Sural

Sural is an antibacterial prescription medicine containing ethambutol hydrochloride. It is classified as an antituberculosis agent that works by inhibiting the synthesis of cell wall metabolites in actively growing tubercle bacilli, thereby halting their growth. Sural must always be used in combination with other anti-TB medications to prevent the development of drug resistance.
