To improve patient's tolerability, dose upward titration will be applied to 28, 42 and 56 mg dose groups according to the following schedule:~* Patients to be enrolled to 14 mg dose group will receive 14 mg for 5 consecutive weeks.~* Patients to be enrolled to 28 mg dose group will receive 14 mg in the first week and then 28 mg in the next 5 weeks.~* Patients to be enrolled to 42 mg dose group will receive 14 mg in the first week, 28 mg in the second week and then 42 mg in the next 5 weeks.~* Patients to be enrolled to 56 mg dose group will receive 14 mg in the first week, 28 mg in the second week, 42 mg in the third week and then 56 mg in the next 5 weeks."
