Environmental and Quality Monitoring Through Pharmaceutical Analysis: A Quantitative Assay of Acetylsalicylic Acid Content in Commercial Aspirin Tablets Available in Pharmacies of Kalar City/Iraq

This study evaluated the quality of acetylsalicylic acid (aspirin) in commercial tablet brands from Kalar City pharmacies, located in eastern Iraq, to ensure medications meet safety and efficacy standards. Given the diverse sources of global drug production, quality control in pharmaceuticals remains crucial. The research employed classical analytical methods, including direct and back titration, as alternatives to when standard methods aren't accessible. Results showed varying consistency across five tested brands. One brand demonstrated the highest reliability and dosage accuracy, indicating superior quality assurance, while significant discrepancies in other brands raised concerns about formulation integrity and labeling accuracy. The findings emphasize that relying solely on labeled dosage is insufficient to guarantee therapeutic efficacy. This study contributes to pharmaceutical quality control efforts and underscores the necessity for routine market surveillance and standardized testing protocols to ensure patient safety through comprehensive quality control testing.
