The antihypertensive activity of timolol (Blocadren, FROSST-MSD), a new beta blocking agent, was assessed in a single blind crossover placebo-controlled study in 14 patients with essential hypertension. Ten patients completed the trial. The average standing pressure during the placebos periods was 168/109mmHg and during the periods on treatment with timolol the average standing pressure was 139/92mmHg. All 10 patients showed some hypotensive response. The average daily dosage was 21 mg with a range of 15-30 mg. Four patients achieved optimal levels of blood pressure by the end of one week's therapy with the maximum time required being four weeks. Timolol appears to be an effective antihypertensive agent. Side effects were insignificant.

A study of a new beta-adrenergic blocking drug TIMOLOL (Blocadren) in the treatment of essential hypertension has been undertaken. Twelve hypertensive patients previously undiagnosed and untreated were studied. Results with a twice a day dose of the drug showed a satisfactory fall in systolic and diastolic pressures in all but one patient, who was withdrawn from the trial because of excessive bradycardia. Apart from bradycardia, no serious side effects were observed in the patients. Observation over longer period is advocated to determine the place of Timolol in our antihypertensive armamentorium.

Up to now, the experiments carried out throughout the world with enalapril have been most encouraging. The drug gives good, even excellent responses in 54 to 66 % of patients with essential hypertension, and it is at least as effective as diuretics and beta-blockers. Compared with those of diuretics, the effects of enalapril confirm that the best responders are those patients who are most dependent on the renin-angiotensin system. When a diuretic is administered concomitantly with enalapril, almost all patients respond and the therapeutic effect is well maintained in long term. Blocadren or alpha-methyldopa can be added to hydrochlorothiazide, thus providing additional benefits to patients with severe hypertension. Enalapril reduces the undesirable metabolic effects of hydrochlorothiazide, particularly hypokalaemia. Altogether, enalapril and captopril have similar effectiveness, but enalapril is better tolerated and does not seem to produce the side-effects encountered with captopril, notably skin rashes and ageusia. As expected, enalapril and other angiotensin-converting enzyme inhibitors may be associated with azotaemia in patients with bilateral renovascular hypertension.

Overall, the worldwide experience on enalapril to date is very encouraging. The drug produces good to excellent responses in 54 to 66 percent of patients with essential hypertension and is at least as effective as either diuretics or beta blockers. The effects of enalapril compared with those of diuretics confirm that patients more dependent upon the renin-angiotensin system respond better. When hydrochlorothiazide is administered concomitantly with enalapril, almost all patients respond, with good long-term maintenance. In patients with severe hypertension, Blocadren or Aldomet may be added in addition to hydrochlorothiazide and will produce additional benefit. Enalapril attenuates the adverse metabolic effects of hydrochlorothiazide, particularly hypokalemia. Overall, although the efficacy of enalapril and that of captopril are similar, enalapril is better tolerated and does not appear to be associated with any significant occurrence of captopril-type side effects, particularly the skin rash and loss of taste. As expected, enalapril and other converting inhibitors may be associated with azotemia in patients with bilateral renovascular hypertension.
