Mucoadhesive and Drug Release Properties of Benzocaine Gel
Gel dosage forms are successfully used as drug delivery systems considering their ability to control drug release and to protect medicaments from a hostile environment. The aim of this work was to investigate the properties of carbopol 934P polymeric system in water-misible cosolvents such as glycerin and alcohol. Benzocaine is a local anesthetic and the mucosal gel formulation is appl...

متن کاملDrug volume fraction profile in the gel phase and drug release kinetics in hydroxypropylmethyl cellulose matrices containing a soluble drug.
In the present work, the drug volume fraction profiles of a colored and very soluble drug, buflomedil pyridoxal phosphate, in the gel layer of initially glassy hydroxypropylmethyl cellulose matrices were studied, using image analysis of pictures of the matrices during swelling and release. The goal was to correlate the drug release kinetics with the dynamic behavior of the drug gradient in the ...
متن کاملBiological glass fibers: correlation between optical and structural properties.
Biological systems have, through the course of time, evolved unique solutions for complex optical problems. These solutions are often achieved through a sophisticated control of fine structural features. Here we present a detailed study of the optical properties of basalia spicules from the glass sponge Euplectella aspergillum and reconcile them with structural characteristics. We show these bi...
متن کاملExcellent correlation between drug release and portal size in metalla-cage drug-delivery systems.
A series of large cationic hexanuclear metalla-prisms, [Ru(6)(p-iPrC(6)H(4)Me)(6)(tpt)(2)(donq)(3)](6+), [Ru(6)(p-iPrC(6)H(4)Me)(6)(tpt)(2)(doaq)(3)](6+) and [Ru(6)(p-iPrC(6)H(4)Me)(6)(tpt)(2)(dotq)(3)](6+), composed of p-cymene-ruthenium building blocks bridged by OO∩OO ligands (donq=5,8-dioxido-1,4-naphthoquinonato; doaq=5,8-dioxido-1,4-anthraquinonato, dotq=6,11-dioxido-5,12-naphthacenediona...
