The factor Xa inhibitor edoxaban (Lixiana(®)) is a new direct oral anticoagulant recently approved in the EU for the prevention of stroke and systemic embolic events (SEE) in patients with nonvalvular atrial fibrillation and one or more risk factors. In the large, randomized, double-blind, double-dummy, ENGAGE AF-TIMI 48 trial, oral edoxaban dosages of 30 and 60 mg once daily for a median treatment duration of 907 days in patients with moderate-to-high-risk nonvalvular atrial fibrillation were noninferior to warfarin for the incidence of first stroke or SEE. ⋯ Edoxaban has a rapid onset of action, a short half-life, few drug interactions and offers the convenience of oral, once-daily, fixed-dose administration, without the need for coagulation monitoring and without regard to food. Therefore, edoxaban is an effective and well tolerated therapeutic option in patients with nonvalvular atrial fibrillation.

ReviewBleeding Risk, Management and Outcome in Patients Receiving Non-VKA Oral Anticoagulants (NOACs).
Modern direct-acting anticoagulants are rapidly replacing vitamin K antagonists (VKA) in the management of millions of patients worldwide who require anticoagulation. These drugs include agents that inhibit activated factor X (FXa) (such as apixaban and rivaroxaban) or thrombin (such as dabigatran), and are collectively known today as non-VKA oral anticoagulants (NOACs). Since bleeding is the most common and most dangerous side effect of long-term anticoagulation, and because NOACs have very different mechanisms of action and pharmacokinetics compared with VKA, physicians are naturally concerned about the lack of experience regarding frequency, management and outcome of NOAC-associated bleeding in daily care. This review appraises trial and registry (or "real-world") data pertaining to bleeding complications in patients taking NOACs and VKA and provides practical recommendations for the management of acute bleeding situations.

Randomized Controlled Trial Comparative StudyPharmacokinetics and Tolerability of the Novel Oral Prostacyclin IP Receptor Agonist Selexipag.
Targeting the prostacyclin pathway is an effective treatment option for pulmonary arterial hypertension (PAH). Patients with PAH have a deficiency of prostacyclin and prostacyclin synthase. Selexipag is an orally available and selective prostacyclin receptor (IP receptor) agonist. Selexipag is hydrolyzed to its active metabolite ACT-333679, also a selective and potent agonist at the IP receptor. ⋯ Selexipag exhibits a good tolerability profile and PK properties that warrant further investigation.

Cardiovascular disease continues to be the most common cause of mortality in women in the USA. As a result, greater emphasis has been placed on preventive measures. Studies examining the role of aspirin and HMG-CoA reductase inhibitors (statins) have shown important clinical differences in men versus women in the preventive realm. ⋯ This review presents a summary of the past and current guidelines. In addition, important clinical trials influencing current era practice are also discussed. Both strengths and limitations of these studies are described in detail, along with recommendations regarding future directions and the scope of aspirin and statin use for primary and secondary prevention of cardiovascular disease.
