The efficacy, tolerability and impact on quality of life of amlodipine and enalapril were compared in a multicentre, double-blind, general practice study in 461 mild and moderate hypertensives over a 50-week active treatment period. Amlodipine (5-10 mg, once daily) and enalapril (10-40 mg, once daily) were found to be similarly effective in lowering blood pressure while not adversely affecting quality-of-life parameters. However, 20% of the enalapril group compared with 11% of the amlodipine group required the addition of hydrochlorothiazide for blood pressure control (P < 0.01). Diastolic blood pressure was normalised or reduced by 10 mmHg in 204 (90%) patients on amlodipine and in 190 (85%) patients on enalapril. Side-effects were, in general, mild or of little clinical significance. The major side-effects recorded were class-typical of ACE inhibitors and calcium antagonists, namely cough (enalapril) and oedema (amlodipine), respectively. Tolerability was very good, with only 17 patients (8 amlodipine, 4%; 9 enalapril, 4%) being withdrawn from the study due to side-effects definitely related to treatment. Amlodipine monotherapy produced a slightly beneficial effect on blood lipid concentration, and both drugs reduced the calculated 10-year risk of coronary heart disease. It was concluded that the calcium antagonist amlodipine compared favourably with the ACE inhibitor enalapril in terms of antihypertensive efficacy, tolerability and impact on quality of life.

A 57-year-old man with a cough and increasing exertional dyspnoea for the past 6 weeks was found on examination to have a loud systolic murmur and cardiomegaly with pulmonary congestion. Echocardiography revealed congenitally corrected transposition of the great arteries (cTGA: atrioventricular and ventriculoarterial discordance): a morphologically right ventricle with a tricuspid valve on the left, a morphologically left ventricle with bicuspid a-v valve on the right, the aorta arising ventrally from the left-sided (morphologically right) ventricle. The tricuspid valve showed an Ebstein-like anomaly with obvious regurgitation. Transoesophageal and contrast echocardiography defined valvar anatomy, attachment of the great arteries and cardiac chambers to the venous and arterial circulations, as well as absence of a left to right shunt. Angiography revealed a coronary anatomy typical for cTGA. The exertional dyspnoea responded to diuretics and low doses of ACE inhibitor. Follow-up monitoring of the valvar regurgitation and appropriate endocarditis prophylaxis were recommended. As the haemodynamics in cTGA is normal, in the absence of additional anomalies, it is a congenital cardiac defect which can, though rarely, present first in adulthood. Life expectancy depends on the nature of any additional defects and the degree of commonly associated tricuspid valve regurgitation. As this case demonstrates, echocardiography can largely define the anomalies.

The pharmacological properties of FK 739, a new angiotensin II-receptor antagonist, were examined. FK 739 inhibited the specific binding of [125I]-angiotensin II to rat aortic smooth muscle cell membrane with an IC50 value of 8.6 nM, but did not displace the specific binding of [125I]-angiotensin II to bovine cerebellum membrane. In isolated helical strips of rabbit aorta, FK 739 shifted the concentration-response curve of angiotensin II-induced contraction in parallel to the right, and the values of the slope and pA2 were 1.06 and 8.45, respectively. In in vivo studies, oral administration of FK 739 at 10 mg/kg significantly inhibited the angiotensin I-induced pressor response in normotensive rats and dogs, and it caused a fall of mean blood pressure in renal hypertensive rats and dogs. In spontaneously hypertensive rats, FK 739 at 32 and 100 mg/kg significantly decreased the mean blood pressure in a dose-dependent manner. Additionally, we studied whether FK 739 would cause side effects such as dry cough, like other ACE inhibitors did. Oral administration of FK 739 (10 and 32 mg/kg) did not affect the capsaicin-induced bronchial edema. On the other hand, captopril (10 mg/kg) significantly enhanced capsaicin-induced bronchial edema. These results indicate that FK 739 is a potent and competitive antagonist for AT1-type receptors, and suggest that FK 739 might be a safe and useful agent for the treatment of hypertension in clinical trials.

