Prevacid (Lansoprazole): MEDICINE INFORMATION
Therapeutic Class: Antacid/Heartburn: Prevacid (Lansoprazole)
Active Ingredient: The active constituent present in Prevacid is Lansoprazole.
Drug Information: Prevacid is the brand name for medication, Lansoprazole. It is indicated in the treatment of certain stomach and esophagus problems (like acid reflux, ulcers).
Mechanism of action:
Like any other proton pump inhibitor, Lansoprazole exerts its action by blocking an enzyme named as H+/K+ ATPase, in the acid-secreting cells that form lining of the stomach. The major task of this enzyme is to produce acid. As a rule, this is good as it permits us to have food in a proper manner. On the other hand, in the case of an ulcer or GERD, production of acid in normal way can be harmful. Lansoprazole gets activated by the high acidity in the stomach, and binds itself to the enzyme, which prevents it from functioning for a short while.
How to use Prevacid?
Prevacid is available in 15mg and 30mg doses. It must be taken twice on a daily basis, prior to your meals. Since it’s a tablet dosage form, it’s a good idea to take it with glass full of water. Never crush or chew the medicine.
What happens in case of missed dose?
If you miss a dose of Lansoprazole, take it as soon as possible. Don’t take two at once to compensate for a missed dose.

Drug interactions may modify the working of your medicines and may augment your risk for severe side effects. Avoid initiating, stopping or modifying the dosage of any medications without your doctor's approval. Some medicines require stomach acid in order that the body can absorb them in a proper way. Lansoprazole is known to reduce the stomach acid, so it may alter how well these products work. Few affected medications may involve penicillins, anti-virals, anti-cancer medicine such as erlotinib, and certain azole antifungals, among others. Lansoprazole looks comparable to Dexlansoprazole in action. Thus avoid the use of drugs containing dexlansoprazole while making use of Lansoprazole.
