What is Camptosar?

Camptosar is an FDA (U.S. Food and Drug Administration) approved medication manufactured by Pfizer Inc. Camptosar is a topoisomerase inhibitor indicated for:

  • First-line therapy in combination with 5-fluorouracil and leucovorin for patients with metastatic carcinoma of the colon or rectum
  • Patients with metastatic carcinoma of the colon or rectum whose disease has recurred or progressed following initial fluorouracil-based therapy

Topoisomerase inhibitors are antineoplastic agents that interfere with the action of topoisomerase enzymes (topoisomerase I and II). Topoisomerase enzymes control the manipulation of the structure of DNA necessary for replication.

Early and late forms of diarrhea can occur. Early diarrhea may be accompanied by cholinergic symptoms which may be prevented or reduced by atropine. Late diarrhea can be life-threatening and should be treated with loperamide. Monitor patients with diarrhea and give fluid and electrolytes as needed. Use antibiotic therapy if you develop ileus, fever, or severe neutropenia. Interrupt treatment and reduce subsequent doses if severe diarrhea occurs.

What doses of Camptosar are available?

Camptosar is available in injection form, in the following doses: 2 mL-fill vials containing 40 mg irinotecan hydrochloride injection, 5 mL-fill vials containing 100 mg irinotecan hydrochloride injection, 15 mL-fill vials containing 300 mg irinotecan hydrochloride injection.
