Mechanism:

Temsirolimus (Toricel®) is a kinase inhibitor that prohibits the function of the oncoprotein kinase mTOR, which is a key oncoprotein in the growth of tumor cells. Temsirolimus also inhibits cell division and tumor growth through inhibiting mTOR signaling, which can also lead to apoptosis.1

Contraindications:

Serious reactions to temsirolimus include: hypersensitivity reactions (flushing, chest pain and/or difficulty breathing), hyperglycemia, interstitial lung disease, elevated serum triglyceride and cholesterol levels, bowel perforation and renal failure. Women should avoid becoming pregnant while on temsirolimus treatment and men undergoing treatment should use barrier methods of contraception.
