Endocrinology Flashcards
Drug Class: insulin
peptide hormone
Insulin - how does it work?
stimulates glucose uptake, metabolism, absorption by skeletal muscle. Drives K into cells
Indications: insulin
type 1 diabetes, type II diabetes, hyperkalaemia, diabetic ketoacidosis
Contra-indications: insulin
renal impairment, hypoglycaemia
Side effects: insulin
hypoglycaemia, fat overgrowth, weight gain, hypersensitivity
Interactions: insulin
corticosteroids, B-blockers (mask warning signs of hypoglycaemia)
Drug class: gliclazide
Sulphonylureas
Gliclazide - how does it work?
stimulates pancreatic insulin secretion, block K channels, increases Ca in pancreatic B cells
Indications: gliclazide
type II diabetes, reduce metformin complications
Contra-indications: gliclazide
hepatic/renal/adrenal/pituitary insufficiency, malnutrition, elderly
Side effects: gliclazide
hypoglycaemia, fat overgrowth
Interactions: gliclazide
thiazide diuretics, metformin, insulin, prednisolone
Drug class: metformin
Biguanide
How does it work - metformin
increases insulin sensitivity, suppresses glucose production, reduces weight gain
Indications: metformin
type II diabetes
Contra-indications: metformin
renal/hepatic impairment, AKI, severe tissue hypoxia
Side effects: metformin
GI issues, lactic acidosis, hypoglcaemia
Interactions: metformin
alcohol, prednisolone
Example - thyroid hormones
thyroxine, liothyronine
