Morphine sulfate is a very potent narcotic analgesic used to relieve severe pain such as that produced by myocardial infarction, passage or renal calculi, or terminal conditions.
Morphine is almost effective when given before the client experiences severe pain. Morphine’s analgesic effect allows the client to rest more comfortably.
It is the interaction of morphine with the ongoing biological processes of the body that is responsible for its ability to producer effects like pain relief and/or addiction.
Specially, morphine produces its effect by altering the functioning of neurons. Morphine interacts with the so-called opioid receptors in the brain. Receptors are complex molecules of high relative molecular mass that are composed of condensed amino acid. They recognized particular substrates (in this case morphine) and on binding to the small partner, the receptor acts to release a signal that can elicit a physiological effect.
Opiates are sometimes called ‘narcotics’ because in high doses they can produce a dazed state of ‘narcosis’ or dream-like state, resulting from massive reductions on the activity of the nervous system.
