Design of in-situ implant for the brain-targeted drug delivery using cross-linked gellan gum polymer through response surface methodology.
The analysis aimed to prepare an in-situ implant (ISFI) formulation holding dimethyl fumarate as (a model drug) using cross-linked gellan gum by homogenization method. Cross-linking of gellan gum was done with L-cysteine to improve its gelation properties. Fourier transform infrared spectroscopy (FTIR) and (DSC) Differential scanning calorimetry were used to test the compatibility of the drug-polymer. The diverse formulations were prepared and tested using Design Expert® ver 8.0.1 software to optimize the experiment technique and employ the response surface. The tissue compatibility of the test verified the existence of non-irritants in the established formulation. All preparations contained the drug content from approximately 97.98 to 99.88%. Viscosities are ideal for injection in the optimized formulation (1,55 percent w/w in water). The optimized formula was monitored, and up to 156hours, it was found to be 95.7%. The result was that ISFI can effectively monitor and control the delivery of several powerful drug products.
期刊介绍：
This journal proposes a scientific information validated and indexed to be informed about the last research works in all the domains interesting the pharmacy. The original works, general reviews, the focusing, the brief notes, subjected by the best academics and the professionals, propose a synthetic approach of the last progress accomplished in the concerned sectors. The thematic Sessions and the – life of the Academy – resume the communications which, presented in front of the national Academy of pharmacy, are in the heart of the current events.
