Chapter 23 Drugs as Medicines
  • How have drugs significantly affected the lives of Americans?
  • Drugs make our world a better place.
  • Today is a time for QUICK CURES.

Medicines are classified into 4 Broad Categories


  • Prevent Disease
  • Fight Pathogens (microorganisms that enter the body and attack its cells and tissues)
  • Relieve Pain
  • Helps the heart regulate blood pressure
drugs that fight
Drugs that Fight
  • Antibiotic –
    • drug that microscopic organisms produce (penicillin and tetracycline)
  • Penicillin – Penicillin Video
    • antibiotics that kills a wide variety of bacteria
  • Tetracycline –
    • antibiotics used to treat infections
  • Topical antibiotics –
    • treats minor cuts, burns and abrasions
  • Sulfa Drugs –

  • Vaccines – preparation, containing weakened or dead pathogens that cause a particular disease. It is given to prevent one from contracting that particular disease.
  • Antibody – a protein substance in the blood that acts against poisons or the bacteria that produces them
  • Antisera – body fluids that contain antibodies and act more quickly than vaccines
drugs that affect the heart and regulate blood pressure

  • ****Most widely used and abused drugs? WHY?

  • Analgesic– relieves and stops pain
  • Antidepressants – relieves emotional depression
  • Stimulants– prevent sleep, reduce distractibility in hyperactive children and suppress appetite

  • Tranquilizers – relieve anxiety and tension (hypnotics) as well as to relieve insomnia due to the anxiety and tension.
  • A 7th group is called Hallucinogens, but it requires special identification. This group alters consciousness and there is no generally accepted medical use.


    • May contain aspirin and can further stomach irritation.
      • Prevention – eat slowly, chew food well, do not over eat, avoid foods that irritate your stomach.
  • Antihistamines – cold remedies
  • What is the major problem with liquid cold remedies?
  • Correct measurement, ½ of adult dosage for children, weight difference
medicines in the body
Medicines in the Body
  • Side Effects – a reaction other than the one intended.
  • Additive Interaction – medicines work together in a positive way.
    • Example/ Anti-inflammatory + muscle relaxant to treat joint pain
  • Synergistic Effect – the interaction of two or more medicines that results in a greater effect than when the medicines are taken independently.
  • Antagonistic Interaction – the effect of a medicine is cancelled or reduced when taken with another medicine.
    • Example/ Anti-rejection meds. (transplants) and insulin. Insulin may be decreased.
  • Tolerance – body becomes use to the effect
  • Withdrawal – when a person stops using a medicine or other substance to which he or she has a physiological dependence.
    • Examples of symptoms – nervousness, insomnia, severe nausea, headaches, vomiting, chills, and cramps
effects of the drug in the body depends on
Effects of the drug in the body depends on:
  • Type of drug taken
  • Method by which the drug was taken
    • Swallowed – starts to dissolve in stomach before going into the bloodstream (absorbed through the walls to the bloodstream)
      • Liver processes all food and chemicals so to be used or eliminated
    • Intravenously (in the veins) or Intramuscularly (in the muscle)
      • Injection causes immediate entrance into the bloodstream and then to the liver.
drugs interact not only with one another but with food as well
Drugs interact not only with one another but with food as well.
  • Presence of food:
    • In the digestive system can slow down or speed up the time it takes a drug to go through the digestive tract to the site in the body where it is needed.
    • Take on an empty stomach or just before meals or with meals.
    • Can contain natural and sometimes added chemicals (reaction can be severe)
    • Can speed up absorption but more often interferes with it.
    • Example:
      • Tetracycline with dairy products (calcium in milk and cheese), impairs the body’s capacity to absorb the antibiotic.
      • Acidity in soft drinks and fruit juices causes some drugs to dissolve quickly in the stomach instead of intestines, where they will be readily available.
