Primary Outcome Measures:
- Statistically Significant (p<0.05) Decrease From Baseline in Yale Brown Obsessive Compulsive Scale Modified for Pathological Gambling [ Time Frame: Baseline and 6 weeks ]This scale assesses the severity of gambling urges and gambling behaviors. The study anticipates that there will be a reduction in either or both of these assessments. The range is from a minimum of 0 to a maximum of 40, where zero means no gambling urges occurred.
Secondary Outcome Measures:
- Type, Frequency and Severity of Side Effects [ Time Frame: 6 weeks ]All side effects of the drug will be monitored and recorded
- Statistically Significant Changes in the Gambling Symptom Assessment Scale [ Time Frame: 6 weeks ]It is expected that there will be decreases in this scale
- Effects on the Clinical Global Impression [ Time Frame: 6 weeks ]Clinician's Global Impression is used assess severity and changes in clinical symptoms during and at the end of the study

Detailed Description:
The purpose of this study is to determine if ecopipam is able to stop urges to gamble in patients diagnosed with Pathological Gambling. Nerves communicate with each other by releasing chemicals called "neurotransmitters". One of these neurotransmitters in the brain is called "dopamine". After dopamine is released by the nerve it "talks" to other nerves by interacting with receptors that are unique to that neurotransmitter. Ecopipam is a drug that selectively blocks one family of dopamine receptors. Some scientists believe that the urge to gamble is related to having too much dopamine in the brain. By blocking the receptors that dopamine uses, ecopipam may be able to relieve the urge to gamble.
