Oral Anti-diabetic drugs[OADs]

Introduction

Oral Anti-diabetic Drugs[OADs] are those medicines that are given mostly to Type 2 Diabetic patients.

After discussing the importance of Insulin injection in my last post, we now come to the treatment of diabetes mellitus with Oral Anti-diabetic drugs[OADs].

A large number of oral antidiabetic drugs are available. Each drug has its own advantages[ good effect] as well as disadvantages[ side effects]. These medications help those having persistent hyperglycemia.

Precautions to be taken while taking Oral Anti-diabetic drugs-

OADs should be prescribed in people having diabetes with diet advice [esp. those already on low-glycemic indexed foods] and exercise, keeping in mind:-

a] Conservation of insulin-producing β- cells of the pancreas and thereby delay initiation of Insulin injections;

b] Decrease episodes of hypoglycemia[low blood glucose levels];

c] Improve patient compliance;

d] Reduce the cost burden and affordability of the patients;

e] Improve Insulin resistance and reduce hypoglycemic attacks;

f] HbA1c levels;

g] Lady having Gestational Diabetes
