Development of a highly sensitive high-performance thin-layer chromatography method for the screening and simultaneous determination of sofosbuvir, daclatasvir, and ledipasvir in their pure forms and their different pharmaceutical formulations.
The combination of sofosbuvir and daclatasvir or sofosbuvir and ledipasvir are now widely used as an ideal treatment of hepatitis C virus infection. For that purpose, a simple, sensitive, accurate, economic, and precise high-performance thin-layer chromatography was developed and validated for the determination of sofosbuvir, daclatasvir, and ledipasvir in their pure form as well as their different pharmaceutical products. The method used Merck HPTLC aluminum plates precoated with silica gel 60 F254 as a st...
Daclatasvir (DCV) combinated with Sofosbuvir (SOF) has shown good efficacy and safety profile for HCV patients. The aim was to evaluate the cost-effectiveness of DCV/SOF regimen versus HCV alternative treatments for patients who failed to achieve the SVR12 after a first DAA treatment from Italian perspective (PITER cohort).
To assess the efficacy and the risk of sofosbuvir-daclatasvir treatment among kidney transplant recipients (KTRs) with chronic hepatitis C virus (HCV) infection.
Clinical studies evaluating the efficacy of daclatasvir (DCV) for treatment of chronic hepatitis C virus (HCV) genotype 4 (GT4) infection are scarce. This study aims to evaluate the efficacy and safety of DCV plus sofosbuvir (SOF) with or without ribavirin (RBV) for treatment of Egyptian patients infected with HCV GT4.
Limited data exist on the pharmacokinetic profile of novel direct acting antivirals in kidney transplant recipients. Daclatasvir is primarily eliminated via the biliary route and sofosbuvir via the renal route; here we report the pharmacokinetic profile of combined treatment with these compounds in a prospective study of hepatitis C virus positive kidney transplant recipients (EudraCT: 2014-004551-32).
This study aimed to investigate the efficacy and safety of sofosbuvir plus daclatasvir (SOF+DCV) or simeprevir (SOF+SMV) in a randomized, open-label, non-inferiority trial of patients infected with hepatitis c virus (HCV) genotype 1, who were previously unresponsive to pegylated interferon and ribavirin or were treatment-naïve.
Due to the severity of chronic hepatitis C, there are multiple factors that can negatively affect the quality of life of infected patients. The aim of this study was to evaluate changes in the health-related quality of life (HRQoL) in patients under second-generation direct-acting antiviral (DAA) (interferon-free) therapies and to assess treatment effectiveness. This was an observational study conducted in Curitiba (Brazil) using two instruments (a generic and a specific) for measuring the quality of life i...
Since 2014, all-oral, interferon (IFN)-free, direct-acting antiviral (DAA) regimens including daclatasvir + asunaprevir dual regimen, ledipasvir/sofosbuvir combination, ombitasvir/paritaprevir/ritonavir combination, elbasvir + grazoprevir dual regimen, and glecaprevir/pibrentasvir combination have been approved for the treatment of hepatitis C. Studies on DAA regimens reported that DAA therapy causes far fewer adverse reactions compared with IFN therapy and exhibits high efficacy in treating hepatitis C vir...
Approximately 10%-15% of patients with hepatitis C genotype 1 (HCV GT1) experience virological relapse after all-oral antiviral regimen using simeprevir (SMV) and sofosbuvir (SOF). The efficacy and safety of treating such relapsers using ledipasvir/sofosbuvir (LDV/SOF) with/without ribavirin (RBV) has been limited.
Sofosbuvir (SOF) and daclatasvir (DCS) are novel, recently developed direct acting antiviral agents characterized by potent anti-hepatitis C virus action. A fast and efficient HPLC-UV method was developed, validated and applied for simultaneous determination of SOF and DCS in pharmaceutical formulations and biological fluids based on coupling liquid-liquid extraction with ultrasound and dual wavelength detection at λ; 260 and 313 nm for SOF and DCS, respectively. This approach provided simple, sensitive,...
Treatment of HCV infection with low-cost generic direct-acting antivirals (DAAs) available in India and other developing countries needs determination of HCV genotype ('genotype-dependent' regimens). Generic velpatasvir, a DAA that obviates the need for genotype determination ('pan-genotypic' regimen) recently became available but is costlier.
Sofosbuvir (SOF) and daclatasvir combination with or without ribavirin proved to be effective and safe in the treatment of hepatitis C virus infection. The study aimed to assess the efficacy of (SOF plus daclatasvir) combination + ribavirin in the treatment of treatment-experienced HCV genotype 4 Egyptian patients and to investigate the impact of IL-1β _31, IL-1β _511, and IL-1RN and T29C of ESR1 genes polymorphisms on treatment outcome. The study also aimed to assess the effect of the treatment on liver ...
