PURPOSE: A proportion of patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) do not achieve treatment goals or experience side effects on their current therapy. In such cases, switching patients to a new drug while discontinuing the first may be a viable and appropriate treatment option. CAPTURE was designed to investigate how physicians manage the switching of patients to riociguat in real-world clinical practice. Observations from the study were used to assess whether recommendations in the riociguat prescribing information are reflected in clinical practice...

Aims: It has been suggested that the nitric oxide-sensitive guanylyl cyclase (NO-GC)/cGMP-dependent signaling pathway affords protection against cardiac damage during acute myocardial infarction (AMI). It is, however, not clear whether the NO-GC/cGMP system confers its favorable effects through a mechanism located in cardiomyocytes (CMs). The aim of this study was to evaluate the infarct-limiting effects of the endogenous NO-GC in CMs in vivo. Methods and Results: Ischemia/reperfusion (I/R) injury was evaluated in mice with a cardiomyocyte-specific deletion of NO-GC (CM NO-GC KO) and in control siblings (CM NO-GC CTR) subjected to an in vivo model of AMI...

BACKGROUND: Despite multiple treatment options, the prognosis of pulmonary arterial hypertension (PAH) remains poor. PAH patients experience a high economic burden due to comorbidities, hospitalizations, and medication costs. Although combination therapy has been shown to reduce hospitalizations, the relationship between treatment, health care utilization, and costs remains unclear. OBJECTIVE: To provide a characterization of health care utilization and costs in real-world settings by comparing periods before and after initiating PAH-specific treatment...

Tadalafil, a selective phosphodiesterase type 5 inhibitor, is a long-acting oral agent for the treatment of erectile dysfunction of multiple etiologies. Although generalized tonic-clonic seizures were reported in a healthy man after taking tadalafil, the influence of tadalafil on seizure susceptibility has not been studied so far. Therefore, the aim of the present study was to investigate the effect of tadalafil on seizure threshold as well as on the activity of some first- and second-generation antiepileptic drugs in three acute seizure tests in mice...

BACKGROUND: Portopulmonary hypertension (PPH) is a relatively rare but well-recognized complication of end-stage liver disease. Moderate or severe PPH (mean pulmonary artery pressure [mPAP] ≥ 35 mmHg) is usually a contraindication for liver transplantation due to high operation-related mortality. Here, we report on a patient with moderate PPH whose condition was successfully managed with a phosphodiesterase type 5 (PDE5) inhibitor (tadalafil) and prostaglandin E1, who experienced rapid improvement of PPH after living-donor liver transplantation (LDLT)...

Non-selective beta-blockers are the mainstay of medical therapy for portal hypertension in liver cirrhosis. Inhibitors of phosphodiesterase-5 (PDE-5-inhibitors) reduce portal pressure in the acute setting by > 10% which may suggest a long-term beneficial effect. Currently, there is no available data on long-term treatment of portal hypertension with PDE-5-inhibitors. This case of a patient with liver cirrhosis secondary to autoimmune liver disease with episodes of bleeding from esophageal varices is the first documented case in which a treatment with a PDE-5-inhibitor for eight years was monitored...

This article summarizes years of challenging research on erectile dysfunction (ED), a condition that has an important social and cultural relevance. Preclinical and clinical research progress has led to new therapeutic approaches to ED in patients with different comorbidities and particularly in those with low urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH). These goals were possible only by combined work of specialists and researchers of different and intertwined medical disciplines. Currently, tadalafil (5 mg/d) is the best choice; other phosphodiesterase-5 inhibitors (PDE5i) are not included among options, despite the growing evidence of therapeutic effects...

Selective phosphodiesterase (PDE) 4 inhibitors have recently been introduced into the therapy of chronic obstructive pulmonary disease. However, suppression of airway reactivity and eosinophilic inflammation by increased intracellular cAMP could be beneficial in bronchial asthma as well. PDE5 inhibitors are used for the therapy of erectile dysfunction, pulmonary hypertension, and other cardiovascular diseases, but an expression of PDE5 in several immune cells suggests its perspectives in inflammation, as well...
