Q

How does metformin work?

A

Increases sensitvity to insulin
Decreasing hepatic glucose production by decreasing glyconeogenesis
Increase glucose uptake by skeletal muscles
Inhibit GI glucose absorbtion

Q

What considerations are issued for TZDs and SU/GLNs when considering as 1st/2nd/3rd line agents?

A

Caution is advised due to side affects:
TZDs -actos (CHF, fracture risk and weight gain)
Sulfonylureas (SU) “ides” & Meglitinides (GLN) “linides”- (weight gain, ASCD risk)

Q

TZDs (zones) works by what mechanism?

A

Actos/Avandia works are also sensitizers activate a nuclear receptor (PPAR Gama gene) which increases use of insulin by the liver, muscle cells and adipose tissue.
Also reduces hepatic glucose production so that appropriate amount of glucagon is produced.

Q

How do secretagogues work?

A

Close potassium channel in the beta cells which opens the calcium channel thusly increasing insulin secretion.

Q

Which type of drug’s main benefit is for patients with post prandial glucose spikes and why?

A

Meglitinides (Prandin/Starlix) are both short acting pro insulin secreting drugs. Works similar to normal insulin response to elevated glucose.
The are usually administered TID PP
