PURPOSE The objective of this study was to explore the pharmacology of GSK961081, a bi-functional bronchodilator, in healthy volunteers. METHODS Two randomized, double-blind, placebo-controlled studies were conducted. Following optimization of the propranolol dosing regimen (study 1), we conducted a five-period crossover study (study 2) in which subjects received the following treatments: dry...

The effects of oral acebutolol, a cardioselective f-adrenergic blocking agent with partial agonist activity were compared with those of oral propranolol, a noncardioselective agent devoid of partial agonist activity, on the exercise tolerance and anginal pattern in 46 male patients with chronic stable angina pectoris. A 28-week, multicenter, placebo-controlled, randomized, double-blind, crossov...

The duration of action of single oral doses of 80 and 160 mg of propranolol during acute and sustained therapy was studied in nine patients with stable, exercise-induced angina pectoris. Plasma propranolol levels peaked 2 hours after both doses during acute and sustained therapy, but there were wide variations between individuals in plasma concentration with both dosage schedules. Plasma half-l...

There is a need to develop dosage forms suitable for children improve drug treatment. Extemporaneous compounding of drugs one way meet these needs. However, excipients generally considered as safe in adults may not be appropriate intended children. The aim was optimize the composition two pediatric liquid preparations by substituting paraben microbiological preservative and ethanol solubilizer,...

In order to study the mode of action of beta-adrenoreceptor antagonists in essential tremor the efficacy of single oral doses of 2, 4 and 10 mg LI 32-468, a peripherally acting, selective beta-2 adrenoreceptor antagonist, was compared with a single oral dose of 120 mg propranolol in a randomised, double blind, placebo controlled trial. Both the lowest dose of LI and propranolol were shown to be...

The duration of action of single oral doses of 80 and 160 mg of propranolol during acute and sustained therapy was studied in nine patients with stable, exercise-induced angina pectoris. Plasma propranolol levels peaked 2 hours after both doses during acute and sustained therapy, but there were wide variations between individuals in plasma concentration with both dosage schedules. Plasma half-l...

LID retraction and lid lag in thyrotoxicosis have been diminished by intramuscular reserpine (Canary, 1957), oral guanethidine (Waldstein, West, Lee, and Bronsky, 1964), and oral propranolol (Buckfield and Davis, 1966), while the increasing availability of local ophthalmic preparations of adrenergic blocking agents has resulted in the local use of propranolol (Sneddon and Turner, 1966), phentol...

The effect of incremental dosages of oral propranolol (mean peak dose of 165 +/- 13 mg/day) of left ventricular ejection fraction, ejection rate and regional wall motion was studied sequentially in 22 stable, resting patients with coronary artery disease using a geometry-independent first-pass radionuclide angiocardiographic technique. All patients improved clinically, in association with a fal...
