Efficacy and Potency: Efficacy refers to the maximum effect a drug can produce, while potency refers to the amount of drug required to produce a specific intensity of effect. The PK/PD Connection

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). Basic Pharmacokinetics and Pharmacodynamics: An...

Excretion: Finally, the drug and its metabolites are removed from the body. The kidneys are the primary organs for excretion via urine, though drugs can also be cleared through bile, sweat, or breath. Pharmacodynamics: What the Drug Does to the Body Efficacy and Potency: Efficacy refers to the maximum

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. When a drug binds, it can either activate
