Description

Aloxiprin is a polymeric derivative of acetylsalicylic acid, designed to provide a controlled-release mechanism. This compound is significant for its improved gastric tolerance compared to conventional aspirin, making it a valuable active pharmaceutical ingredient (API) in specific therapeutic formulations. It is primarily needed by pharmaceutical manufacturers developing analgesic and anti-inflammatory medications, particularly those targeting patients requiring long-term salicylate therapy.

Application

• Pharmaceutical API: Core ingredient in the formulation of enteric-coated or sustained-release analgesic tablets and capsules.
• Anti-inflammatory Medications: Used in products designed for the management of chronic inflammatory conditions like arthritis.
• Analgesic Preparations: Formulated into medications for the relief of mild to moderate pain with reduced gastric irritation.
• Cardiovascular Prophylaxis: Potential use in long-term, low-dose antiplatelet therapy formulations for improved patient compliance.
• Veterinary Pharmaceuticals: Applied in controlled-release pain management solutions for animals.
• Clinical Research: Serves as a reference standard or investigational material in pharmacokinetic and drug delivery studies.

Quality Control

Our Aloxiprin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets pharmaceutical-grade specifications, including identification, assay, and impurity profile analysis. A Certificate of Analysis (COA) documenting compliance with relevant in-house or customer-specific specifications is provided with every shipment.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and performance.
