Diabetic Drugs Flashcards
Example of Biguanide
Metformin
Mechanism of action of Metformin
Increase insulin sensitivity in the skeletal muscle and adipose, Decrease hepatic gluconeogenesis
ADRs of metformin
Nausea, Vomiting, Lactic acidosis, B12 deficiency
Examples of thiazonlidinediones (glitazones)
Piaglitozone, Rosiglitazone
Mechanism of action of thiazonlidinediones (glitazones)
Activate PPAR gamma receptors reducing gluconeogenesis and increasing glucose uptake
ADRs of thiazonlidinediones (glitazones)
Weight gain, Heart failure, Oedema
DDIs of thiazonlidinediones (glitazones)
Displacement from plasma proteins
Half-life of thiazonlidinediones (glitazones)
7hrs, metabolites active for 150hrs
Examples of sulphonylureas
Tolbutamide, Glibenclamide
Mechanism of action of sulphonylureas
Antagonise the ATP dependent K channels on beta cells, cause depolarisation opening VOCC causing insulin release
ADRs of sulphonylureas
Nausea, Weight gain, Vomiting, Hypoglycaemia
DDIs of sulphonylureas
Displacement from plasma proteins
Mechanism of action of gliptins
Mimic GLP1 - increase insulin secretion, decrease glucagon secretion, decrease gluconeogenesis, increase glucose uptake by muscles
ADRs of gliptins
GI upset
Mechanism of action of alpha glucosidase inhibitors
Inhibit alpha glucosidase preventing the breakdown of dietary carbohydrates to glucose
