In the investigation, developed during 2014-2015 biennium, the mentioned effect was verified starting from the adverse reactions referred by the patients and the predominant symptoms that justified the drug prescription. The cascade effect prevailed in the elderly with more than 3 diagnosed disorders, although it was also presented in those that suffered from just 1 or 2. In all the identified cases there was more than one prescriptor for the follow up of the affected patients
