ABSTRACT: Bosentan is an endothelial receptor antagonist (ERA) indicated for the treatment of Pulmonary arterial hypertension (PAH). The aim of the present study involves the development of controlled release tablets of bosentan1. The tablets were prepared to release the drug for a prolong period of time within the GIT, to enhance the bioavailability, to minimize the dosing frequency, and to improve the patient compliance2. The tablets were formulated by using various polymers like hydroxyl...

Abstract Predictive in vitro test methods addressing the parameters relevant to drug release in the pediatric gastrointestinal tract could be an appropriate means for reducing the number of in vivo studies in children. However, dissolution models addressing the particular features of pediatric gastrointestinal physiology and typical pediatric dosing scenarios have not yet been described. The objective of the present study was to combine the knowledge on common vehicle types and properties and...

Abstract Gastrointestinal drug administration is the preferred route for the majority of drugs however, the natural physiology and physicochemistry of the gastrointestinal tract is critical to absorption but complex and influenced by factors such as diet or disease. The pharmaceutical sciences drive for product consistency has led to the development of in vitro product performance tests whose utility and interpretation is hindered by the complexity, variability and a lack of understanding. This...
