What drugs interact with ColciGel?
- ColciGel (Colchicinum 4X) is a substrate of the efflux transporter P-glycoprotein (P-gp).
- Of the cytochrome P450 enzymes tested, CYP3A4 was mainly involved in the metabolism of colchicinum.
- If ORAL colchicine is administered with drugs that inhibit P-gp, most of which also inhibit CYP3A4, increased concentrations of colchicinum are likely.
- Fatal drug interactions have been reported.
- Topical application of ColciGel has demonstrated insignificant systemic absorption in animal testing and confirmed in limited human pharmacokinetic evaluations and, therefore, poses a limited risk of clinically significant drug interactions.
- Physicians should, however, ensure that patients are suitable candidates for treatment with ColciGel and remain alert for signs and symptoms of toxicities related to increased colchicinum exposure as a result of a drug interaction.
- Signs and symptoms of ColciGel toxicity should be evaluated promptly and, if toxicity is suspected, ColciGel should be discontinued immediately.
Is ColciGel safe to use while pregnant or breastfeeding?
- No human or animal studies on the effect of ColciGel® (colchicinum 4X) in pregnancy have been conducted.
