Interaction between Carvedilol and Venetoclax
Major
Absorption
| ID | DDInter305 and DDInter1926 |
| Interaction | Coadministration with P-glycoprotein (P-gp) inhibitors may increase the plasma concentrations of venetoclax, which is a substrate of this efflux transporter. |
| Management | Concomitant use of venetoclax with P-gp inhibitors should generally be avoided. If coadministration is required, the manufacturer recommends that venetoclax dosage be reduced by at least 50%. The dosage used prior to initiating the P-gp inhibitor may be resumed 2 to 3 days after discontinuation of the inhibitor. |

Potential Metabolism Interactions
Substrate-Substrate Interaction：If more than one drug is metabolized by the same CYP, it is possible that its metabolism is inhibited because of the competition between the drugs. That means, it can be useful to lower the dosage of the drugs in the drug-cocktail because they remain longer in the organism than in monotherapy.
Inhibitor-Inhibitor Interaction：Combining two or more inhibitors of one CYP, should be compensated by lowering the dosage of these drugs because the metabolism is reduced and the drugs remain longer in the organism than in monotherapy. Not adapting the dosage bears the risk of even more side effects.
Inhibitor-Substrate Interaction：Combining drugs that have inhibitory effect and are substrates of one particular CYP, should be compensated by lowering the dosage. They rest longer in the organism than in monotherapy. Not adapting the dosage bears the risk of even more side effects.
