dc.description.abstract<p class="" style="white-space:pre-wrap;"><strong>Background</strong> Anthroposophic medicinal products (AMPs) are widely used in Europe and world-wide.</p><p class="" style="white-space:pre-wrap;"><strong>Objective</strong> To determine the frequency of reported adverse drug reactions (ADRs) from all AMPs on the market, in absolute numbers and relative to the maximum daily administration doses (MDADs). </p><p class="" style="white-space:pre-wrap;"><strong>Patients and Methods</strong> Retrolective safety analysis of AMP-related ADRs in pharmacovigilance databases of four AMP Marketing Authorisation Holders in Germany. For each ADR, information about the patient, outcome, causality and AMP was retrieved. Primary outcome was the frequency of reported ADRs relative to MDADs sold. </p><p class="" style="white-space:pre-wrap;"><strong>Results</strong> In the period 2010–2017, a total of 5506 ADRs were reported that had occurred in 2765 different patients, comprising 370 different AMPs. A total of 104 ADRs (1.9%) were classified as serious. The frequency of ADRs for all AMPs was 1.50 per million MDADs. For serious ADRs the frequency was 0.03 per million MDADs. ADRs were more frequently reported with parenteral AMP administration (injections) than with oral or local administration (18.85 vs. 0.59 vs. 1.61 ADRs per million MDADs, respectively; p &lt; 0.0001). The large majority of users (91.9%) had recovered or were recovering from the ADRs and there were no reports with a fatal outcome. Most frequently reported ADR symptom was injection site inflammation for parenteral AMPs (4.66 ADRs per million MDADs), nausea for oral AMPs (0.03 ADRs per million MDADs), and eye irritation for locally administered AMPs (0.23 ADRs per million MDADs). </p><p class="" style="white-space:pre-wrap;"><strong>Conclusions</strong> In this retrolective safety analysis of pharmacovigilance data, the frequency of ADRs to AMPs was 1.50 per million MDADs. Notably, the ADR frequency in this study based on spontaneous reporting is not directly comparable to frequencies in prospective clinical studies nor to frequencies based on other measures of patient exposure than MDADs.</p><p class="" data-rte-preserve-empty="true" style="white-space:pre-wrap;"></p><p class="" style="white-space:pre-wrap;"><strong>Citation: </strong>Jong, M.
