Summary
Alkalinizing agents may increase the dissolution and absorption of sulfonylureas, and urinary alkalinization can alter renal elimination of weakly acidic drugs. The clinical effect on gliclazide is small and inconsistent, but a modest rise in glucose-lowering effect is conceivable.
What this interaction means in plain words
Gliclazide and Sodium bicarbonate have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Gliclazide belongs to Endocrine; Sodium bicarbonate belongs to Gastrointestinal Tract.
Why it happens
Higher gastric and urinary pH may modestly alter sulfonylurea absorption and renal clearance.
What to do
No routine change is needed; check blood glucose if sodium bicarbonate is used regularly or in large doses with gliclazide.
