Final answer:
Isoniazid is a drug used in the treatment of tuberculosis. It specifically targets mycobacteria by preventing the synthesis of mycolic acid, necessary for their cell walls. Side effects may occur.
Step-by-step explanation:
Isoniazid is a drug commonly used in the treatment of tuberculosis (TB). It is an antimetabolite that specifically targets mycobacteria, the bacteria that cause TB. Isoniazid is administered in combination with other drugs like rifampin or streptomycin to effectively treat the infection.
The drug works by preventing the synthesis of mycolic acid, which is crucial for the formation of mycobacterial cell walls. This ultimately hinders the growth and survival of the bacteria.
It's important to note that the use of isoniazid may have side effects, such as hepatotoxicity, neurotoxicity, and hematologic toxicity. Therefore, it should be used under the guidance of a healthcare professional.