Persistent dry cough is one of the most common side-effects during therapy with ACE inhibitors. The frequency of cough ranges widely (from 0.2% to 15%) in different series, being higher in small studies and smaller in retrospective studies with large number of patients. The aim of the present study was to evaluate the true frequency of cough induced by treatment with ACE inhibitors in Greek hypertensives and to determine various possibly correlated parameters, including sex, duration of therapy and kind and dose of ACE inhibitors. All hypertensive patients followed in our Hypertension Clinic and treated with ACE inhibitors participated in the study. A total of 228 patients, 103 males and 125 females, 24-80 years of age, were treated with ACE inhibitors for a period of 1-41 months: 121 with enalapril, 40 with captopril, 39 with lisinopril, 25 with perindopril and 3 with ramipril. During treatment with ACE inhibitors persistent dry cough occurred in 15 patients, 12 women and 3 men, giving a frequency of 6.58%. Eleven patients (4.82%) volunteered the information and three after questioning. The mean age of these 15 patients with cough was significantly higher from that of the group (n = 213) without cough (64.27 +/- 2.5 vs. 57.9 +/- 0.74 years, mean +/- SEM, P = 0.024). The 12 women with cough were significantly older than the 113 without cough (67.77 +/- 2.8 vs. 57.8 +/- 1.04 years, P = 0.032).(ABSTRACT TRUNCATED AT 250 WORDS)

Diseases of the respiratory organs comprise almost 4% of the adverse drug reactions reported to the Spontaneous Adverse Drug Reactions Center, SANZ (169 of the 4415 reports collected between 1981 and 1990). The most frequent reports were coughing caused by ACE inhibitors, attack of bronchial asthma induced by nonsteroidal anti-inflammatory drugs and beta-blocking agents, interstitial pneumopathy caused by amiodarone and sulfonamides, and respiratory depression due to benzodiazepines. The spontaneous reporting system does not allow one to determine the incidence, the reports are only of a signal-generating function. Classical semiology and special diagnostic techniques in assessing adverse drug reactions are discussed. A precise analysis of the case, temporal correlation with reaction and exposure time as well as comparisons with similar cases, together with a critical study of the literature on adverse drug reactions, remain the most important diagnostic procedures.

A one-year open study was focused on the therapeutic effect and tolerance of spirapril in 171 patients with mild to moderate hypertension in 11 centres in the Czech and Slovak Republic. The antihypertensive effectiveness was investigated after four weeks, after 12 weeks and after 52 weeks. Only the results recorded after one year are reported. The study was completed after one year by 139 patients, incl. 120 (86.3%) with a normal diastolic pressure of 90 mmHg or less. The study was not completed by 32 patients (18.8%): because treatment was not effective--9.4%, because of undesirable effects--4.7%, 3.5% were eliminated by the investigators for various reasons (change of domicile, poor collaboration) and 1.2% because the protocol was not respected. According to the analysis "intention to treat" the diastolic pressure was normalized by monotherapy with spirapril in 25.1% of the baseline group; combination of spirapril with bopindolol led to normalization of the pressure in another 38.0% patients and in 7.0% patients normal diastolic pressure was achieved by a combination of spirapril with a hydrochlorothiazide; i.e. a total of 70.1% of the baseline group had a normal diastolic pressure after one year of treatment. In another 9.4% of the baseline group the diastolic pressure declined by 10 mmHg or more but not to normal levels. Thus normalization or effective control of pressure was achieved after one year in 79.6% patients according to the analysis "intention to treat". The combination of spirapril and bopindolol proved very effective. Patients where it was necessary to combine spirapril with bopindolol or hydrochlorothiazide had significantly higher baseline readings of blood pressure. During treatment the authors did not record in any of the groups a change of lipids, potassium, uric acid, the haemogram, liver tests or creatinine. Treatment was well tolerated and undesirable effects were rare (most frequent side effects: cough 3.5%, vertigo also 3.5%). The results of the study indicate that spirapril is an effective and well tolerated ACE inhibitor in the treatment of hypertension and its combination with bopindolol is equally suitable as the combination of spirapril with hydrochlorothiazide.

Mepyramine-theophylline-acetate (MTA), a theophylline derivative combined with an antihistamine, is used to treat patients with asthma. A double-blind, randomized, prospective, parallel-group study was conducted to evaluate the efficacy and safety of MTA in the treatment of asthmatic crisis in children 2 to 6 years of age. Forty patients with mild-to-moderate asthma were admitted to the study. The MTA group received 8 mg/kg per day of MTA by mouth in three divided doses for 7 days. The other group received 50 microL/kg per day of placebo in three divided doses for 7 days. Salbutamol (albuterol) syrup was used as the rescue drug if manifestations of asthma persisted. Both the MTA group and the placebo group had similar demographic characteristics at baseline. Both groups showed improvement of the asthma symptoms (cough, dyspnea, hypoventilation, and wheezing), as evaluated by the investigators at days 3 and 7. Patient diary scores showed earlier improvements in the MTA group than in the placebo group. Both groups showed improvement in peak flow at days 3 and 7 (P = 0.005). The control group used more doses of salbutamol than the MTA group on days 2 through 6 and globally (mean +/- SD, 6.79 +/- 9.11 doses vs 1.29 +/- 2.23 doses). The improvements in the placebo group were thought to be due to salbutamol. Three MTA patients dropped out of the trial, one because the parents felt that the treatment was not effective and two because of gastrointestinal manifestations (epigastric discomfort and vomiting). In the placebo group, two patients dropped out. One patient had epigastric discomfort and the other had to be treated in the emergency department for an exacerbation of the asthma. We conclude that MTA may be a good therapeutic option for the treatment of asthmatic crisis in children 2 to 6 years of age.

