Effects of codeine
Codeine phosphate tablets

Codeine phosphate can reduce the muscular activity in the gut and so may oppose the effect of the following medicines on the gut:

In treating diarrhoea, codeine works by acting on opioid receptors that are found in the muscles lining the walls of the intestines. This reduces the muscular contractions of the intestine (called peristalsis) that move food and faecal matter through the gut. The speed at which the gut contents are pushed through the intestines is therefore reduced, allowing more time for water and electrolytes to be reabsorbed from the gut contents back into the body. This results in firmer stools that are passed less frequently.

It is important to l your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you start treatment with this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to make sure that the combination is safe.

In treating cough, codeine works by reducing the nerve signals sent from a part of the brain called the coughing centre to the muscles that produce coughing. Coughing is a reflex response to irritation of the airways. It is useful for clearing mucus, dust and other particles from the throat and lungs. It is important because it reduces the amount of mucus, dust and bacteria in the airways that would otherwise make breathing difficult. However, sometimes, coughing can become overstimulated even when there is no mucus to clear from the lungs or throat. In this situation coughing serves no purpose and can become painful and frustrating. Codeine phosphate can be used to block the cough reflex in situations where the cough serves no purpose, ie when no plegm is being coughed up.

In treating pain, codeine works by mimicking the action of naturally occurring pain-reducing chemicals called endorphins. Endorphins are found in the brain and spinal cord and reduce pain by combining with opioid receptors. Codeine mimicks the action of natural endorphins by combining with the opioid receptors in the brain and spinal cord. This blocks the transmission of pain signals sent by the nerves to the brain. Therefore, even though the cause of the pain may remain, less pain is actually felt.
