Absorb moisture and slowly gets oxidized to sodium nitrate. Colourless to slightly yellow crystals, odourless, saline taste.The solution is concentrated to crystallize out the product.

They act by preventing the absorption of poison into the body or expel out the poisoning by emesis or eliminate through urine.Īctivated charcoal absorb the poison prior to absorption into the systemic circulation form intestinal wall.Ĭopper sulphate, magnesium sulphate and sodium monohydrogen phosphate in activate the poison prior to absorption and precipitate the toxic material as in insoluble saltĪntidote for selected inorganic poison and drug overdose Poison/Drug OverdoseĪntacid or Weak Alkali (Milk of magnesia), Avoid Induce vomitingĬhemical Antagonism, Acid base neutralizationĪntidote for selected inorganic poison and drug overdose Sodium NitriteĪbsorbing of nitrogen oxide gas (NO) by sodium carbonate solution. Sodium thiosulfate (it convert the systemic toxic cyanide into non toxic thiocyanate), EDTA (chemical agent for heavy metal poisoning). These antidotes react by combining with the poison and change its chemical nature by converting the poison into inactive or harmless compounds. Sodium nitrite (used in cyanide poisoning), atropine and Physiostigmine are two antidotes for each other. They are used after some of poison is observed in the circulation. The produce the effect opposite to that of the poison. Physiological antidote also called antagonist.

Displacing the poison from a receptor or competing for the receptorĬlassification of Antidote Classification of AntidotesĪccording to mechanism of action antidote are classified below Physiological antidotes.

Inhibiting metabolism to a toxic metabolite.

Antidotes are drugs designed to counteract toxins/poison/xenobiotics.Īn antidote can act in a number of ways like
