B 800. 4.8 per cent, deficient in quinine sulphate and contained only
traces of ammonia. Vendor cautioned.
C 816. 34.6 per cent, deficient in quinine sulphate and 90.8 per cent,
deficient in ammonia. Vendor fined £2 with £2 2s. Od. costs.
Regarding the ammonia content these tablets are of little use as the
ammonium bicarbonate gives off its ammonia which penetrates the coating
and is lost. There is no excuse for the deficiency of quinine sulphate.
A satisfactory preparation is given in the Codex to the British Pharmacopoeia,
the quinine sulphate and ammonium bicarbonate being mixed with
paraffin and enclosed in a capsule.
Grey Powder.
C 130 (Informal). 14.2 per cent, deficient in mercury.
C 131 (Informal). 13.5 per cent, deficient in mercury.
C 166. 19 per cent, deficient in mercury. No action taken.
Quinine and Cinnamon Tablets.
B 730 (Informal). 32.4 per cent, deficient in quinine sulphate.
B 798. 32.8 per cent, deficient in quinine sulphate. Vendor cautioned.
The formula on the bottle showed 12.5 per cent, quinine sulphate, whereas
only 8.4 per cent, was found.
The manufacturers stated that their declaration was based on the uncoated
weight of the tablets, the uncoated tablet weighing 3 grains and sugar coated
5 grains.
This is misleading as the purchaser does not know how much quinine
sulphate is present in each tablet.
A tablet might be 90 per cent, coating, in which case the amount of
quinine sulphate in the remainder would be very small. To avoid misunderstanding,
the label should show the actual content of quinine sulphate per
tablet.
Sal Volatile.
C 605 (Informal). 95.4 per cent, deficient in alcohol.
C 633. 95.4 per cent, deficient in alcohol. Dismissed under the Probation
of Offenders Act. Vendor paid £2 2s. Od. costs. (Liq. Ammon.
Aromat. had been supplied instead of Sp. Ammon. Aromat. and the
same price charged.)
C 666 (Informal). 20 per cent, deficient in ammonia and 1.2 per cent,
deficient in carbon dioxide.
C 685 (Informal). 13.8 per cent, deficient in ammonia and 10.7 per cent,
deficient in carbon dioxide.
