Capsaicin 8% patch for treprostinil subcutaneous infusion site pain in pulmonary hypertension patients.
    British journal of anaesthesia, 2014, Volume: 112, Issue:2

    Treprostinil sodium improves haemodynamics and symptoms in pulmonary arterial hypertension (PAH) patients, but its subcutaneous (s.c.) administration can produce severe local site pain, and lead to discontinuation of vital treatment. Treprostinil is a prostacyclin analogue which stimulates prostacyclin receptors in skin nociceptor terminals, resulting in pain and cutaneous hypersensitivity, for which current pain remedies have limited effect. Capsaicin 8% patch relieves neuropathic pain for 3 months after a single 60 min cutaneous application; we investigated whether its pre-application can reduce s.c. trepostinil-induced pain.. A single-centre, double-blind, randomized, placebo-controlled, crossover study was conducted to assess the safety and efficacy of a single capsaicin 8% patch pre-application for s.c. treprostinil pain in 11 PAH patients, relative to control patch with low-dose capsaicin 0.075% cream.. The primary efficacy endpoint, mean difference between the two treatment arms in an 11-point numerical pain rating scale from baseline to 2 weeks after patch applications, was significantly lower on the capsaicin 8% patch treatment arm [P=0.01, mean difference=-1.47 units, 95% credible interval (CI): -2. 59 to -0.38] in the patients who completed the study per protocol, although intention-to-treat analysis did not show significant difference (P=0.28). Heat pain thresholds were decreased (P=0.027, mean difference=5.43°C, 95% CI: 0.71-10.21) and laser Doppler flux increased (P=0.016, mean difference=370 units, 95% CI: 612 to 127.9) at the application site immediately after capsaicin 8% patch, confirming activity.. Further investigation of the efficacy of capsaicin 8% patch in this indication is warranted.

Treprostinil for severe inoperable chronic thromboembolic pulmonary hypertension.
    Journal of thrombosis and haemostasis : JTH, 2007, Volume: 5, Issue:3

    Chronic thromboembolic pulmonary hypertension (CTEPH) results from non-resolving pulmonary thromboemboli that are resistant to plasmatic anticoagulation. Because of a secondary pulmonary arteriopathy accompanying major vessel obstruction, the disorder may be a target for vasodilator therapy.. In an open-label uncontrolled study, we investigated the prostacyclin analog treprostinil given s.c. in patients with severe inoperable CTEPH.. Between September 1999 and September 2005, 25 patients were included if their World Health Organization (WHO) functional class was III or IV, if their six-minute walking distance (6-MWD)

Subcutaneous treprostinil in pulmonary arterial hypertension: Practical considerations.
    The Journal of heart and lung transplantation : the official publication of the International Society for Heart Transplantation, 2010, Volume: 29, Issue:11

    Treprostinil, which is available for subcutaneous (SC) and intravenous (IV) administration, has demonstrated efficacy in increasing exercise capacity, reducing signs and symptoms of pulmonary arterial hypertension (PAH), and improving cardiopulmonary hemodynamics in patients with PAH; however, the infusion site pain commonly experienced with SC treprostinil has limited its use. Prospective and observational clinical studies have shown that the dose of SC treprostinil can be escalated at a higher rate than described in early clinical trials to achieve symptom relief, in part because of favorable tolerability of treatment and the apparent dose independence of site pain. In addition, pain management protocols that include non-pharmacologic and pharmacologic (i.e., topical and systemic) approaches provide analgesic relief from infusion site pain. With experience, physicians and patients have recognized that some infusion sites are better than others, and the frequency of site rotation can be reduced to improve tolerability. Dosing to achieve rapid onset of efficacy and proactively managing infusion site pain enhance the likelihood for a patient with PAH to maintain and derive benefit from SC treprostinil therapy.
