The mechanism by which they interact, and how antidepressant medications work to enhance these interactions is simple, yet elegant, as illustrated in the picture below:. Some of these transmitters then travel across the synapse and bind onto receptors of the next brain cell the postsynaptic neuron , which can then cause that cell to fire as illustrated in pathway 1 in the picture above. If the neurotransmitter levels are low in depression, it makes sense to block the reuptake, or block the enzymes that degrade them, to increase their numbers in the synapse, thereby increasing the likelihood that they will bind to the next brain cell.
A different antidepressant, Wellbutrin Bupropion , inhibits the reuptake of dopamine. Another class of antidepressants works to boost both serotonin and nor-epinephrine. These work by blocking the enzyme MAO monoamine oxidase that breaks down the neurotransmitters, but these are not widely used because they interact with many foods and drugs. Successfully treating the symptoms of depression with an antidepressant is both an art and a science, and the choice of antidepressant can depend upon a variety of factors.
Family history of response to a particular medication among genetically-related family members can be a helpful predictor, as can the presence of certain symptoms to target, which are known to respond to increases in one or more of the neurotransmitters noted above.
Social anxiety and obsessive—compulsive disorder symptoms may respond to SRIs and also be worsened by Wellbutrin. In patients with depression, social anxiety, and ADHD, an SNRI may be helpful by boosting both serotonin and norepinephrine to address their broad spectrum of symptoms.
Antidepressant augmenters include Folic Acid a B vitamin , Omega 3 fish oil, thyroid hormone, testosterone, lithium, a second antidepressant from a different class e.
Abilify , and N-Acetylcysteine. The use of each of these augmenters may have a different rationale — for example Abilify may be used in the depressed patient struggling with many negative thoughts or mood instability — while Wellbutrin could be used to boost the energy level of a patient who has partially responded to an SRI, but continues to suffer from a lack of motivation and drive. In the more treatment-resistant patient, multiple augmenters may be used. Sometimes medications will be combined to boost all three neurotransmitters — for example using both Cymbalta and Wellbutrin — in certain patients with a treatment resistant depression that is not responding to the methods described above.
Our knowledge of antidepressant treatment continues to advance. While researchers in some circles doubt the effectiveness of antidepressant medications, my experience over the years is that the efficacy of antidepressants is unequivocal.
Responses to these medications range from enhanced self esteem and improved quality of life for those patients who are mildly to moderately depressed, to restoring basic daily functionality and providing lifesaving benefits for those who are moderately to severely depressed.
This is called monotherapy. If that happens, they might try another medication within that class, or switch to another class of antidepressants entirely. Research now suggests that taking antidepressants from multiple classes may be the best way to treat MDD.
In fact, bupropion is one of the most commonly used combination therapy medications. For people experiencing loss of appetite and insomnia, mirtazapine may be an option. Its most common side effects are weight gain and sedation.
Research suggests there may be some benefit in treating persistent symptoms in people taking SSRIs with atypical antipsychotics, such as aripiprazole. Carefully consider the pros and cons of antipsychotics with your doctor. Their side effects may prolong or worsen some symptoms of depression. Research suggests that T3 with a TCA may lead to a faster response to treatment compared with taking a TCA alone, but more research is needed.
The dose typically used for this purpose is 25 micrograms mcg a day of triiodothyronine. D-amphetamine Dexedrine and methylphenidate Ritalin are stimulants used to treat depression. They can be used alone, but they may also be used in combination with antidepressant medications. Stimulants are most helpful when the desired effect is a quick response.
People with severe depression symptoms or other conditions, such as chronic illnesses, may be good candidates for this combination. Success rates of monotherapy treatment are relatively low. Therefore, many researchers and doctors believe the first and best approach to treating MDD is combination treatments. Despite the name, there are still treatments that can…. Researchers have studied numerous herbs, supplements, and vitamins to determine if they can benefit people with depression.
