Abstract In this study, electrostatic charging of lactose and its mixtures with salbutamol sulphate (SS) were studied as a function of relative humidity (RH). Powder adhesion onto a steel pipe surface was also investigated. The powders were charged by sliding in a steel pipe. Increase in RH decreased the charging of lactose and mixtures, but the effect on SS was not evident. Furthermore, the charge of the mixtures reversed from negative to positive as RH was increased and remained positive as...

Surface energies and dynamic vapour sorption (DVS) plays an imparative role in drug polymer interaction in the formulation development for a number of applications. Powdered films of two pH sensitive polymers namely hypromellose phthalate (HPMCP) and methacrylic acid copolymer NF (Eudragit L30-55) were studied for surface energy analysis employing inverse-phase gas chromatography (IGC) which is a well-known physi- cal technique in acquiring significant information about surfaces of...

Abstract Aim: To prepare BSA loaded chitosan nanoparticles by polymerization technique and to study the effect of initiator concentration upon particle size, product yield, entrapment efficiency, loading capacity and drug release from the formulation. Methodology: In the present study BSA loaded chitosan nanoparticles were prepared by polymerization technique. Three formulations were prepared by varying the concentration of Initiator. The concentration of Initiator (Ammonium per sulphate) was...

In the present study an attempt has been made to evaluate Ocimum bascilium mucilage coprocessed with Mannitol as a novel super disintegrant. Coprocessed excipients were prepared by solvent evaporation method and evaluated in the formulation of mouth dissolving tablets of Terbutaline sulphate. Formulated mouth dissolving tablets were characterised for physicochemical parameters like hardness, friability, weight variation, disintegration time, drug content and in vitro drug release behaviour. The...

Oral salbutamol sulphate has site-specific absorption in the stomach and upper part of the small intestine. Its bioavailability is about 40% due to several factors including narrow absorption window and extensive intestinal metabolism. The aim of this study was to formulate and optimize sustained release floating tablets of salbutamol sulphate in order to improve its bioavailability and reduce its dosing frequency......
