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).

Factors like the route of delivery (oral, intravenous, topical), the drug’s solubility, and the physiological environment (such as stomach pH) influence how much of the drug reaches systemic circulation.
