Review

Lansoprazole is a chemical compound, a benzimidazole sulphoxide derivative is a member of the pyridines and benzimidazoles.

It occurs as a fine, white powder.

What it is used for and where

Take only under medical supervision

It is one of the proton pump inhibitors (omeprazole, pantoprazole, esomeprazole, rabeprazole and ilaprazole) as a potent inhibitor of gastric acid secretion and is widely used for the treatment of gastroesophageal reflux, dyspepsia and peptic ulcer (1).

It's one of the well tolerated drugs and since it has a certain sensitivity to acids, it is normally administered in the form of capsules containing granules coated with enteric substances to prevent gastric decomposition and to increase bioavailability.

Due to its anti-inflammatory properties, it inhibits the induction of various inflammatory mediators, thus preventing acute liver damage (2).

Lansoprazole supplementation (50 mg/kgBW) for 4 weeks produced significant decreases in the renal cyst  and an improvement in renal function through the reduction of plasma creatinine and blood urea nitrogen (3).

Like all drugs it can cause side effects. Always consult your doctor.
