Introduction: DMF

The Drug Master File is a confidential document submitted to the regulatory authorities by pharmaceutical manufacturers. Detailed information on the production process, quality control and safety of an active pharmaceutical ingredient API is included. The Drug Master File (DMF) shall serve as a reference for regulatory authorities in the approval process of medicinal products. In this blog, we will take a look at the importance of DMF for 5-Fluorouracil (5-FU), its mechanism of action, clinical strategies, global market impact, and role of top pharma database service provider in India for providing insights related to it.

5-Fluorouracil (5-FU)

In many cancers, 5-FU is used and colorectal cancer is widely used. It's been around since the 1950s, when researchers discovered that rat hepatoma metabolized uracil, a pyrimidine base found in RNA, more rapidly than normal tissues. This led to the development of fluoropyrimidines, with 5-FU at the front.

Mechanism of Action

There are two major mechanisms responsible for the cytotoxicity of 5-FU:

  1. Incorporation into RNA and DNA: During replication, the metabolites of 5FUs are misincorporated into RNA and DNA disrupting normal cell processes. 
  2. Thymidylate Synthase (TS) Inhibition: TS, a key enzyme involved in the synthesis of nucleotides, is inhibited by 5-FU. The production of thymidine is reduced, impairing DNA replication and repairing.

Clinical Applications:

  • Cancer Treatment: In the treatment of various cancers, including colorectal, breast, stomach, and skin cancers, 5-FU is widely used. It is often administered intravenously as part of combination chemotherapy regimens or as a continuous infusion.
  • Topical Treatment: For the treatment of actinic keratoses, basal cell carcinomas and superficial squamous cell carcinomas, 5-FU is used in dermatology. It is an efficient treatment for noninvasive, skin cancer because of its ability to stimulate local cytotoxicity.

Side Effects:

Despite its therapeutic benefits, 5-FU therapy is associated with a spectrum of side effects ranging from mild to severe. Common side effects are nausea, vomiting, diarrhoea, mucositis, myelosuppression and skin reactions such as erythema, desquamations or photosensitivity.

Clinical Strategies

Several strategies have been identified to increase the anticancer activity of 5-fluorouracil:

  • Leucovorin and Methotrexate Co-treatment: Several strategies have been identified to increase the anticancer activity of 5fluorouracil.
  • Predictive Biomarkers: mRNA and protein expression levels of TS predict tumor sensitivity to 5-FU.
