EMETICS These are the drug which gives rice emesis by which the contants of stomach gets. Expelled out through the oral cavity emetics are used in the treatment of poisoning. They act other by local irritation of gastric mucus or for example Ammonium bicarbonate, ipecacuaha or by directly on the CTZ. In the floor of 4 th ventricle of the medulla oblongata. Emetic results in evacuation of stomach. They are used in very little quantity in cough preparation also stimulate respiratory tract secretion. Emetic are given in poisoning in which the poison remains in stomach and do not cause emesis natural to avoids part of the poison into intestine for absorption by emetics are given before it's intelling for supplying the toxis substance into reduce of the hair dry and for saving for the intestine patient by Most of the salt produce emesis but in large dose. There are in better intestine which produce emetics in smaller dose. Fast drug which copper sulphate. It is also known as cupric sulphate having chemical formula CuSo4•5H2O. It constant not less than 98•5% and not more than 101•0% of CuSo4 • 5H2O.

PREPARATIONS

FIRST METHOD it is prepared by rousting copper containing sulphide in presence of air or by eating copper content break. So the mixture of copper sulphide and copper oxide for in this process then it should be taken with dilute h2so4 and filter. After that sufficient into the concentrate and allowed to crystlization to separate the crystal of copper.

SECOND METHOD it is also often by preeting granulated copper in presence of air which sulphuric acid 2Cu + 2H2So4 + O2 > 2CuSo4 + 2H2O This solution is than filter in the vovarate to crystlization for separation of copper sulphate.

PROPERTIES It is a deep blue triclic crystal or blue crystalline granules powder. It efflorescence slowly in dry air and the crystal get coured with a white anhydrous salt. It redouble in boiling water very slowly soluble in glycerol and almost in soluble in alcohol. It is stable up-to heat of 60 degree centigrade and 100 degree centigrade it loses two water molecules on 140 degree centigrade it loses another molecular of water at 200 degree centigrade. It form as anhydrous salt and run higher temperature it decomposes into So2 and oxygen and black cupric oxide. It is equous solution is acidic in nature. 2cuso4 > Cu + 2So2 + O2

TEST FOR PURITY It has to be tested for acidity and clarity of solution, Arsenic, Iron, Lead and Zinc.

STORAGE It has to be stored in a well closed container a wave from air heat and moisture.

USES It is used as an emetic and in the treatment of phosphorus poisoning. It is also used an astringent and consist externally for its used. Agent emetic can be dangerous Large and corrosive dose.
