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).
Histamine encourages acid secretion in the stomach. H2 blockers are available over the counter and relieve symptoms in about half of GERD patients. It takes 30 - 90 minutes for them to work, but the benefits last for hours. People usually take the drugs at bedtime.Some people may need to take them twice a day.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.
