content_paste Pharmacological and clinical effects

Peppermint oil has antispasmodic (anti-cramp-ing) effect on the smooth muscles of the gastrointestinal tract and bile ducts. In the irritable bowel syndrome, it slows peristaltic movement which appears to be result of its effects on calcium and potassium channels of the gastrointestinal tract's smooth muscles. 

Peppermint oil also reduce bloating and abdominal pain by facilitating  the excretion of bowel gases which has a combined mechanism including anti-foam effect. In addition, in a study peppermint oil increased bile secretion by 33% and reduced bilirubin concentrations by 63% Since peppermint oil is rapidly absorbed in the proximal intestine, it has some effects on upper gastrointestinal tract such as relaxation of the lower esophageal sphincter. For peppermint oil to exert effects on the lower intestine, it must pass through the upper gastrointestinal tract unmetabolized, so the enteric capsules are suitable for this problem.

content_paste Side Effects

This product is safe when used orally at the recommended dos and no cases of poisoninf are reported.

Peppermint oil can cause heartburn, nausea and vomiting, anal or perianal burning, and rarely allergic reactions and hypersensitivity (due to menthol) including erythematosus skin reactions, flushing, headache, bradycardia (decreased heart rate), muscle tremor and inconsistency in muscle movement (Ataxia).

Because of enteric capsules, less heartburn happens.

content_paste Interaction

Antacids, H2 blockers, and proton pump inhabitors: Since they raise gastric pH, they can cuase enteric capsules to dissolve sooner so separate administration times by at least 2 hours.

Metabolism of cyclosporine and a series of drugs metabolized by the P450 cytochromes (including Amitriptyline, Haloperidol, Ondansetron, Propranolol, Theophylline, Verapamil, proton pump inhabitors, Diazepam, non-steroidal anti-inflammatory drugs (NSAIDs), Warfarin, Losartan, Lovastatin, Ketoconazole, Itraconazole and Fexofenadine) may be inhibited by peppermint oil, so far this interaction has not been reported in humans.
