The market is primarily driven by the increasing prevalence of acid reflux diseases and peptic ulcers. H2 receptor antagonists are commonly used for short-term treatment of these conditions and see significant demand. The H2 receptor antagonist market is expected to witness steady growth over the forecast period. While several drugs in this category have lost patent exclusivity, resulting in generic competition, there remains a large patient pool being treated for acid reflux diseases. Additionally, the market is anticipated to benefit from the approvals and launches of novel drug delivery formulations such as orally disintegrating tablets. However, the market growth could be hindered by the loss of patients shifting to cheaper generic drugs as well as increasing adoption of proton pump inhibitors, which are often preferred by physicians and patients for long-term acid reflux management.

The Prevalence of Gastroesophageal Reflux Disease

Gastroesophageal reflux disease (GERD) has been on the rise over the past few decades across many countries. It is commonly known as acid reflux or heartburn. GERD occurs when stomach acid flows back up into the esophagus. This backwash (reflux) causes irritation in the esophagus, resulting in symptoms like a burning sensation in the chest and throat, regurgitation of food and sour liquid, difficulty swallowing, coughing, and wheezing. GERD can negatively impact quality of life and lead to complications if left untreated for a long period of time. The exact causes of GERD are not fully known, but there are several contributing factors. Increasing rates of obesity have likely played a major role. Excess abdominal fat is known to increase pressure on the stomach, hindering its ability to keep acid contained. Rising levels of stress, poor eating habits like overeating, eating late at night, and consumption of acidic, spicy or fatty foods can also trigger acid reflux symptoms. With today's busy lifestyles, people also tend to skip meals more often or grab fast food on the go. Advancement in medical diagnostics has enabled doctors to identify GERD more accurately as well. 

Preference for Long-Term Proton Pump Inhibitor Therapy Alternatives

Proton pump inhibitors (PPIs) have been the standard initial treatment for GERD and acid reflux disease management. However, frequent and long-term PPI usage can have certain side effects and risks that patients want to avoid if possible. PPIs work by reducing acid production over a longer duration compared to H2 receptor antagonists. While PPIs provide strong acid suppression and are effective against chronic and more severe GERD cases, extended usage.
