Description

Inamrinone (Amrinone) is a positive inotropic cardiotonic with vasodilator properties, phosphodiesterase inhibitory activity, and the ability to stimulate calcium ion influx into the cardiac cell. Inamrinone is a phosphodiesterase inhibitor (PDE3), resulting in increased cAMP and cGMP which leads to an increase in the calcium influx like that caused by beta-agonists resulting in increased inotropic effect. Inamrinone is used in the treatment of congestive heart failure.

Sample Use Guides

In Vivo Use Guide
Congestive heart failure IV Initially, 0.75 mg/kg as a slow (over 2–3 minutes) direct injection; if warranted, may administer a supplemental direct IV dose of 0.75 mg/kg 30 minutes after the initial dose.1 60 Direct IV injection is followed by an IV infusion of 5–10 mcg/kg per minute. Duration of therapy determined by clinical response and tolerance to adverse effects.
Route of Administration: Intravenous
In Vitro Use Guide
Inamrinone inhibited human platelet aggregation at 10,800 s(-1) in a dose-dependent manner with the IC(50) value of 61 +/- 8 uM (mean +/- S.D.), Inamrinone significantly inhibited platelet aggregation at 1200 s(-1) only at highest concentration tested (100 uM)
