communications network, gas-powered automobiles and high-speed elevated trains. The science has opened up an entirely new world for us. And our lives have become easier and more comfortable. With the help of science we have estimated about 8,000 chemotherapeutic exogenous non-nutritive chemical substances which when taken in the
solid form by the mouth enter the digestive tract and there they are transformed into a solution and passed on to the liver where they are chemically altered and finally released into the blood stream. And through blood they reach the site of action and binds reversibly to the target cell surface receptors to produce their pharmacological effect. And after their pharmacological effect they slowly detaches from the receptor. And then they are sent to the liver. And there they are transformed into a more water soluble compound called metabolite and released from the body through urine, sweat, saliva, and excretory products. However, the long term use of chemotherapeutic drugs...
