Investigating the Potential of Phosphatidylcholine-Based Nano-Sized Carriers in Boosting the Oto-Topical Delivery of Caroverine: in vitro Characterization, Stability Assessment and ex vivo Transport Studies.

Purpose: Drug delivery into the inner ear across the intact tympanic membrane (TM) has been a challenge in the treatment of inner ear disorders. In this study, nano-sized carriers were formulated for improving the non- invasive oto-topical delivery of caroverine for the treatment of tinnitus.

Methods: Caroverine was loaded into two types of phospholipid-containing systems, namely, nano elastic vesicles (EVs) and phosphatidylcholine-based liquid crystalline nano-particles (PC-LCNPs).

Pharmaceutical and medical aspects of hyaluronic acid-ketorolac combination therapy in osteoarthritis treatment: radiographic imaging and bone mineral density.

The objective of this study was to formulate novel painless combined hyaluronic acid (HA)-ketorolac (KT) membrane for the management of osteoarthritis with rapid analgesic onset, thus avoiding HA frequent invasive intra-articular injections and KT gastrointestinal complaints associated with all non-steroidal anti-inflammatory drugs. HA was chemically crosslinked with carbodiimide/glutaraldehyde to yield membrane of low water content. Different in vitro aspects (mechanical properties, water content and in vitro release) were studied leading to an optimized soft, flexible K8 HA membrane containing 30 mg KT that achieved the desired balance of excellent elasticity and low water content.

Moxifloxacin-Gelrite in situ ophthalmic gelling system against photodynamic therapy for treatment of bacterial corneal inflammation.

In this study, six in situ gelling formulations based on Gelrite were prepared and evaluated for the retained ophthalmic delivery of Moxifloxacin (Mox). The effectiveness of the best developed formula G5 was compared with photodynamic therapy (PDT), the recent expanding approach for the treatment of ophthalmologic disorders after the assessment of optimum photodynamic inactivation parameters that permit efficient pathogens eradication. It was found that, Staphylococcus aureus (S.

Development of novel transdermal self-adhesive films for tenoxicam, an anti-inflammatory drug.

Aim: The purpose of this study was to develop transdermal films (TFs) with the addition of different polymer ratios that incorporated 0.5% tenoxicam in order to ensure maximum controlled and sustained drug release capacity. Tenoxicam is a non-steroidal anti-inflammatory drug (NSAID) widely used in the treatment of rheumatic diseases and characterized by its efficacy and reduced side effects in comparison to other NSAIDs.

Ophthalmic delivery of sparfloxacin from in situ gel formulation for treatment of experimentally induced bacterial keratitis.

The objective of the present work was (1) to develop an in situ gelling ophthalmic delivery system by combining pluronic F127 and pluronic F68, with sparfloxacin; and (2) to examine the influence of incorporating a mucoadhesive polysaccharide such as sodium hyaluronate on the healing property due to bacterial keratitis. The formulations (F1-F6) were sterilized by gamma irradiated using Co(60) . Ultraviolet (UV) and infrared (IR) spectra studies were performed on sterilized and non-sterilized formulae.

Phytochemical and biological investigation of the extracts of Nigella sativa L. seed waste.

Different extracts of Nigella sativa L. seed waste; aqueous (AE) 200 mg/kg, ethanol 70% (EE) 250 mg/kg and hexane (HE) 10 mg/kg, were evaluated for their hepatoprotective activities. They were administered orally, once daily, for 5 consecutive days.

Anti-diabetic activity and stability study of the formulated leaf extract of Zizyphus spina-christi (L.) Willd with the influence of seasonal variation.

Aim Of The Study: The present study aimed to evaluate the anti-diabetic activity of Zizyphus spina-christi leaf extract (200 mg/kg b.w.), plain and formulated in STZ-diabetic rats.
