Agonists. Agonists bind to and activate receptors in a dose-dependent manner until all opioid receptors are occupied. At this point, the response plateau is reached, and increased doses of agonist have no effect. However, continued use beyond this plateau may lead to respiratory depression and overdose.ntagonists.
