Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/2825712

Carbazeran is a potent PDE-II and PDE-III inhibitor. Potently inhibits cAMP hydrolysis. Shows chronotropic and inotropic effect in vivo (EC50 = 100 μM, ionotropic effects, independent of adrenergic mechanisms). Carbazeran is a potent cardiac stimulant. Phosphodiesterase inhibition and elevation of intracellular cyclic AMP concentration may be involved, at least in part, in carbazeran`s cardiac effect.

Sample Use Guides

In Vivo Use Guide

When administered orally to the dog at a dose level of 5mg/kg the compound elicits a marked inotropic response, causing a 60% increase in the maximum rate of pressure change during systole measured via an indwelling pressure transducer in the left ventricle. When administered by i.v. infusion to human subjects at dose levels up to 1.28 mg/kg a dose-related increase in myocardial contractility was observed, judged from changes in systolic time intervals. However, when human volunteers received single oral doses of up to 350mg (i.e. approximately 5 mg/kg) no effects on the heart or circulation were observed.

In Vitro Use Guide

Carbazeran (9.1 x 10(-6) M-1.2 x 10(-3) M) produced concentration-dependent positive inotropic responses of papillary muscle preparations from rabbit heart.
