Study Notes
Stimulants
-
Effects On The Nervous System:
- Increase levels of dopamine and norepinephrine.
- Boost alertness, attention, and energy.
- Can elevate heart rate and blood pressure.
-
Addiction Potential:
- High potential for addiction due to rapid reinforcement.
- Risk of tolerance, leading to increased dosages.
-
Medical Uses:
- Treatment of Attention Deficit Hyperactivity Disorder (ADHD) (e.g., Adderall, Ritalin).
- Certain antidepressants (e.g., bupropion).
-
Legal Status And Regulations:
- Many are classified as Schedule II substances in the U.S.
- Legal for medical use with prescription; illegal use is criminalized.
-
Withdrawal Symptoms:
- Fatigue, depression, irritability.
- Increased appetite, sleep disturbances.
Depressants
-
Effects On The Nervous System:
- Reduce neuronal activity and decrease brain function.
- Induce relaxation, sedation, and decreased anxiety.
-
Addiction Potential:
- Moderate to high potential for addiction.
- Risk of developing tolerance and dependency.
-
Medical Uses:
- Treatment of anxiety and sleep disorders (e.g., benzodiazepines, barbiturates).
- Anesthesia (e.g., propofol).
-
Legal Status And Regulations:
- Many are Schedule IV substances (e.g., benzodiazepines) in the U.S.
- Legally prescribed for medical conditions, but regulated.
-
Withdrawal Symptoms:
- Anxiety, insomnia, tremors.
- Severe cases may lead to seizures or delirium.
Inhalants
-
Effects On The Nervous System:
- Rapidly depress the central nervous system.
- Can cause euphoria, dizziness, and hallucinations.
-
Addiction Potential:
- Moderate addiction potential; users can develop a tolerance.
- Risk of psychological dependence.
-
Medical Uses:
- Some are used medically as anesthetics (e.g., nitrous oxide).
- Limited approved usage due to safety concerns.
-
Legal Status And Regulations:
- Many inhalants are legal household products; misuse is illegal.
- Regulations focus on preventing abuse rather than outright bans.
-
Withdrawal Symptoms:
- Irritability, insomnia, cravings.
- In severe cases, withdrawal can lead to neurological symptoms.
Stimulants
- Increase dopamine and norepinephrine levels in the brain.
- Boost alertness, attention, and energy.
- Elevate heart rate and blood pressure.
- High potential for addiction.
- Risk of developing tolerance, leading to increased dosages.
- Used to treat ADHD and as certain antidepressants.
- Many are classified as Schedule II substances in the U.S.
- Legal for medical use with prescription, but illegal use is criminalized.
- Withdrawal symptoms include fatigue, depression, irritability, increased appetite, and sleep disturbances.
Depressants
- Reduce neuronal activity and decrease brain function.
- Induce relaxation, sedation, and decreased anxiety.
- Moderate to high potential for addiction.
- Risk of developing tolerance and dependency.
- Used to treat anxiety and sleep disorders, and as anesthetics.
- Many are Schedule IV substances in the U.S.
- Legally prescribed for medical conditions, but regulated.
- Withdrawal symptoms include anxiety, insomnia, tremors, and in severe cases seizures or delirium.
Inhalants
- Rapidly depress the central nervous system.
- Can cause euphoria, dizziness, and hallucinations.
- Moderate addiction potential.
- Risk of psychological dependence.
- Some are used medically as anesthetics.
- Limited approved usage due to safety concerns.
- Many are legal household products, but misuse is illegal.
- Regulations focus on preventing abuse rather than outright bans.
- Withdrawal symptoms include irritability, insomnia, cravings, and in severe cases neurological symptoms.
Stimulants
- Increase neurotransmitter activity, including dopamine and norepinephrine.
- Enhance alertness, energy, and focus.
- Stimulants can elevate heart rate and blood pressure.
- High potential for dependence and addiction, exemplified by cocaine and amphetamines.
- Tolerance develops, increasing required dosage to achieve the desired effect.
- Medical applications include treating ADHD with medications like methylphenidate and amphetamines.
- Stimulants have anorectic properties, suppressing appetite.
- Withdrawal symptoms manifest as fatigue, depression, and increased appetite.
- Intense cravings for the substance characterize withdrawal.
- Classified as Schedule II controlled substances in many jurisdictions, necessitating stringent prescription and distribution regulations.
Depressants
- Depressants reduce brain activity, inducing sedation and relaxation.
- Inhibition of neurotransmitters, particularly GABA, contributes to reduced anxiety.
- Moderate to high potential for abuse, as seen with benzodiazepines and alcohol.
- Dependence can manifest physically and psychologically.
- Medical uses include treating anxiety, insomnia, and seizures.
- Anesthesia during surgical procedures relies on depressants.
- Withdrawal symptoms encompass anxiety, insomnia, seizures, and tremors.
- In severe cases, delirium, especially during alcohol withdrawal, can occur.
- Generally legal, though most require prescriptions.
- In the United States, benzodiazepines are classified as Schedule IV controlled substances.
Inhalants
- Inhalants produce short-term euphoria due to rapid delivery of chemicals to the brain.
- Effects include dizziness, impaired judgment, and altered sensory perception.
- Dependence potential ranges from low to moderate, often leading to habitual use.
- The intense yet ephemeral high can encourage repeated use.
- Limited medical uses exist, such as anesthetics or specific medical procedures.
- Some formulations, like nitrous oxide, find medical applications.
- Withdrawal symptoms include headaches, nausea, and irritability.
- Cravings and withdrawal effects are less prevalent compared to stimulants and depressants.
- Generally legal for household use; however, specific substances have restrictions.
- Substance abuse laws primarily focus on inhalant misuse rather than legal use.
Antidepressants
- Function: Treat depression, anxiety, and some personality disorders
-
Classes:
- SSRIs (Selective Serotonin Reuptake Inhibitors): Increase serotonin levels in the brain (e.g., fluoxetine, sertraline)
- SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors): Increase serotonin and norepinephrine levels (e.g., venlafaxine, duloxetine)
- Tricyclic Antidepressants (TCAs): Block the reuptake of serotonin and norepinephrine (e.g., amitriptyline, nortriptyline)
- MAOIs (Monoamine Oxidase Inhibitors): Inhibit the breakdown of neurotransmitters, increasing their levels (e.g., phenelzine, tranylcypromine)
Antipsychotics
- Function: Manage psychosis, including schizophrenia, bipolar disorder, and severe depression with psychotic features
-
Types:
- Typical Antipsychotics: Block dopamine receptors (e.g., haloperidol, chlorpromazine)
- Atypical Antipsychotics: Act on a broader range of receptors, including serotonin and dopamine (e.g., risperidone, olanzapine)
Side Effects
-
Antidepressants:
- Common: Nausea, weight gain, insomnia, sexual dysfunction
- Rare: Increased suicidal thoughts in adolescents
-
Antipsychotics:
- Typical: Extrapyramidal symptoms (tremors, rigidity), tardive dyskinesia, sedation
- Atypical: Metabolic syndrome (weight gain, diabetes risk), agranulocytosis (low white blood cell count)
Psychopharmacology
- Definition: The study of how medications affect mood, behavior, and mental state.
-
Goals:
- Symptom relief: Achieve remission of mental disorder symptoms
- Improve quality of life: Enhance overall functioning and well-being
- Maintenance therapy: Long-term treatment to prevent relapse in chronic conditions
-
Considerations:
- Genetic factors: Response to medications can vary based on genetics
- Integrated treatment: Combining medications with psychotherapy often leads to better outcomes
