Loperamide is used in the treatment of diarrhea. Loperamide is an anti-diarrhoeal medication. It works by slowing down the contraction of the intestines thereby decreasing the speed at which the contents pass through it. This allows more time for reabsorption of fluids and nutrients, making the stools more solid and less frequent.
Metoclopramide is used in the treatment of nausea, vomiting and indigestion. Metoclopramide is a prokinetic. It works on the region in the brain that controls vomiting. It also acts on the upper digestive tract to increase the movement of the stomach and intestines, allowing food to move more easily through the stomach.
Phenylephrine is used in common cold symptoms. It is a decongestant. It works by narrowing the small blood vessels which provides temporary relief from inflammation (redness and swelling) and discomfort.
Paracetamol, also known as acetaminophen and APAP (acetyl-para-aminophenol), is a medication used to treat pain and fever. Paracetamol is generally safe at recommended doses. The recommended maximum daily dose for an adult is 3 (3000 mg) grams. It does not have significant anti-inflammatory activity. Taking more paracetamol could cause damage to your liver.
