1. occur when
   1. enough cell become functional
   2. enough cell dies and loss function
2. due to
   1. autoimmue
   2. viruses
   3. chemicals
   4. environment,pollution
   5. drugs

1. Therapeutics
   1. use of drugs
      1. diagnose
      2. prevent and illness
2. Pharmacology
   1. study of drugs and interaction with living system
3. Clinical Pharmacology
   1. study of drugs in human
4. Drugs
   1. any chemical that effect living processes
   2. properties of ideal drugs
      1. effectiveness
         1. most important properties
      2. safety
         1. pharmakon = poison in Greek
         2. safe at high conc. & for long periods administration
      3. selectivity
         1. elicits only the response
         2. selective for specific reaction with no side effects
            1. ( there is no such thing )
         3. example
            1. anti histamines = drowsiness
            2. oral contaceptives = morning sickness,cramps,depresion

               2. intravenous infusion
      4. freedom from drug interactions
         1. not augmented or decrease action of drugs
      5. chemical stability
         1. no lose of effectivenesss with storage
      6. low cost
         1. easy to afford ( chronic illness )
            1. lifelong medication

      1. avoid deficiency

1. best medical treatment under the present circumstances
2. best from the viewpoint of the patient and society

         3. adverse reaction
         4. price

1. any drug not over the counter requires a prescription
2. 4 basic parts
   1. superscription
   2. inscription
   3. subsription
   4. signature
3. patients education about OTC drugs
   1. give attention whether patients is taking prescription or OTC
