Abstract :

In accordance with the monographs of the European and US Pharmacopoeias (Ph. Eur.; USP), for reasons of patient safety, the heavy metals in pharmaceutical finished products and raw materials must not exceed the specified limit values and must be tested for that. Heavy metals can be introduced into the product by catalysts, synthesis reagents and even by the manufacturing process itself. In the manufacturing of pharmaceutical products, catalysts containing heavy metals are often involved in the synthesis. Heavy metals can also transfer into the process by abrasion or by leaching (e.g. Fe, Ti, Cu, Cr and so on.) If they are not removed efficiently, then the tainted products could get into the market. Legal regulations For many years, it has been known that certain heavy metals exhibit toxic effects even at low concentrations. As a result, limit values for the protection of the patients have been defined in the legislation and in the various pharmacopoeias (e.g. Ph. Eur., USP, JP, BP). Detection methods If testing is not performed for a specific heavy metal, the most common source of evidence nowadays come from a limit test being carried out. After treatment, the heavy metal is complexed with thioacetamide or precipitated as a sulphide. Then, one compares the resulting colouring of the sample solution against that from a reference lead solution. These limit tests still form the majority of testing for heavy metals in the current national and international Pharmacopoeias (e.g. Ph. Eur. 2.4.8 or USP <231>). Thereby, it is possible however to make only a semiquantitative statement about the total contents of heavy metals in the sample, and in addition – and additionally, only for those heavy metals that actually form dark coloured complexes or sulphides.
