Ferrous Fumarate Oral Suspension 


Ferrous Fumarate Oral Suspension is a suspension of ferrous fumarate in a suitable flavoured vehicle.

The oral suspension complies with the requirements stated under Oral Liquids and with the following requirements.

Content of ferrous iron, Fe(ii)

90.0  to 110.0% of the stated amount.


A.  Mix a volume of the oral suspension containing about 0.6  g of ferrous fumarate with 20  ml of water, centrifuge and discard the supernatant liquid. Repeat with a further 20  ml of water. Add 15  ml of 3m hydrochloric acid to the residue, dissolve with minimum warming, cool and extract with two 50  ml quantities of ether. Wash the combined ether extracts with two 20  ml quantities of water, shake with anhydrous sodium sulphate, filter and evaporate to dryness. The infrared absorption spectrum of the residue, Appendix II A, is concordant with the reference spectrum of fumaric acid (RS 163).

B.  Mix a volume of the oral suspension containing about 0.3  g of ferrous fumarate in 10  ml of water, centrifuge and discard the supernatant liquid. To 0.2  g of the residue add 10  ml of a mixture of equal volumes of hydrochloric acid and water, dissolve with minimum warming, cool and filter. The filtrate yields reaction A characteristic of iron salts, Appendix VI.

Disperse a quantity of the oral suspension containing 0.28  g of ferrous fumarate in 20  ml of water, centrifuge and decant the supernatant liquid into a 500  ml graduated flask. Dissolve the residue in 20  ml of 1m sulphuric acid with minimum warming, cool and transfer the resulting solution to the same graduated flask, dilute to 500  ml with water and filter. To 5  ml of the filtrate in a Nessler cylinder add 40  ml of water and 5  ml of a 10% w/v solution of ammonium thiocyanate and mix. Any red colour produced is not more intense than that obtained by treating in the same manner a mixture of 42  ml of water, 0.2  ml of 1m sulphuric acid and 3  ml of a 0.0173% w/v solution of ammonium iron(iii) sulphate in 0.01m hydrochloric acid [6.0%, with respect to the content of Fe(ii)].

AssayMix a quantity of the oral suspension containing 0.28  g of ferrous fumarate with 10  ml of water and 25  ml of nitric acid, carefully warm until the vigorous reaction subsides, add a further 25  ml of nitric acid, evaporate to about 10  ml and allow to cool. Carefully add 10  ml of sulphuric acid to the cooled solution, evaporate until white fumes are evolved, cool, add 10  ml of nitric acid and again evaporate until white fumes are evolved. Repeat the evaporation with 10  ml quantities of nitric acid until all of the organic matter has been destroyed. To the resulting solution add 10  ml of water and 0.5  g of ammonium oxalate, evaporate until white fumes are evolved, add 50  ml of water, boil until a clear solution is obtained, cool, dilute to 100  ml with water and add dilute potassium permanganate solution, drop wise, until a faint pink colour persists for 10  seconds. Add 10  ml of hydrochloric acid and 3  g of potassium iodide, allow to stand for 15  minutes protected from light, add 10  ml of chloroform and titrate the liberated iodine with 0.1m sodium thiosulphate VS, with vigorous shaking, until the chloroform layer becomes colourless. Repeat the procedure without the preparation being examined. The difference between the titrations represents the amount of sodium thiosulphate required. Each ml of 0.1m sodium thiosulphate VS is equivalent to 5.585  mg of Fe(ii).
StorageFerrous Fumarate Oral Suspension should be protected from light.

The quantity of the active ingredient is stated both as the amount of ferrous fumarate and in terms of the equivalent amount of ferrous iron.

The packaging can be customized. the shipping term can be by sea, by air, and sample or small quantity can be shipped by DHL, FEDEX, EMS and TNT.
