Co-magaldrox Oral Suspension

Action and use



Co-magaldrox Oral Suspension is a suspension containing Magnesium Hydroxide and Dried Aluminium Hydroxide in a suitable flavoured vehicle. The amount of dried aluminium hydroxide is adjusted to give the required content of Al2O3.

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

Content of magnesium hydroxide, Mg(OH)25

90.0  to 110.0% of the stated amount.


A.  Mix 5  ml with 10  ml of 2m hydrochloric acid, add 5  drops of methyl red solution and heat to boiling. Add 6m ammonia until the solution becomes yellow, continue boiling for 2  minutes and filter. To 1  ml of the filtrate add 1  ml of 6m ammonia and 1  ml of 2m ammonium chloride; no precipitate is produced. Add 0.25m disodium hydrogen orthophosphate; a white, crystalline precipitate is produced which is insoluble in 6m ammonia.

B.  To 5  ml add 10  ml of 2m hydrochloric acid. The solution yields the reaction characteristic of aluminium salts, Appendix VI.

Heavy metals

Not more than 10  ppm when determined by the following method. Dissolve 8.0  g in 20  ml of 3m hydrochloric acid with the aid of heat, filter if necessary and add sufficient water to produce 50  ml (solution A). Transfer 25  ml of solution A to a 50  ml Nessler cylinder, adjust the pH to between 3.0 and 4.0 using 6m ammonia, add sufficient water to produce 40  ml and mix. Add 10  ml of freshly prepared hydrogen sulphide solution, mix and allow to stand for 5  minutes. When viewed down the vertical axis of the tube against a white background the colour of the solution is not more intense than that of a solution prepared at the same time and in the same manner using a solution of 2  ml of lead standard solution (20  ppm Pb) diluted to 25  ml with water in place of solution A adjusted to a pH between 3.0 and 4.0 using either 1m acetic acid or 6m ammonia and beginning at the words 'add sufficient water to produce 40  ml …' (standard solution). The colour of the standard solution is not as intense as that of a solution prepared at the same time and in the same manner but using a mixture of 25  ml of solution A and 2  ml of lead standard solution (20  ppm Pb) adjusted to a pH between 3.0 and 4.0 using either 1m acetic acid or 6m ammonia and beginning at the words 'add sufficient water to produce 40  ml …'.

Microbial contamination

Carry out a quantitative evaluation for enterobacteria and certain other Gram-negative bacteria, Appendix XVI B1. 0.01 ml of the preparation gives a negative result, Table I (most probable number of bacteria per gram fewer than 102).



For Al2O3

To a weighed quantity containing 1.5  g of dried aluminium hydroxide add 20  ml of water, stir and slowly add 10  ml of hydrochloric acid. Heat gently, if necessary, to aid solution, cool, filter, wash the filter well with water, dilute the combined filtrate and washings to 200  ml with water and mix. Reserve a portion of the solution for the Assay for magnesium hydroxide. To 10  ml add 20  ml of water and, with continuous stirring, 25  ml of 0.05m disodium edetate VS followed by 20  ml of a mixture of equal volumes of 2m ammonium acetate and 2m acetic acid. Heat near the boiling point for 5  minutes, cool, add 50  ml of absolute ethanol and 3  ml of a freshly prepared 0.025% w/v solution of dithizone in absolute ethanol. Titrate the excess of disodium edetate with 0.05m zinc sulphate VS until the colour of the solution changes from greenish blue to reddish violet. Each ml of 0.05m disodium edetate VS is equivalent to 2.549  mg of Al2O3. Determine the weight per ml of the suspension, Appendix V G, and calculate the percentage content of Al2O3, weight in volume.

For magnesium hydroxide

To a volume of the solution reserved in the Assay for Al2O3 containing about 40  mg of magnesium hydroxide add 200  ml of water and 20  ml of triethanolamine and stir. Add 10  ml of ammonia buffer pH 10.9 and cool the solution to between 3° and 4° by immersion in iced water. Titrate the cooled solution with 0.05m disodium edetate VS using mordant black 11  solution as indicator. Each ml of 0.05m disodium edetate VS is equivalent to 2.916  mg of Mg(OH)2. Using the weight per ml of the suspension, calculate the percentage content of Mg(OH)2, weight in volume.
