WHY Omeprazole commotion Remain For 2 TO 3 Houres While Half Life 1 Houre?

WHY Omeprazole commotion Remain For 2 TO 3 Houres While Half Life 1 Houre?
I Looked this Up, it Binds IRREVERSIBLY to Parietal K+/H+ Pumps In the Stomach, this Accounts for the Discrepancy In SERUM Half-Life.
The half life span of Omeprazole (Prilosec) is about one hour, objective that after one hour your body has partially of the dosage at steady state. The actual dosage needed to have effects may be moderately lower than the average concentration (e.g. 10 mg = 5 mg after one hour = 2.5mg after 2 hours = 1.25mg after 3 hours, etc.) If the amount remaining is enough to still wreak effects, so it will be.
If you want specifics:
In addition, after oral supervision, the onset of the antisecretory effect of omeprazole occur within one hour. Inhibition of secretion is almost 50% of maximum at 24 hours and the duration of inhibition lasts up to 72 hours. The antisecretory effect thus last far longer than would be expected from the very short (less than one hour) plasma half-life, apparently due to prolonged binding to the parietal H+/K+ ATPase enzyme.
