VALENTIM MARICOTO SILVA, MF  y  AGUILAR ABRANTES NOGUEIRA, GM. Opioid analgesics available in Portugal approved for chronic pain. Rev. OFIL·ILAPHAR [online]. 2020, vol.30, n.4, pp.363-364.  Epub 25-Mayo-2021. ISSN 1699-714X.  https://dx.doi.org/10.4321/s1699-714x2020000400020.

Chronic pain has a prevalence of 37% in the Portuguese population, causing physical limitations, psychological and social problems and a great decrease in the quality of life. In many types of chronic pain, opioid drugs are the only options that can provide pain relief, and therapy using this pharmacotherapeutic group should be started when other options have failed.

This paper aims to review the main characteristics of opioid analgesics, including side effects and available pharmaceutical forms, both for baseline and rescue therapy.

Palabras clave : Opioid; pain; analgesia; analgesic; Portugal.
