Morphine Standard of comparison of all opioid analgesicsModerate analgesic potencySlow onset to peak effectIntermediate duration of activityDose dependent adverse effectsRelease of histamine which may precipitate hypotension and bronchospasmIncreases smooth muscle tone which exacerbate biliary, tubular, and ureteralcolicOxycodone Semisynthetic mu receptor agonistHigh oral bioavailabilityLess sedation than equivalent doses of morphineHydromorphone Semysinthetic mu selective opioid agonistAnalgesic potency 5-6 times greater than morphine with a greater ability topenetrate the blood brain barrierLess histamine releaseFentanyl Mu-specific opioid agonist related to meperidineAnalgesic potency 35-60 times greater than morphineRapid onset and variable dose-dependent duration of effectRapidly penetrate blood brain barrier and bind opioid receptors in centralnervous systemProvide hemodynamic stabilityMajor adverse effects include rapid and profound respiratory depressionand chest wall rigidityMethadone Opioid agonistAnalgesic potency 1.5-2 times greater than morphineOral bioavailability greater than 80%Accumulates in tissues so analgesic duration and risk of overdosing mayincrease with dosesProlongation of QTc interval and may initiate or exacerbate torsades depointes and Wolff-Parkinson-White syndromeGood choice for patients with highly opioid dependent disordersMeperidine Opioid agonistAnalgesic potency one tenth that of morphineProduces smooth muscle relaxing effectCodeine Opiate-derived analgesicAnalgesic potency one-third to one-fourth as potent as morphineHigh incidence of nausea and vomitingTramadol Weak mu-receptor opioid agonistAlso inhibits re-uptake of both 5-HT and noradrenaline and stimulates thepresynaptic release of 5-HTAnalgesic potency similar to codeineNot recommended for severe acute painSufentanil Synthetic mu-specific opioid agonist related to fentanylAnalgesic potency 500-700 times greater than morphineRapid onset and dose dependent duration of effectBuprenorphine Partial agonist-type opioidAvailable in a sublingual formulation
