Drugs that stop viruses from multiplying by blocking steps in their life cycle, since viruses use the host's own cells.
Antivirals block a viral step inside host cells: aciclovir (activated in herpes-infected cells, blocks viral DNA); oseltamivir (blocks influenza neuraminidase, so the virus cannot spread); HIV needs combinations (reverse transcriptase, protease); resistance drives combination use.
Antimicrobial Classes
Antibiotics grouped by their mechanism of action.
Antimicrobial Stewardship
Using antibiotics responsibly to preserve their effectiveness.
Antimalarial Drugs
Drugs used against the malaria parasite, which act at different stages of its life cycle inside the red cells and the liver.
Antitubercular Drugs
Drugs that kill the slow-growing tuberculosis bacillus, used together in combinations to prevent resistance.
Cephalosporins
A large family of beta-lactam antibiotics, grouped into generations that broadly shift from Gram-positive cover towards Gram-negative and hospital organisms.
Penicillins and Beta-Lactam Antibiotics
The large family of antibiotics built around the beta-lactam ring, which kill bacteria by wrecking their cell wall.
