The Harmonized Microbial Limits Test (MLT) is microbial limit test for pharmaceutical products used in The United States, Europe and Japan as the principal Organic release test for non-sterile stable oral products meant for human use [one-4]. It is a compendia test meaning that it's posted and intended to be microbial limit test ep used “as is” with little or no variation from the method. The purpose of the harmonization of your test was in order to avoid unwanted testing duplication which happened previous to the Intercontinental harmonization work in 2009 [1,two].

Considering that the higher temperatures can degrade preservatives and potentiate other chemical things to do, testing AET at the upper temperatures would be evaluating the worst case situation. Accelerated testing is usually performed during improvement, and with adequate facts, AET testing of business yearly security batches is probably not essential. In the course of improvement, it is helpful to execute AET on the “base” components minus preservative, flavours, fragrance or progress-limiting variables at their cheapest stages. The pH must ideally be the predicted assortment closest to that favouring growth. Utilization of organisms past that required with the compendia is also proposed throughout this testing period.
