    Study Notes

    Parasympathetic Nervous System Enhancers

    • Parasympathomimetics are drugs that stimulate the parasympathetic nervous system (PSNS).
    • Neurotransmitter effects mimicked by parasympathomimetics primarily involve acetylcholine.

    Relationship Between PSNS and SNS

    • The PSNS and sympathetic nervous system (SNS) work antagonistically: PSNS promotes rest and digestion, while SNS prepares the body for "fight or flight" responses.

    SLUDGE Acronym

    • SLUDGE stands for:
      • Salivation
      • Lacrimation
      • Urination
      • Diarrhea
      • Gastrointestinal distress
      • Emesis (vomiting).
    • The 'D' in SLUDGE specifically refers to Diarrhea.

    Symptoms and Conditions

    • Early signs of certain conditions may exclude non-specific symptoms; details about what is or isn't included would need clarification.
    • Signs of circulatory collapse may include hypotension, tachycardia, and altered mental status.
    • Transient syncope refers to a temporary loss of consciousness typically due to a drop in blood flow to the brain.

    Drug Dependence

    • Tolerance indicates reduced response to a drug after repeated use, requiring higher doses for the same effect.
    • Physical dependence involves withdrawal symptoms when the drug is not taken, while psychological dependence is characterized by cravings without the physiological symptoms.
    • An alternative term for psychological dependence is addiction.
