When stenosis or occlusion occurs in the coronary artery, blood supply to the periphery is obstructed, the myocardium enters an ischemic state, and symptoms of coronary insufficiency occur. The essential action of coronary vasodilators is to relax the smooth muscles of the coronary arteries, which causes dilation of coronary vessels and an increase in coronary blood flow. Typical drugs having such effects are nitrite drugs such as nitroglycerin and isosorbide cinitrate.2-(4-benzylpiperidino)=1-( 4-Hydroxyphenyl)globanol tartrate is known as a compound that is effective in improving symptoms such as dizziness, headache, depression, anxiety, and excitement associated with cerebral infarction sequelae and cerebral hemorrhage sequelae [Kabane et al., Pharmacology. and Therapy, Vol. 5, No. 10, p. 3107 (1977)], the coronary vasodilator effect of this compound and compounds having similar skeletons is unknown.
