin, cloxacillin and ceftriaxone. The majority of the admitted paediatric patients (56.1%) included in this study received two or more antimicrobials in combination for their treatment. The percentages of appropriate antimicrobial treatment of pneumonia, and diarrhoea were 57.1% and 67.8% respectively across the hospitals. The evident of high percentages of inappropriate antimicrobial treatment for the most common infectious diseases suggested the need for intervention to improve antimicrobial use in hospitals.

While poor drug compliance is a significant impediment to the effective treatment of hypertension, knowledge of what patients wish to know about their medications in order to improve compliance is very limited. To develop a preliminary understanding of patients' medication requirements and expectations, a simple 30-item questionnaire was developed and administered to 66 patients who were either taking antihypertensive drugs, or about to commence antihypertensive drug treatment. Ninety percent of patients wanted to know about all possible side effects of medications as well as the most likely side effects. Ninety-six percent wanted to know if their drug treatment would keep them well. In addition, most patients wanted to avoid multiple medications, were concerned about the prospect of life-long treatment, and were worried about potential drug interactions. Effects of the drugs on their lifestyles as well as any lifestyle changes required to augment drug therapy were other issues of concern. The elderly were less interested in many of these issues. A strong desire for further knowledge about their disease was noted in most subjects (82%). If compliance with medication therapy is to be improved, a better understanding of patients' concerns and fears about medications is required, particularly in a relatively asymptomatic disease like hypertension.

Periodic evaluation over the past 20 years of the ability of clinical staff to accurately measure blood pressure, as well as the functional state of sphygmomanometers, has frequently demonstrated significant deficiencies. The data presented here are the results of a recent audit in the Newcastle area. Medical (48) and nursing (217) staff in five general hospitals (3 public, 2 private), were questioned on sphygmomanometer use, observed taking a blood pressure reading and asked to record blood pressures from a videotape. In addition, all hospital sphygmomanometers were checked to see if they were in working order. Of 463 sphygmomanometers evaluated, 58% were in perfect working order. There was a marked variation in the state of equipment between institutions (40 to 94%). Staff knowledge and technical ability in sphygmomanometer use was similar in doctors and nurses, with 69% of doctors and 71% of nurses knowing that phase V Korotkoff sounds best approximated adult diastolic blood pressure. Knowledge of appropriate cuff size and ability to use a sphygmomanometer was also similar between the two groups. However, doctors performed better in measuring systolic and diastolic blood pressures from a videotape (9.3 ± 1.7 correct compared with 7.8 ± 1.9 for nurses; P < 0.01). It was concluded that, with the exception of one hospital, the state of repair of sphygmomanometers was poor. Staff knowledge of sphygmomanometer usage and their ability to record blood pressure was satisfactory. However, not all practising health professionals are competent in using a sphygmomanometer.

Summary. Irrational prescribing is a habit which is difficult to cure. However, prevention is possible and for this reason the WHO Action Programme on Essential Drugs aims to improve the teaching of pharmacotherapy to medical students. The impact of a short problem-based training course in pharmacotherapy, using a WHO manual on the principles of rational prescribing, was measured in an international multi-centre randomised controlled study of 219 undergraduate medical students in Groningen (Netherlands), Kathmandu (Nepal), Lagos (Nigeria), Newcastle (Australia), New Delhi (India), San Francisco (USA), and Yogyakarta (Japan). The manual and the course presented the students, who were about to enter the clinical phase of their studies, with a normative model for pharmacotherapeutic reasoning in which they were taught to generate a "standard" pharmacotherapeutic approach to common disorders, resulting in a set of first-choice drugs called P(ersonal)-drugs. The students were then taught how to apply this set of P-drugs to specific patient problems on the symptomatic treatment of pain, using a six-step problem-solving routine. The impact of the course was measured by tests before training, immediately after, and six months later. After the course, students from the study group performed significantly better than controls in all patient problems presented (p < 0·05). The students not only remembered how to solve old problems, but they could also apply their skills to new problems. Both retention and transfer effect were maintained at least six months after the training session in all seven medical schools. In view of the impossibiity of teaching students all basic knowledge on the thousands of drugs available, this approach seems to be an efficient way of teaching rational prescribing. However, the method should be accompanied by a change in teaching methods away from the habit of transferring knowledge about the drugs towards problem-based teaching of therapeutic reasoning. © 1995.

