Abstract
The present invention relates to a process for the preparation of injectable solutions of pharmaceutical products and/or of diagnostic agents, characterized by an extremely high degree of purity as regards the low content of bacterial endotoxins. The process of the invention provides for the prefiltering of the solutions by means of a microfiltering unit, a subsequent ultrafiltration and the recycling of the retentate from the ultrafiltration to the solution which emerges from the prefilter.
