- The purpose of this study was to evaluate the potentiating effect of hydrochlorothiazide (HCTZ) 12.5 or 25 mg once daily when added in a placebo-controlled double-blind randomized study of patients with essential hypertension, whose diastolic blood pressure (DBP) was not adequately controlled (DBP > 90 mmHg) following 6 weeks of single-blind treatment with the angiotensin converting enzyme (ACE) inhibitor enalapril, 20 mg once daily. Forty-eight patients started the first period with enalapril after 4 weeks on placebo. In 13 patients DBP fell to < or = 90 mmHg after enalapril for 6 weeks. In this group supine mean arterial pressure (MAP) was reduced by 13% (P < 0.01). In the patients whose DBP was > 90 mmHg after 6 weeks on enalapril (n = 32) the average supine MAP fell by 9% (P < 0.001). After 3 weeks there was no further drop in blood pressure (BP). Addition of HCTZ to the 32 patients with DBP > 90 mmHg caused a significant further drop in supine BP by 13/7 mmHg with 12.5 mg and by 15/7 mmHg with 25 mg. Seven patients discontinued the study, none due to side effects on enalapril alone. Well-being, assessed with a special questionnaire, was significantly better with enalapril as monotherapy compared with previous treatment, but not different from well-being during the placebo periods. It is concluded that 20 mg enalapril once daily lowered BP effectively and was well tolerated. The maximum BP lowering effect was seen within 3 weeks. Addition of HCTZ caused a significant, and clinically relevant, further drop in BP.(ABSTRACT TRUNCATED AT 250 WORDS)

- We are currently fighting a battle against a stroke epidemic. Implementation of new treatment strategies could save many patients in the future. The control of blood pressure is a major objective; however, choosing specific antihypertensive therapy (e.g. an agent blocking the renin-angiotensin system) is also important. The Losartan Intervention For Endpoint reduction in hypertension (LIFE) study demonstrates potential benefits beyond blood pressure reduction of prescribing an angiotensin II receptor blocker (ARB) compared with more established therapy in patients with left ventricular hypertrophy (LVH). Losartan-based therapy brought about regression of LVH and reduced incidences of fatal and non-fatal stroke by 25%, new-onset diabetes by 25% and atrial fibrillation by 30% more than atenolol-based therapy for a similar blood pressure control and better tolerability. The Study on COgnition and Prognosis in the Elderly (SCOPE) study, although difficult to interpret, does not contradict an ARB benefit beyond blood pressure lowering in primary prevention linked to targeting the angiotensin type 1 receptor. The findings of the MOrbidity and mortality after Stroke, Eprosartan compared with nitrendipine in Secondary prevention (MOSES) trial suggest clear-cut ARB benefits independent of blood pressure lowering in secondary stroke prevention. Experimental findings and other clinical evidence further support the benefits of ARBs in stroke prevention. Telmisartan is an ARB with a particularly interesting profile for stroke; given the 24-hour efficacy with more pronounced protection against the morning blood pressure surge and peroxisome proliferator-activated receptor-gamma activity at clinical doses. The unique properties of telmisartan for secondary stroke prevention are being tested in the Prevention Regimen For Effectively avoiding Second Strokes (PRoFESS) study.

- The long-term efficacy of isradipine, a new dihydropyridine calcium antagonist with marked vascular selectivity, was evaluated in 17 patients with essential hypertension. All had a supine diastolic blood pressure of greater than 95 mmHg with 10 mg pindolol once daily. After a short-term, double-blind, dose-finding, crossover comparison with addition of isradipine or placebo twice daily, they continued on pindolol and their optimal dose of isradipine in a single-blind, long-term follow-up study. Eighteen patients were recruited but one male patient discontinued treatment after 2 weeks due to ankle oedema and will not be accounted for in the overall evaluation. There were 11 males and six females with a mean age of 56 +/- 10 years. In the short-term study on the optimal dose of isradipine (5.1 mg twice daily) blood pressure was lowered by 24/18 mmHg (P less than 0.001). No change in heart rate was seen despite the substantial drop in blood pressure. In the long-term study the patients were seen for a mean follow-up time of 12.5 months (range 4-17 months). After the longest follow-up time mean arterial pressure was 107.0 +/- 7.4 compared with 120.1 +/- 8.2 mmHg after placebo baseline [delta = 13 mmHg (11%), P less than 0.001, n = 17]. The heart rate was unchanged (delta = 0.2 beats/min, 95% confidence limits -3, +3), and so was ankle circumference (delta = 0.12 cm, 95% confidence interval, -1, +1). On the other hand, mean weight was reduced by 2 kg from 90 kg (P less than 0.05, n = 17).(ABSTRACT TRUNCATED AT 250 WORDS)
