Inclusion criteria

•Adult patients aged 21 - 80 years old inclusive,
•Able to provide consent,
•Score 3 or less on the Modified Rankin Score (mRS),
•Patients with TIA or mild stroke with severe stenosis of intracranial ICA or MCA and impaired CVR within previous 3-months of acute stroke or TIA

Exclusion criteria

•Chronic kidney disease stage 5 (eGFR<15 mL/min) or on dialysis,
•Cancer diagnosed within past 3 years,
•Currently being planned for coronary or carotid artery revascularization,
•History of previous pancreatitis,
•History of medullary thyroid cancer,
•Atrial fibrillation,
•Any other condition likely to limit protocol compliance (judged by investigator).
•For diabetic patients, patients should not be on Sodium-glucose cotransporter 2 (SGLT2) inhibitor or pioglitazone during the duration of the study, unless these drugs can be stopped without affecting participants' medical condition. For those on Dipeptidyl peptidase-4 (DPP IV) inhibitor, this agent will be discontinued if the patient is randomised to the intervention group.
•Known allergies to Acetazolamide.
•Women who are pregnant or breastfeeding.
