Message definition (Metformin)
=== Interactions ===
The [[H2 antagonist|H<sub>2</sub>-receptor antagonist]] [[cimetidine]] causes an increase in the plasma concentration of metformin by reducing [[clearance (medicine)|clearance]] of metformin by the kidneys; both metformin and cimetidine are cleared from the body by [[Renal physiology#Secretion|tubular secretion]], and both, particularly the [[cation]]ic (positively [[electric charge|charged]]) form of cimetidine, may compete for the same transport mechanism. A small [[blind experiment|double-blind]], randomized study found the [[antibiotic]] [[cephalexin]] to also increase metformin concentrations by a similar mechanism; theoretically, other cationic medications may produce the same effect.

Interactions

The H2-receptor antagonist cimetidine causes an increase in the plasma concentration of metformin by reducing clearance of metformin by the kidneys; both metformin and cimetidine are cleared from the body by tubular secretion, and both, particularly the cationic (positively charged) form of cimetidine, may compete for the same transport mechanism. A small double-blind, randomized study found the antibiotic cephalexin to also increase metformin concentrations by a similar mechanism; theoretically, other cationic medications may produce the same effect.
