Description

One macrolide drug, Sirolimus Tablets was approved for treatment of:

  • lymphangieiomyomatosis, a progressive systemic condition that causes cystic lung deterioration.
  • Coat coronary stents: A coronary stent is a tube-shaped device used to enlarge the vein that leads to or originates from the heart and transports blood.
  • Prevent organ transplant rejection by inhibiting the immune system, which lowers the likelihood of organ transplant rejection.

Dosage and Side Effects

With or without food, sirolimus should be taken orally at roughly the same time every day. It is recommended to take sirolimux tablets whole, along with water. The tablet must not be chewed, opened, or damaged.

A decrease in glucose tolerance and insulin sensitivity, dizziness, leg swelling, thrombocytopenia, pain, headache, abdominal pain, acne, chest pain, hypertension, hypertriglyceridemia, fever, hypercholesterolemia, creatinine, anemia, nausea, urinary tract infection, arthralgia, sore throat, and dizziness are the most frequent side effects of sirolimus.

Warning and Precautions

  • Sirolimus 1 mg should not be used by those with a known hypersensitivity to the drug. The safety of LAM treatment using sirolimus has not been assessed in individuals under 18 years old. 

  • Using sirolimus may elevate the risk of developing type 2 diabetes. Lung toxicity, particularly in lung transplant cases, can be a severe complication of sirolimus therapy.

  • There are warnings associated with sirolimus use in transplants as it might heighten mortality risk due to an increased susceptibility to infections. Sirolimus tablets could potentially heighten the risk of skin cancers with exposure to sunlight or UV radiation, as well as the risk of developing lymphoma.

  • Individuals taking sirolimus 1 mg face an increased likelihood of experiencing impaired or delayed wound healing, especially if their body mass index exceeds 30 kg/m2. Sirolimus dosage, also known as rapamycin dosage, is metabolized by the CYP3A4 enzyme and acts as a substrate for the P-glycoprotein (P-gp) efflux pump. 

  • Consequently, inhibitors of either protein may escalate sirolimus concentrations in the bloodstream, while P-gp and CYP3A4 inducers may lower these concentrations.

  • Women capable of bearing children should be advised to avoid pregnancy while on or during Rapamune therapy. 

  • Since sirolimus is not absorbed through the skin, no special precautions are necessary. However, if direct contact occurs with the skin or mucous membranes, immediate washing with soap and water is recommended, along with rinsing the eyes with plain water.
