ABSTRACT
Se llevó a cabo un estudio observacional para analizar si tapentadol de liberación prolongada (LP) puede considerarse un tratamiento de primera línea para pacientes con dolor crónico postraumático (DCPT). Métodos: Se presenta una serie de casos de la práctica clínica real de pacientes con DCPT producido por accidentes de trabajo. Antes de ingresar al estudio, todos los pacientes recibían tramadol, que se interrumpió cuando se inició la administración de tapentadol LP. Las evaluaciones de dolor incluyeron una escala de valoración numérica, el cuestionario DN4 y la escala de Impresión Global de Cambio del Paciente (PGIC, Patients' Global Impression of Change). Se recuperaron y registraron los eventos adversos. Resultados: 94 pacientes participaron en el estudio y 77 (82 %) completaron todas las visitas predefinidas. Cerca de la mitad de los pacientes informaron dolor crónico que tenía una duración de al menos 3 años; se observó un componente neuropático en el 87 % de los pacientes. El puntaje de dolor se redujo en 1,5 puntos luego del primer mes de tratamiento con tapentadol LP y en 2,48 puntos luego de 4 meses (p<0,05). También se asoció la administración de tapentadol LP con una reducción del 28,9 % de la dosis concomitante de pregabalina (p<0,01). De acuerdo con el cuestionario PGIC, el 74 % y el 77,9 % de los pacientes informó mejoría luego de uno y cuatro meses de tratamiento, respectivamente. El perfil de seguridad fue consistente con los datos actuales sobre tapentadol LP. Conclusión: El dolor osteomuscular crónico es una enfermedad prevalente que se caracteriza por tener resultados terapéuticos deficientes y se asocia a una mayor discapacidad y una mala calidad de vida. En este estudio de la práctica clínica real en pacientes que trabajan y que cuentan con un componente de dolor neuropático elevado, se observó que tapentadol LP produce efectos beneficiosos en términos del control del DCPT, y se obtuvieron índices altos de eficacia y seguridad.
An observational study was carried out to analyze whether prolonged-release (PR) tapentadol may be considered a first-line treatment for patients with chronic post-traumatic pain (PTD). Methods: A case series of cases of patients with PTFE caused by work accidents in a real clinical practice setting is described. Before entering the study, all patients were receiving tramadol, which was discontinued when PR tapentadol was started. Pain assessments included a numerical rating scale, the DN4 questionnaire, and the Patients' Global Impression of Change (PGIC) scale. Adverse events were retrieved and described. Results: 94 patients participated in the study and 77 (82%) completed all the predefined visits. About half of the patients reported chronic pain that lasted for at least 3 years. A neuropathic component was reported in 87% of patients. The pain score was reduced by 1.5 points after the first month of treatment with PR tapentadol and by 2.48 points after 4 months (p < 0.05). Administration of PR tapentadol was also associated with a concomitant reduction of pregabalin dose of 28.9% (p < 0.01). According to the PGIC questionnaire, 74% and 77.9% of patients reported improvement after one and four months of treatment, respectively. The safety profile was consistent with current data on PR tapentadol. Conclusion: Chronic musculoskeletal pain is a prevalent disease characterized by poor therapeutic results and associated with increased disability and poor quality of life. In our study in a real clinical practice setting with patients with a high neuropathic pain component, PR tapentadol produced beneficial effects in terms of DCPT control, and high efficacy and safety rates were obtained. Keywords: tapentadol, chronic pain, pain caused by work accidents, chronic post-traumatic pain, evidence from real clinical practice.

Pain can be caused by several mechanisms, and the development of chronic pain (also known as pain chronification) is a complex and often unpredictable process. Opioids, tramadol, and tapentadol provide pharmacological solutions to chronic pain of cancer or non-cancer origins, particularly if central sensitization is present. It may also be indicated for short-term use in acute pain.Despite large studies and meta-analyses of opioids for a variety of pain conditions, the evidence for its clinical effectiveness is still unclear. This is, however, mostly due to significant heterogeneity and bias between studies assessed. The dual analgesic mechanisms of tramadol and tapentadol appear to be effective options for pain relief, with an overall lower incidence of opioidrelated adverse effects. Tapentadol has an analgesic effect comparable to the strong opioids,which appearto be mediated by itsgreater mu opioid receptor activity and more selective noradrenaline reuptake inhibition. Tramadol produces less analgesia than tapentadol, but it is also associated with reduced opioid-related adverse effects and dependence. The opioids and tramadol may be significantly affected by polymorphisms of CYP2D6, while this effect is lessened with tapentadol
