What is Prevacid?

Prevacid is an antiulcer product, proton pump inhibitor. The drug contains Lansoprazole. This ingredient interacts with the cells of stomach where a secretion of hydrochloric acid is produced. A final stage of the synthesis of hydrochloric acid is blocked within 6-12 hours.

A therapeutic effect grows within 4 days. A basal and stimulated secretion of hydrochloric acid is gradually reduced regardless of the type of the irritation of the receptors. The use of Prevacid in therapeutic doses within 5-7 days, a synthesis of acid drops by 80-95%. The gastric motor activity is not affected during such significant reduction of the secretion of the gastric acid. Even a long-term use of the capsules does not slow the intestinal motility, does not cause a digestion disorder and other side effects.

A secretory activity is completely restored within a week after the end of the therapy.
