In the present study, the stabilizing effect of excipients present in recombinant Human Serum Albumin (rHSA) solutions are studied using rheological analysis. The study was conducted using Design of Experiment (DoE) principles and multivariate analysis approach. It is observed that the excipients octanoate and polysorbate 80 used in the Recombumin Alpha® formulation both increase the stability of the protein reflected by an observed decrease in the complex viscosity interpreted as a decreasing...

The aim of the current study was to formulate Fexofenadine hydrochloride loaded sustained release microspheres using HPMC K100 M CR, a release retardant hydrophilic polymer by solvent evaporation method. The effect of different drug loading on drug content, drug encapsulation efficiency and release of drug was monitored. The studies on in vitro release mechanism were performed using USP paddle method with 900 ml of phosphate buffer (pH 6.8) for 10 h at 100 rpm. The mechanism of the drug release...

Meloxicam (MLX) is a non-steroidal anti-inflammatory drug (NSAIDs) from the Oxicam family. This group of NSAIDs has been highly used in the treatment of rheumatoid arthritis and post-operative inflammation and is known as good antioxidants. Recently, their activity in chemoprevention, chemo-suppression, UV-sensitization and UV protection as also identified. MLX has been described as a COX-2 selective inhibitor. Its use has some advantages regarding to its selectivity, namely, less adverse...

Abstract Excipients represent diverse classes of molecules, small molecules or macromolecules, with versatile structures within a given class and are from natural, semi-synthetic and synthetic sources. They are essential ingredients in drug products independently of the route of administration where both traditional and non-traditional uses are present. Beyond their traditional use as formulation and manufacturing aids, certain excipients exhibit biological effects and thus can be used either...

Smoking cessation is of current topical interest due to the significant negative health and economic impact in many countries. This study aimed to develop buccal films and wafers comprising HPMC and sodium alginate (SA) for potential use in nicotine replacement therapy via the buccal mucosa, as a cheap but effective alternative to currently used nicotine patch and chewing gum. The formulations were characterised using texture analyser (tensile and hardness, mucoadhesion), scanning electron...

Abstract: Drug nanocrystals are a versatile option for drug delivery purposes, and while the number of poorly soluble drug materials is all the time increasing, more research in this area is performed. Drug nanocrystals have a simple structure—a solid drug core is surrounded by a layer of stabilizing agent. However, despite the considerably simple structure, the selection of an appropriate stabilizer for a certain drug can be challenging. Mostly, the stabilizer selection is based purely on...

Abstract: Preparation of drug nanoparticles via wet media milling (nanomilling) is a very versatile drug delivery platform and is suitable for oral, injectable, inhalable, and buccal applications. Wet media milling followed by various drying processes has become a well-established and proven formulation approach especially for bioavailability enhancement of poorly water-soluble drugs. It has several advantages such as organic solvent-free processing, tunable and relatively high drug loading,...

Orally disintegrating tablets (ODTs) are dosage forms which disintegrate in mouth within seconds without need of water. This type of quality in dosage form can be attained by addition of different varieties of excipients. PharmaburstTM 500 is a co-processed excipient system which allows rapid disintegration and low adhesion to punches. The aim of the present study was to develop and evaluate 25 mg diclofenac sodium ODTs (orodispersible tablets) batches by direct compression method at different...

Dry eye disease (DED) has been reported to afflict 7–33% of the population, thereby reducing their quality of life. For normal vision, continuous moistening of the ocular surface is needed. Important roles are played in this by a sufficient quality of tears, maintenance of the normal composition of the tear film, normal lid closure, and regular blinking [1, 2]. If equilibrium is lost, the DED can occur, resulting in eye discomfort and visual disturbance [2, 3]. DED is accompanied by changes...
