background: minoxidil has been reported to inhibit in vitro fibroblast proliferation and lysyl hydroxylase activity, a key enzyme in collagen biosynthesis. these in-vitro effects proposed minoxidil to be a potential antifibrotic agent. the present study aimed to investigate the effects of minoxidil gel on wound healing procedure in a second-degree burn model in rats. materials and methods: wis...
This study aimed to develop an intravesical delivery system of gemcitabine HCl for superficial bladder cancer in order to provide a controlled release profile, to prolong the residence time, and to avoid drug elimination via urination. For this aim, bioadhesive nanoparticles were prepared with thiolated chitosan (chitosan-thioglycolic acid conjugate) and were dispersed in bioadhesive chitosan g...
Gel dosage forms are successfully used as drug delivery systems to control drug release and protect the medicaments from a hostile environment. The main objective is to formulate and evaluate in situ oral topical gels of clotrimazole based on the concept of pH triggered and ion activated systems. The system utilizes polymers that exhibit sol-to-gel phase transition due to change in specific phy...
Various solubilizers were tried during preformulation study. Propylene glycol and Transcutol were selected as solubilizers for further study. Poloxamer 407 gives gelation temperature in nasal temperature range 280 to 350 in 18% w/v concentration. Addition of bioadhesive polymer from 0.2% to 0.7% further lowered the gelation temperature from 340 to 290. Gelation temperatures obtained using two d...
objective: adequate knowledge about restorative materials particularly flowable composite resins with favorable physical properties like optimal microhardness and resistance to environmental factors is a big concern for many dentists. flowable composites have several applications for fissure sealant therapy and preventive resin restorations (prr) which are common treatments in pediatric dentist...
Purpose: Approximately 30% higher grade premalignant oral intraepithelial neoplasia (OIN) lesions will progress to oral cancer. Although surgery is theOIN treatmentmainstay,manyOIN lesions recur, which is highly problematic for both surgeons andpatients. This clinical trial assessed the chemopreventive efficacy of a natural product-based bioadhesive gel on OIN lesions. Experimental Design: This...
PURPOSE We prepared and characterized topical ophthalmic formulations containing brimonidine-loaded bioadhesive cationic chitosan or anionic alginate nanoparticles (NPs) for sustained release of brimonidine as once daily regimen for management of glaucoma. METHODS Nanoparticles were prepared using a spontaneous emulsification solvent diffusion method. Different concentrations of polymers, emu...
The present study concerned with the development and characterization of metronidazole microcapsules prepared by thermal change method using different ratios (1:1, 1:2 and 1:4) of ethyl cellulose in order to select the best microcapsule formulation with a good encapsulation efficiency and drug release profile. The obtained microcapsules were discrete, spherical with free flowing properties and ...
