The drug delivery system in breast cancer therapy with the thermosensitive hydrogel method developed significantly due to influence of availability various polymers which have characteristics that are affected by changes temperature. Drug release from gel preparations has advantages over traditional intravenous release. Despite fact injectable capability gradual and sustained release, is unpred...

Objective(s): Ketotifen fumarate (KF) is a selective and noncompetitive histamine antagonist (H1-receptor) that is used topically in the treatment of allergic conditions of rhinitis and conjunctivitis. The aim of this study was to formulate and improve an ophthalmic delivery system of KF.Ocular nanoparticles were prepared with the objective of reducing the frequency of administration and obtain...

Background: Tolmetin (Tol) is a pyrrole acetic acid derivative that acts as a highly effective topical anti-inflammatory agent. Topical administration of Tol is effective for the management of ocular inflammations.The aim of this study was to formulate and improve a topical ophthalmic delivery system of Tol. Materials and methods: In the present study, ocular inserts of Tol were prepared using ...

BACKGROUND Nano bamboo charcoal is being widely used as sustained release carrier for chemicals for its high specific surface area, sound biocompatibility, and nontoxicity; however, there have been no reports on nano bamboo charcoal as sustained release carrier for traditional Chinese medicine (TCM). OBJECTIVE To study the effect of nano bamboo charcoal in absorbing and sustained releasing Eu...

Abstract Here, we report the results of experiments regarding chemical repositioning 4‐(2‐hydroxyethyl)‐1‐piperazine ethane sulfonic acid ( HEPES ), a representative buffering agent. In this work, confirmed that could disaggregate amyloid plaques, hallmark Alzheimer's disease, and verified its sustained‐release system (release for up to 2 weeks) via hybridization with biocompatible polymer (Eud...

Growth factors are a class of cytokines that stimulate cell growth and are widely used in clinical practice, such as wound healing, revascularization, bone repair, and nervous system disease. However, free growth factors have a short half-life and are instable in vivo. Therefore, the search of excellent carriers to enhance sustained release of growth factors in vivo has become an area of intens...
