- Drug Therapy: Main Components
- Changing the amount of neurotransmitters at the synapse.
- Anti-Depressants
- Depression is thought to be due to insufficient amount of serotonin being produced at the synapse.
- Anti-depressants work by either reducing the rate of re-absorption or by blocking the enzyme that breaks down the neurotransmitters.
- SSRIs work by stopping nerve cells from reabsorbing the serotonin, increasing the amount of serotonin available.
- Anti-Psychotics
- Conventional anti-psychotics are used primarily to combat the positive symptoms of schizophrenia
- These drugs block the action of the neurotransmitter dopamine in the brain by binding to its receptors.
- The atypical anti-psychotics drugs act by only temporarily occupying dopamine receptors and then rapidly dissociating to allow normal dopamine transmission.
- Giving anti-psychotics lower levels of side effects compared to conventional anti-psychotics.
- Anti- Anxiety
- BZs slow down the activity of the central nervous system.
- They do this by enhancing the activity of GABA, a neurotransmitter that is the body's natural form of anxiety relief.
- BBs bind to receptors of the cells of the heart and other parts of the body that are usually stimulated sympathetic arousal.
- The results is a fall in blood pressure, and therefore less stress on the heart. The person then feels calmer and less anxious.
- BZs slow down the activity of the central nervous system.
