Pulmonary arterial hypertension is a syndrome resulting from restricted flow through the pulmonary arterial circulation resulting in increased pulmonary vascular resistance and ultimately leading to right heart failure.
It is a part of the spectrum of pulmonary hypertension, which is hemodynamic and pathophysiological condition defined as an increase in mean pulmonary arterial pressure ≥25 mmHg at rest.
Typical symptoms include progressive dyspnea on exertion, palpitations, fatigue, weakness, angina, syncope and abdominal distention.
Inhaled treprostinil significantly improves exercise capacity in terms of 6-minute walking distance (6MWD) over 16 weeks compared with placebo in patients with pulmonary hypertension associated with interstitial lung disease (ILD), according to the INCREASE trial presented at ATS 2020.
Adding selexipag to the double combination therapy of macitentan and tadalafil (triple combination) improved multiple outcomes in patients newly diagnosed with pulmonary arterial hypertension (PAH), results of the phase IIIb TRITON* trial showed.
Use of the oral phosphodiesterase-5 inhibitor udenafil in the treatment of patients with pulmonary arterial hypertension is safe and leads to a significant increase in exercise capacity, according to the results of a phase IIB trial.
The reduced mortality/morbidity benefit previously demonstrated with selexipag in patients with pulmonary arterial hypertension (PAH) may be more pronounced when treatment is initiated soon after diagnosis, according to results of a post hoc analysis of the GRIPHON* study presented as a poster at ATS 2019.
Patients with chronic thromboembolic pulmonary hypertension (CTEPH) may experience improvements in exercise capacity and other outcomes when treated with a continuous, subcutaneous, high dose of treprostinil, according to the phase III CTREPH* trial.
Pulmonary arterial hypertension (PAH) may be the first manifestation of primary Sjögren's syndrome (pSS) in patients with Raynaud’s phenomenon, high-titre rheumatoid factor, hepatic injury or pericardial effusion, according to a recent study.
Patients with combined pulmonary fibrosis and emphysema (CPFE) are likely to develop pulmonary hypertension, and this likelihood may be explained by the summed extents of interstitial lung disease (ILD) and emphysema, according to a study.

Treatment with the DPP 1* inhibitor brensocatib prolonged time to exacerbation and reduced exacerbation rates in patients with non-cystic fibrosis bronchiectasis, according to the phase II WILLOW** study presented at ERS 2020.
Almost three-quarters of adverse events (AEs) related to medication errors in over-the-counter (OTC) cough and cold medications (CCMs) for paediatrics required evaluation by healthcare facility and majority of the cases were due to dosing errors, a surveillance study has found, highlighting the need for interventions to mitigate medication errors.
A fixed-dose triple therapy of ICS, LAMA, and LABA* is superior to dual therapies of either LAMA-LABA or ICS-LABA for controlling exacerbations in patients with moderate-to-very-severe COPD**, according to the large ETHOS*** trial.
