Karmustin Teva

Carmustine, the active ingredient in Karmustin, is a nitrosourea alkylating agent presented as an unspecified strength intravenous solution for intravenous use. It is employed in the treatment of certain primary brain tumors, lymphoma and melanoma in adult patients. GNH USA supplies Karmustin as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, oncology centres worldwide.

Carmustine is used as a chemotherapy agent targeting rapidly dividing cells in several malignant conditions.

- Primary brain tumors (e.g., glioblastoma): helps to reduce tumor size and prolong survival. - Lymphoma: contributes to disease control when combined with other chemotherapeutics. - Melanoma: used in selected cases to achieve tumor regression.

Carmustine may cause a range of adverse reactions that vary in frequency and severity.

Common Side Effects: - Nausea and vomiting: mild to moderate gastrointestinal upset. - Myelosuppression: reduced white blood cells, red blood cells, and platelets. - Fatigue: generalized tiredness during treatment. - Alopecia: temporary hair loss. - Hepatotoxicity: mild elevation of liver enzymes. - Pulmonary toxicity: early signs of lung irritation.

Serious or Rare Side Effects: - Severe bone marrow failure: pancytopenia requiring transfusion. - Acute respiratory distress syndrome: severe lung injury. - Seizures: neurologic events in susceptible patients. - Secondary malignancies: rare development of new cancers. - Renal impairment: significant decline in kidney function. - Allergic reactions: anaphylaxis or severe skin rash.

Carmustine requires careful monitoring due to its potent cytotoxic activity.

- Monitor blood counts: perform regular CBC to detect myelosuppression. - Assess liver function: check hepatic enzymes before each cycle. - Evaluate pulmonary status: baseline and periodic lung function tests are advised. - Avoid concurrent nephrotoxic drugs: reduce risk of renal injury. - Use contraception: advise patients of potential reproductive toxicity. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Carmustine can interact with other medications, altering efficacy or toxicity.

Major Interactions (Avoid): - Other alkylating agents: may cause excessive bone marrow suppression. - Anticoagulants: increased risk of bleeding due to thrombocytopenia. - Live vaccines: heightened risk of infection.

Moderate Interactions (Monitor Closely): - CYP450 inducers (e.g., rifampin): may reduce Carmustine plasma levels. - Antiemetics (e.g., ondansetron): may affect nausea control. - Hepatotoxic drugs (e.g., acetaminophen high dose): could exacerbate liver toxicity.
