Microenvironmental pH modulation in solid dosage forms.
Microenvironmental pH modulation was shown to control the dissolution profile of both immediate and controlled release dosage forms of compounds with pH dependent solubility and pH modifiers have been used in conjunction with high energy or salt forms in immediate release formulations.
Impact of Excipient Interactions on Solid Dosage Form Stability
Emerging aspects in terms of limitations of drug-excipient compatibility studies, emerging paradigms in accelerated stability testing, and application of mathematical modeling for prediction of drug product stability are discussed.
Effect of process parameters on compressibility of granulation manufactured in a high-shear mixer.
Mechanistic basis for the effects of process parameters on quality attributes in high shear wet granulation.
NIR chemical imaging to guide/support BMS-561389 tablet formulation development.
Role of drug substance material properties in the processibility and performance of a wet granulated product.
Assessing materials' tablet compaction properties using the Drucker–Prager Cap model
Molecular Basis of Crystal Morphology-Dependent Adhesion Behavior of Mefenamic Acid During Tableting
Higher surface exposure of polar functional groups correlates with higher tendency to stick to metal surfaces and AFM tips, indicating involvement of specific polar interactions in the adhesion behavior.
Effect of different acids on solid-state stability of an ester prodrug of a IIb/IIIa glycoprotein receptor antagonist.

Adding acids to blends containing DMP 754 and anhydrous lactose improved the stability at 40 degrees C/75% relative humidity and decreased the rate of hydrolysis of the amidine group and this effect was more pronounced with stronger acids.
