Studying the API Distribution of Controlled Release Formulations Produced via Continuous Twin-Screw…
Abstract
Hydroxypropyl methylcellulose (HPMC) is a preferred hydrophilic matrix former for controlled release formulations produced through continuous twin-screw wet granulation. However, a non-homogeneous API distribution over sieve fractions with underdosing in the fines fraction (<150 µm) was…

Optimization of Hydroxypropyl Methylcellulose (HPMC) and Carbopol 940 in Clindamycin HCl Ethosomal…
Clindamycin HCl has anti-acne properties because it can inhibit the growth of Propionibacterium acnes (P. acnes) bacteria. However, the bioavailability of clindamycin HCl is less than 13% of the given dose, so it needs to be developed in the form of ethosomes to increase its bioavailability. This…

Effects of excipients on the interactions of self-emulsifying drug delivery systems with human blood…
Due to its versatility in formulation and manufacturing, self-emulsifying drug delivery systems (SEDDS) can be used to design parenteral formulations. Therefore, it is necessary to understand the effects of excipients on the behavior of SEDDS formulations upon parenteral administration, particularly…

Equivalence assessment of creams with quali-quantitative differences in light of the EMA and FDA…
Abstract
EMA and FDA are upgrading guidelines on assessing the quality and the equivalence of topically applied drug products for developing copies of originator products and supporting post-marketing variations. For topical products having remarkably similar composition, both EMA and FDA accept…

Drinkable in situ-forming tough hydrogels for gastrointestinal therapeutics
Abstract
Pills are a cornerstone of medicine but can be challenging to swallow. While liquid formulations are easier to ingest, they lack the capacity to localize therapeutics with excipients nor act as controlled release devices. Here we describe drug formulations based on liquid in situ-forming…

Development of a New Bioequivalent Omeprazole Product
Abstract
Background and Objectives: The enteric form of omeprazole is one of the most commonly prescribed medications. Similarly to Europe, Kazakhstan relies on the localization of pharmaceutical drug production as one of its primary strategies to ensure that its population has access to affordable…

Novel inhalable powder formulation of pirfenidone with sustained release properties to improve…
Abstract
The aim of this study was to develop a new respirable powder (RP) formulation of pirfenidone (PFD) with sustained release properties to ameliorate the pharmacokinetic drawbacks of the previously-developed PFD-RP on rapid elimination from the lung after insufflation. Based on screenings…

Self-microemulsifying system of an ethanolic extract of Heliopsis longipes root for enhanced…
Abstract
Self-microemulsifying or self-nanoemulsifying drug delivery systems (SMEDDS/SNEDDS) are well known to improve the dissolution and increase the oral bioavailability of hydrophobic drugs, including herbal extracts. Organic extracts of Heliopsis longipes root and affinin, its main component,…
