Liver safety of Morphine[edit source]

Mechanism of action of Morphine[edit source]

Morphine is a natural alkaloid that is derived from resin extracts from the seeds of the opium poppy, Papaver somniferum. Morphine has potent and profound analgesic effects and has been used in clinical medicine for almost two hundred years. Morphine acts by engagement in cell surface opiate receptors (predominant µ type receptors) that are found in the central nervous system, but also heart, lung, vascular and intestinal cells. Current indications are for severe pain, pre- and postoperative analgesia, control of pain from angina pectoris or acute myocardial infarction and therapy of pulmonary edema.

Dosage and administration for Morphine[edit source]

Morphine is available in multiple formulations, including oral tablets and syrups, suppositories, and solutions for injection in multiple concentrations. The typical dose of morphine for analgesia in adults is 10 mg every 3 to 4 hours by the subcutaneous, intramuscular or intravenous route. Morphine is well absorbed orally, but has extensive and variable first pass metabolism, so that its effect orally is somewhat variable.

Side effects of Morphine[edit source]

Side effects of opiates are many and include sedation, respiratory depression, confusion, euphoria, agitation, itching, abdominal bloating, nausea, vomiting and diarrhea.

DEA controlled substance classification of Morphine[edit source]
