Estabilidad de los supositorios de quitina

chitin suppositories are a new option in anorectal threapeutics, whose stability should be evaluated. the behaviour of 3 lots of suppositories made at a pilot scale and stored at 3 different temperatures by a period of 2 years was analyzed. periodical checkings of the organoleptic properties, of the weight and liquefaction time parameters, as well as of the content of chitin were carried out by combining a gravimetric technique and infrared spectroscopy . the stability was investigated from the microbiological point of view by a differential count. the results were statisfactory for each evaluated parameter, since they were still within the limits for each of the assayed storage temperatures 2 years later.
