Long-term or high-dose use of opioids may also lead to additional mechanisms of tolerance becoming involved. This includes downregulation of MOR gene expression, so the number of receptors presented on the cell surface is actually reduced, as opposed to the more short-term desensitisation induced by

In some cases, agonists have such low efficacy that they cannot achieve the maximum response that a full agonist does, even when occupying all the receptors present in the tissue (Figure 1B); these agonists are called partial agonists. For example, with MOP receptors, ligands such as buprenorphine,

Substantial tolerance to respiratory depression develops quickly, and tolerant individuals can withstand larger doses. However, tolerance to respiratory depression is quickly lost during withdrawal and may be completely reversed within a week. Many overdoses occur in people who return to their

being the most widely used example. Opioid antagonists work by binding competitively to μ-opioid receptors and displacing opioid agonists. Additional doses of naloxone may be necessary and supportive care should be given to prevent hypoxic brain injury by monitoring vital signs.
