| are synthesized by chemical procedures in the lab | Synthetic drugs |
| directly produced by bacteria and fungi and then purified and concentrated | Antibiotics |
| antimicrobial drugs must often act within the host without damaging the host | selective toxicity |
| when first developed hailed as "miracle drugs" | antibiotics |
| interferes with bacterial ribosomes and also causes a bacteriostatic effect - mostly effective against gram positives | Erythromycin |
| interferes with protein synthesis and is bacteriostatic; can damage the prokayotic ribosomes in human mitochondria and cause adverse effects on human cells | Chloramphenicol |
| side effect of chloramphenicol | aplastic anemia |
| injury to cytoplasmic membrane causing permeability changes which lead to cell lysis and death - very toxic to kidneys | Amphotericin-B |
| toxic to kidneys | nephrotoxic |
| interferes with viral DNA snthesis - primarily in treating herpes virus infections | Acyclovir |
| used for the treatment of AIDS patients- inhibits the activity of "reverse transcriptase" | Azidothymidine (AZT) |
| inhibit protease enzymes required for intracellular viral maturation | Protease inhibitors |
| atazanavir, indinavir, sequinavir | Protease inhibitors |
| antiviral cytokine | Interferon |
| drug prescribed to treat genital warts | imiquimod |
| synthetic derivative of quinine and is used to treat malaria | Chloroquine |
| used to treat Giardia lamblia and Trichomonas vaginalis- also affective against obligate anaerobic bacteria | Metronidazole (Flagyl) |
| drug similar to metronidazole approved to treat Giardia lamblia, amebiasis, and trichomoniasis | Tinidazole |
