Time course changes in antianginal effect were evaluated for obsidan, corinfar and finoptin under 12-week administration in 104 patients with stable angina pectoris. The response to finoptin appeared to rise while for obsidan and corinfar it was stable. Some patients with stable angina developed clinical tolerance to corinfar.
