Q

What are the key challenges for patients with Type 2 diabetes in terms of patient adherence and quality of life?

Q

What is the NICE target for Hbac1 for treating patients with Type II Diabetes?

A

In general target for all is HbA1c 6.5 to 7.5%

  • HbA1c 6.5%: Diet and first 2 treatment steps
  • HbA1c 7.5%: Beyond this or if at risk of severe hypoglycaemia
17
Q

Describe the four effects of metformin on the body

A
  • ↓ insulin resistance leading to increased glucose by tissues
  • ↓ hepatic gluconeogenesis
  • Limits weight gain
  • ↓ CVS events
18
Q

What are the side effects of metformin?

A
  • GI symptoms (nausea, loose stools, diarrhoea)
  • Vitamin B12 deficiency (uncommon)
  • Lactic acidosis (rare)
19
Q

Describe the two effects of sulphonylureas on the body

A
  • Stimulate beta cell to release insulin
  • ↓ Microvascular risk
20
Q

What are the side effects of sulphonylureas?

A
  • Weight gain
  • Hypoglycaemia
21
Q

Describe the effects of acarbose, an α glucosidase inhibitor, on the body

A

Acarbose Inhibits the breakdown of carbohydrates to glucose by blocking action of the enzyme α glucosidase

22
Q

What are the side effects of acarbose?

A

Predictable:

  • Flatulence
  • Loose stools
  • Diarrhoea
23
Q

Describe the 3 effects of glitazones on the body

A
  • ↑ insulin sensitivity in muscle and adipose tissue
  • ↓ hepatic glucose output
  • Bind to and activate 1/more peroxisome proliferator-activated receptors (PPARs)
24
Q

Describe the side effects for the following glitazone drugs:

  • Rosiglitazone
  • Pioglitazone
A
  • Rosiglitazone – CVS concerns
  • Pioglitazone – weight gain, fluid retention, heart failure, effects on bone metabolism and bladder cancer
25
Q

Describe the mechanism and use of glucagon like peptide 1 therapies

A
  • Mechanism: alternative hormone system influencing glucose metabolism
  • Use: high glucose in Type II diabetes due to insufficient release of insulin and over production of glucagon
26
Q

Identify three drugs used in GLP 1 therapy

A
  • Exenatide
  • Liraglutide
  • Lixisenatide
27
Q

Describe the physiological effects of GLP 1 therapies on the pancreas

A
  • Increase insulin secretion from the beta cells
  • Decreases production of glucagon from alpha cells
28
Q

Describe the physiological effects of GLP-1 therapies on the following organs/structures:

  • Pancreas
  • Liver
  • Brain
  • Stomach
  • Muscle
A

Pancreas

↑insulin secretion

↑ insulin biosynthesis

↓ glucagon secretion

Liver ( indirect effect )

↓ glucagon production

Brain

↓ food intake through increased satiety

Stomach

↓ gastric emptying

Muscle

↑ glucose uptake

29
Q

What are the side effects of GLP 1 agonists?

A
  • GI symptoms (nausea, loose stools, diarrhoea)
  • Gastro oesophageal reflux
  • Hypoglycaemia (low risk)
  • Pancreatitis and pancreatic carcinoma (possible)
30
Q

Identify a contra-indication for GLP 1 agonists

A

Avoid if eGFR < 30ml/min

31
Q

Provide four examples of Gliptins (/ DPP-4 inhibitors)

A
  • Sitagliptin
  • Vildagliptin
  • Saxagliptin
  • Linagliptin
32
Q

Describe the effects of gliptins on the body

A

Inhibits DPP-4 activity by increasing postprandial active GLP-1 concentrations

33
Q

What are the side effects of gliptins?

A
  • GI symptoms (nausea, loose stools, diarrhoea)
  • Pancreatitis
  • Hypoglycaemia (low risk)
  • HbA1c reduction (modest)
34
Q

When are glifozins used?

A

Glifozins can be used for patients with Type I and Type II diabetes as add on therapy

35
Q

Provide three examples of glifozins

A
  • Dapagliflozin
  • Canagliflozin
  • Empagliflozin
36
Q

What are the side effects of glifozins?

A
  • Lower urinary tract symptoms (increased risk)
  • Polyuria
  • Hypoglycaemia (low risk)
