Abstract: The invention relates to a method of preparing an original sample (3) of biological origin with a view to detecting at least one component contained in it, whereby the original sample (3) is enclosed in a first container (1) and at least a part of this original sample (3) is transferred from the first container (1) into at least one reaction container, a reagent (9) or reagent mixture being placed beforehand in at least one of the reaction containers in order to prepare the original sample (3) and the component to be detected. In order to transfer at least a part of the original sample (3), two respective containers (1, 6) are connected to one another to form a closed, airtight system at least until at least the component(s) to be detected has (have) been rendered stable by reacting it (them) with the reagent (9) or reagent mixture at room temperature.

Abstract: The invention relates to an active ingredient patch in the form of a laminate, the patch comprising a carrier and a matrix of a single polymer and if appropriate another polymer and vitamin E.

Abstract: The present invention relates to cyclodextrin inclusion complexes of ranitidine hydrochloride which exhibit a novel, to date unknown crystalline structure, being significantly different from those of known "Form 1 and 2" and to the preparation of such inclusion complexes. The inclusion complexes are prepared from aqueous common solution or suspensions of ranitidine hydrochloride and cyclodextrin by removal of water. As complexing agents .alpha.-, .beta.- and gamma-cyclodextrins, their alkylated, hydroxy alkylated derivates or their suitable mixtures are utilized. Finally, the invention concerns pharmaceutical compositions comprising the new complexes.
