Designing and characterizing of tramadol hydrochloride transdermal patches prepared with Ficus carica fruit mucilage and povidone

The purpose of this investigation was to prepare matrix type transdermal patches of Tramadol HCl using various ratios of Ficus carica fruit mucilage and Povidone. The matrix type transdermal patches were prepared using Tramadol HCl with Ficus carica fruit mucilage and Povidone. The interactions between Tramadol HCl with F. carica fruit mucilage and Povidone were performed by Differential Scanning Calorimetry [DSC] and Fourier Transform Infrared spectroscopy [FTIR]. The prepared patches were examined for physicochemical characterization and in vitro drug permeation studies [using a Keshary-Chien diffusion cell across hairless Albino rat skin], skin irritation studies and accelerated stability studies. The drug was found to be free from negligible interactions with the polymers used. The formulated patches possessed satisfactory physicochemical properties, in vitro drug permeation and devoid of serious skin irritation. The selected formulation [F-5] was retains the characteristics even after the accelerated environmental conditions. The study concludes that F. carica fruit mucilage with Povidone is a good combination for preparing transdermal patches

Formulation and evaluation of ficus glomerata mucilage sustained release matrix tablets of gliclazide

The main aim of present investigation was to develop sustained release matrix tablets of Gliclazide using fruit mucilage from the plant Ficus glomerata. Varying ratios of drug and polymer viz. 1:0.25, 1:0.5, 1:0.75, 1:1.0 and 1:1.25 were selected for the study. The flow properties of powdered mucilage and physical properties of matrix tablets were performed. The swelling behavior and release rate characteristics were studied. The in vitro drug release data was analyzed by zero order, first order, Higuchi plot, Peppas plot and Hixon-Crowell Models. It was observed that as the proportion of mucilage increased the release of drug from the matrix tablets was retarded. Stability studies were conducted at 40 +/- 2°C and RH 75 +/- 5% for 3 months indicates that Gliclazide was stable in the matrix tablets. The Differential Scanning Calorimetric [DSC] and Fourier Transform Infrared [FTIR] study revealed that there was no negative chemical interaction between drug and the mucilage used. From the dissolution study, it was concluded that dried Ficus glomerata mucilage can be used as an excipient for making sustained release matrix tablets
