Investigation of drugs in ambulant patients

In contrast to the drug testing under clinical conditions, many other problems appear in regard to outpatients. These investigations were carried out on 49 outpatients with various degrees of angina pectoris under the conditions of an intraindividual comparison with d,l-oxyfedrine (Myofedrin), l-oxyfedrine (ildamen) or placebo for a period of 16 weeks and a daily dose of 48 mg applied orally altogether. The severity degrees of the angina pectoris were diminished after the chronic application of l- and d,l-oxyfedrine. There are no differences in the activity and side-effects.
