The primary objective is to demonstrate whether the addition of pipamperone 5 mg twice daily (bd) to citalopram, 40 mg daily in patients suffering from MDD will improve the efficacy of citalopram 40 mg in these patients. Secondary objectives are to demonstrate whether the addition of pipamperone 5 mg twice daily (bd) to citalopram, 40 mg daily in patients suffering from MDD: 1. Will increase the rate of resolution of symptoms with citalopram 40 mg. 2. Show the combined product to be safe and tolerable. Patients are scheduled to receive study medication for eight weeks and a final follow-up check will be carried out 28 days after completing the study.
