A part of the drug is metabolized or split up, the rest is taken up into the blood and flows into the blood stream to go all over our body and becomes effective in various parts and more especially the sick part of our body. After that, the drug still goes to various parts of our body and returns to the liver to get further metabolized or split apart and that goes to our kidneys and gets neutralized and most of it gets eliminated or leaves our body as urine through our urinary tract. |
