Pharma Stability: Insights, Guidelines, and Expertise
Introduction to Microbiological Degradation Microbiological degradation involves the contamination of drug products by microorganisms such as bacteria, fungi, and molds. These contaminants can proliferate under certain conditions and lead to changes in product quality, safety, and efficacy. Common Microbiological Degradation Pathways Let’s explore some of the most common microbiological degradation pathways observed in pharmaceutical products:…
Introduction to Temperature Stability Temperature is one of the most critical factors influencing the stability of pharmaceutical products. Fluctuations in temperature can accelerate chemical reactions, promote physical changes, and facilitate microbial growth, ultimately affecting the quality and efficacy of drugs. Impact of Temperature on Drug Stability Let’s explore how temperature affects the stability of drugs:…
Introduction to Humidity Stability Humidity refers to the moisture content present in the air or environment surrounding pharmaceutical products. It is a critical factor that can impact the stability, quality, and efficacy of drugs, especially those sensitive to moisture. Impact of Humidity on Drug Stability Let’s explore how humidity affects the stability of drugs: 1….
Introduction to pH Stability pH, a measure of the acidity or alkalinity of a solution, is a critical factor that can significantly influence the stability, solubility, and efficacy of pharmaceutical products. Changes in pH can impact chemical reactions, physical properties, and drug interactions within formulations. Impact of pH on Drug Stability Let’s explore how pH…
Introduction to Shelf-life and Expiration Dating Shelf-life refers to the period during which a drug product maintains its intended quality, potency, and safety under defined storage conditions. Expiration dating is the date assigned to a drug product, indicating the end of its shelf-life and the time after which it should not be used. Shelf-life Determination…
