Oramet-SR 500 mg Tablet

Oramet-SR 500 mg Tablet — Metformin Hydrochloride (Sustained Release)

Overview

Oramet-SR 500 is a sustained-release metformin tablet from Drug International Ltd., formulated for once-daily dosing convenience with steadier blood levels and typically improved gastrointestinal tolerability compared to immediate-release tablets.

Mechanism of Action

Metformin reduces hepatic glucose production, decreases intestinal glucose absorption, and improves peripheral insulin sensitivity. The sustained-release formulation releases the drug gradually over several hours, supporting once-daily dosing.

Indications

Oramet-SR 500 is indicated for type 2 diabetes mellitus, particularly suited to patients who prefer once-daily dosing or who experience gastrointestinal side effects with immediate-release metformin.

Dosage and Administration

Typically taken once daily with the evening meal; sustained-release tablets must be swallowed whole and never crushed, split, or chewed.

Contraindications

Contraindicated in severe renal impairment (eGFR <30 mL/min/1.73m²), metabolic acidosis including diabetic ketoacidosis, and known hypersensitivity to metformin.

Side Effects

Generally better gastrointestinal tolerability than immediate-release formulations, though nausea, diarrhea, or abdominal discomfort can still occur. Long-term use may reduce vitamin B12 absorption.

Drug Interactions

Iodinated contrast media require temporary discontinuation of metformin. Alcohol intake should be limited. Disclose all current medications and supplements to your physician or pharmacist.

Special Precautions

Patients may occasionally notice the tablet matrix in stool; this is expected and does not indicate reduced effectiveness. Renal function should be monitored periodically.

Storage

Store below 30°C in a dry place, protected from light. Keep out of reach of children.
