Vesicular delivery systems have been reported to serve as local depot for sustained drug release. Aceclofenac multilamellar liposomes and niosomes were prepared and a comparative study was done between them through evaluation of entrapment efficiency, particle size, shape, differential scanning calorimetry and in vitro drug release. A stability study was(More)
The purpose of this study was to prepare lipospheres containing aceclofenac intended for topical skin delivery with the aim of exploiting the favorable properties of this carrier system and developing a sustained release formula to overcome the side effects resulting from aceclofenac oral administration. Lipospheres were prepared using different lipid cores(More)
Fungal infections are amongst the most commonly encountered diseases affecting the skin. Treatment approaches include both topical and oral antifungal agents. The topical route is generally preferred due to the possible side effects of oral medication. Advances in the field of formulation may soon render outdated conventional products such as creams,(More)
Several types of Michael acceptors, including alpha,beta-unsaturated ketones, lactones, and lactams, have been extensively studied as potential anticancer agents. A concerted effort was made to explore the relationship between the structures of these compounds and their antitumor activity against P388 and L1210 leukemias. This article describes the(More)
With the aid of the computer, approximately 8000 compounds that incorporate a carbamate or thiocarbamate moiety, which have been tested as potential anticancer agents at the National Cancer Institute (NCI), were classified and their structure-activity correlations against the in vivo P-388 and L-1210 leukemias were evaluated. Aromatic carbamates and(More)
Risedronate sodium was formulated into polylactide-co-glycolic acid microspheres for pulmonary delivery using the w/o/w double emulsion technique. Sodium chloride was used as osmogen in either the internal or external aqueous phase to surface-engineer the particles to achieve favorable properties. The prepared microspheres were characterized for the surface(More)
A challenging disease such as lung cancer requires the combination of different modalities to achieve beneficial therapeutic outcomes. In this work, PLGA nanoparticles were chosen as colloidal carrier for two drugs with reported anti-lung cancer activity: naringin and celecoxib. PLGA nanoparticles were prepared and characterized for their particle size,(More)
Amphotericin B (AmB) lipid nanoemulsions were prepared and characterized and their suitability for pulmonary delivery via nebulization was evaluated. AmB nanoemulsions were prepared by sonicating and vortexing the drug with two commercially available lipid nanoemulsions: the Intralipid(®) or Clinoleic(®). Loading the nanoemulsions with the drug slightly(More)
Polyamidoamine (PAMAM) dendrimers were evaluated as nanocarriers for pulmonary delivery of the model poorly soluble anti-asthma drug beclometasone dipropionate (BDP) using G3, G4 and G4(12) dendrimers. BDP-loaded dendrimers were characterized for drug solubility, in vitro drug release and aerosolization properties using three nebulizers: Pari LC Sprint(More)
OBJECTIVE This study aims at testing the hypothesis that reversed phase evaporation liposomes (REVs) are suitable for systemic delivery of an anti-osteporotic drug (risedronate sodium (RS)) via pulmonary nebulization. MATERIALS AND METHODS RS REVs were prepared using phospholipids and cholesterol with or without stearylamine, and were characterized for(More)
