WebDec 16, 2024 · Partial agonist shows intrinsic activity greater than 0 but less than 1. For example, Buprenorphine is a partial agonist at the μ receptor. In other words, an … WebReceptors are responsible for selectivity of drug action. The molecular size, shape, and electrical charge of a drug determine whether—and with what affinity—it will bind to a particular receptor among the vast array of chemically different binding sites available in a cell, tissue, or patient.

WebOpioid drugs include full agonists, partial agonists, and antagonists–measures of intrinsic activity or efficacy. Morphine is a full agonist at the μ (mu)-opioid receptor, the major analgesic opioid receptor (Table 31–1). Opioids may also differ in receptor binding affinity.
