  • Origins     In earliest times, medicine was based in magic and religion. Sumerians living around 4,000 BC believed that demons were the cause of illness. In many cultures, physicians were priests, and sometimes considered as gods. E.g. Imhotep (born 3,000 BC) became the Egyptian god of medicine. View slide
  • Ancient Origins • Hippocrates - Proposed that disease came from natural, not supernatural causes. • Established the theory of humors which needed to be imbalanced for good health (blood, phlegm, black bile, yellow bile). • Beyond Hippocrates - an approach to medicine in which natural causes were examined scientifically, gradually grew to become the dominant approach to treating human illness.
  • Natural Medicine   Besides looking to the supernatural, ancient man also looked to the natural world for medical answers. Sources of Drugs - Drugs come from various sources and can be classified as:  Natural.  Synthetic: created artificially.  Synthesized: (created artificially but in imitation of naturally occurring substances).  Semisynthetic: (containing both natural and synthetic components).
  • A Treatment for Malaria     One of the most deadly disease in world’s history. Still deadly in developing countries. The first medicine was obtained from the Bark of a Peruvian Tree. Cinchona – Quinine  Also called “Jesuite’s powder.”
  • Cocaine, the First Anesthetic (numbing agent)     The Indians of the Andes used to chew coca leaves for its medicinal effects and also to increase endurance. Cocaine is the active ingredient in the leaves. Carl Koller, a Viennese surgeon in 1884 used it as the first local anesthetic which revolutionized surgery and dentistry. Because of its harmful properties when abused, other synthetic substitutes were procain (Novacain®) and Lidocain.
  • Natural Aspirin      The ancient Greek physician Hippocrates and Dioscorides both wrote about the pain relieving ability of a plant. The bark of a white willow tree grew in the Mediterranean. The active ingredient was identified more than 2,000 years later and called salicylic acid. Because of the difficulty of taking salicylic acid by mouth, acetylsalicylic acid, popularly known as aspirin, was developed synthetically (man-made). It is the most widely used drug in the world.
  • Common Terms Used in Pharmacy       Pharmacology -The study of drugs (from the Greek pharmakon means drug). Pharmacognosy - The study of physical, chemical, biochemical and biological properties of drugs as well as drugs from natural sources. Pharmacopeia – An official listing of drugs and issues related to their use. Pharmaceutical – Of or about drugs; also, a drug product. Panacea – A cure-all (from the Greek panakeia). Materia Medica – A dictionary of medicinal plants.
  • Dioscorides (First century)     Wrote the first standard text/manual on drugs called De Materia Medica. Also called PHARMACOPOEIA. Published 6 books that covered over 600 plants and their healing properties. His book was used for 1500 years.
  • Galen (Second century)   Galen  Conducted animal experiments.  Produced a systematic classification of drugs for treatment of disease. Galenical pharmacy  The first pharmacy .  Described the process of creating extracts of active medicinals from plants.
  • Foxglove – the First Heart Medicine    The British Physician, William Withering published his study of the foxglove plant. The active ingredient was digitalis.  Widely used for heart failure.  Now is called – digoxin. Former President Bush was on digoxin for a racing heart called atrial fibrillation.
  • Ancient Origins • • • • Boylston (18th Century) - The first person to administer smallpox vaccine. Serturner (19th Century) - Extracts morphine from opium. Pasteur (19the Century) - was the first scientist who Showed that heat can be used to kill microorganisms associated with food spoilage. Banting & Best (20th Century) - Show that insulin lowers blood sugar in dogs and became a known drug to treat diabetes.
  • The First Antibiotic - Penicillin     Alexander Fleming discovered a fungus which produces a chemical that kills bacteria. He named it penicillin. Penicillin was the first antibiotic drug. A pharmaceutical company Pfizer developed a method to mass produce it, and it was used to save millions of lives during the World War era.
  • Ancient Origins • 1950’s • Watson and Crick: are the two people who identified the structure of DNA genetic make up. • 1960 – 1990’s • The birth control pill was introduced. • AZT becomes the first drug approved by the FDA for AIDS treatment. • HAART (Highly Active Antiretroviral Therapy) is introduced for AIDS treatment .
  • The 20th Century   The average life span in the United States increased by over twenty years in the 20th Century. 1900 – early 50’s……….. 2000 – 77.9 years.
  • The 20th Century    A major factor in the increased health and life expectancy seen in this century, was the dramatic growth in pharmaceutical medicine. With the increasing availability of powerful drugs, their regulation became more important than ever. Food and Drug Administration (FDA) was established in response to this need to regulate the sale and use of medication in the US.
  • The Food and Drug Administration (FDA)    Monitors drugs before a drug is marketed in the United States Also monitors after the drug is approved for sale to the public for any adverse effects – called Post Marketing Surveillance Recalls drugs if they have proven dangerous within public safety
  • Discovery of New Drugs     Pharmaceutical companies spend 1/6 of their income on research and development. Bringing drugs to market is a long and difficult process. Thousands of chemicals must be tried. Drugs must go through an extensive testing and approval process before it can be made available to the public. The length of time from the beginning of development through testing and to ultimate FDA approval is often more than ten years.
  • OBRA ’90 requires that pharmacist counsel all Medicaid patients.
  • Pharmacy Today   Prescription is a written paper for a drug product by a licensed prescriber to treat a patient. Prescriptions filled increased by 27% while the number of pharmacists increased by 15% (1997 – 2007).
