Evaluation of binders in twin-screw wet granulation – Optimal combination of binder and disintegrant
The influence of localization (intragranular, split or extragranular) of three superdisintegrants (croscarmellose sodium, crospovidone, sodium starch glycolate) on granules and tablets after twin-screw granulation was studied. The aim was to find a suitable disintegrant type and disintegrant…

Formulation development and optimization of prasugrel final dosage form by direct compression method
Abstract
Background:
Prasugrel is a member of thienopyridine class of ADP receptors that reduce the aggregation ("Clumping") of platelets by irreversibly binding to P2Y12 receptors.
Objective:
The aim of this study is to develop new formulation of Prasugrel tablets by direct compression…

Development of a Liposomal Gel for Prolonged Ophthalmic Soluble Drug Delivery
Liposome, as a drug delivery vehicle, entraps drugs, releases them sustainably, and modifies release patterns. This entrapment has diminished exposure of the drug to the eye medium, which could minimize adverse effects. In this investigation, 18 formulations in 3 key categories (liposome, gel and…

Hydrogel-forming microarray patch mediated transdermal delivery of tetracycline hydrochloride
Antibiotic resistance is one of the most serious health problems today and is expected to worsen in the coming decades. It has been suggested that antibiotic administration routes that bypass the human gut could potentially tackle this problem. In this work, an antibiotic hydrogel-forming microarray…
