Pathological gambling is a disorder, the prevalence of which has been increasing continuously and it cannot be diagnosed easily. It can also be treatment resistant and restricts the individual's life increasingly. In studies related to pharmacological treatment of pathological gambling, SSRIs, mood stabilizers, antipsychotics and naltrexone have been used.
