Introduction:
The off-label use of drugs requires scientific support to balance risk/benefit, being limited to exceptional cases in which there are no therapeutic alternatives.
Methods:
Retrospective descriptive study of the reports of the Pharmacy and Therapeutics Committee between 2018 and 2022 in a third level hospital; analyzing the requests, drugs, final opinion, reasons, level of evidence and economic impact.
Results:
A total of 124 reports were analyzed, highlighting oncohematological (41.9%) and autoimmune (27.4%) diseases as main indications. Oncology (37.1%) and Pediatrics (18.5%) were the main applicants, with 87.9% for antineoplastic and immunomodulatory drugs. A total of 74.2% of the applications were approved due to lack of alternatives and solid evidence (phase II-III trials), while 25.8% were denied due to the availability of therapeutic options or insufficient evidence. In terms of cost, 53% of oncohematological drugs cost between €10,000-50,000/treatment and 62.1% of non-oncohematological drugs cost between €1,000-10,000/year. Approval of the rejected treatments would have generated an additional expenditure of €2,272,603.
Conclusion:
An increase of up to four times in the evaluation of off-label use drugs was evidenced, with a high approval rate.
