Question
Posted on: March 6 2013We make following preparation: 10 g codeine syrup 5 g NaHCO3 0.05 g chlorophyllinum pulvis 100% (Na-Cu-chlorophylline complex) 5 g spiritus 0.5 g Aetheroli pini 100 ml Aqua Conservans, Sirupus simplex AD 200 ml
Answer
(in collaboration with Apoth I. Decraene)
There are apparently two problems: the secretion of volatile oil and precipitation of dye. To solve the first one I would double the amount of alcohol to 10 g and add a small amount of solubilizer (5 G Crempophor EL). To dissolve the bicarbonate and the chlorophyll, 50 ml of water is sufficient so that it is perhaps better to halve the amount of aqua conservanges and supplement it with sugar syrup up to 200 ml. The result is a free viscous syrup, which is tasty and does not have an OL Stains with a pH between 7 and 8, which prevents the weakening of the chlorophyll.
