Review Comparative StudyA Focus on Macitentan in the Treatment of Pulmonary Arterial Hypertension.
The approval of macitentan has increased the number of pharmacological treatments of pulmonary arterial hypertension (PAH). Here, we review the effect on PAH of macitentan compared to other endothelin receptor antagonists. Drugs targeting the endothelin (ET) pathway include the selective ETA receptor antagonist ambrisentan, the ETA /ETB receptor antagonists, bosentan and macitentan, which were recently approved for PAH treatment. ⋯ In summary, macitentan has an efficiency comparable to bosentan and ambrisentan in the treatment of PAH. Patients treated with macitentan exhibited less adverse effects compared to bosentan and ambrisentan. In patients with PAH associated with ES, the trials with bosentan and macitentan do not seem comparable, and it needs to be clarified whether these drugs are effective when administered as part of a combination treatment in this condition.

Randomized Controlled Trial Comparative StudyThe ED95 of Nalbuphine in Outpatient-Induced Abortion Compared to Equivalent Sufentanil.
This prospective study evaluated the 95% effective dose (ED95 ) of nalbuphine in inhibiting body movement during outpatient-induced abortion and its clinical efficacy versus the equivalent of sufentanil. The study was divided into two parts. For the first part, voluntary first-trimester patients who needed induced abortions were recruited to measure the ED95 of nalbuphine in inhibiting body movement during induced abortion using the sequential method (the Dixon up-and-down method). ⋯ Both nalbuphine and the equivalent dose of sufentanil provided a good intraoperative and post-operative analgesic effect in outpatient-induced abortion. However, the post-operative morbidity of dizziness for nalbuphine was less than for sufentanil (p < 0.05), and the awakening time and the time to leave the hospital were significantly shorter than those of sufentanil (p < 0.05). Nalbuphine at 0.128 mg/kg was used in outpatient-induced abortion as an intraoperative and post-operative analgesic and showed a better effect compared with sufentanil.
