Pharm1 Flashcards
Drug Sources
- Traditional – Plant (botanical): alkaloids = “ine” (e.g. atropine, caffeine, nicotine) or glycosides =“in” (e.g. digoxin), gums, resins, oils – Minerals (e.g. Na, K, Cl, Fe, Se)
- Bacteria/Fungi = antibiotics (penicillin) and anthelmintics (ivermectin)
- Animals – hormones (insulin), anticoagulants (heparin); most are now synthesized in laboratories
- Genetic engineering
