You should do an optimization process. First, you have to choose the best gelling agent in order to get a stable gel. For example, you may try to make gelss with different kind of gelling agent. After you get the best gelling agent, you may try different concentration in order to get the optimum formula. Then, you may add some excipients to prevent drug oxidation or degradation.
Thanks for your answers Christopher and Delly. However, I wanted to know if someone has already worked on this product before to make a stable gel of aceclofenac.
thanks a lot for the link but I can not access the complete link as it is payable. I'm only able to go through its abstract. Please download and send me the full text if you have access to it.
