Erythromycin cyp inhibitor
WebHow does erythromycin inhibit CYP3A4? Erythromycin has been shown to produce quasi-irreversible inhibition of CYP3A4 in vitro, via formation of a CYP3A4-iron-metabolite complex, and to cause clinically important drug interactions with CYP3A4 substrates (see [3, 4] for recent reviews). WebThe concomitant incubation of hepatocytes with butyrate and erythromycin led to an increased CYP2H1 expression and a less pronounced inhibition of CYP3A37. In in vivo pharmacokinetic experiments, butyrate-fed animals given a single i.m. injection of erythromycin, a slower absorption phase (longer T half-abs and delayed T max ) but a …