Most direct-acting antivirals (DAA) and psychotropic drugs are metabolized by or induct/inhibit CYP enzymes and drug transporters. Although they are frequently co-administered, the drug-drug interactions (DDI) have been little studied. Therefore, the aim of this review is to describe the interactions between the approved DAA or combination regimens and the main psychoactive substances, including legal and illegal drugs of abuse. Areas covered: We performed a literature search on PubMed database on drug inte...
Direct-acting antivirals have become available for treating chronic HCV (hepatitis C virus) infection in adults and, recently, in children at least 12 years old. Our aim was to investigate the safety and efficacy of combined sofosbuvir (SOF)/daclatasvir (DCV) for HCV Genotype 4 in children aged 8 to 18 years or weighing 17 kg or more. 40 chronic HCV infected, treatment-naïve children with well compensated livers were recruited from two sites. Patients received combined therapy of SOF (400 mg/day for patien...
Sofosbuvir (SOF) and daclatasvir (DCS) are newly discovered anti-hepatitis C drugs that have direct antiviral activity. A novel and simple high-performance thin-layer chromatography (HPTLC) method was designed for simultaneous determination of SOF and DCS in miscellaneous matrices. The method adopts coupling HPTLC with dual wavelength spectrodensitometry. Consequently, this enabled sensitive, specific and cost-effective determination of the SOF-DCS mixture. The developed HPTLC procedure is based on a simple...
Generic antiepileptic drugs (AED) are significantly cheaper than brand name drugs, and may reduce overall health care expenditures. Regulatory bodies in Europe and North America require bioequivalence between generic and innovator drugs with regard to area under the plasma concentration-time curve (AUC) and peak plasma concentration (C ); strict cutoff values have been defined. The main issue is if bioequivalence ensures therapeutic equivalence. Are switches from brand to generic, or between generic AEDs en...
Hepatitis C virus (HCV) infection is considered as a major public health problem that, worldwide, chronically affects 170 million people. Due to progressive aging of the infected population, management of the elderly HCV-infected patients significantly emerged in the era of new therapies . This article is protected by copyright.

Daclatasvir is a nonstructural protein 5A replication complex inhibitor, and asunaprevir is a nonstructural protein 3 protease inhibitor for hepatitis C virus (HCV). In 2014, the combination therapy of daclatasvir and asunaprevir received the first global approval in Japan as the first nonribavirin, all-oral therapy for HCV treatment. The population pharmacokinetics (popPK) of daclatasvir and asunaprevir were characterized by nonlinear mixed-effects modeling using 3801 and 2626 concentration data from 336 a...
The use of generic drugs after patent expiration of their originators is a relative novelty in the treatment of chronic cancer patients in Western countries. In this observational study we analyzed a cohort of 294 Italian chronic phase chronic myeloid leukemia patients treated frontline with branded imatinib (Glivec®) for at least 6 months and then uniformly switched to generic imatinib upon requirement of health authorities in early 2017. Median age at diagnosis was 57 years (range 19-87). Sokal risk was ...

In accordance with International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) guidelines, six novel, simple and precise sequential spectrophotometric methods were developed and validated for the simultaneous analysis of Ribavirin (RIB), Sofosbuvir (SOF), and Daclatasvir (DAC) in their mixture without prior separation steps. These drugs are described as co-administered for treatment of Hepatitis C virus (HCV). HCV is the cause of hepatitis C an...
The nucleotide analogues tenofovir and sofosbuvir are considered to have low potential for drug interactions.
There have been a few reports on the treatment of patients infected with recombinant hepatitis C virus (HCV) genotype 2/1 strains with direct-acting antivirals (DAAs). We experienced three patients, with genotype 2/1 recombinant HCV, treated with DAAs successfully. The first, a 39-year-old man, was infected with recombinant HCV genotype 2a/1b, a rare variant. The sequence of the relapsed virus showed chimeric HCV 2a/1b with the recombinant breakpoint found at nucleotide +49 from the start of the NS3 region....
Optional treatments for patients with chronic hepatitis C virus (HCV) genotype (GT) 6 infection have not been extensively studied. This study aimed to evaluate the safety and efficacy of sofosbuvir (SOF)-based direct-acting antiviral agents (DAAs) for HCV GT6. We performed a retrospective study at the West China Hospital of Sichuan University in Southwest China from January 2016 to May 2017. Our study screened 130 treatment-naïve patients with chronic HCV GT6 and without liver cirrhosis. A total of 60 HCV ...
Symptomatic bradycardia has been reported in adults treated for chronic hepatitis C using sofosbuvir based regimens.
Co-administration of sofosbuvir, an anti-hepatitis C virus medication, and antiarrhythmic amiodarone causes symptomatic severe bradycardia in patients and animal models. However, in a few in vitro studies, the combination of sofosbuvir and amiodarone resulted in tachycardiac effects in human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs). This discrepancy may be attributable to the use of immature hiPSC-CMs in the in vitro studies. To address this, we evaluated the ability of our in-house ...
