Powder Shape and Their Effect on Tablet Properties
The pharmaceutical industry relies heavily on powders for the formulation of solid dosage forms, particularly tablets. Powder properties, including particle size and shape, directly affect the manufacturing process and the performance of the final product. While particle size has been extensively studied, the influence of particle shape has garnered increasing ... Read More
Does an F2 Similarity Value of 50 Mean the Two Dissolution Profiles are Only 50% Similar?
No, the similarity factor (F2) is a mathematical representation of the quadratic mean difference between two dissolution profiles across all considered time points. An F2 value of 50 indicates that the two profiles differ by a small margin, with a mean difference of approximately 10%. The similarity factor is not ... Read More
Prevention or Delay of Diabetes | Standards of Care in Diabetes 2024
In people with prediabetes, monitor for the development of type 2 diabetes at least annually; modify based on individual risk assessment. Refer adults with overweight or obesity at high risk of DM2, as seen in the Diabetes Prevention Program (DPP), to an intensive lifestyle behavior change program to achieve and ... Read More
Mind Mapping Tool for Investigations
Mind mapping can be an incredibly effective tool in pharmaceutical investigations, helping teams structure their thinking, uncover connections, and generate insights systematically. Here’s how it can be applied effectively: Applications of Mind Mapping in Pharmaceutical Investigations Root Cause Analysis: During investigations of deviations, out-of-specification (OOS) results, or adverse events, mind ...

Critical Material Attributes (CMAs) of Excipients
When focusing solely CMAs of excipients, the same principles of API apply. These attributes influence the performance and manufacturability of the final drug product and are critical for achieving consistency in pharmaceutical formulations. Critical Material Attributes of Excipients Physical Properties Particle Size Distribution (PSD): Bulk Density and Tap Density: Specific ... Read More
Discriminating Dissolution Media
Discriminating Dissolution Media is a critical component in pharmaceutical formulation development, designed to identify differences in the dissolution performance of drug products. These media are particularly useful when addressing formulation changes, variations in API properties, or manufacturing process alterations. Key Features of a Discriminating Dissolution Medium Examples of Common Discriminating ... Read More
Reference Standard (RS) in Bioequivalence Studies
Introduction In pharmaceutical development, a Reference Standard (RS), often referred to as a Reference Listed Drug (RLD) or comparator product, is a benchmark for evaluating the performance of generic drugs in bioequivalence (BE) studies. The RS ensures that generic drugs meet therapeutic equivalence standards, a critical step for regulatory approval. ... Read More
Alcohol Dose Dumping | A Critical Pharmaceutical Challenge
Introduction Alcohol dose dumping occurs when controlled-release formulations release their active ingredient rapidly in the presence of alcohol. This unintended release can lead to elevated drug levels, increasing risks of toxicity, side effects, or overdose. Mechanisms of Alcohol Dose Dumping Drugs at Risk Clinical Implications Preventive Measures Patient Strategies Regulatory ... Read More
Key Considerations for Generic Formulation Development
Generic formulation development is a complex process designed to create bioequivalent, cost-effective alternatives to innovator products while meeting regulatory standards. Below are the critical aspects to consider: Regulatory Compliance Ensure adherence to market-specific regulatory guidelines, such as those of USFDA, EMA, or MHRA, to obtain approval for generic products. Bioequivalence ... Read More
Citrus Food with Substrate of Pgp and CYP3A4
Do we know that jabara is a Japanese citrus that is similar to yuzu and is consumed as an anti-allergic functional food in Japan and worldwide? We have previously discussed how grapefruit juice interacts with medications (drugs). A question arises: does jabara also interact with drugs? Guess what? It has ... Read More
Concepts of Elimination Rate and Clearance of Drugs
Have we come across a presenter who commented that the ‘clearance rate of a drug is high or low’? A question arises: Is clearance an elimination rate of a given drug? Some of us remain unclear regarding the concepts of elimination rate and clearance of drugs. Elimination rate is the ... Read More
