Post-Marketing Surveillance Study on the Safety and Efficacy of Cymbalta (Duloxetine) on Diabetic Peripheral Neuropathic Pain Among Filipino Patients

Study Overview
=================
Brief Summary
-----------------
Primary objective: To estimate the frequency of adverse events, serious and non-serious in Filipino patients with diabetic peripheral neuropathic pain treated with duloxetine 60mg once daily within the study duration of approximately 6-8 weeks in a naturalistic clinical setting. Secondary objective: To evaluate the change from baseline to endpoint in the Brief Pain Inventory (BPI) and Neuropathic Pain Questionnaire (NPQ) assessed by the investigators in duloxetine use in the treatment of diabetic peripheral neuropathic pain among Filipino patients within the study duration of approximately 6-8 weeks in a naturalistic clinical setting.
