IC50: Adrenergic receptor

Dibenamine (100 nM-10 μM) attenuates the degree of cocaine-induced increase in sensitivity to acetylcholine without any effect on acetylcholine-contraction in isolated vas deferens of guinea pig. Additionally, the degree of dibenamine-induced inhibition dependent on the concentration of dibenamine and inversely related to the concentration of cocaine.

Dibenamine hydrochloride (subcutaneous injection; 25 mg/kg; 48 and 24 hr before the administration of CCl4) decreases the CHCl3, levels at 2 and 6 hr by 30-50 percent, but did not appreciably affect the half-life of CHCl3, in the liver.Pretreatment with Dibenamine apparently slows the conversion of Ccl4 to CHCL3.
