Subjects with concurrent inflammatory diseases including rheumatic disease, rheumatoid arthritis and inflammatory arthritis; hypothyroidism, hyperparathyroidism, autoimmune disease or unstable metabolic disease.
Subjects with current or recent history of psychosis, hypomania, mania, dementia or other serious psychiatric disorder which, in the opinion of the investigator, would make then unsuitable to participate in the study.

Subjects who are intolerant to serotonin and noradrenaline reuptake inhibitors (SNRIs) or nefopam.

Subjects with a history of glaucoma or urinary retention.
Subjects with serum creatinine >1.5 x upper limit of normal [ULN] or liver function tests > 3 x ULN or other abnormal laboratory values at screening which indicates an underlying unknown concomitant disease that requires further evaluation.
