        What is Pharmaceutical 
               Chemistry?
       Pharmaceutical chemistry is the study of drugs, and it 
      involves drug development. This includes drug discovery, 
         delivery, absorption, metabolism, and more.
     .
     Pharmaceutical  chemistry  is  concerned  with  the  design  (drug  design)  and  synthesis  of 
     biologically active molecules. 
     The  aim  is  to  gain  new  chemical  molecules  that  could  enable  the  discovery  of  new 
     pharmaceuticals  or  optimize  already  known  drug  structures,  thereby  to  expand  the 
     portfolio of chemical drugs. 
  Chemistry of acids and bases
  Chemistry is the defining science of pharmacy. 
  To understand anything about a drug; – 
  the synthesis, 
  the determination of its purity, 
  the formulation into a medicine, 
  the dose given, 
  the absorption and distribution around the body, 
  the molecular interaction of drug with its receptor, 
  The metabolism of the drug and, 
  the elimination of drug from the body
  – requires a thorough and comprehensive understanding of the chemical
  structure of the drug and how this chemical structure influences the properties and 
  behaviour of the drug in the body. 
  For these reasons, chemistry is the most important of all the scientific disciplines 
  contributing to the understanding of drugs and their actions in the body.
