Preview

Opioids act through μ, κ, and δ G-protein coupled receptors. The opioid peptides and receptors form an endogenous analgesic system. Opioid analgesics exert their therapeutic action through μ-receptors. Most of the opioid adverse effects are due to μ-receptor activation. The rational choice of opioids is governed by their pharmacokinetic profiles and patient’s individual responses to agents. Morphine remains a good starting point to assess the opioid sensitivity of a pain condition.