Objective: To establish equivalent doses of four non-steroidal anti-inflammatory drugs (NSAID) in normotensive and hypertensive rats using inhibition of the fall in blood pressure produced by the injection of arachidonic acid as the measure of equivalence. Design: An experimental study using two rat models of hypertension and their normotensive controls. Methods: Two rat models of hypertension (spontaneously hypertensive rats and two-kidney, one clip rats) and their normotensive controls were studied. The change in blood pressure after intravenous injection of arachidonic acid was measured in anaesthetized rats. Blood pressure was measured from a carotid artery cannula, attached to a pen-recorder. Dose-response curves for the effect of arachidonic acid were established in each type of rat, then the effects of different doses of four NSAID (indomethacin, piroxicam, naproxen and sulindac) on these responses were measured. Results: Arachidonic acid produced a dose-dependent fall in blood pressure in all rats. However, both types of hypertensive rats sustained a larger fall in blood pressure for a given dose of arachidonic acid than did the normotensive controls. Doses of NSAID were found that inhibited this response in Wistar rats. However, the doses of NSAID that were equivalent in normotensive rats were not equivalent in either type of hypertensive rat; indomethacin had a greater inhibitory effect. As far as could be established, this was not due to differences in the metabolism of the NSAID between normotensive and hypertensive rats. Conclusions: The arachidonic acid response can be used as a method of establishing equivalent doses of NSAID in normotensive and hypertensive rats. Hypertensive rats appear to be more sensitive to the effects of arachidonic acid than normotensive rats, independent of the model of hypertension. Doses of NSAID that are equivalent in normotensive rats are not equivalent in hypertensive rats. Indomethacin is more effective in attenuating the effect of arachidonic acid, possibly due to actions other than inhibition of cyclo-oxygenase. © Current Science Ltd.

1. Pretreatment with intravenous WEB-2086 (0.5 mg/ kg; an antagonist of the actions of platelet activating factor; PAF) with or without indomethacin (2 mg/ kg) failed to prevent or modify the fall in blood pressure following unclipping of the renal artery of anaesthetized two-kidney, one-clip hypertensive rats. 2. The same medications given to two other groups of rats 60 min after unclipping when the blood pressure had fallen to stable levels failed to reverse the fall. 3. Despite evidence that both prostanoids and PAF can be detected in increased amounts in renal venous blood after unclipping, they do not appear to mediate the reduction in blood pressure in this model of reversible hypertension.

We compared clinical supervisors¿ ratings of intern competence in Newcastle University graduates (whose medical school emphasizes community relevance and interpersonal skills) and in medical graduates of the Universities of Sydney and New South Wales, which have more traditional curricula. A 12-item anchored supervisor rating scale was used to assess the professional competence of 428 interns on five occasions throughout the intern year. Data analysis was performed using two factors of clinical competence and personal characteristics, as well as an average annual total score. linear regression analysis was employed to estimate the adjusted effects of age, sex, and graduating university on the three scores. All three scores were higher for interns who graduated at younger than 25 years, irrespective of university of graduation or sex. Women scored higher on average than men, and Newcastle graduates were rated significantly better on average than Sydney University graduates for the personal characteristics scores. At the beginning of the intern year, Newcastle graduates had higher total scores than graduates from the two other medical schools. By the end of the intern year, there was no difference in total scores for the three universities. The results of this study suggest that age, sex, and curriculum background are factors influencing aspects of performance at entry to the internship year and also the professional development of interns throughout that year. © 1994, Taylor & Francis Group, LLC.

