eflornithinebased

Eflornithine-based refers to therapies and products that use eflornithine as the active ingredient. Eflornithine is used in two main domains: systemic treatment for human African trypanosomiasis (sleeping sickness) and a topical cosmetic preparation for reducing facial hair growth. In recent years, regimens combining eflornithine with other drugs have become standard in certain forms of the disease.

Mechanism of action is as an irreversible inhibitor of ornithine decarboxylase, an enzyme essential for polyamine synthesis. By blocking polyamine production, eflornithine disrupts cell proliferation in susceptible organisms, notably Trypanosoma brucei gambiense, the parasite responsible for most West African sleeping sickness. In humans, the drug’s effects reflect its anti-proliferative mechanism and can be dose- and route-dependent.

Medical uses include systemic therapy for second-stage African trypanosomiasis, often given as an intravenous regimen, sometimes in combination with nifurtimox (the NECT regimen) to improve efficacy and reduce treatment duration. Eflornithine is also formulated as a topical cream (eg, eflornithine hydrochloride 11.5%) for cosmetic use to slow the growth of unwanted facial hair in women.

Safety and regulatory status vary by use. Systemic eflornithine can cause hematologic and other adverse effects and requires medical supervision, whereas topical formulations are generally associated with mild local skin irritation and are approved for cosmetic use in appropriate markets. Eflornithine-based therapies are subject to ongoing evaluation for emerging regimens and new indications.
