Polymorph screens and salt screens are important components for drug development. The goal of polymorph screening is to try to find all possible crystal forms by small-scale crystallization and to select a stable form that can be manufactured and formulated into a dosage form. Salt screens are commonly used to alter the physicochemical properties of Read more
Improved Pharma, LLC participated in the AAPS PharmSci 360 meeting in San Antonio, TX from Nov 3-6, 2019. The meeting was highly successful and allowed for several discussions surrounding our problem solving strategy. Our booth was ideally located among several formulation companies and the formulation poster sessions, enabling a great forum for gathering scientists Read more

Non-crystalline phases such as amorphous states can lead to increased solubility for drugs. However, amorphous materials are notoriously unstable and tend to crystallize over time. As such, many amorphous materials are created in a dispersion with a polymer to increase their physical stability. X-ray powder diffraction patterns of amorphous materials are broad and not useful Read more
Current approaches to accelerated drug development typically involve parallel track activities utilizing sophisticated project management capabilities. Improved Pharma has developed a strategy that continues to utilize these project management tools but in addition utilizes predictive tools based on structure analysis of formulations and anticipation of major instabilities of formulations by assessing formulation risk. Orphan drugs Read more
Dr. Stephen Byrn and his co-authors have published an updated and thorough textbook focused on solid-state properties of pharmaceutical materials. Building off of his first textbook, Solid-State Chemistry of Drugs, this newest publication brings together solid-state chemistry, key analytical techniques, critical physical attributes, and a strategic approach for selecting and producing the correct form. With Read more
