1A Silver nanoparticle based hydrogel prepared by green synthesis Wound Healing GelA Silver nanoparticle based hydrogelprepared by green synthesis
2Novelty/Inventive component The product uses nanoparticle of silver formed by green synthesisSocial RelevanceIts an OTC product with vast market potentialUse of herbal product has better market acceptabilityHence very much required by the societyCommercial PotentialThe new product uses 0.02% silver nitrate while the traditional ones like Silverex® (Ranbaxy) uses 0.2% w/w. It’s a 10 times reduction in the quantity of silver used.
3Proof of concept: Wound healing activity in Swiss Albino Wistar Rats.
4PROPOSAL AIMS ATAim: Seeking approval for further investigation regarding safety & stability of the product & conduct clinical trialKey deliverables:Evaluation of safety & stability of the product using analytical/bio-analytical method following ICH guidelinesEvaluation of microbial load in final product & identification of suitable preservative.Conducting Phase – I clinical trial.
5To establish safety, stability and efficacy through clinical trials OBJECTIVESTo establish safety, stability and efficacy through clinical trialsWork PlanStep 1 – Assessment of safety of the product: Skin irritation studies will be carried out using rabbits by Drazie test. The irritancy score shall be computed and based on response of skin.Step 2 - Stability of the product: Effect of varying storage conditions on product stability/efficacy will be evaluated using suitable analytical/ bio-analytical method as per ICH guideline.Step 3 – Evaluation and reduction of microbial load: Microbial load of the formulation will be assessed and attempt will be made to reduce the microbial load by incorporating preservative at optimum concentration.Step 4 – Clinical trials: The safety/efficacy of the product will be proven through clinical trials.
6ENVISAGED OUTCOME OF THE STUDY The outcome of the project would be a comparatively cost effective formulation for treatment of wound healing that will be based on newer nanotechnology. The product will demonstrate adequate stability & safety.After successful safety & stability test and DCGI approval, this project will go to Phase-2 for clinical trail study.
15Preparation of formulation Silver Nitrate Addition of herbal extract Formation of colloidal nanoparticles after heating Addition of gelling polymer & preservative Allow to stand overnight Product
