42-48 mmol/mol
Diabetic HbA1c level
Diabetic fasting plasma glucose levels
48mmol/L
7mmol/L
DPP-4 inhibitors
‘GLIPTINS’
- linagliptin
- sitagliptin

Treatment of type 2 diabetes in someone with a LOW CVD risk
Step 1: Metformin
Step 2: pioglitazone or gliclazide
Step 3: triple therapy
- adding/ swapping with SGLT-2s or DPP-4i
Factors that consider someone HIGH CVD risk with type 2 diabetes
- established atherosclerosic CVD or HF
- QRISK > 10% in those over 40
Treatment of type 2 diabetes in someone with a HIGH CVD risk
STEP 1: Metformin
STEP 2: + SGLT2 inhibitor (once metformin tolerated)
- SGLT2 used alone if metformin not tolerated
STEP 3: same as LOW CVD risk
Which antidiabetic drugs are associated with HYPOglycaemia?
Sulphonylureas
Insulin
MHRA warning with metformin
Reduced levels of vitamin B12
- this can cause fatigue, weakness, and neurological issues like numbness and tingling in the extremities
Side effects associated with metformin
Lactic acidosis
GI side effects- N&V (give MR preparation)
what renal function should metformin be avoided in?
- why
If eGFR<30ml/min/1.73m2
- increases risk of LACTIC acidosis
STOP IN AKI
When should DPP-4 inhibitors be used with caution?
- ‘gliptins’
Heart failure
Avoid: ketoacidosis
When should DPP-4i’s be discontinued?
If pancreatitis develops
- persistent severe abdominal pain
Contraindications of pioglitazone?
Heart failure
what can pioglitazone increase the risk of?
Bladder cancer
Bone fractures
Infections
Liver toxicity
What are the symptoms associated with bladder cancer due to pioglitazone?
- When is it reviewed?
Haematuria (blood in urine)
Dysuria/ urinary urgency
Urinary urgency
- reviewed for efficacy after 3-6 months
When are sulphonylureas (gliclazide) usually given?
If the patient has a higher HbA1c as a rescue therapy
3 MHRA warnings accosted with SGLT-2 inhibitors
- Life threatening DKA
- Monitor ketones if treatment is interrupted due to a surgical procedure or illness
- Fournier gangrene
MHRA warning associated with canagliflozin?
Risk of lower-limb amputation (mainly toes)
What must be corrected before starting treatment with SGLT-2 inhibitors?
What is common side effect of SGLT-2 inhibitors?
Volume depletion- correct hypovolemia
Increased risk of urinary tract infections and thrush
What are the MHRA warnings associated with GLP-1 agonists?
- 3
- DKA risk when insulin is rapidly reduced
- Risk of pulmonary aspiration during general anaesthesia or deep sedation
- Potential misuse and reminder of side effects
What are the side effects associated with GLP-1?
Acute pancreatitis- severe abdominal pain
GI effects- weight loss, nausea and vomiting
Dehydration- due to GI side effects
What is acarbose?
- what are the side effects
Delays digestion of starch and sucrose
- gastro intestinal side effects
