Morphine

Overview
Morphine is a non-synthetic narcotic with a high potential for abuse and is the principal constituent of Opium. It is one of the most effective drugs known for the relief of severe pain.

Morphine is marketed under generic and brand name products, including MS-Contin®, Oramorph SR®, MSIR®, Roxanol®, Kadian®, and RMS®.

Methods of use
Traditionally, morphine was almost exclusively used by injection, but the variety of pharmaceutical forms that it is marketed as today, including oral solutions, immediate-and sustained-release tablets and capsules, suppositories, and injectable preparations, support its use by oral and other routes of administration. Those dependent on morphine prefer injection because the drug enters the blood stream more quickly.

Effects on the Mind
Morphine's effects include euphoria and relief of pain. Chronic use of morphine results in tolerance and physical and psychological dependence.

Effects on the Body
Morphine use results in relief from physical pain, decrease in hunger, and inhibition of the cough reflex.
