Receptors and Targets: Most drugs work by binding to specific receptors—proteins on or within cells. This interaction is often compared to a lock and key. When a drug binds, it can either activate the receptor (agonist) or block it (antagonist).

Distribution: Once in the blood, the drug is carried to various tissues and organs. Distribution depends on blood flow, the drug’s ability to cross cell membranes (like the blood-brain barrier), and its tendency to bind to plasma proteins. Basic Pharmacokinetics and Pharmacodynamics: An...
