Famotidine is a potent medication used to treat conditions related to excess stomach acid. Its LD50 value is a critical parameter that determines the lethal dose in preclinical studies. Famotidine LD50 indicates the dosage at which 50% of the test subjects would succumb to the compound. This information is crucial for determining the safety and efficacy of the drug in therapeutic applications. Consult your healthcare provider for more information on famotidine and its LD50 value.


Famotidine is a medication that belongs to a class of drugs called H2 blockers. It is commonly used to treat conditions such as heartburn, acid indigestion, and stomach ulcers. Some of the main benefits of famotidine include:

  • Reducing stomach acid production: Famotidine works by blocking the action of histamine, a chemical that stimulates acid production in the stomach. By reducing the amount of acid produced, famotidine can help relieve symptoms of heartburn and indigestion.
  • Healing and preventing ulcer formation: Famotidine can help promote healing of stomach ulcers and prevent them from recurring by reducing acid levels in the stomach.
  • Relief from GERD symptoms: Famotidine is often prescribed to patients with gastroesophageal reflux disease (GERD) to help manage symptoms such as heartburn, acid regurgitation, and chest pain.
  • Improving quality of life: By alleviating symptoms of acid-related conditions, famotidine can improve overall quality of life for patients and allow them to lead a more comfortable and symptom-free lifestyle.



Famotidine is generally safe for most people when taken as directed. However, it is important to follow the dosage instructions provided by your healthcare provider or as indicated on the product packaging.
