A single 10 mg dose administered intravenously produces an average initial serum concentration of 60 ng/mL which declines rapidly then levels off to a concentration of 3 ng/mL for up to 36 hours. An equivalent dose administered intramuscularly produces similar results, 70 ng/mL at 10 to 20 minutes and 20 ng/mL in 4 hours. The metabolite morphine -3-glucuronide appeared in serum within 20 minutes of administration and exceeded morphine concentrations after 2 hours. The plasma half-life of morphine in surgical patients averaged 1.08 hours in women and 2.9 hours in men.
URINE EXCRETION RATE: Up to 87% of a dose of morphine is eliminated in the 72 hour urine. Morphine glucuronide makes up 75% of the eliminated dose. Free morphine accounts for approximately 10% of the dose. Codeine that shows up in the urine following morphine administration is a result of the impurity of commercial morphine (0.04%).
