Joe, Dominic and Chris, Thank you for your quick replies. Dominic, you wrote: >>...Will the side effect profile resemble tolcapone and also have the possibility of liver problems? A study of 700 patients who had received entacapone for 6 to 12 months had no evidence of abnormal liver function tests as a result of entacapone administration. Until the product is approved, it is unknown whether liver function tests will be required and monitored by the FDA.<< Thank you for this clarification. I asked a neurologist/speaker the same question and his response was that liver monitoring would not be necessary. I have also read this elsewhere. That's why I was surprised to read that liver function tests might still be necessary.
