In 14 patients with myocardial infarction the degree of verapamil binding with blood erythrocytes after a single oral administration (80 mg/kg) and the dependence pharmacological effect, the minute heart output (+ % MOC), on verapamil content in plasma and erythrocytes were studied. Intraindividual variability of verapamil distribution coefficients between erythrocytes and plasma (RBC/Ptot) is 9.7 +/- 2,3%, and it differs reliably from values of inter-individual variability of this index (33.7 +/- 3.3%).
