Drugs for infections
Drugs used for infections include antibacterials, antifungals, antivirals, antimycobacterials and antiparasitic drugs.
Antibacterials which act to kill or inhibit the growth of bacteria, target essential bacterial molecular pathways not shared with the host (e.g. inhibiting nucleic acid precursor synthesis, protein synthesis, and cell membrane integrity). Antifungal drugs utilize similar mechanisms, targeting fungal cell wall-synthesizing enzymes for example. The machinery of viral replication are targets for antiviral drugs including HIV, and drugs used in treating mycobacterial infections represent another spectrum of action of drugs for infections.
