title: [The comparative efficacy of individually adjusted doses of proxodolol and propranolol for one-time and regular administration in stenocardia patients].
abstract: The comparative efficacy of single and regular doses of the new Russian alpha- and beta-adrenoblocker proxodolol (Pd) and the beta-adrenoblocker propranolol (Pr) was studied in 12 male patients with stable angina on effort. The effect of single doses was evaluated with paired bicycle ergometries (PBE); that of course therapy was assessed with crossover randomized placebo-controlled tests of the two agents. During PBE, an adequate antianginal effect of Pd given in single doses of 0.04-0.08 g was seen in 66.5% and that of Pr used in the same doses was observed in 58.4% (p > 0.05). The exercise tolerance in patients given either agent in a single dose was similar. During 1-month course treatment with Pd in a mean daily dose of 186 +/- 24 mg, anginal episodes caused an over 3-fold reduction, which is similar to the clinical effect displayed by Pr, 182 +/- 25 mg/day. A single dose of Pd of 0.04 g produced a more pronounced chronotropic and antihypertensive effect than did the same dose of Pr. No differences were found during their course therapy. Pd was found to cause no orthostatic antihypertensive phenomenon.
