    INORGANIC COMPOUNDS
                         th
      Berzelius, the 19   century chemist , 
      described inorganic compounds are 
      inanimate.
    
      The first important synthetic inorganic 
      compound was ammonium nitrate for soil 
      fertilization.
    
      These are synthesized for use as drugs such 
      as cisplatin, magnesium hydroxide etc.
    
      Some of the compounds are used as  
      catalysts and reagents in organic chemistry. 
      Ex: lithium aluminium hydride.
  Sources of inorganic compounds :
  
   Derived from either organic or inorganic sources .
  
   Many drugs are from plant and synthetic  sources.
     Definition :
      Study of pharmaceutical applications of the 
  inorganic compounds led to the establishment  of a 
  new avenue called pharmaceutical inorganic 
  chemistry.
  It deals with the study  of  preparation, standards 
   of purity, limit test for determining quality ,purity 
   and storage conditions of all inorganic compounds.
  Importance of inorganic pharmaceuticals :
  Inorganic pharmaceuticals are useful in the 
  following ways :
  
   Useful medicinally for their therapeutic 
   purpose . Ex: Astringents and antimicrobials 
   etc.
  
   Pharmaceutical aids. Ex: Bentonite , talc etc.
  
   Replenishing the normal content  of  body 
   fluids. Ex- Sodium, potassium, calcium, 
   chloride etc.
  
   Used in pharmaceutical analysis . Ex – 
   Titrants such as  potassium permanganate 
   etc.
  Applications in pharmacy as follows :
  
   Abrasives – Dibasic calcium phosphate .
  
   Absorbents – Calcium carbonate .
  
   Acidifiers – dil. Hydrochloric acid .
  
   Adsorbents – Bismuth subnitrate .
  
   Alkalizers  - Sodium citrate .
  
   Anaesthetics – Nitrous oxide .
  
   Analgesic – Nitrous oxide .
  
   Antacids – Caco3 .
  
   Anthelmintics – Ammoniated mercury.
