Study of drug quality in the Indian market
India is an increasingly influential player in the global pharmaceutical market. A pilot study, conducted in two major cities in India, Delhi and Chennai, explored the proliferation of substandard and counterfeit drugs in the market and discussed how the Indian state and federal governments could improve drug regulation and regulatory enforcement to combat this.
India is an increasingly influential player in the global pharmaceutical market. A pilot study, conducted in two major cities in India, Delhi and Chennai, explored the proliferation of substandard and counterfeit drugs in the market and discussed how the Indian state and federal governments could improve drug regulation and regulatory enforcement to combat this.1
Random samples of antimalarial, antibiotic and antimycobacterial drugs were collected from pharmacies and analysed with semi-quantitative thin-layer chromatography and disintegration testing to measure the concentration of active ingredients against internationally acceptable standards. 12% of all samples tested from Delhi failed either one or both tests and were substandard. 5% of all samples tested from Chennai failed either one or both tests and were substandard.
According to the study the prevalence of substandard drugs in Delhi and Chennai is confirmed to be roughly in accordance with the Indian government's current estimates. However, it also states that important spatial and product heterogeneity exists, which suggests that India's substandard drug problem is not ubiquitous, but driven by a subset of manufacturers and pharmacies that thrive in an inadequately regulated environment. It is recommended that the drug regulatory system in India needs to be improved for domestic consumption, and because India is an increasingly important exporter of drugs for both developed and developing countries.
Next Generation Peak Fitting for Separations
December 11th 2024Separation scientists frequently encounter critical pairs that are difficult to separate in a complex mixture. To save time and expensive solvents, an effective alternative to conventional screening protocols or mathematical peak width reduction is called iterative curve fitting.

December 11th 2024In this installment of "LC Troubleshooting," Dwight Stoll discusses several essential principles related to when and why buffers are important, as well as practical factors, such as commonly used buffering agents, that are recommended for use with different types of detectors.
USP CEO Discusses Quality and Partnership in Pharma
December 11th 2024Ronald Piervincenzi, chief executive officer of the United States Pharmacoepia, focused on how collaboration and component quality can improve worldwide pharmaceutical production standards during a lecture at the Eastern Analytical Symposium (EAS) last month.
Overcoming Common Challenges to Determine Residual Impurities Using IC in APIs with Limited Water
December 10th 2024Organic solvents are generally not compatible with ion chromatography (IC) systems. The approach presented here assists the use of organic solvents for sample preparation and provides a mechanism for the removal of the organic solvents from the chromatographic flow path.
