Clinical evaluation of Brinaldix. A new oral diuretic.
(3/6)
'Brinaldix', a new non-thiazide oral diuretic, has been used in a trial on three normal subjects and fourteen patients with oedema from various causes. It is a potent salidiuretic and proved superior to bendrofluazide in 10 out of 14 patients. It produced a substantial potassium diuresis, and we are of the opinion that potassium supplements should be given in conjunction with it. In one normal subject it produced a period of postural hypotension; no other major side-effects were noted. (+info)
The effect of once daily beta-adrenoceptor blocker-thiazide diuretic combination on the ambulatory blood pressure.
(4/6)
1 We have assessed the efficacy of Viskaldix, a combination of pindolol 10 mg and clopamide 5 mg using continuous intra-arterial ambulatory blood pressure monitoring. 2 Fourteen of the sixteen patients entered were studied on no therapy and following a minimum of 6 weeks at a constant dosage of Viskaldix. 3 Viskaldix produced a marked and consistent reduction of the blood pressure over the 24 h. The diurnal variation in the heart rate was decreased. 4 The results were compared with those of a similar study with once-daily pindolol where there was control during the day but not in the early morning when the blood pressures rose rapidly.

Patients compliance in hypertension--the importance of number of tablets.
(5/6)
The importance of number of tablets for patient compliance was investigated in 160 patients with mild-moderate essential hypertension treated with a beta-adrenoceptor blocker and a thiazide diuretic. Mean BP at entry 146 +/- 16/92 +/- 8 mm Hg. All patients were given pindolol 10 mg and clopamide 5 mg in one combination tablet or in separate tablets for 4 months respectively. Approximately 90% of the patients took greater than 90% of the prescribed dose throughout the study. Mean BP decreased progressively and heart rate increased slightly. Side effects were more frequently reported during the first month of the study than previously, and 30 patients discontinued the treatment. No differences in this respect were seen between 1 and 2 tablets daily. Approximately 75% of the patients preferred 1 tablet daily, but combining two drugs in one tablet had no effect upon compliance. (+info)
Different concepts in first-line treatment of essential hypertension. Comparison of a low-dose reserpine-thiazide combination with nitrendipine monotherapy. German Reserpine in Hypertension Study Group.
(6/6)
Low-dose combination therapy has been proposed as a rational first-line approach to hypertension treatment. We compared the efficacy and tolerability of the fixed combination of reserpine (0.1 mg) plus the thiazide clopamid (5 mg) with its single components and the calcium-antagonist nitrendipine (20 mg) in a randomized, double-blind, parallel study of 273 hypertensive patients with diastolic blood pressure (BP) between 100 and 114 mm Hg. The four groups did not differ regarding baseline characteristics (mean age, 58 years; 51% men; mean BP after a 2-week placebo period, 158 to 160/103 to 104 mm Hg). After 6 weeks of treatment with one capsule daily, mean reductions in sitting BP from baseline at 24 hours after dosing in the reserpine-clopamid combination, reserpine, clopamid, and nitrendipine groups were -23.0/-17.1, -14.0/-11.7, -13.6/-11.9, and -11.6/-12.3 mm Hg, respectively (2P < .01). The corresponding normalization rates (diastolic BP < 90 mm Hg) were 55%, 40%, 36%, and 33% (2P = .11). All patients whose BP had not been normalized at this point received two capsules of the respective medication once daily from weeks 7 to 12. At week 12, mean BP reductions were -25.7/-18.1, -14.6/-12.2, -17.7/-13.4, and -14.9/-15.3 mm Hg in the four groups, respectively (2P < .01). The respective normalization rates were 69%, 35%, 39%, and 45% (2P < .0001). Linear regression modeling indicated that reserpine and clopamid combined acted more than additively. As regards tolerability, adverse experiences were observed in 27%, 28%, 29%, and 48% of patients, respectively (2P < .05). The respective rates of premature discontinuation because of adverse effects were 3%, 3%, 7%, and 13% (2P = .06). In conclusion, a low-dose combination of reserpine and clopamid lowered BP significantly more than both the components alone and nitrendipine. Moreover, the combination was tolerated as well as its components and significantly better than nitrendipine. Thus, the use of this low-dose reserpine-thiazide combination appears to be a rational alternative to conventional monotherapy in the first-line treatment of hypertension. (+info)
