Drug profile
Sirolimus (Rapamycin)
mTOR inhibitor that suppresses T-cell proliferation and angiogenesis.
Why this drug?
Rapamycin inhibits mTOR signaling implicated in tuberous sclerosis complex (TSC) hamartoma growth, leading to approved use for TSC-associated SEGA and renal angiomyolipoma.
Known risks
- Immunosuppression
- Hyperlipidemia
- Mouth ulcers
- Impaired wound healing
Evidence behind this