1. Standard renal clearance techniques were used to compare the acute effects of gentamicin, neomycin and tobramycin on renal calcium and magnesium handling in Sprague-Dawley and Fischer 344 rats. 2. Significant hypercalciuric and hypermagnesiuric responses to all three drugs (P < 0.01) were apparent within 30 min of the onset of drug infusion. 3. The magnitude of the acute hypercalciuric and hypermagnesiuric response to the three aminoglycosides was comparable. This contrasts with their nephrotoxic action where neomycin > > gentamicin > tobramycin. The magnitude of the acute physiological responses to these drugs do not therefore reflect their nephrotoxic potential. 4. Sprague-Dawley rats were at least as responsive as Fischer rats in their acute renal responses to gentamicin. If Fischer rats are more sensitive to aminoglycoside nephrotoxicity than Sprague-Dawley rats, this is not reflected in their acute responses to gentamicin. Copyright © 1994, Wiley Blackwell.

In an open study that was conducted in general practice, 22 patients with previously-untreated mild hypertension received an average daily dose of 11.7 mg of pindolol over a 50-week study period. The total cholesterol, high-density lipoprotein fraction and plasma triglyceride levels showed no significant change from baseline values at the conclusion of this period. A separate group of 18 patients were treated with 10 mg of pindolol a day for 12 weeks, to which regimen was added 5 mg of clopamide for the succeeding 38 weeks. A small rise in total plasma cholesterol levels in this group of patients at both 12 and 50 weeks did not achieve statistical significance, and no change was observed in either the high-density lipoprotein fraction or the plasma triglyceride levels. These results which were obtained in general practice and over a prolonged period of time accord with the general view that the treatment of hypertension with pindolol, a ß-receptor blocking drug with partial agonist activity, is not associated with either the increase in total plasma cholesterol levels or the falls in the high-density lipoprotein fraction that have been reported with other ß-blocking compounds.

This article summarizes the theoretical basis and practical applications of the fluid management of shock in critically-ill patients. It also draws attention to the differences in the aetiology and management of fluid disturbances in adult and paediatric practice. Some evidence suggests that colloidal solutions alone may be superior to crystalloid solutions alone in the resuscitation of patients with shock, but in most situations a combination of both types of fluid is more logical.

1. Segments of the tail artery of the rat were cannulated at both ends and mounted in an organ bath filled with Krebs solution. 2. Using an extracorporeal circuit, blood was pumped at a constant 2 ml/min from the carotid artery of anaesthetized rats to perfuse the segment of tail artery, and returned to the donor rat via the jugular vein. 3. Peri-arterial electrical stimulation of the ex vivo blood perfused tail artery at 5 Hz produced vasoconstriction and an increase in perfusion pressure. 4. The intravenous administration of frusemide 5 mg/kg to the donor rat resulted in an inhibition of the vasoconstrictor responses of the perfused tail artery segment. Diuresis-induced losses of volume and frusemide were prevented by a urinary bladder-venous shunt. 5. Removal of the endothelium from the tail artery segment, by perfusion with dry gas for 4 min, prevented the vasoconstrictor-inhibitory effect of frusemide administration. Removal of the endothelium was confirmed histologically and by the absence of a vasodilator response to acetylcholine. 6. On the basis of these and previous results it is concluded that parenteral frusemide administration releases an unidentified but non-prostanoid hormone from the kidney which produces an endothelium-dependent inhibition of sympathetic vascoconstriction.

