What do H2 blocker medications primarily treat?

Explanation:
H2 blockers work by blocking histamine H2 receptors on the stomach’s parietal cells, which reduces stomach acid production. Because excess acid drives symptoms of acid reflux and GERD, these drugs are used to treat acid reflux and related ulcer/gastritis problems. They don’t address allergic eye symptoms (that would be H1 antihistamines), prostate enlargement (BPH), or Parkinson’s disease (dopaminergic therapy). In short, they relieve symptoms caused by too much gastric acid.
