The purpose of this clinical trial is to determine the safety and efficacy of scopolamine utilized in conjunction with naltrexone for the treatment of major depression.
The study will be a double blinded, randomized controlled trial. The medications will be administered orally. The sample size will be 40 participants, 20 in the treatment group and 20 in the control group. The study period will be 4 weeks. Eligible participants will have major depression by history for at least 8 weeks, between 18-65 years old, and in generally good health other than depression. The MADRS questionaire will be utilized to determine the response to the medications.

Response to Medications as Assessed by Change in Score on Modified MDRS Scale From Baseline to End of Study Period

The Montgomery-Asberg (MADRS) depression scale will be utilized throughout the study. The scale is scored 0-60, 0 signifying no depression symptoms and 60 signifying very severe depression. A diagnosis of depression will be given to a participant in this study for a MADRS score of 20 or greater. A clinical response to medication will be noted when a participant has a 25% or greater decrease in MADRS score during the trial.