Dissolution studies and a 24 patient randomized double-blind crossover bioavailability study were performed using two commercially-sized batches of an ibuprofen 200 mg tablet formulation (sugar-coated). The batches were equivalent with respect to the USP dissolution test, but differed, particularly from tablet-to-tablet, when a paddle at 50 rpm was substituted, one batch consistently giving a high dissolution and the other consistently giving a low dissolution. The bioavailability study showed the batches to be bioequivalent, thus prompting an investigation as to why the substitution of a paddle at 50 rpm gave no correlation with bioavailability and should therefore be unsuitable as a standard dissolution test. It was found that soaking tablets in acid prior to using the paddle at 50 rpm (thus simulating more closely the in vivo pH sequence) increased the dissolution rate. The increase is such that the maximum dissolution rate, which also approximates that given by the USP method, is achievable within five minutes, even when the presoak medium is an unbuffered solution of hydrochloric acid at pH 4. A standard presoak procedure was then developed consisting of soaking each tablet for five minutes in 5 ml of USP gastric fluid without pepsin at room temperature and with no agitation. A comprehensive application of this procedure to both batches consistently produced results equivalent to those obtained by the USP method. In particular, there was very little tablet to tablet variation. Studies with formulations of varying bioavailability will be necessary before it can be determined whether this new acid presoak procedure will provide a more meaningful dissolution test compared with the current USP method. © 1988 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.

The mesentery of anaesthetized rats was perfused in situ at a constant rate, via the cannulated superior mesenteric artery, with blood drawn from a cannulated carotid artery. Increases in perfusion pressure were produced by peri-arterial electrical stimulation of the mesenteric sympathetic nerves at 3, 6 and 10 Hz before and after the intravenous administration of frusemide 5 mg/kg. Loss of solutes and volume as a result of frusemide-induced diuresis was prevented by a urinary bladder-venous shunt. In control animals the vasoconstrictor responses to mesenteric nerve stimulation were significantly reduced after frusemide administration. However, in animals pretreated 4 weeks previously with bromethylamine (BEA) 200 mg/kg i.p., frusemide had no effect on vasoconstrictor responses. Chemical papillectomy with BEA has been shown by others to prevent the antihypertensive effects attributed to the non-prostanoid lipids produced by the interstitial cells of the renal medulla. Our data suggest that the vasoconstrictor-inhibiting effect of frusemide may be mediated by the release of renomedullary lipids. © Gower Academic Journals Ltd.

1. Mesenteric perfusion pressure was measured in the in situ blood-perfused mesentery of anaesthetized rats. Increases in perfusion pressure were produced by mesenteric periarterial electrical stimulation at 3, 6 and 10 Hz before and after the administration of frusemide 5 mg/kg intravenously (i.v.) or vehicle. Loss of volume due to diuresis was prevented by replacement with intravenous saline. 2. Frusemide did not cause any changes in blood pressure or baseline perfusion pressure. Responses to electrical stimulation were inhibited by frusemide (P < 0.05) but unchanged by vehicle administration. 3. Acute bilateral nephrectomy or treatment with indomethacin (2 mg/kg i.v.) prevented the inhibitory effect of frusemide on responses to sympathetic nerve stimulation. 4. Responses to sympathetic nerve stimulation were potentiated by an infusion of angiotensin II (12 ng/min) into the mesenteric artery. This infusion did not alter either blood pressure or baseline perfusion pressure. Administration of frusemide 5 mg/kg i.v. attenuated the potentiating effect of angiotensin II on vasoconstrictor responses to electrical nerve stimulation. 5. Frusemide may lead to the release of a prostanoid or prostanoid precursor which inhibits vascular constrictor responses. Copyright © 1986, Wiley Blackwell. All rights reserved

Three groups of rats were fed a low-sodium diet. Group 1 drank water and was treated with cyclosporine, 100 mg kg -1 > 48 h-1 p.o. for 3 weeks (low-salt-treated group). Group 2 drank 0.15 M saline and was also treated with cyclosporine (high-salt-treated group). Group 3 drank water and was treated with the vehicle (low-salt-vehicle group). Measurements were made during a control period and weekly during the 3-week treatment period and a 3-week recovery period. Both cyclosporine-treated groups lost weight during treatment but the rises in serum creatinine and blood urea and decrease in creatinine clearance were greater in the low-salt group. The vehicle group gained weight and had no change in the other parameters over the three weeks. There was an increase in urine volume and sodium excretion in the high-salt group associated with cyclosporine treatment. Although the low-salt groups had a higher plasma renin concentration than the high-salt group there were no changes produced by cyclosporine treatment. Histopathological examination showed mild tubular lesions with vacuolar degeneration of proximal tubular cells. This was more prevalent in the low-salt-cyclosporine¿treated group. The plasma concentrations of cyclosporine were not different after one-week treatment but were slightly greater after 2-week and 3-week treatment in the low-salt group. We have suggested that the greater impairment of renal function in the low-salt group produced by cyclosporine may be contributed to by an involvement of tubuloglomerular feedback. © 1984 by The Williams and Wilkins Co.

