Study Notes
Protein targets for drug binding include physiological receptors, enzymes, ion channels, carriers, and structural proteins. Examples of drugs targeting these include sulfonylurea for ion channels, Na+, K+-ATPase inhibitor for carriers, and vincristine for structural proteins. Drug-receptor interaction involves affinity and efficacy, with agonists producing a response and antagonists blocking the actions of agonists. Characteristics of drugs include minimal side effects, no toxicity or harm to normal physiological activities, and being able to apply only where needed. Common side effects of aspirin, antibiotics, and antidepressants include upset stomach, nausea, vomiting, and allergic reactions.
