Summary
This trial is testing whether fluoxetine, a common depression medication, is safe and effective for adults with Down syndrome. The study will last several months, with doses adjusted initially and then kept stable towards the end. Researchers will monitor side effects and measure depression levels throughout the study. Fluoxetine, commonly known as Prozac, has been widely studied and used for treating major depression since its introduction.
Who is the study for?
Adults aged 18-45 with Down syndrome and moderate to severe depression, confirmed by specific clinical assessments, can join this trial. They must not have any conditions that make fluoxetine unsafe like allergies to it, liver/kidney disease, unstable heart disease or be pregnant without contraception. Participants should not be on certain antidepressants or psychotropic drugs before the trial.
What is being tested?
The study is testing if fluoxetine is an effective and safe treatment for adults with Down syndrome who are experiencing depression. It's a preliminary assessment focusing on the drug's impact on depressive symptoms in this particular group.
What are the potential side effects?
Fluoxetine may cause side effects such as headaches, nausea, sleepiness or insomnia, nervousness, dry mouth and sexual problems. In some cases it might also lead to more serious issues like allergic reactions or changes in mood.

Other Research
Selective Serotonin Reuptake Inhibitors (SSRIs), such as Fluoxetine, function by increasing serotonin levels in the brain through the inhibition of its reuptake into neurons. This mechanism is particularly important for Down Syndrome patients as serotonin plays a crucial role in mood regulation, cognitive function, and overall brain health.
By enhancing serotonin levels, SSRIs can potentially improve mood, reduce anxiety, and enhance cognitive abilities, addressing common challenges faced by individuals with Down Syndrome.