Plasma and interstitial fluid volumes have been measured simultaneously in men with uncomplicated and untreated essential hypertension. Plasma volume (Evans blue) was reduced in essential hypertension and correlated inversely with blood pressure. Interstitial fluid volume, derived from bromine space and plasma volume, was also reduced in essential hypertension and correlated inversely with blood pressure. The mean reduction in both plasma and interstitial fluid volumes was 6-7%. There is no evidence for volume expansion in essential hypertension and the relationship between plasma and interstitial fluid volumes is preserved. The contraction of plasma and interstitial fluid volumes is more likely to reflect a natriuresis and diuresis secondary to the raised renal perfusion pressure, and sodium retention is unlikely to be a primary event in essential hypertension.

The 24 h urinary excretion of adrenaline, noradrenaline, metadrenaline, normetadrenaline and vanillylmandelic acid, plasma renin activity and plasma and urinary debrisoquine were measured before and during chronic treatment with oral debrisoquine in 14 in-patients with essential hypertension. There was a significant fall (mean ±SD) in the 24 h urinary excretion of vanillylmandelic acid (15.3±2.8 to 6.7±1.9 µmol) noradrenaline (199.0±105.8 to 125.2±43.3 nmol) and plasma renin activity (0.71±0.47 to 0.40±0.20 pmol Angio I ml -1 h -1 ) while the urinary normetadrenaline/noradrenaline ratio increased (10.4±6.1 to 17.1±5.1). No significant change was seen in the output of adrenaline or of O-methylated metabolites. Debrisoquine produces extensive noncompetitive inhibition of platelet monoamine oxidase in vivo at low therapeutic plasma concentrations. These changes support the view that treatment with debrisoquine produces intraneuronal inhibition of monoamine oxidase and post-ganglionic blockage. There was a significant correlation between the change in standing diastolic blood pressure and the daily dose (r s =-0.52), pre-dose plasma concentration (r s =-0.85) and mean daily urinary recovery (r s =-0.80), of debrisoquine. The full extent of the biochemical changes were seen at low dose and low plasma concentration and were not directly correlated with the fall in standing or supine blood pressure. © 1979 Springer-Verlag.

Relationships between plasma concentrations of acebutolol (Ac) and its N-acetyl metabolite (Am) and pharmacological effects were studied in patients with essential hypertension. In an acute study (N=7) 400 mg oral acebutolol produced similar peak plasma levels of Ac and Am but Am had a longer half life. Group mean pulse and blood pressure fell significantly, although the size of individual blood pressure fall varied five-fold. There was no significant change in plasma renin activity. Correlations were found between drug concentration and ß-blockade, assessed as % reduction in exercise tachycardia, and between both of these and the fall in post exercise systolic blood pressure. Similar comparisons were made in a chronic optimum dose study (N=11) both pre-dose and three hours post-dose. Am concentration was consistently higher than Ac at both times. Blood pressure was lowered equally pre-and post-dose when compared to placebo and plasma renin activity (PRA) was reduced on active treatment. Correlations were again shown between drug concentrations and ß-blockade but none were found with changes in blood pressure or PRA. Between subject differences in blood pressure response could not be fully explained in terms of the other measurements but it is unlikely that pharmacokinetic differences are the major source of this variability. © 1978 Springer-Verlag.

