Calcium Gluconate Tablets contain Calcium Gluconate. Tablets that are intended to be chewed before swallowing are prepared using Chocolate Basis or other suitable basis with a chocolate flavour.

The tablets comply with the requirements stated under Tablets and with the following requirements.

Content of calcium gluconate, C12H22CaO14,H2O

95.0  to 105.0% of the stated amount.


A.  Extract five tablets, finely powdered, with two 25-ml quantities of petroleum spirit (boiling range, 40° to 60°), discard the extracts and repeat the extraction with three 10  ml quantities of water, again discarding the extracts. Dissolve the residue as completely as possible in 30  ml of hot water, filter and to 0.5  ml of the filtrate add 0.05  ml of iron(iii) chloride solution R1. An intense yellow colour is produced.

B.  To a volume of the filtrate obtained in test A containing 0.5  g of Calcium Gluconate add 0.65  ml of glacial acetic acid and 1  ml of phenylhydrazine, heat on a water bath for 30  minutes, cool and induce crystallisation. Filter, dissolve the residue in 10  ml of hot water, add a few mg of activated charcoal, shake, filter, allow the filtrate to cool and induce crystallisation. A white, crystalline precipitate is produced. The melting point of the crystals, after drying, is about 201°, with decomposition, Appendix V A.

C.  The powdered tablets yield the reactions characteristic of calcium salts, Appendix VI.

Test solution  Use the filtered dissolution medium diluted, if necessary, with water to give a concentration suitable for the instrument used.

Standard solutions  Use calcium standard solution (100  ppm Ca) suitably diluted with water.

Determine the total content of calcium in the dissolution medium and calculate the content of calcium gluconate taking each mg of calcium to be equivalent to 11.21  mg of C12H22CaO14,H2O.


Weigh and powder 20  tablets. Ignite a quantity of the powder containing 0.5  g of Calcium Gluconate, cool and dissolve the residue with gentle heat in 5  ml of 2m hydrochloric acid. Filter, wash the residue on the filter with water and dilute the combined filtrate and washings to 50  ml with water. Neutralise with 5m ammonia, using methyl orange solution as indicator, add 5  ml of 8m sodium hydroxide and titrate with 0.05m disodium edetate VS using calconcarboxylic acid triturate as indicator. Each ml of 0.05m disodium edetate VS is equivalent to 22.42  mg of C12H22CaO14,H2O.
