Case Study

A pharmaceutical company provided BOC Sciences with a compounded dosage form that had stability issues. The company observed unexpected changes in the drug's physical appearance and potency overtime, leading to concerns about the presence of impurities in the formulation. BOC Sciences performs a comprehensive analysis of the compounded dosage form to identify and quantify any impurities present.

Case study of analysis services

Methods: BOC Sciences utilized a combination of analytical techniques including high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), and nuclear magnetic resonance (NMR) to identify impurities in compounded dosage forms. Our team also performed stress testing and accelerated stability studies to simulate conditions that could lead to impurity formation.

Results: Through analysis, BOC Sciences identified multiple impurities in the compounded dosage form, including degradation products of the active pharmaceutical ingredient and by-products of excipients used in the formulation. The team identified the root causes of impurity formation, such as exposure to light, heat and moisture during storage and handling. Based on these findings, BOC Sciences recommended formulation and packaging modifications to minimize impurity formation and improve drug product stability.


1. What is drug analysis?

Drug analysis is based on drug quality standards to detect and analyze the relevant ingredients and contents in drugs to evaluate the quality and authenticity of the drugs. Drug analysis and testing can study the composition, physical and chemical properties, authenticity identification, purity inspection and content of active ingredients of drugs and their preparations, and ensure that people use drugs safely, reasonably and effectively. Before carrying out drug analysis, it is necessary to be equipped with suitable drug quality testing equipment and other instruments, which is the basis for ensuring the development of drug quality inspection work. When conducting drug analysis, it is necessary to strictly abide by the inspection operation procedures to ensure that the drug quality test results are accurate and reliable.

2. What are the methods of drug analysis?

Drug analysis is a critical process involving the identification, quantification, and evaluation of drugs and their metabolites in biological samples. One of the most commonly used methods for drug analysis is chromatography, including gas chromatography (GC) and high-performance liquid chromatography (HPLC), which are widely used in drug analysis. In addition, MS is often used in conjunction with chromatography to improve the sensitivity and selectivity of pharmaceutical analysis. There are several types of MS, including liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS), which are commonly used for pharmaceutical analysis. MS has high sensitivity and can detect drugs at very low concentrations, making it an important tool for drug analysis.

3. What is the principle of drug analysis?

Samples for drug quality inspection include samples of medicinal raw materials, excipients, semi-finished products, packaging materials, waste generated during the production process, and materials directly or indirectly related to drugs. Inspection samples and methods need to be verified by relevant authorized personnel and drug inspection personnel in accordance with regulations, and the inspection report must be recorded and completed and submitted for review in a timely manner. Drug analysis and testing are crucial to drug research and development. Through drug analysis methods, the efficacy, main ingredients, and physical and chemical properties of the drug can be understood.
