Olanzapine (OL) is an atypical antipsychotic drug which suffers from extensive hepatic metabolism and poor bioavailability. In addition, it has low brain permeability due to efflux by P-glycoproteins. the current investigation, surface modified niosomes containing OL were prepared for targeting of through nasal route. Spans mixed with cholesterol at ratios 1:1, 1:2, 1:3, 1:4 surfactant, respectively prepare niosomes. Chitosan (CS) coated vesicles mixing optimum niosomal formula CS solution...

Porcine buccal mucosa is abundantly used in drug delivery studies. With the emergence of new barrier models, such as cell culture a link between these models and traditional porcine should be established. The examination was divided into two experiments: uptake different solvents an infinite dose permeation study domperidone from solvent systems through EpiOral™ tissue models; this aims to find correlation models. experiment revealed superb water by dried (>300% increase weight) high with...

The present study aimed to formulate and evaluate metformin sterosomes. Sterosomes were prepared by incorporating stearylamine cholesterol in different ratios. characterized using size, zeta potential, entrapment efficiency (EE%) vitro release. Aerosol generated nebulization was evaluated a cooled Andersen cascade impactor (ACI) at 15 L/min. In cytotoxicity of free metformin-containing sterosomes tested against human cancer cell lines. A comparative pharmacokinetic between sterosomal...

The aim of this work was to study the effect using training device (In-Check DIAL) along with traditional dry powder inhaler (DPI) counseling on inhalation technique and pulmonary functions test (PFT) in asthmatics. Adult asthmatics >18 years old were recruited 3months investigation training. They divided into control groups. DPI checked mistakes noted corrected at every monthly visit. Their peak expiratory flow forced volume 1second as percentage vital capacity each visit followed by...

The oral administration of celecoxib (CLX) is a real problem because its low aqueous solubility that results in high variability absorption and severe adverse effect such as cardiotoxic effects gastrointestinal toxicity. Self-nanoemulsifying drug delivery systems (SNEDDS) can enhance the poor dissolution erratic poorly water-soluble drugs CLX. This study was conducted to investigate potential SNEDDS efficacy CLX on inflamed mucous tissue reduce systemic by increasing properties. A...

The aim of the present study is to formulate highly permeable carriers (i.e., transethosomes) for enhancing delivery prednisolone combined with tacrolimus both topical and systemic pathological conditions. A Box-Behnken experimental design was implemented in this research. Three independent variables: surfactant concentration (X1), ethanol (X2), (X3) were adopted while three responses: entrapment efficiency (Y1), vesicle size (Y2), zeta potential (Y3) investigated. By applying analysis, one...

Background and Objectives: Fibrotic lung disease is one of the main complications many medical conditions. Therefore, use anti-fibrotic agents may provide a chance to prevent, or at least modify, such complication. The aim this study was evaluate protective pulmonary anti-inflammatory effects Dinebra retroflexa. Materials methods: retroflexa methanolic extract its synthesized silver nanoparticles were tested on bleomycin-induced fibrosis. Pulmonary fibrosis induced by intratracheal...