The relation between dose, systemic availability, and response to oral debrisoquine was studied in 13 hypertensive patients receiving no other treatment. In 11 who received the same daily dose (40 mg) the fall in mean standing systolic blood pressure varied between 0.3 and 44.4 mm Hg. There was a ninefold difference in the daily urinary excretion and pre-dose plasma concentration of unchanged drug but an inverse correlation between daily urinary excretion of debrisoquine and its 4-hydroxy metabolite (r = ¿0.86), suggesting that a low recovery of debrisoquine occurs because of extensive metabolism. There was a significant correlation between the fall in standing systolic blood pressure and the mean daily urinary excretion (r = +0.82) and pre-dose plasma concentration (r = +0.82) of unchanged debrisoquine. In contrast, there was a significant inverse correlation between the urinary recovery of the metabolite and the fall in blood pressure (r =¿0.82). The availability of debrisoquine is the major determinant of response to this drug. In the absence of side effects a poor response may be an indication to increase the daily dose rather than add another hypotensive agent. © 1977, British Medical Journal Publishing Group.

Specific methods have been devised for the simultaneous determination of the guanidino-type antihypertensive agent debrisoquine and its 4-hydroxy metabolite in human urine, involving in situ derivatisation with acetylacetone, extraction of the resulting pyrimidines, and gas chromatography using a flame-ionisation detector or a nitrogen-specific detector. Using the latter, a similar procedure was also developed to measure debrisoquine in human plasma and whole blood following prior extraction at pH 13.5 with chloroform. Concentrations down to 3 ng/ml can be measured accurately using a 1.0-ml sample. The methods were applied to the analysis of samples collected after a single 20-mg oral dose of debrisoquine hemisulphate. © 1977.

The 24 h urinary excretion of adrenaline, noradrenaline, normetadrenaline, metadrenaline and vanilloylmandelic acid has been compared in 17 male normotensive subjects and 25 age matched male hypertensive patients studied under similar in patient conditions. 24 h urinary metadrenaline was significantly lower in the hypertensive patients. With this exception, no significant differences were found between the two groups when the total 24 h excretion of free catecholamines and their metabolites was analysed. Diurnal variation in free catecholamine excretion was found in both normotensive and hypertensive subjects. There was no corresponding variation in metabolite excretion. No correlation could be established between systolic or diastolic blood pressure and the amounts of the catecholamines or their metabolites in the urine of either group. The results are considered in the light of recent work demonstrating high plasma catecholamine concentrations in hypertension. They lend no support to the concept that excessive circulating catecholamines are responsible for the elevated blood pressure in essential hypertension.

The diuretic effects of porcine and human calcitonin in animals and man are associated with renal vasodilatation. The hormone itself may not be directly responsible for these effects, however, and since intravenous calcitonin causes increased gastrointestinal activity and flushing in man, prostaglandins (particularly E2 and F2a) may act as intermediaries. If so, the prostaglandin synthetase inhibitor, indomethacin, might modify this response. © 1975, British Medical Journal Publishing Group. All rights reserved.

Difficulties in measurement have limited work on the kinetics of diuretics. Four recent studies are compared which indicate that differences between pharmacological effects in normal subjects of bumetanide and frusemide on the one hand and metolazone and amiloride on the other are partly explained by their kinetics. The role of kinetic factors in diuretic response in disease remains to be investigated.

Symptoms due to orthostatic and exertional hypotension occurred in 23.4 per cent of 448 hypertensive patients treated with guanethidine, debrisoquine, or bethanidine. Symptoms were significantly more frequent in patients treated with guanethidine than in those treated with bethanidine or debrisoquine. Women rather than men and patients with radiological evidence of cardiomegaly, electrocardiographic evidence of left ventricular hypertrophy, or STIT wave changes, developed these symptoms signifcantly more often than other patients. A raised blood urea wasfound morefrequently in patients with postural hypotensive symptoms. Characteristically guanethidine produced early morning postural hypotensive symptoms, whereas hypotensive symptoms caused by bethanidine and debrisoquine occurred at other times of the day and particularly one to two hours after tablet ingestion. Debrisoquine andguanethidine had a significantly greater negative chronotropic effect than bethanidine. It is suggested that negative chronotropic effects of these drugs may potentiate hypotensive symptoms in patients with cardiovascular, renal, or cerebrovascular disease. It should be possible to minimize symptoms of postural hypotension by attention to predisposing factors and selection of treatment accordingly.

