Summary
Sodium bicarbonate raises gastric and urinary pH, which can accelerate absorption of glipizide and slightly increase its effect. Hypoglycemia is possible but usually modest.
What this interaction means in plain words
Glipizide-metformin 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.
Glipizide-metformin belongs to Endocrine; Sodium bicarbonate belongs to Gastrointestinal Tract.
Why it happens
Increased gastric pH alters dissolution and absorption of glipizide, and alkaline urine may reduce sulfonylurea renal elimination.
What to do
Monitor blood glucose when antacid use is frequent or high dose, and adjust glipizide if hypoglycemia occurs.
