Adverse Drug Reactions
Diarrhoea, vomiting, metallic taste, rash, isolated transaminase elevations, cholestatic jaundice, allergic skin reactions, photosensitivity reactions, leukopaenia, agranulocytosis, thrombocytopaenia, haemolytic anaemia, aplastic anaemia, pancytopaenia, blurred vision. Potentially Fatal: Lactic acidosis.
Concomitant admin with propranolol increases Cmax, AUC, and T1/2 of glimepiride. Aspirin increases the mean AUC of glimepiride. Furosemide increases the Cmax of metformin. Potentially Fatal: NSAIDS, salicylates, sulfonamides, chloramphenicol, coumarins, probenecid, MAOs, and beta blockers potentiate the hypoglycemic action of glimepiride.
Mechanism of Action
Glimepiride stimulates the insulin release from functioning pancreatic β-cells and inhibits gluconeogenesis at hepatic cells. It also increases insulin sensitivity at peripheral target sites. Metformin decreases hepatic gluconeogenesis, decreases intestinal absorption of glucose and improves insulin sensitivity (increases peripheral glucose uptake and utilisation).
