Before going any further, it is necessary to enlarge upon the term and define what tolerance means. Drug tolerance can be generally defined as . There are several hypotheses about how tolerance develops, including opioid receptor phosphorylation (which would change the receptor conformation), functional decoupling of receptors from G-proteins (leading to receptor desensitization),[2] mu-opioid receptor internalization and/or receptor down-regulation (reducing the number of available receptors for morphine to act on), and upregulation of the cAMP pathway (a counterregulatory mechanism to opioid effects) (For a review of these processes, see Koch and Hollt. It should be pointed out that the term tolerance is frequently employed improperly and thus generates as much confusion as it does clarity.
