What does antitubercular mean?
Antitubercular describes anything that acts against tuberculosis, the infectious bacterial disease caused by Mycobacterium tuberculosis. Most often used as an adjective, it applies to drugs such as isoniazid, rifampicin, and streptomycin that kill the bacterium or halt its growth; less commonly it functions as a noun naming such a drug itself. The word belongs chiefly to medical and pharmacological registers, appearing in clinical guidelines, research papers, and public-health discussions rather than casual conversation. Its roots lie in Latin: 'anti-' meaning against, combined with 'tuberculum', a small swelling or nodule — the name given to the lesions the disease produces in the lungs. Because completing antitubercular treatment correctly is central to preventing drug-resistant strains of tuberculosis, the term carries real public-health significance. A closely related variant, antituberculous, is common in British medical texts.
Acting against tuberculosis; used in the prevention or treatment of tuberculosis.
"The clinic stocked a full range of antitubercular medications."
Standard term in pharmacology and clinical medicine; 'antituberculous' is a common variant.
A drug or agent that is effective against tuberculosis.
"Rifampicin is among the most widely prescribed antituberculars."
Used when referring to multiple antitubercular drugs collectively.
"Resistance can emerge when patients take several antituberculars irregularly."
The word literally means 'against the little swelling' — because tuberculosis was named after the tiny tubercles, or nodules, it forms in the lungs.

Etymology of antitubercular
Antitubercular combines the Greek-derived prefix 'anti-' (against) with 'tubercular', which traces to the Latin 'tuberculum', a diminutive of 'tuber' meaning a swelling or lump. Physicians adopted 'tubercle' to describe the nodular lesions characteristic of tuberculosis, giving the disease its name in the early nineteenth century. The word thus shares its origin with cognates such as tubercle, tuberculin, and tuberous.
