3. Patients who experience pain associated with diabetic peripheral neuropathy and having visual analogue scale (VAS) score more than or equal to 30 at screening and baseline visit.
4. Patients with decreased vitamin B12 levels (less than 200 pg per mL) at screening visit.
5. Women of childbearing potential (WOCBP) must be using an acceptable method of contraception to avoid pregnancy throughout the study. WOCBP must have a negative urine pregnancy test at screening or baseline visit.

3. Patients who are experiencing non-diabetic peripheral neuropathy-related pain.
4. Patients with clinically significant impaired hepatic function (SGOT & SGPT more than 3X the UNL and or Total bilirubin more than 1.5X the UNL) at screening.
5. Patients with clinically significant impaired renal function (Serum creatinine more than 1.5X the ULN) at screening.
6. Patients having serum sodium level less than 130 mmol per L at screening.
7. Patients with history of type 1 diabetes mellitus.
8. Patients with uncontrolled hypertension with sitting systolic BP more than or equal to 160 mmHg and or diastolic BP more than or equal to 100 mmHg at screening.
9. Patients with any abnormality on 12-lead ECG at screening that in the opinion of the investigator is clinically significant and is judged as potential risk for patient’s participation in the study.
10. Patients with history of suicidal thoughts and behavior.

13. Patient treated with topical or systemic pain medications (e.g., NSAIDs, local anesthetics, Methyl Salicylate, Capsaicin, Tramadol, Tapentadol etc.) within past 2 weeks prior to baseline.
14. Female patients who are pregnant or breast-feeding or expecting to conceive within the projected duration of the study.
