7. Medicines are classified into 4 Broad Categories Categories: • Prevent Disease • Fight Pathogens (microorganisms that enter the body and attack its cells and tissues) • Relieve Pain • Helps the heart regulate blood pressure

8. 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 – • are germ killers that are made from certain chemical substance (man made)

9. Drugs that Prevent Disease • 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

10. Drugs that affect the HEART and regulate Blood Pressure • 5 Main Kinds • Digitalis – increase the force of contraction in the heart. • Cuts down the number of heartbeats and controls irregular heart beats • Diuretics – helps to relieve the body of water and sodium. (good after heart failure) • Vasodilators – dilate the veins and arteries to increase blood and oxygen flow. • Antiarrhythmics – given in cases of arrhythmia – any disturbance in the rate or rhythm of the heart. • Preventive agents – used to prevent conditions • Ex./ high blood pressure, blood clots, fatty deposits in blood

11. Drugs that affect the Nervous System • ****Most widely used and abused drugs? WHY? • Alters moods and feelings • 6 Major groupings • Analgesic– relieves and stops pain • Antidepressants – relieves emotional depression • Stimulants– prevent sleep, reduce distractibility in hyperactive children and suppress appetite • Hypnotics – give relief to moderate or mild anxiety and tension and aids in sleep • Barbiturates – used for many of the same reasons as hypnotics as well as used to prevent various types of seizures • 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.

12. Antacids • 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

13. 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

14. 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.

15. 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.
