Sample Use Guides

In Vivo Use Guide

A tablet containing 2 mg of temocapril hydrochloride was administered once a day in the morning, and the monitoring term was for 16 weeks.

Route of Administration: Oral

In Vitro Use Guide

A force of 1.0 g was applied, and the strips were allowed to equilibrate for 90 min. Aortic strips were exposed to 30 nM of angiotensin I (AI), which produced contractions approximately equal to 90% of the maximum response. After three successive contractions of equal size had been obtained, test drugs (CS-622 diacid) was added to the bath. Contractile responses to AI in the presence of a test drug were compared with control responses before the drug was added. The concentration of the drug was increased in a cumulative manner by a ratio of 3 at a 10 min interval to construct a concentration inhibition curve. The IC50 value was determined as the concentration inhibiting by 50% the response to AI
