Colchicine interacts with the P-glycoprotein transporter, and the CYP3A4 enzyme involved in drug and toxin metabolism. [ 26 ] [ 42 ] Fatal drug interactions have occurred when colchicine was taken with other drugs that inhibit P-glycoprotein and CYP3A4, such as erythromycin or clarithromycin .
AUC it is a measure of the drug exposure in the body over time. By inhibiting CYP3A4, macrolide antibitiotics, such as erythromycin and clarithromycin, but not azithromycin, can significantly increase the AUC of the drugs that depend on it for clearance, which can lead to higher risk of adverse effects or drug-drug interactions. Azithromycin ...
Clarithromycin has been observed to have a dangerous interaction with colchicine as the result of inhibition of CYP3A4 metabolism and P-glycoprotein transport. Combining these two drugs may lead to fatal colchicine toxicity, particularly in people with chronic kidney disease. [9]
Colchicine, a drug for gout, interferes with the function of the structural protein tubulin, while digitalis, a drug still used in heart failure, inhibits the activity of the carrier molecule, Na-K-ATPase pump. The widest class of drugs act as ligands that bind to receptors that determine cellular effects.
Despite dosing issues concerning its toxicity, colchicine is also a popular medicine at low doses, prescribed in the treatment of gout, [88] familial Mediterranean fever, pericarditis, and Behçet's disease. It is also being investigated for use as an anti-cancer drug. Certain drugs and conditions can interfere with colchicine metabolism and ...
P-gp is a 170 kDa transmembrane glycoprotein, which includes 10–15 kDa of N-terminal glycosylation.The N-terminal half of the protein contains six transmembrane helixes, followed by a large cytoplasmic domain with an ATP-binding site, and then a second section with six transmembrane helixes and an ATP-binding domain that shows over 65% of amino acid similarity with the first half of the ...
