Morphine is one of the most important and widely used opioid for the treatment of chronic and acute pain: the very wide interindividual variability in the patients’ response to the drug may have genetic derivations. Sulphate salt of morphine sold under the many brand names, one of them, DURAMORPH, which is indicated for the management of pain severe enough to require use of an opioid analgesic by intravenous administration, and for which alternative treatments are not expected to be adequate. In addition for the epidural or intrathecal management of pain without attendant loss of motor, sensory, or sympathetic function. Morphine is a full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of morphine is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with morphine. The precise mechanism of the analgesic action is unknown. However, specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and are thought to play a role in the analgesic effects of this drug. Morphine has a high potential for addiction and abuse. Common side effects include drowsiness, vomiting, and constipation. Caution is advised when used during pregnancy or breast-feeding, as morphine will affect the baby.

Sample Use Guides

In Vivo Use Guide

Dosage for Intravenous Administration: Adult Dosage: The initial dose of morphine should be 2 mg to 10 mg/70 kg of body weight. Dosage for Epidural Administration: Adult Dosage: Initial injection of 5 mg in the lumbar region may provide satisfactory pain relief for up to 24 hours. If adequate pain relief is not achieved within one hour, careful administration of incremental doses of 1 to 2 mg at intervals sufficient to assess effectiveness may be given. Do not administer more than 10 mg per 24 hours. Dosage for Intrathecal Administration: Adult Dosage: Intrathecal dosage is usually 1/10 that of epidural dosage. A single injection of 0.2 to 1 mg may provide satisfactory pain relief for up to 24 hours. (Caution: this is only 0.4 to 2 mL of the 5 mg/10 mL ampul or 0.2 to 1 mL of the 10 mg/10 mL ampul of DURAMORPH). Do not inject intrathecally more than 2 mL of the 5 mg/10 mL ampul or 1 mL of the 10 mg/10 mLampul. Repeated intrathecal injections of DURAMORPH are not recommended. If pain recurs, consider consider alternative routes of administration.

In Vitro Use Guide

It was evaluated the effect of morphine on the proangiogenic interaction taking place between macrophages and breast cancer cells in vitro. It was shown, that morphine prevents, in part via modulating VEGF-A expression, the pro-angiogenic interaction between macrophages and breast cancer cells. The conditioned medium (CM) from breast cancer cells co-cultured with macrophages elicited endothelial cell proliferation and tube formation. This effect was inhibited if the co-culture occurred in the presence of morphine (20 uM). Using a mouse antibody array, it was identified several angiogenesis-regulating factors differentially expressed in the CM of co-cultured cells prepared in the presence or absence of morphine (o, 10, 20 uM), amongst which interleukin (IL)-6, tumour necrosis factor (TNF)-α and vascular endothelial growth factor (VEGF)-A. VEGF was induced in both cell types by the co-culture and this was prevented by morphine in a non-naloxone reversible fashion. The effect of CM from co-cultured cells on endothelial tube formation, but not proliferation, was prevented by anti-VEGF neutralizing antibody
