I havent seen details of the trial. Did they control for variables while assessing its therapeutic analgesic ability. Which patients were already on narcotics, paracetamol and NSAIDS?? Did any patients have any evidence of a peripheral neuropathy or other co-morbidities?
And is it better than panadol? Would it be more expensive to produce and sell relative to panadol?
I think its quiet difficult to find a pharma who would take this on.
Im not trying to be negative but just realistic...
