Questions and Answers

What is the concept of toxicity?

  • The therapeutic use of drugs in treating toxicity
  • The study of the adverse effects of drugs on the body (correct)
  • The mechanism of action of drugs in the body
  • The process of drug absorption in the body

    • What are the advantages and disadvantages of the Parenteral route?

  • Long duration of action, minimal tissue damage
  • Ease of administration, slow onset of action
  • High patient compliance, limited drug absorption
  • Rapid drug absorption, risk of infection (correct)

    • What is the difference between histamine and anti histamine?

  • Histamine is an enzyme, while anti histamine is a receptor
  • Histamine is a bronchodilator, while anti histamine is a bronchoconstrictor
  • Histamine causes allergic reactions, while anti histamine treats allergies (correct)
  • Histamine is a neurotransmitter, while anti histamine is a hormone

    Study Notes

    Pharmacology Concepts

    • Toxicity: The degree to which a substance can cause harm or damage to living organisms, including humans.

    Routes of Administration

    • Parenteral Route: A method of administering drugs through injection, avoiding the gastrointestinal tract, and allowing for faster absorption.
    • Advantages of Parenteral Route:
      • Rapid onset of action
      • Higher bioavailability
      • Suitable for emergency situations
    • Disadvantages of Parenteral Route:
      • Invasive and painful
      • Risk of infection and allergic reactions
      • Requires specialized training and equipment

    Histamine and Anti-Histamine

    • Histamine: A neurotransmitter involved in local immune responses, regulating physiological functions such as sleep, appetite, and blood pressure.
    • Anti-Histamine: A medication that counteracts the effects of histamine, used to treat allergies, itching, and other conditions.

    Neurotransmitters

    • Neurotransmitter: A chemical messenger that transmits signals between neurons in the nervous system, influencing various physiological and psychological processes.

    Treatment of Diarrhea

    • Prototype Drugs: Medications that serve as a model for treating a specific condition, in this case, diarrhea.
    • Examples of prototype drugs used to treat diarrhea:
      • Loperamide (Imodium)
      • Diphenoxylate (Lomotil)
