• Anticancer — Combating, preventing, or destroying malignant tumor cells; an oncological substance, cellular therapy, or cytostatic medication specially designed to halt neoplasm proliferation within the human organism. In a modern clinical sense, the term covers classic chemotherapy molecules as well as advanced immunotherapy protocols and molecularly targeted therapies.
• Anti-coronavirus — Combating, neutralizing, preventing, or halting the multiplication and spread of viruses from the Coronaviridae family (including SARS-CoV-2); an antiviral medication, monoclonal antibody, immunological vaccine, or surface disinfectant specifically formulated to destroy or inhibit the viral structure in the organism or the environment.
• Antifebrile — Combating, reducing, or preventing fever (the pathological increase in body temperature); a medicinal substance or natural remedy with antipyretic action. Antifebrile drugs act on the hypothalamus to reset the thermal autoregulation center affected by pyrogens.
• Antineuralgic — A property of a substance or medication to combat, alleviate, or suppress violent pain localized along the path of a nerve; in a noun sense, it represents a complex analgesic and antipyretic pharmaceutical preparation, widely used for the rapid relief of headaches, dental or intercostal neuralgias, and mild febrile states.
• Antiparkinsonian — Combating, ameliorating, or controlling the symptoms of Parkinson's disease and extrapyramidal syndromes; a drug or therapeutic agent structurally designed to restore the balance of neurotransmitters in the brain, specifically by increasing dopamine levels or blocking the effects of acetylcholine.

• Antituberculosis — Preventing, combating, curing, or acting directly against tuberculosis; a specific antibiotic or chemotherapeutic agent (such as isoniazid, rifampicin, or pyrazinamide) used to destroy or halt the replication of the Mycobacterium tuberculosis bacterium (Koch's bacillus) in the body.
• Antitumor — Preventing, combating, inhibiting, or destroying the development and proliferation of tumors, especially malignant ones; a medication, chemotherapeutic agent, or biological agent used in cancer therapy. These compounds act by blocking abnormal cell division, inducing apoptosis in cancer cells, or halting the angiogenesis necessary for the tumor's nutrition.
• Antiviral — Destroying viruses or halting their replication inside host cells; a medication or biological agent (such as acyclovir or oseltamivir) used in the treatment of viral infectious diseases. These compounds act by blocking viral membrane attachment, inhibiting genetic material replication, or preventing the release of new virions.
• Anxiolytic — Diminishing, calming, or suppressing a state of anxiety and mental tension; (noun) a medicinal substance or pharmaceutical preparation used in the treatment of anxiety disorders, acting on the central nervous system to restore emotional balance.
• Atabrine — A historic commercial name for quinacrine (mepacrine), a synthetic acridine-derived drug widely utilized during the mid-20th century as a major antimalarial and antiprotozoal agent.