Angiotensin-converting enzyme inhibitors (ACE-I) have been proven to be effective in reducing morbidity and mortality in patients with heart failure or post-myocardial infarction left ventricular dysfunction. Despite evidence from several large-scale randomized trials, the use of ACE-I in patients with heart failure remains relatively low. In part, the failure to achieve more widespread use of ACE-I in patients with heart failure may be due to physician's perceptions of the side effects associated with ACE-I, such as angioedema, renal dysfunction, cough, and hypotension. Many of these side effects are thought to be due to ACE-I-induced bradykinin accumulation. It is possible to inhibit the effect of angiotensin II without increasing bradykinin levels using an angiotensin II type I blocking agent such as losartan. How effective losartan is compared with an ACE-I is uncertain, however. Some of the beneficial effects of ACE-I have been attributed to bradykinin accumulation, and therefore ACE-I might have an advantage compared with an angiotensin II type I receptor antagonist such as losartan. On the other hand, angiotensin II may be produced by non-ACE-I-dependent mechanisms, which would suggest that an angiotensin II type I receptor blocking agent would be advantageous. To determine the relative safety and efficacy of an ACE-I, which results in bradykinin accumulation and inhibitors of angiotensin II, versus an angiotensin II type I receptor blocking agent, which does not result in bradykinin accumulation, we have begun the Evaluation of Losartan In The Elderly (ELITE) trial, which will compare the safety and efficacy of captopril and losartan in elderly patients with heart failure.

One hundred and thirty five non-smoking hypertensive patients with ACE inhibitor cough confirmed by lisinopril rechallenge and placebo dechallenge were recruited into a double-blind random parallel-group comparison of losartan 50 mg, lisinopril 20 mg and hydrochlorothiazide 25 mg each given once daily for a maximum of 8 weeks. The aim of the study was to compare the incidence of cough with the angiotensin II antagonist losartan, the ACE inhibitor lisinopril and the hydrochlorothiazide in hypertensive patients with previous ACE inhibitor cough. Cough detected by self-administered questionnaire was the primary end-point, and cough frequency by visual analogue scale a secondary end-point. The incidence of cough with losartan (29%) was lower than that for lisinopril (72%, P < 0.01) and similar to that for hydrochlorothiazide (34%). Cough frequency by visual analogue scale was lower for losartan than lisinopril (P < 0.01) and similar to that for hydrochlorothiazide. The specific selective AT1 angiotensin II receptor antagonist losartan is significantly less likely than lisinopril to cause cough in patients who previously have had ACE inhibitor cough. ACE inhibitor cough is likely to be related to non-specific kininase II inhibition.

C-fibres probably represent the common final pathway in both ACE inhibitors and neoplastic cough. A recent report demonstrated that inhaled sodium cromoglycate is an effective treatment for ACE inhibitors' cough; this effect might be due to the suppression of afferent unmyelinated C-fibres. We tested the hypothesis that inhaled sodium cromoglycate might also be effective in lung cancer patients who presented with irritative neoplastic cough. Twenty non-small-cell lung cancer (NSCLC) patients complaining of cough resistant to conventional treatment were randomised to receive, in a double-blind trial, either inhaled sodium cromoglycate or placebo. Patients recorded cough severity daily, before and during treatment, on a 0 to 4 scale. The efficacy of treatment was tested with the Mann-Whitney U-test for non-parametric measures, comparing the intergroup differences in the measures of summary of symptom scores calculated in each patient before and after treatment. We report that inhaled sodium cromoglycate can reduce cough, also in NSCLC patients and that such reduction, observed in all patients treated, is statistically significant (P < 0.001). Inhaled sodium cromoglycate appears to be a cost-effective and safe treatment for lung cancer-related cough.
