Interaction between Lenalidomide and Atorvastatin
Major
Synergy
| ID | DDInter1035 and DDInter133 |
| Interaction |
The risk of rhabdomyolysis may be increased during coadministration of lenalidomide with HMG-CoA reductase inhibitors (statins). The mechanism is unknown but may involve additive pharmacodynamic effects.

| Management | European product labeling recommends caution and increased clinical and biological monitoring if lenalidomide is used in combination with statins, especially during the first several weeks of treatment. All patients treated with statins should be advised to promptly report any unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever. |

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.
