Galvus Tablet

Introduction

Galvus Tablet 50 mg is an oral antidiabetic medication used to manage type 2 diabetes mellitus. It belongs to the class of drugs known as dipeptidyl peptidase-4 (DPP-4) inhibitors. It helps to regulate blood sugar levels by enhancing the body's natural ability to lower blood glucose.

Uses

Galvus Tablet 50 mg is primarily used for:

• Managing blood glucose levels in adults with type 2 diabetes mellitus.
• It is often used in combination with other antidiabetic agents, including metformin, sulfonylureas, or thiazolidinediones, when diet and exercise alone are insufficient.

Mechanism of Action

Galvus Tablet 50 mg works by inhibiting the enzyme dipeptidyl peptidase-4 (DPP-4). This enzyme breaks down incretin hormones, such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP). By inhibiting DPP-4, Galvus Tablet 50 mg increases the levels of these incretin hormones, which enhances insulin secretion from the pancreas and decreases glucagon levels, leading to improved blood glucose control.

How Long Does It Take to Work?

The effects of Galvus Tablet 50 mg can be observed within a few weeks of starting treatment. Optimal blood glucose control is generally achieved within 1 to 2 months of consistent use. The time to see significant improvements in glycemic control can vary depending on individual patient factors and the presence of other antidiabetic medications.

Absorption

Galvus Tablet 50 mg is rapidly absorbed after oral administration. Peak plasma concentrations are reached approximately 1 to 2 hours post-ingestion. The bioavailability of Galvus Tablet 50 mg is around 85%, meaning that a significant proportion of the administered dose is available for therapeutic effect.

Route of Elimination

Galvus Tablet 50 mg is primarily eliminated through the kidneys. Approximately 70% of the dose is excreted unchanged in the urine. A small proportion is metabolized in the liver and subsequently excreted in the urine.

Dosage

• 50 mg twice daily (morning and evening) when used in dual combination with Metformin or a Thiazolidinedione;
• 50 mg once daily in the morning when used in dual combination with a Sulphonylurea.

The typical starting dose of Galvus Tablet 50 mg is 50 mg taken orally once or twice daily. Depending on the patient's response and tolerance, the dose may be adjusted.
