Drug Interaction Report
4 potential interactions and/or warnings found for the following 2 drugs:
- ezetimibe / rosuvastatin
- saquinavir
Interactions between your drugs
saquinavir rosuvastatin
Applies to: saquinavir, ezetimibe / rosuvastatin
Saquinavir may significantly increase the blood levels of rosuvastatin. This can increase the risk of side effects such as liver damage and a rare but serious condition called rhabdomyolysis that involves the breakdown of skeletal muscle tissue. In some cases, rhabdomyolysis can cause kidney damage and even death. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. Let your doctor know immediately if you have unexplained muscle pain, tenderness, or weakness while taking rosuvastatin or similar medications, especially if these symptoms are accompanied by fever or dark colored urine. You should also seek immediate medical attention if you develop fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
saquinavir ezetimibe
Applies to: saquinavir, ezetimibe / rosuvastatin
Consumer information for this interaction is not currently available.
MONITOR: Coadministration with inhibitors of the organic anion transporting polypeptides (OATP) 1B1 and/or 1B3 may increase the plasma concentrations and effects of ezetimibe, which is a substrate of these hepatic uptake transporters. When a single dose of ezetimibe was taken with steady state bempedoic acid, a weak inhibitor of OATP1B1 and 1B3, the systemic exposure (AUC) and maximum plasma concentration (Cmax) of total ezetimibe (ezetimibe and its glucuronide form) increased by 1.6- and 1.8-fold, respectively. These increases were not considered clinically significant. When coadministered in patients on cyclosporine, a stronger OATP1B1 and 1B3 inhibitor, the AUC and Cmax of total ezetimibe increased by approximately 3.4- and 3.9-fold, respectively, compared to the exposure observed in a historical healthy control population. In another study, a renal transplant patient with severe renal dysfunction who was receiving multiple medications, including cyclosporine, demonstrated a 12-fold greater exposure to total ezetimibe compared to healthy subjects. The exact mechanism of the interaction with cyclosporine is unknown, but its ability to inhibit OATP1B1 and 1B3 may play a role. Data are not available for all inhibitors of OATP1B1 and/or 1B3 with ezetimibe.
MANAGEMENT: Caution and additional monitoring may be advisable if ezetimibe is used concurrently with OATP1B1 and/or 1B3 inhibitors. Additional monitoring of liver enzymes and creatine kinase (CK) may be necessary. Patients should also be advised to promptly report unexplained muscle pain, tenderness, or weakness to their healthcare provider.
ezetimibe rosuvastatin
Applies to: ezetimibe / rosuvastatin, ezetimibe / rosuvastatin
Using ezetimibe together with rosuvastatin can increase the risk of side effects such as liver damage and a rare but serious condition called rhabdomyolysis that involves the breakdown of skeletal muscle tissue. In some cases, rhabdomyolysis can cause kidney damage and even death. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Let your doctor know immediately if you have unexplained muscle pain, tenderness, or weakness while taking these medications, especially if these symptoms are accompanied by fever or dark colored urine. You should also seek immediate medical attention if you develop fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Drug and food interactions
saquinavir food
Applies to: saquinavir
Food can enhance the levels of saquinavir in your body. Saquinavir should be taken with meals or within 2 hours after eating. This will make it easier for your body to absorb the medication. Grapefruit can raise the levels of saquinavir in your body. Discuss the use of grapefruit products with your doctor. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
