Preliminary safety and efficacy profile of prucalopride in the treatment of systemic sclerosis (SSc)-related intestinal involvement: results from the open label cross-over PROGASS study

Background Prokinetics are used to treat enteric dismotility symptoms in systemic sclerosis (SSc) patients, but they often lack adequate efficacy. The most effective prokinetics belonging to the serotonin (5-HT4) receptor agonists class were withdrawn due to cardiac toxicity in relation to modest 5-HT4 receptor affinity. Prucalopride is a high-affinity 5-HT4 receptor agonist with no major cardiac issues, for which the efficacy in SSc has not yet been assessed. Methods Forty patients with self-reported mild to moderately severe enteric symptoms were enrolled in a cross-over 2 × 2 study. Subject... Mehr ...
