Study Notes
CNS Pharmacology Overview
- The central nervous system (CNS) is the primary target of psychopharmacological agents.
- CNS pharmacology deals with the study of drugs that affect the brain and spinal cord.
Mechanisms of Action
- Neurotransmission: Drugs can modify the release, uptake, or degradation of neurotransmitters.
- Receptor binding: Drugs can bind to specific receptors, altering their activity.
- Ion channel modulation: Drugs can affect the flow of ions across the neuronal membrane.
Classes of CNS Drugs
- Anxiolytics: Reduce anxiety and fear responses (e.g., benzodiazepines).
- Antidepressants: Treat depression and other mood disorders (e.g., SSRIs, MAOIs).
- Antipsychotics: Treat psychosis and schizophrenia (e.g., dopamine antagonists).
- Hypnotics: Induce sleep (e.g., benzodiazepines, zolpidem).
- Stimulants: Enhance alertness and attention (e.g., amphetamines, methylphenidate).
- Narcotics: Treat pain and cough (e.g., opioids).
Neurotransmitters and Their Roles
- Acetylcholine: Involved in memory, attention, and muscle contraction.
- Dopamine: Regulates movement, reward, and motivation.
- GABA: Inhibitory neurotransmitter, reducing neuronal activity.
- Glutamate: Excitatory neurotransmitter, increasing neuronal activity.
- Norepinephrine: Involved in attention, arousal, and sympathetic nervous system activity.
- Serotonin: Regulates mood, appetite, and sleep.
CNS Pharmacology and Therapeutic Uses
- Pain management: Opioids and other analgesics for pain relief.
- Sleep disorders: Hypnotics and sedatives for insomnia and other sleep disorders.
- Mood disorders: Antidepressants and mood stabilizers for depression and bipolar disorder.
- Psychotic disorders: Antipsychotics for schizophrenia and other psychotic disorders.
- Anxiety disorders: Anxiolytics for anxiety and panic disorders.
Adverse Effects and Contraindications
- CNS depression: Respiratory depression, sedation, and coma.
- Dependence and addiction: Physical and psychological dependence on CNS drugs.
- Interactions: Drug-drug interactions, especially with other CNS drugs.
- Contraindications: Certain medical conditions, such as glaucoma, or pregnancy and lactation.
