DESCRIPTION
Everotas 5mg is a derivative of Rapamycin (sirolimus) and works similarly to Rapamycin as an mTOR (mammalian target of rapamycin) inhibitor.
It is normally used as an immunosuppressant to prevent rejection of organ transplants.
In a similar fashion to other mTOR inhibitors Everolimus' effect is solely on the mTORC1 protein and not on the mTORC2 protein.
INDICATION
Everotas 5mg tablets are mainly indicated for the treatment of Renal carcinoma.
Everotas 5mg tablets are mainly indicated for the treatment of Breast carcinoma.
Everotas 5mg tablets are mainly indicated for the treatment of Brain carcinoma.
Everotas 5mg is also used in various advanced stage cancer in stomach, intestines or pancreas.
MECHANISM OF ACTION
Everolimus is an mTOR prohibitor, joints at high compatibility to FK506 binding protein 12, via producing drug complex whichinhibits the specific of mTOR.
This inhibition decreases the activity of effectors downstream, that may cause blockage of cell progression from G1 into S phase, subsequently causes cell growth arrest and apoptosis

DRUG INTERACTION
- Everotas 5mg interaction with strong inhibitor of CYP3A4, or P-gp, leads to cause decreasing the efflux of Everolimus and increase the plasma concentration of Everolimus
- Combination of Everotas 5mg with verapamil leads to increasing the plasma concentration of Everolimus.
- Combination of Everotas 5mg with Atorvastatin or pravastatin causes rhabdomyolysis, due to increasing concentration of lipid lowering agents.
- Everotas 5mg combination with strong CYP3A4 inducers, causes increasing the exposure of Everolimus.
- Concomitant use of Everotas 5mg with cyclosporine causes increasing the AUC level of Everolimus frequently.
- Everotas 5mg tablet is interaction with ketoconazole or other CYP3A4 inhibitors causes increasing the plasma concentration and AUC of Everolimus.
- Concomitant use with erythromycin causes increasing in AUC of Everolimus.
