TRINIDAD, J. M. y TORRES, L. M.. Using the 8% capsaicin patch for treatment of pain by subcutaneous infusion of treprostinil. Rev. Soc. Esp. Dolor [online]. 2012, vol.19, n.3, pp.134-137. ISSN 1134-8046.
Background: PH (Pulmonary Hypertension) is a low-prevalence disease (15 cases per 1 million inhabitants), but is nevertheless a serious process with high mortality. Treprostinil is a new drug for the PH treatment, it is a prostacyclin with a half-life of 2-3 hours, which permits subcutaneous administration with rapid absorption and 100% bioavailability. The issue with treprostini is the high rate of drop-outs due to pain at the injection site. Aims: to reduce the rate of drop-outs due to pain at the injection site with the use of Treprostinil Methods: we searches in PubMed and Tripdatabase, fore terms, "capsaicin", "qutenza", "treprostinil", and "pulmonary hypertension", finding no related publication. The treatment with capsaicin 8% patch, was performed for one hour, according to the protocol, the peri-umbilical abdominal area (injection site) was delimited and the patch administered for one hour. Results: erythema at the administration site was subsequently observed, albeit with no further incidents. Good treatment tolerance and discharge. In the control after 1 month, the patient reported changing the injection site to the treated area with a very striking reduction in pain (VAS 2-3) that enabled him to lead a normal life. The patient's satisfaction is very high, and he requires no coadjuvant or rescue treatment. At the 3-month control, the patient continues with the same level of analgesia Conclusions: capsaicin 8% patch could be a valid alternative to be considered in the analgesic control of patients on treatment with subcutaneous treprostinil.
