    Study Notes

    Drug Sensitization and Withdrawal

    • Sensitization refers to drug craving driven by changes in the brain, specifically receptor upregulation.
    • Drug efficacy is the ability of a drug to activate its specific receptor.
    • Withdrawal symptoms manifest as unpleasant cognitive sensations following drug cessation.

    Types of Adverse Effects

    • Sexual dysfunction can occur with various medications.
    • Anxiety is a common adverse effect.
    • Akathisia results in inner restlessness.
    • Insomnia disrupts sleep patterns.
    • Gastrointestinal upset includes issues like diarrhea and constipation.
    • Headaches and dry mouth are frequent complaints.
    • Anorexia and weight gain can also result from drug use.
    • Somnolence may cause excessive drowsiness.
    • Urinary retention poses difficulties in urination.
    • Orthostatic hypotension leads to drops in blood pressure upon standing.

    Guidelines for Drug Selection

    • Diagnosis and identification of target symptoms are crucial for appropriate treatment.
    • Consider current and recently discontinued medications.
    • Adjusting the dosage of prescribed drugs may be necessary for optimal effects.

    Special Treatment Considerations

    • Geriatric patients are more vulnerable to adverse effects due to slower metabolism.
    • Children have a smaller volume of distribution but faster metabolism rates.
    • Pregnant and nursing women face risks from teratogenic drugs like lithium and anticonvulsants, which can cause birth defects.
    • Folic acid can reduce teratogenicity risks.
    • Patients with hepatic or renal insufficiency may need reduced dosages to avoid toxicity.

    Drug Administration Routes and Effects

    • Ingestion (tablets, capsules): Slow to moderate speed of effects.
    • Inhalation (smoking, nasal absorption): Moderate to fast onset.
    • Peripheral injection (subcutaneous, intramuscular): Moderate to very fast effects.
    • Central injection (intracerebroventricular, intrathecal): Fast to very fast outcomes.

    Changes in Drug Use in Society

    • Continued high death rates from hepatitis C liver diseases and opioid overdoses.
    • Youth are more susceptible to drug use than adults.
    • Drug abuse treatment centers reported over 5,500 total admissions in recent records, with an increase in methamphetamine cases.
    • Demographics show a majority of users are male, single, and aged 35 on average.
    • Accessibility of drugs has increased due to shorter supply chains facilitated by digital interconnectivity.

    Drug Types and Psychedelic Substances

    • Drug types include natural and synthetic variations.
    • Emergence of new psychoactive substances has been noted.
    • Ongoing research explores the foundation of addiction, highlighting genetic and environmental interactions in susceptibility.

    Understanding Pharmacology and Neurotransmitters

    • Pharmacology studies drug actions and effects on living organisms.
    • The synapse is crucial for communication between neurons, preventing overexcitation in the brain.
    • Key neurotransmitters include glutamate, which is an excitatory neurotransmitter central to CNS function, and acetylcholine, notable for its role across the nervous system and as the first discovered neurotransmitter.

    Perspectives on Addiction

    • Evolving definitions of addiction reflect complex influences—cultural, psychological, social, and biological.
    • Current debates center on the differentiation of addiction vs. dependence and views on treatment versus punishment.
