Quality Control

Our Distalgesic is manufactured under strict quality systems to meet the rigorous standards of the pharmaceutical industry. Every batch is tested to ensure compliance with relevant pharmacopoeial specifications (such as USP/EP) for identity, purity, and potency. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with each shipment to guarantee traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
