What is Ethambutol 400 mg?
Ethambutol 400 mg is an antibiotic medication primarily used in the treatment of tuberculosis (TB). Manufactured by Lupin Limited, this drug plays a crucial role in managing TB infections by inhibiting the growth of Mycobacterium tuberculosis, the bacteria responsible for the disease. Ethambutol is valued for its ability to complement other anti-tubercular agents, boosting the effectiveness of combination therapy.
Designed for oral administration, Ethambutol 400 mg is widely prescribed in Canada and worldwide as a part of standard TB treatment protocols. It is essential for patients and healthcare providers to understand its role, proper use, and safety to maximize therapeutic benefits.
Uses of Ethambutol 400 mg
- Treatment of active tuberculosis infection
- Prevention of resistance when used with other anti-TB drugs such as isoniazid
- Part of combination therapy for multidrug-resistant TB
- Used in latent TB cases when recommended by a physician
How Ethambutol 400 mg Works
Ethambutol acts by inhibiting the synthesis of the bacterial cell wall in Mycobacterium tuberculosis. It targets the arabinosyl transferases, enzymes vital for cell wall biosynthesis, thereby weakening the bacteria and preventing their replication. This mechanism helps reduce the bacterial load, allowing the body's immune system to more effectively combat the infection. Because Ethambutol is bacteriostatic rather than bactericidal, it is usually combined with other anti-TB drugs for a synergistic effect.

- Good oral bioavailability for convenient dosing
- Well-tolerated with a manageable side effect profile
