Diabetes

Troglitazone (Rezulin)

This drug is the first of a new class indicated in the treatment of Type II diabetes. It works by increasing the effectiveness of circulating insulin. It is of particular value in lowering (10-23%) and stabilizing the insulin requirements of patients with Type II diabetes who require insulin for control of blood glucose. Adverse effects include: an increased incidence of urinary tract infections, headache, and weakness. Due to reports of liver damage, periodic monitoring of liver function is recommended.

Acarbose (Precose), Miglitol (Glycet)

These are representatives of a new class of drugs which are oral non-absorbed agents for the treatment of non-insulin dependent diabetes. They act in the intestine by reducing the conversion of disaccharides to absorbable simple sugars. This results in a dose-dependent reduction of blood sugar from 20-80 mg/dl. A dose-dependent reduction of HbA1c of 0.5-1.00% is also observed. It may be used a monotherapy or combined with a sulfonylurea. As expected, the major side effects are gastrointestinal and include abdominal pain, diarrhea, and flatulence (which can occur in up to 80% of patients). Slow titration of dose upwards can reduce the gastrointestinal side effects.

Side effects are rare with abdominal pain, bloating, headache and constipation the most frequently reported.
