Indications
Loperamide + Simethicone is used to treat the symptoms of acute diarrhea in adults and adolescents over 12 years, when the diarrhea comes with gas-related discomfort in the abdomen such as bloating, cramping or flatulence.
⚠️ Always consult a registered physician before taking any medicine.
Pharmacology
Loperamide binds to the opiate receptor in the gut wall. This reduces propulsive peristalsis, so food and fluid move through the intestine more slowly, and more water and electrolytes are taken back into the body. Loperamide also increases the tone of the anal sphincter. Simethicone is a surface-active agent with anti-foaming properties, so it may relieve gas-related symptoms that come with diarrhea.
Most of the Loperamide that is swallowed is absorbed from the gut. But because of significant first pass metabolism, systemic bioavailability is approximately 0.3%. Simethicone is not absorbed.
Plasma protein binding of Loperamide is 95%. The liver extracts almost all of it, where it is mainly metabolized, conjugated and excreted through the bile. Loperamide has a half-life of about 11 hours. Unchanged Loperamide and its metabolites leave the body mainly in the faeces.
Pregnancy & Breastfeeding
Nobody has established that Loperamide with Simethicone is safe in human pregnancy. Animal studies show no signs of teratogenic or embryotoxic effects. Even so, it shouldn't be given during pregnancy, especially in the first trimester, unless there is a clinical reason for it.
Small amounts of Loperamide may pass into human breast milk. For that reason, this medicine is not recommended during breast feeding.
⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
