Bioavailability & Solubility
PERMEABILITY STUDIES – Onion Epithelial Membrane as a Model for Predicting Intestinal Absorption of Drugs
Antoine Al-Achi, PhD, Mounika Nangineedi, MS, Chaitali Koli, MS, et al, study 19 drugs with varying partition coefficient, water solubility, and molecular weight values to compare their diffusion through the middle epithelial membrane of onion with that of their Caco-2 cell line.
Contributor Cindy H. Dubin interviews several leading companies on how they are using innovative technologies, such as lipid nanoparticles to achieve a high drug loading, combining anti-solvent continuous crystallization with micro-mixing technology to control crystallization and reduce crystal size, and how a robotic capsule can improve bioavailability in the range of 47% to 78%.
FORMULATION DEVELOPMENT – Impact of Excipients & Manufacturing Process on Solubility-Enhanced Ritonavir Tablet Size & Weight Reduction
Gayatri Khanvilkar, MPharm, Ajit Bhagat, and Tejas Gunjikar, PhD, investigate bulking agents and disintegrants to develop efficacious Rotonavir tablets with improved in vitro release.
FORMULATION FORUM – Formulation & Process of Lipid Nanoparticles for Delivery of Small Molecules & Biologicals
Jim Huang, PhD, explains how recently, lipid nanoparticles have emerged as a drug delivery system for biologicals, especially for the COVID-19 mRNA vaccines in which LNPs play a vital role in transporting mRNA into the target cells.
For each participating company, this section presents a detailed summary highlighting their core technologies, capabilities, technologies, and services.
Jim Huang, PhD, says a thorough understanding of their amorphous stabilization and nano colloidal properties in relationship to in-vitro and in-vivo performance will help advance this interesting dosage form into human clinical testing and commercialization.
EXECUTIVE INTERVIEW – Quotient Sciences: Unique Considerations & Challenges When Developing Palatable Pediatric Formulations
Nazim Kanji, Executive Director, Pediatric Services at Quotient Sciences, discusses the unique considerations and challenges when developing palatable pediatric formulations, so that molecules can become cures, fast.
Bob Wieden and Chun Wang, PhD, discuss how significant challenges, coupled with the complexity and diversity of new pharmaceuticals, have fueled the development of a novel polymeric drug delivery platform that overcomes a great many bioavailability and delivery obstacles.
Ameya Deshpande, MS, says for APIs that are compatible with HME, careful attention to the formulation quality attributes that include excipient selection, dosage form design, analytical testing, and stability are required to maximize the efficacy and quality of the final product.
In this month’s column on formulation development challenges, Jim Huang, PhD, discusses nanosuspensions prepared via the top-down process, ie, the wet milling process.
