Among the newly studied medicinal plants is Zizyphus spina-christi L. which was investigated for its antidiabetic activity against type II diabetes. Formulation of different leaf extracts and standardization of the chosen extract using its major identified saponin as active marker was performed using HPLC. Evaluation of anti-diabetic activity of ex...

Abstract 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...

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...

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...

A hexane extract of the flower-heads of Euryops pectinatus L. (Cass.) was formulated into local anti-inflammatory implantation patches with controlled release. Cross-linked sodium hyaluronate patches (F1-F3) and chitosan patches (F4-F6) were prepared by a casting/solvent evaporation technique. Morphological and mechanical characterizations includin...

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. On day 5, liver injury was induced in animals by a single i.p. injection of carbon tetrachloride (10...

Synopsis Solid lipid nanoparticle (SLN) was regarded as new topical delivery systems for pharmaceutical and cosmetic active ingredients. The purpose of this study is to develop carrier systems for organic and inorganic sunscreens based on a matrix composed of carnauba wax and decyl oleate. Formulae (F1–F7) were prepared using butyl methoxydibenzoyl...

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) wer...

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. Percentage yield of extracts, marker yield (christinin-A) and antihyperglycemic potencies, depending on seasonal variation were investigated. The chemical stability, study of storage cond...

This work describes the formulation of ophthalmic delivery systems of Moxifloxacin (Mox), as a model drug of fourth fluoroquinolone generation. Seven formulations (P1-P7) based on the concept of temperature triggered in situ gelation using pluronic (PL), and nine formulations (C1-C9) based on pH triggered in situ gelation using carbopol 934 (CL), w...

The bioactive aqueous extract of Nigella sativa L. seed waste was formulated into soft gelatin capsules (Su1-Su6) in a dose of 200 mg/kg b. w. using different pharmaceutical excipients: soya lecithin/ span80/ sodium taurocholate, PEG 400, and Meglyol 810. The formulations were evaluated for their immunostimmulant and hepatoprotective activities usi...

This study deals with the formulation of antihyperglycemic leaf extracts of Zizyphus spina-christi (L.) Willd. A bioactivity guided fractionation of different leaf extracts [defatted ethanol 70% (a), butanol (b), ethanol 70% (c), ethyl acetate (d) and petroleum ether (e) extracts] revealed that extract (c) possessed the highest antihyperglycemic ac...

Liquid crystal systems are used to tailor drug delivery from topical delivery system. Ternary polyoxyethylene [21] stearyl ether/ oil and water form liquid crystalline system cream, which has a potential as dosage form for 1% itraconazole as topical dermal drug delivery. Evaluation of the suggested formula was performed for the best physical perfor...
