About H2 blockers. H2 blockers â also known as histamine 2 receptor antagonists â are medications that decrease the amount of acid the stomach produces. These drugs are used to treat various gastrointestinal disorders.2 blockers can slow the time it takes to eliminate certain drugs from the body. Of particular concern to individuals taking H2 blockers are: 1  Bronchodilators (drugs that expand airways in the lungs) such as aminophylline, oxtriphylline or theophylline. 2  Anticoagulants (drugs that help prevent blood clots).
1 Proton pump inhibitors and H2 blockers: Doctors sometimes recommend a nighttime dose of an H2 blocker for people who are taking PPIs twice a day. 2  This is based on the belief that adding the H2 blocker will prevent a rise in acid reflux at night.2 blockers inhibit acid secretion for 6 - 24 hours and are very useful for people who need persistent acid suppression. They may also prevent heartburn episodes. In some studies, H2 blockers improved asthma symptoms in people with both asthma and GERD.
