Introduction
Diabetes is considered as insulin secretion deficiency that diagnosed easily by low blood glucose level (Wilson, 2001). There are very common signs and symptoms such as polyphagia, polyuria and polydipsia, thus major complications will be observed from gangrene, glaucoma, kidney failure, and nervous diseases to cardiovascular complications (Wilson, 2001).
Classifications of anti-diabetic drugs
A. Injected insulin According to Wilson (2001), it is a chemically synthetic injected …show more content…

Drug interactions
According to Inzucchi and McGuire (2008),
1. Insulin, alcohol, MAOI and salicylates: hypoglycemia
2. Dicumarol, chloramphenicol and MAOI: reduce hepatic metabolism of sulphonylurea
3. Sulfonamide, probencid and salicylates: reduce urinary excretion of sulphonylurea

2. Biguanides e.g. metformin
Mechanism of action
Anti-hyperglycemia will be achieved through many steps; decreasing glycogen breakdown, improving insulin sensitivity in the tissues and decreasing glucose synthesis by the liver and its absorption by the intestine (Inzucchi and McGuire, 2008).
Uses
Used mainly in controlling hyperglycemia, either alone or in combination with sulphonylurea. Also it has anti-hypertension effect (Inzucchia and McGuire, 2008).
Adverse effects
Cause lactic acidosis and many GIT problems such as anorexia, nausea and vomiting (Inzucchi and McGuire, 2008).
Drug interactions
As Inzucchi and McGuire (2008) said that,
1. Deficiency of vitamin B12 and folic acid when taken with it: decrease their absorption
2. Ibubrufen, propranolol, nifedipine and glyburide: hyperglycemia
3. Quinidine, cimetidine and trimethoprim: reduce metformin elimination and increase its serum concentration.

3. Alpha glucosidase inhibitors e.g. Miglitol
Mechanism of action
They inhibits alpha amylase enzyme that is responsible for carbohydrate digestion and so delay their absorption from the intestine in order to manage diabetes (Nathan, et. al., 2008).
