An Introduction to Diabetes Medications

Brief about Diabetes
Human body requires energy to perform daily activities. Energy is also required for internal organs of body for good functionality. Every cell of the body does respiration process to produce energy from the eaten food. A hormone, known as insulin (secreted by pancreas gland), help body cells to use glucose and generate energy out of it. Diabetes is a disease in which body system fails to produce enough insulin. Because of inability of body cells to transform glucose in energy, accumulation of glucose occurs which eventually leads to many diabetes complications.
Types of diabetes: Diabetes Type 1, Diabetes Type 2.

Diabetes Drugs

For type 1 diabetes insulin, pramlintide and exenatide are to be administered by injection or inhalation. Range of oral medicines, belong to different drug-class, are available to treat type 2 diabetes.

Types of Drug For Diabetes

Sulfonylureas

Sulfonylureas is class of drug belong to anti-diabetic drugs they are indicated for both type 1 and 2 diabetes. Sulfonylureas increase insulin release by working on beta cells of pnacrease gland.
Sulfonylureas drugs increase electrical positivity on membrane of beta cells of pancreas gland by preventing polarising of potassium tonic. Increased positivity leads to release more Ca (calcium) which helps stored insulin to release in body.
Drugs that are called sulfonylureas are......

• Acetohexamide
• Tolbutamide
• Chlorpropamide
• Tolazamide

Second generation

• Glipizide

Third generation

• Glimepiride

Working mechanism (Pharmacokinetics) and effect on body (Pharmacodynamics) of these drugs are different, though, their resulting action is same i.e. release of more insulin. With sole purpose of releasing more insulin in body different drugs are formulated with different techniques hence side effects of all drugs are different too.

Meglitinides

Meglitinides are indicated for diabetes type 2. Meglitinides works in same manner as that of sulfonylureas. Like sulfonylureas, meglitinidesin too bind its self but at different place.
Drugs of this class are....
Nepaglinide (Prandin)
Nateglinide (Starlix)
Meglitinide may cause low level of glucose (Hypoglecemia) because of high insulin released. Take it before half an hour of meal.

Biguanides

Biguanides are more effective than sulfonylureas and meglitinide. In stead of increasing insulin level biguanides lowers the process known as Gluconeogenesis that forms glucose. It also helps tissues to absorb glucose.
Metformin belong to this class of diabetes drugs. Metformin is one of the most popular drug being used in combination with other drug for diabetes type 2.

Thiazolidinediones

Thiazolidinediones are also know as glitazones. They acts in two ways to reduce glucose level, reduces natural process of glucose formation; helping cells to utilize glucose. Being greater effective, these drugs shows less side effects.

• Avandia (Rosiglitazone)
• Rezulin (Troglitazone)
• Actos (Pioglitazone)

Thiazodinediones works by sticking itself to receptors called PPARs.
