Claris lifesciences is an international most admired pharmaceutical company, in the business of manufacturing and marketing of high end injectables with focus on new drug delivery systems for treatment of critical illnesses and diseases. Claris lifesciences manufactures grelyte. Electrolyte g is gastric replacement solution. It provides electrolytes lost via gastric suction or vomiting. Gastric juice is always acidic due to its acidic contents. Therefore, loss of gastric juice due to any reason also causes loss of acidity. In turn, alkalosis develops due to h+ ion deficit. The solution contains ammonium ions which are converted to urea and hydrogen ions by the liver. Thus hydrogen ion deficit produced by gastric juice loss is replaced.
