Sitagliptin for sale

Sitagliptin is an oral antihyperglycemic  of the dipeptidyl peptidase-4 (DPP-4) inhibitor class. It was developed, and is marketed, by Merck & Co. This enzyme-inhibiting drug is used either alone or in combination with other oral antihyperglycemic agents (such as metformin or a thiazolidinedione) for treatment of diabetes mellitus type  The benefit of this medicine is its fewer side effects (e.g:less hypoglycemia, less weight gain) in the control of blood glucose values.
It is used to help control blood sugar levels in people with type 2 diabetes (non-insulin dependent diabetes). People with type 2 diabetes either do not produce enough insulin to control blood sugar levels or do not respond properly to the insulin that is made. Sitagliptin acts by enhancing the action of a hormone known as glucagon-like polypeptide 1 (GLP-1) and this leads to increased levels of insulin and lower blood sugar levels. It is used when diet and exercise have not sufficiently controlled the blood sugar levels. Sitagliptin can be used on its own or in combination with other oral blood glucose lowering medications to treat type 2 diabetes.
