CLINICAL PHARMACOLOGY OF RAPACT
Everolimus is a prohibitor of mTOR, links at peak compatibility to FK506 binding protein 12, through producing drug complex which prevents the productive of mTOR. This inhibition reduces the activity of effectors downstream, which may lead to stoppage of cell progression from G1 into S phase, finally causes cell growth arrest and apoptosis.Rapactalso prohibits the expression of hypoxia-inducible factor, causing to a reduces in the expression of vascular endothelial growth factor. The results of everolimus prevention of mTOR is a reduction in cell multiplication, angiogenesis, and glucose uptake.
The time to peak plasma concentration of Rapact 10mg occurs between 1 to 2 hours.
The drug Rapact 10mg has Albumin human plasma protein bound of 74%.
In hepatic Rapact 10mg metabolism is take place, which is a substrate of CYP3A4.
The Rapact 10mg metabolism will occur through 3 processes;
• Three monohydroxylated metabolite,
• Two hydrolytic rings opened products,
• Phosphatidylcholine conjugate of Everolimus.
The drug excretion primarily through 5% in urine; the parent compound has been detected in urine or feces.
The drug half-life period is 30 hours
Rapact 10mg tablets should be given with or without food.

Grape juice interaction:
avoid these concomitant uses with grape juice Causes increasing blood levels of Everolimus Nephrotoxicity: While using Rapact 10mg in renal impaired patients’ Renal function should be monitored frequently; drug use with caution

Blood glucose level should be monitored
Drug – Drug interaction
Interaction of Rapact 10mg with strong inhibitor of CYP3A4, or P-gp, cause reducing the efflux of Everolimus and high plasma concentration of Everolimus.
Concomitant use of Rapact 10mg with strong CYP3A4 inducers, will increasing the disclosure of Everolimus.
Interaction of Rapact 10mg with cyclosporine will increasing the AUC level of Everolimus frequently.
Interaction of ketoconazole with Rapact 10mg tablet or other CYP3A4 inhibitors will increasing the plasma concentration and AUC of Everolimus.
Combination of Rapact 10mg with verapamil leads to increasing the plasma concentration of Everolimus.
Interaction of Rapact 10mg with Atorvastatin or pravastatin leads to rhabdomyolysis, due to increasing concentration of lipid lowering agents.
When Rapact 10mg combination with rifampicin will reduces the AUC of Everolimus
The over dosage of Everolimus is limited, if over dosage occurs patient must be provide with supportive measures. And monitor evidence of toxicity in Everolimus over dosage
If the patients missed dose, patients must consult with medical practitioner and follow the instructions given by them. Or missed dose should be avoid and follow the regular dosing schedule.
