Abstract
The invention provides improved methods for coadministration of colchicine with drugs metabolized by CYP3A4 (anciently referred to as cytochrome P450 isozyme 3A4) or the P-glycoprotein transporter, but not both. The method enables non-toxic coadministration of colchicine and the second drug at their ordinary levels safely and effectively without reducing the dose or frequency for either drug.
