Rifampicin + Isoniazid (Duomax) 150mg/75mg Film-Coated Tablets (80's) is a combination antibiotic used primarily in the treatment of tuberculosis (TB). Rifampicin (150mg) and Isoniazid (75mg) work together to kill the bacteria responsible for TB. Rifampicin inhibits bacterial RNA synthesis, while Isoniazid interferes with the synthesis of bacterial cell walls. This combination therapy helps prevent the development of drug-resistant TB strains and is typically prescribed for the initial intensive phase of TB treatment. The 80 tablets in the package provide a complete course of treatment when taken as directed.
