In Situ Gelling

The purpose of the present study was to develop intranasal delivery system of dimenhydrinate using thiolated gellan gum and formulations were modulated so as to have gelation at physiological ion content after intranasal administration.  Gelation was determined by physical appearance.  The mucoadhesive force in terms of detachment stress, determined using sheep nasal mucosa, increased with increasing concentration of thiolated polymer. The results of in vitro drug permeation studies across sheep nasal mucosa indicate that effective permeation could be significantly increased by using in situ gelling formulation with thiolated polymer concentration.  Finally, histopathological examination did not detect any changes during in vitro permeation studies.  In conclusion the gel formulation of dimenhydrinate with in situ gelling and mucoadhesive properties with increased permeation rate is promising for prolonging nasal residence time and thereby nasal absorption.

The aim of the present study was to evaluate the effect of two surfactants on in vitro permeation of butorphanol through equine nasal mucosa. Franz diffusion cells and equine nasal mucosa were used. Three formulations were developed based on citric acid, sodium citrate, sodium chloride, and butorphanol tartrate and administered at a 24.4 g cm-3 dose. Control formulation lacked any penetration enhancer. Formulation 1 (F1) had a cationic surfactant (cetrimonium bromide) and formulation 2 (F2) had a non-ionic surfactant (Tween 80). Statistically comparing flux values at the steady state (Jss), apparent permeability coefficient (Kp), and lag-time from control, F1 and F2 for the respiratory region does not show statistically significant differences (α= 0.05). However, statistically significant differences were found on the Jss and Kp, values from control, F1, and F2 in olfactory mucosa. A statistical analysis on the latter showed significant differences between the Jss values of F1 and F2 and between control and F2. Based on this, Tween 80 proved to be a promising excipient in developing intranasal butorphanol formulations in equines since it increases its passage through the nasal mucosa. These results are very promising to continue with the development of intranasal butorphanol formulation in equines.

The aim of this work was to prepare and evaluate the topical carbopol gel formulation containing ketoconazole encapsulated liposomes. Ketoconazole loaded liposomes were prepared by thin film hydration technique. The prepared liposomes were incorporated into 1% carbopol gel, and the systems were evaluated for in-vitro drug release, drug retention into skin and in-vitro antifungal activity. The in-vitro permeation of ketoconazole using wistar albino rat skin from liposomal gel was compared with that of plain drug gel and also with plain drug cream containing 2% w/w of ketoconazole. The release of ketoconazole from liposomal gel was much slower than from non liposomal formulations. Gel containing liposomal ketoconazole showed maximum antifungal activity after 30 hours over plain ketoconazole gel and cream formulations.
