Interactions between your drugs
PHENobarbital telisotuzumab vedotin
Applies to: Solfoton (phenobarbital), telisotuzumab vedotin
Coadministration with potent inducers of CYP450 3A4 may decrease exposure to unconjugated monomethyl auristatin E (MMAE), the anti-mitotic and cytotoxic component of telisotuzumab vedotin. Telisotuzumab vedotin is an antibody-drug conjugate (ADC) that releases MMAE via proteolytic cleavage, and MMAE has been shown in vitro to be primarily metabolized by CYP450 3A4. Concomitant use of telisotuzumab vedotin with rifampin, a potent CYP450 3A4 inducer, is predicted to decrease unconjugated MMAE exposure (AUC) by 70% according to the product labeling. However, the clinical relevance is unknown, since the intact ADC containing the antibody component is required to bind to c-Met, the cell surface receptor for hepatocyte growth factor, which allows for internalization and cleavage by lysosomal proteases to enable intracellular delivery of MMAE.

Drug and food/lifestyle interactions
PHENobarbital food/lifestyle
Applies to: Solfoton (phenobarbital)
GENERALLY AVOID: Concurrent acute use of barbiturates and ethanol may result in additive CNS effects, including impaired coordination, sedation, and death. Tolerance of these agents may occur with chronic use. The mechanism is related to inhibition of microsomal enzymes acutely and induction of hepatic microsomal enzymes chronically.
MANAGEMENT: The combination of ethanol and barbiturates should be avoided.
