Mood Stabilizers (Anticonvulsants)
They decrease neuronal excitability and are used for bipolar disorder, seizure disorders, and sometimes neuropathic pain.
Cholinesterase Inhibitors
They inhibit the enzyme acetylcholinesterase, which leads to increased acetylcholine in the brain, and are used to treat Alzheimer's disease.
SNRIs
Serotonin-Norepinephrine Reuptake Inhibitors elevate serotonin and norepinephrine levels, treating major depressive disorder, anxiety, and sometimes chronic pain.
NMDA Receptor Antagonists (Memantine)
They block NMDA glutamate receptors and are used in the management of Alzheimer's disease to slow down progression.
Second-Generation Antidepressants
They have various mechanisms including SSRI, SNRI, and others, and they treat depression, with generally fewer side effects compared to older antidepressants.
Typical Antipsychotics
They primarily block D2 dopamine receptors and are used to treat schizophrenia but can cause extrapyramidal symptoms.
Naltrexone for Alcohol Dependence
It blocks opioid receptors, reducing the rewarding effects of alcohol, and is used as part of the treatment for alcohol dependence.
SSRIs
Selective Serotonin Reuptake Inhibitors increase serotonin levels in the brain and are used to treat depression and anxiety.
Lithium
Lithium modulates neurotransmitter release and supports neuroplasticity, used primarily in the management of bipolar disorder.
TCA (Tricyclic Antidepressants)
They inhibit the reuptake of norepinephrine and serotonin, treating depression, chronic pain, and sometimes insomnia.
Beta-Blockers for Anxiety
They block the effects of adrenaline on beta receptors, thus reducing physical symptoms of anxiety such as tachycardia and tremors.
Stimulants
They increase dopamine and norepinephrine activity, used mainly to treat Attention Deficit Hyperactivity Disorder (ADHD) and narcolepsy.
MAOIs
Monoamine Oxidase Inhibitors prevent the breakdown of monoamine neurotransmitters, treating depression and anxiety, but have dietary restrictions due to potential hypertensive crisis.
Benzodiazepines
They enhance the effect of the neurotransmitter GABA and are used for anxiety disorders, insomnia, seizures, and alcohol withdrawal.
Atypical Antipsychotics
They block dopamine D2 receptors and serotonin receptors, treating schizophrenia, bipolar disorder, and depression augmentation.
