17
Q

when should you withhold metformin acutely

A
  • AKI

  • acute alcohol intoxication

sulphonylureas indications

A
  • T2DM
20
Q

MOA sulphonylureas

A
  • stimulate pancreatic insulins ecretion. block ATP dependant k+ channels in pancreatic b cell membranes = depolarisation and open VGCC = increase intracellular ca = secrete insulin

only useful if residual pancreaetic function left

21
Q

SE sulphonylureas

A
  • dose related; GI upset (nausea, vomiting, diarhroea and constipation)
  • hypoglyczemia
  • hypersensitivity reactions, agranulocytosis, haem abnormalities
22

dose reductin in which patients

A
  • hepatic impairment
  • renal impairment

careful in those at increased risk of hypos e.g. hepatic inpairment, malnutrition, adrenal or pituitary insufficiency and elderly

BB
