Classification of Antibiotics
Inhibitors of Cell Wall Synthesis These antibiotics target the bacterial cell wall, leading to lysis and death. Beta-lactams: Interfere with peptidoglycan synthesis by inhibiting penicillin-binding proteins (PBPs).Examples: Glycopeptides: Bind to peptidoglycan precursors, preventing cross-linking.Examples: Vancomycin, Teicoplanin. Others: Bacitracin (used topically). Inhibitors of Protein Synthesis These antibiotics target bacterial ribosomes, disrupting ... Read More

Importance of Drug Optimization
Let’s talk about the importance of “Drug optimization” which is a crucial concept in medicinal chemistry and drug design. It refers to the strategy of replacing one chemical group with another that has similar biological activity but different pharmacokinetic properties. For example, consider two NSAIDs available in the market which ... Read More
Citric Acid Cycle: A Journey Into Cellular Metabolism
The Citric Acid Cycle, also known as the Krebs Cycle or TCA Cycle, is foundational to understanding how our cells produce energy. This intricate pathway converts nutrients into usable energy, driving every cellular function. Let’s delve into the details of this essential cycle and its broader implications. The Central Role ...

Impurity Specification Across Different Regulatory Bodies
Impurities in pharmaceutical products play a critical role in ensuring drug quality, safety, and efficacy. Regulatory bodies such as the USFDA, EMA, PMDA, and others have specific guidelines for identifying, quantifying, and controlling impurities. Types of Impurities Key Guidelines for Impurity Control USFDA EMA PMDA (Japan) WHO Indian Pharmacopeia Differences ... Read More
Justification for Control of Elemental Impurities in Formulation
Introduction Definition: Elemental impurities are trace levels of metals that can be introduced into drug products from raw materials, manufacturing processes, or container closure systems. Regulatory requirement: ICH Q3D and relevant pharmacopeial guidelines (USP <232>, <233>) specify acceptable limits for elemental impurities to ensure patient safety. Identification of Potential Sources ... Read More
Trend Analysis for Elemental Impurities
Trend analysis for elemental impurities is not explicitly required by guidelines like ICH Q3D . However, certain aspects of stability trends and variability need to be considered to ensure compliance and accurate reporting. Stability Trends for Elemental Impurities In most cases, if no such risk is identified, monitoring for trends ... Read More
Mastering the Art of Peak Integration in HPLC
Peak integration in High-Performance Liquid Chromatography (HPLC) is more than just a routine step—it’s the bridge between your experiment and the data-driven decisions that follow. Every peak tells a story, and accurate integration ensures you’re interpreting it correctly. Why is Peak Integration Crucial?The area under the curve (AUC) of a ... Read More
Effect of pH in Analytical Method
As a chromatographer not many of us are aware of how critical pH is in your method development, sometimes it is even considered as an inconsequential factor, which could have a negligible effect on our analysis. However, in truth pH can make or break your analysis, choosing the correct or ... Read More
Media and Buffers in Dissolution Method Development
Sink Conditions: Volume of medium should be at least 3 times that needed to form a saturated solution (USP definition). pH Range: Typical range is 1.1 to 6.8, but can be adjusted up to pH 8.0 for solubility. Common Buffers: Surfactants: Medium Deaeration: Ensure medium is deaerated to prevent bubbles, ... Read More
