Formulation and Characterization of Cinnarizine Targeted Aural Transfersomal Gel for Vertigo Treatment: A Pharmacokinetic Study on Rabbits.

Introduction And Aim: Cinnarizine is indicated orally for treating vertigo associated with Ménière's syndrome and has a local anesthetic effect as well. The present study aims to develop an aural Cinnarizine mucoadhesive transfersomal gel to overcome the first-pass metabolism.

Methods: Eighteen Cinnarizine transfersomes were prepared by the thin-film hydration technique using different types of phosphatidylcholine and edge activators in different ratios.

Solutol HS15 based binary mixed micelles with penetration enhancers for augmented corneal delivery of sertaconazole nitrate: optimization, in vitro, ex vivo and in vivo characterization.

Keratomycosis is a serious corneal disease that can cause a permanent visual disability if not treated effectively. Sertaconazole nitrate (STZ), a novel broad spectrum antifungal drug, was suggested as a promising treatment. However, its utility in the ocular route is restricted by its poor solubility, along with other problems facing the ocular delivery like short residence time, and the existing corneal barrier.

Corneal targeted Sertaconazole nitrate loaded cubosomes: Preparation, statistical optimization, in vitro characterization, ex vivo permeation and in vivo studies.

Sertaconazole nitrate (STZ) is a poorly soluble antifungal drug commonly used for treating fungal skin infections. Introducing it as a new treatment option for the management of fungal keratitis, requires the development of a delivery system capable of targeting the infected cornea with an adequate STZ concentration. Hence, Sertaconazole nitrate loaded cubosomes (STZ-CUBs) were prepared, characterized and optimized based on a 3 central composite face-centred design.

Non-ionic surfactant based vesicular drug delivery system for topical delivery of caffeine for treatment of cellulite: design, formulation, characterization, histological anti-cellulite activity, and pharmacokinetic evaluation.

Cellulite is a common topographical alteration where skin acquires an orange peel or mattress appearance with alterations in adipose tissue and microcirculation. This work aims to develop and evaluate a topical niosomal gel formulae with good permeation to reach the subcutaneous fat layer. Several caffeine niosomal dispersions were prepared and incorporated into gel formulae using Carbopol 940 polymer, chemical penetration enhancers, and iontophoresis, then the prepared gels were applied onto the skin of rats and anticellulite activity of caffeine from the prepared gels compared to that of the commercial product Cellu Destock was evaluated by histological study of the skin and measurement of plasma level of caffeine passing through the skin using liquid chromatography (LC/MS-MS).

Formulation and evaluation of injectable in situ forming microparticles for sustained delivery of lornoxicam.

The objective of this study is to formulate biodegradable in situ microparticles (ISM) containing lornoxicam for post-operative and arthritic pain management. ISM emulsions were prepared according to 2 full factorial experimental design to investigate the influence of formulation variables on the release profile of the drug. The independent variables studied are the polymer type, polymer inherent viscosity, polymer concentration, oil type and polymer:oil ratio.
