Acetaminophen (APAP) administration results in hepatotoxicity and hematotoxicity in cats. The response to three different treatments against APAP poisoning was evaluated. Free glutathione (GSH) (200mg/kg), niosomal GSH (14 mg/kg) and free amino acids (180 mg/kg of N-acetylcysteine and 280 mg/kg of methionine) were administered to cats that were intoxicated with APAP (a single dose of 150 mg/kg,...

Niosomes have been reported as possible approach to improve the low corneal penetration and bioavailability characteristics for many drugs. The purpose of this study was to prepare and characterize an effective ocular niosomal hydrogel containing 0.5% (w/v) atenolol which is β1 adrenoceptor blocker for treatment of glaucoma. Thin film hydration method was used for the preparation of niosomes us...

BACKGROUND Efficacy of topical methotrexate in psoriasis is limited by its penetration. AIMS The study involved the preparation of niosomal methotrexate in chitosan gel and to test the same for irritation and sensitization on healthy human volunteers followed by assessing the efficacy of the gel through double-blind placebo-controlled study on psoriasis patients and also comparing its efficac...

Due to the drawback of conventional therapy for ocular delivery like poor bioavailability of drugs due to tear production, non productive absorption, transient residence time, impermeability of corneal epithelium. These problems can be minimized by the application of niosomal vesicular system as well as combination of drugs provides the additive effect on reduction of IOP. The aim of the presen...

On admixture of non-ionic surfactant of the alkyl or dialkyl polyglycerol ether class and cholesterol with subsequent hydration in aqueous media, microscopic lamellar structures formed are known as niosomes or non-ionic surfactant vesicles. Method of preparation of niosome is same as of liposome technology i.e. hydration by aqueous phase of the lipid phase which may be either a pure surfactant ...

PURPOSE A niosome based transdermal drug delivery system of Nimesulide (NIM) was developed and extensively characterized and evaluated for in-vitro performance followed by in-vivo evaluation in rats by carrageenan induced rat paw edema method. METHOD Niosomes were prepared by lipid film hydration technique using tweens and spans. Preparation of niosomes was optimized for highest percent drug ...

Topical beta-blocking agents are nowadays the drugs of choice as these have few ocular and systemic side effects. In the present study some selected beta blockers (PP-24, PP-34, PP-41, PP-48, PP-50), synthesized using 4-hydroxybenzaldehyde and isovanillin were encapsulated into niosomes possessing a high drug entrapment efficiency in order to be used as ophthalmic carriers for topical ocular tr...

Niosomes as a vesicular system are well documented for delivering drugs, in controlled manner to enhance bioavailability and get better therapeutic effect over a longer period of time. Celecoxib is a NSAID, selective COX-2 inhibitor, which is used for treatment of rheumatoid arthritis, osteoarthritis and acute pain. The present study dealt with the preparation and characterization of celecoxib ...

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 ...

Objective: Niosomal gel formulations containing phenytoin sodium have been prepared for enhancing skin wound healing. Methods: Solvent evaporation-film hydration methodology was adopted for noisome formation. Different compositions of phenytoin, surfactant and cholesterol were tested. The prepared niosomes were evaluated for size of vesicles, drug entrapment efficiency and release profiles. Res...
