    Area of Science:

    • Gastroenterology
    • Pharmacology

    Background:

    • Peptic ulcers, including gastric and duodenal ulcers, represent a significant gastrointestinal condition.
    • Effective pharmacological interventions are crucial for managing ulcer healing and patient outcomes.

    Purpose of the Study:

    • To evaluate the efficacy and safety of ranitidine in treating patients diagnosed with gastric and duodenal ulcers.
    • To determine the healing rates and time course of ulcer resolution with ranitidine therapy.

    Main Methods:

    • A clinical study involving 24 patients with gastric ulcers and 18 with duodenal ulcers.
    • Patients received ranitidine 300 mg daily for up to 8 weeks, with endoscopic assessment for healing.
    • Comparison was made against placebo to assess statistical significance.

    Main Results:

    • Ranitidine demonstrated a statistically significant therapeutic effect compared to placebo.
    • For gastric ulcers, 50% healed within 4 weeks and 83% within 8 weeks.
    • For duodenal ulcers, 50% healed within 2 weeks and 94% within 4 weeks.

    Conclusions:

    • Ranitidine is an effective treatment for both gastric and duodenal ulcers.
    • The medication shows a favorable safety profile with few reported side effects.
    • Rapid healing rates observed suggest ranitidine's clinical utility in peptic ulcer disease management.
