Final answer:
The primary purpose of Metformin Hydrochloride; Sitagliptin Phosphate is diabetes management, particularly type 2 diabetes. They work by improving insulin sensitivity and enhancing the function of the pancreas, helping to normalize blood glucose levels.
Step-by-step explanation:
The primary purpose of Metformin Hydrochloride; Sitagliptin Phosphate is for c) Diabetes Management. This combination medication is used primarily in the treatment of type 2 diabetes and works by addressing high blood glucose levels that characterize the condition, also known as hyperglycemia. It acts by improving the insulin sensitivity of the body's cells and enhancing the function of the pancreas. Unlike insulin injections, which were the first-line treatment historically, Metformin and Sitagliptin do not necessarily increase blood glucose levels before consuming a meal. Instead, their function aligns more with reducing blood glucose levels to normal ranges and supporting lifestyle changes such as diet and exercise. It is important for patients with type 2 diabetes to manage their condition with lifestyle changes, but when these are insufficient, medications like Metformin and Sitagliptin can be crucial. They differ from sulfonylureas like gliclazide, which stimulate insulin secretion and can cause hypoglycemia as an adverse effect.
