Familial hypercholesterolemia (FH) is a disease associated with very high plasma concentrations of low-density lipoprotein cholesterol (LDL-C) and premature cardiovascular disease. It is difficult in these high risk patients, exposed lifelong to very high LDL-C, to reach target LDL-C concentrations, which require >50% LDL-C reduction, even when on maximally tolerated statin therapy and on apheresis if available. ⋯ In 2013 two new drugs were approved for the treatment of homozygous FH, namely the apolipoprotein B synthesis inhibitor mipomersen and the microsomal transfer protein inhibitor lomitapide. Objective of this narrative review is to discuss the available evidence on the safety and efficacy profile of these new drugs.

ReviewReversal of the novel oral anticoagulants dabigatran, rivoraxaban, and apixaban.
We summarize the available data related to reversing the anticoagulant effect of the oral direct thrombin and factor Xa inhibitors and provide our opinion on treating patients presenting with severe and life-threatening hemorrhage related to these agents. ⋯ In the absence of evidence in bleeding patients, animal models and ex-vivo studies suggest administration of coagulant factors in the form of hemostatic agents may be of benefit in reversing the effect of direct thrombin and factor Xa inhibitors. Specific reversal agents and clinical data in patients with hemorrhage remain an unmet need.

The single-tablet regimen of the hepatitis C virus (HCV) NS5A inhibitor ledipasvir and the HCV NS5B polymerase inhibitor sofosbuvir (ledipasvir/sofosbuvir; Harvoni(®)) was recently approved in the US and the EU. The phase III ION trials included treatment-naive (ION-1 and -3) or treatment-experienced (ION-2) patients with chronic HCV genotype 1 infection (≈20 % of patients in ION-1 and -2 had cirrhosis, whereas no patient in ION-3 had cirrhosis). A sustained virological response 12 weeks' post-treatment (SVR12) was seen in 99 % of treatment-naive patients receiving ledipasvir/sofosbuvir for 12 weeks in ION-1, with no additional benefit conferred by the addition of ribavirin or extending the treatment duration to 24 weeks. ⋯ Data also support the use of ledipasvir/sofosbuvir in chronic HCV genotype 4 infection, in HCV and HIV co-infection and, in combination with ribavirin, in patients with chronic HCV genotype 1 or 4 infection who have decompensated cirrhosis or are liver transplant recipients and in chronic HCV genotype 3 infection. Oral ledipasvir/sofosbuvir was generally well tolerated. In conclusion, ledipasvir/sofosbuvir is an important new single-tablet regimen that represents a significant advance in the treatment of chronic hepatitis C.

Review Comparative StudyWarfarin versus dabigatran etexilate: an assessment of efficacy and safety in patients with atrial fibrillation.
Oral anticoagulation is the mainstay for stroke and thromboembolic event prevention in patients with atrial fibrillation (AF). Given limitations of warfarin therapy, non-vitamin K oral anticoagulants have been developed including direct thrombin inhibitors (i.e., dabigatran etexilate). Dabigatran etexilate has been tested thoroughly in terms of efficacy and safety in clinical trials and studies, involving 'real-world' cohorts. In this review, currently available evidence in patients with non-valvular AF is discussed. ⋯ Dabigatran etexilate appeared to have several pharmacokinetic and pharmacodynamic advantages over warfarin, as well as a favorable efficacy and safety profile being at least noninferior and often superior to warfarin in patients with non-valvular AF. The latter was shown in the clinical trials, meta-analyses and studies with 'real-world' data. Currently ongoing trials will expand the body of evidence on warfarin and will aid decision making in currently controversial areas. Important limitations of dabigatran etexilate include contraindications for its use in patients with prosthetic heart valves and end-stage chronic kidney disease.

Review Meta Analysis Comparative Study
Efficacy and safety of ramosetron versus ondansetron for postoperative nausea and vomiting after general anesthesia: a meta-analysis of randomized clinical trials.
Postoperative nausea and vomiting is a common side effect of general anesthesia. In this study, we performed a meta-analysis on the efficacy and safety of ramosetron versus ondansetron in the prevention of postoperative nausea and vomiting using the most recently published randomized controlled clinical studies. ⋯ Our meta-analysis demonstrates that ramosetron was more effective than ondansetron in the prevention of early POV (0-24 hours) with fewer recorded side effects. However, our study did not reveal any statistically significant differences in efficacy between ramosetron and ondansetron in the prevention of PON or late POV (at 24-48 hours).