The diuretic activity of bumetanide has been studied in 16 normal subjects and 40 hospitalized patients with fluid retention. The drug produced a rapid diuretic response with a pattern of salt and water excretion resembling that of furosemide (Lasix). At the time of maximal natriuresis, which amounted to 13% to 23% of the filtered load of sodium, urinary calcium and magnesium also increased. Urinary urate was unchanged in the first 2 hours after bumetanide, following which there was a phase of urate retention. Free water clearance during maximal hydration was not significantly altered. Comparative studies in edematous patients showed that 1 mg bumetanide was equivalent to 60 mg furosemide. Oral doses of 15 mg bumetanide evoked effective diuresis without adverse effects in 3 edematous patients with advanced renal disease. Prolonged therapy over 7 to 14 weeks with daily doses of 0.25 to 4 mg bumetanide plus potassium supplements controlled edema in 12 patients; asymptomatic hyperuricemia occurred in most, and decreased carbohydrate tolerance in 1. There was no evidence of significant metabolism of bumetanide in vivo. The drug was distributed in a "central" compartment of approximately 5 L. The over-all elimination rate constant was high and indicated that despite rapid renal drug clearance, a substantial part of injected drug left the "central" compartment by one or more extrarenal routes. © 1974.

Two formulations of [ 14 C]-amiloride were compared in six oedema-free subjects in single-dose (20 mg) studies separated by a two-week interval. Calculation of the elimination rate constant (K e ), half-life (T½) and apparent volume of distribution (V d ) from serum and urinary data showed no significant difference between the two formulations. The V d values (350 to 380 litres) were greater than total body fluid volume suggesting extravascular sequestration of amiloride. Serum and urinary amiloride levels were similar with both formulations. Pharmacokinetic parameters were similar to those of an earlier report based on one formulation. The calculated amiloride concentration in the renal distal tubule (3 µm to 20 µm) was similar to, but higher than, reported in vitro concentrations of amiloride which reduced sodium transport in isolated membranes. 1973 British Pharmacological Society

Porcine calcitonin in intravenous doses of 1, 5, 10 and 20 MRC units produced acute increases in urinary volume and sodium, potassium, chloride and bicarbonate excretion in four normal subjects. Infusion of 10 MRC units over a 30 min period in six normal men produced significant increases in urinary volume and sodium, calcium, magnesium, chloride and urea excretion. Urinary potassium, phosphate and bicarbonate were also increased but the increases were not significantly different from control values. These changes in urinary composition accompanied a significant increase in effective renal plasma flow (para-amino hippurate clearance) and a smaller increase in inulin clearance. It is suggested that porcine calcitonin acts as a renal vasodilator in man and that changes in renal electrolyte excretion occur as a consequence. It is possible that renal vasodilation is effected by an active intermediary released by calcitonin rather than by the hormone itself. Copyright © 1972, Wiley Blackwell. All rights reserved

Triamterene reduces the rate coefficients for sodium movement into the transporting system of the isolated frog skin. The isotopically measured ¿active sodium transport pool¿ is also reduced. Mersalyl reduces the rate coefficient for sodium and the calculated sodium flux from the transporting system to the inner bathing solution. The ¿active sodium transport pool¿ is increased by this diuretic. The action of triamterene closely resembles that of amiloride and both reduce the entry of sodium into the system. In contrast, mersalyl limits the exit of sodium ions from the skin. 1971 British Pharmacological Society

