Relief Timeline for Ranitidine:

Onset of Action: Ranitidine, a histamine H2 receptor antagonist, generally began working within 30 minutes to 1 hour after taking a dose. This is the timeframe it takes for the medication to reach sufficient concentration in your bloodstream and start blocking the action of histamine, a substance that stimulates stomach acid production.

Peak Effect: Ranitidine reached its peak effectiveness within 1-3 hours after ingestion. During this time, you would have experienced the most significant reduction in stomach acid production and the greatest relief from heartburn symptoms.

Duration of Action: A single dose of ranitidine could provide relief for up to 12 hours. This is because the medication binds to histamine receptors for a prolonged period, preventing them from being activated and triggering acid secretion.
