The pharmacokinetic studies of propranolol following the application of the propercuten transdermal therapeutic system were performed in conscious rabbits previously assigned to 3 groups. Different forms of propercuten (forte and mite) were used in different groups, different areas of its application being employed. Pulsed intravenous injections of propranolol were given to Group 1 rabbits to conduct another series of pharmacokinetic studies. The rate of drug administration to the systemic bed was 0.08 mg/h per cm propercuten. The constant injection rate was maintained during 5 days, but when propercuten was withdrawn the elimination time of propranolol was 24 hours.