Amiloride reduces short-circuit current and potential difference across the isolated frog skin. Isotopically measured sodium influx and efflux are diminished. Total electrical conductance and partial sodium conductance are diminished, the reduction in total conductance being entirely accounted for by the reduction in partial sodium conductance. The effect of antidiuretic hormone (ADH), cyclic 3'5'-adenosine monophosphate (cyclic AMP) and theophylline can be antagonized by pretreatment with amiloride but the antagonism can be abolished by increasing the concentration of these compounds. Amiloride has no effect on oxygen consumption in concentrations which inhibit sodium transport. However, it prevents the stimulatory effect of ADH on oxygen consumption. The results are consistent with an action of amiloride at the passive outside membrane of the transporting cells of isolated frog skin. 1970 British Pharmacological Society

. Amiloride produces a decrease in size of the active sodium transport pool of isolated frog skin. . Rate coefficients for sodium movement into and out of the transporting cells across the outside membrane are decreased by amiloride. The rate coefficient for sodium extrusion across the inside membrane is not significantly affected. . In the presence and in the absence of amiloride, the relation of sodium transport to outside sodium concentration exhibits similar saturation kinetics but amiloride reduces sodium transport rate at every sodium concentration of the outside solution. . Labelling of skin with 14 C-amiloride from the outside solution is significantly greater than labelling with 14 C-inulin. . The results of these studies suggest that amiloride reacts with sites on the outside membrane of the transporting cells as a result of which the rate of sodium movement across this membrane is diminished. 1970 British Pharmacological Society

Amiloride (MK 870), a new potassium-sparing diuretic belonging to the pyrazine carboxamide class was evaluated in 34 hospitalized patients with fluid retention. The drug increased the excretion of sodium, chloride, and water but decreased potassium excretion. The major natriuretic effects of the drug were complete within 24 hours but in a few patients some potassium-sparing lasted longer. The therapeutic efficacy of amiloride was compared with that of triamterene at ceiling dosages selected from the early portion of the dose-response plateaus of the 2 drugs. The natriuretic and potassium-sparing efficacies of 40 mg. amiloride were significantly greater than those of 200 mg. triamterene. At submaximal dosages, amiloride potentiated the natriuresis and reduced the potassium loss evoked by ethacrynic acid. The potassium-retaining action of amiloride was apparent even in the presence of full doses of spironolactone. © 1969.

Amiloride is a new diuretic drug producing moderate natriuretic effects coupled with prominent potassium retention. Though chemically distinct, this compound has some structural similaritites to triamterene, which it also resembles in its effects in normal human subjects, adrenalectomized rats, and on sodium transport across the isolated frog skin. It has no appreciable effect on the urinary concentrating mechanisms. These actions suggest a primary, direct effect upon the distal renal tubule. A dose-response relationship in man is obtained with little increase in effect above 40 mg. At lower doses the effects are manifested within the first IO hours after administration. Doses above 40 mg. prolong these effects to 24 hours. © 1968.

The effects of vasopressin, theophylline and cyclic AMP on sodium transport across isolated frog skin have been studied using 24 Na for the measurement of sodium fluxes. Both vasopressin and theophylline produced consistent increases in short-circuit current, sodium influx and efflux, with a reduction in partial resistance of the skin. The same results were obtained with cyclic AMP only when it was combined with small (loses of theophylline which were by themselves ineffective. The similarity of effect of these three compounds on sodium transport mechanisms strengthens the hypothesis that the physiological activity of vasopressin may be mediated by cyclic AMP. © 1967 The Physiological Society

Examination of the electrocardiograms of 100 students and 202 school children in Lagos, Nigeria, revealed a high incidence of S-T segment elevation in precordial leads, increasing with age and occurring more commonly in males. Biphasic or inverted T waves were found commonly in precordial leads on the right side, occasionally extending as far as Lead V 4 . This is less common in older subjects and may represent a persistence into young adult life of a juvenile form. These normal appearances deserve wider recognition in order to prevent confusion in interpretation of the electrocardiogram. © 1966.
