Pharmacologic Category

Antineoplastic Agents; Alkylating Agents. (ATC-Code: L01AD04).

Mechanism of action

Precise mechanism unknown. Alkylates DNA, causing interstrand cross-linking. Weak alkylator compared with other nitrosoureas. Inhibits DNA synthesis in bacterial and mammalian cells. Blocks progression of cells into mitosis (cycle-phase non-specific). Does not inhibit RNA or protein synthesis. Marked specificity for pancreatic-β and exocrine cells. Active against Gram-positive and Gram-negative bacteria. Cytotoxicity precludes use as anti-infective agent.

Therapeutic use

Metastatic islet cell carcinoma of pancreas. Carcinoid tumor and syndrome. Hodgkin’s disease. Palliative treatment of colorectal cancer.

Pregnancy and lactiation implications

Contraindicated in pregnant or nursing women.

Unlabeled use
