I am trying to find out information about manufacturer of Oxcarbazepine (substitute for Trileptal) as well as other drugs that could be substituted for it, in addition to Trileptal.

The pills are 600 MGs, Baize in color with the number 13 on left and 9 on the right,

I recently refilled my son's prescription at Cleveland Metropolitan Hospital, at the pharmacy, the price increased nearly 100 percent, and I was told it was due to mfr price increase, I would like to know who manufactured it, weather or not they increased price or Metro Hospital did. and if mfr increased price, I'ld like to know any companies that make similar product, so that I can switch mfrs.
