Description

L-Arginine Acetylsalicylate is a pharmaceutically relevant salt formed from the amino acid L-arginine and acetylsalicylic acid (aspirin). This compound is engineered to enhance the solubility and bioavailability profile of aspirin, offering a more targeted therapeutic approach. It is primarily utilized in the pharmaceutical and nutraceutical industries for the development of advanced analgesic, anti-inflammatory, and cardiovascular formulations.

Application

• Pharmaceutical Intermediates: Serves as a key active pharmaceutical ingredient (API) or precursor in the synthesis of novel analgesic and anti-inflammatory drugs.
• Cardiovascular Health Supplements: Incorporated into nutraceutical formulations aimed at supporting vascular health and blood flow regulation.
• Pain Management Solutions: Used in the development of advanced, buffered aspirin products designed for improved gastric tolerance and efficacy.
• Research & Development: A critical compound for biochemical and pharmacological research studying nitric oxide pathways and antiplatelet mechanisms.
• Veterinary Pharmaceuticals: Applied in veterinary medicine for pain relief and anti-inflammatory treatments in animals.
