Hepcvir-12weeks-Sofosbuvir - Tablets


STRENGTH : Sofosbuvir 400mg


HEPCVIR(SOFOSBUVIR 400MG) Hepcvir(Sofosbuvir 400mg) is a prescription medicine used with other antiviral medicines to treat adults with chronic hepatitis C (Hep C) with or without cirrhosis (compensated).

Hepcvir recommended with some combination of ribavirin, peginterferon-alfa, simeprevir, ledipasvir, daclatasvir, or velpatasvir to cure genotype 1 to 6 infections. Cure rates are 30 to 97% depending on the type of hepatitis C virus involved. Hepcviris safe and effective in patient who have had a liver transplant.

Hepcvir(Sofosbuvir 400mg) is activated in the liver to the triphosphate GS-461203 by hydrolysis of the carboxylate ester by either of the enzymes cathepsin A or carboxylesterase 1, followed by cleaving of the phosphoramidate by the enzyme histidine triad nucleotide-binding protein 1 (HINT1), and subsequent repeated phosphorylation. Dephosphorylation creates the inactive metabolite GS-331077. The half life of Hepcvir is 0.4 hours, and the half life of GS-331007 is 27 hours. Following a single 400 mg oral dose of Hepcvir, 80% is excreted in urine, 14% in feces, and 2.5% in expired air recovery.

However, of the urine recovery 78% was the metabolite (GS-331007) and 3.5% was Hepcvir Hepcvir(Sofosbuvir 400mg) has a number of ideal properties, once daily dosing, no meal restrictions, few adverse effects, minimal drug-drug interactions, high genetic barrier to resistance, good safety and efficacy in patients with advanced liver disease, and excellent sustained virologic response rates in patients with unfavorable baseline characteristics Hepcvir(Sofosbuvir 400mg) (in combination with ledipasvir, daclatasvir or simeprevir) should not be used with amiodarone due to the risk of abnormally slow heartbeats.

Hepcvir(Sofosbuvir 400mg) is a substrate of P-glycoprotein, a transporter protein that pumps drugs and other substances from intestinal epithelium cells back into the gut. Therefore, inducers of intestinal P-glycoprotein, such as rifampicin and St. John's wort, could reduce the absorption of Hepcinat. In addition, coadministration of Hepcvirwith anticonvulsants (carbamazepine, phenytoin, phenobarbital, oxcarbazepine), antimycobacterials (rifampin, rifabutin, rifapentine), and the HIV protease inhibitor tipranavir and ritonavir is expected to decrease Hepcvirconcentration. Thus, coadministration is not recommended. The interaction between Hepcvir and a number of other drugs, such as ciclosporin, darunavir/ritonavir, efavirenz, emtricitabine, methadone, raltegravir, rilpivirine, tacrolimus, or tenofovir disoproxil, were evaluated in clinical trials and no dose adjustment is needed for any of these drugs. Common side effects include feeling tired, headache, nausea, and trouble sleeping.

Side effects are generally more common in interferon-containing regimens. Hepcvir may reactivate hepatitis B in those who have been previously infected. In combination with ledipasvir, daclatasvir or simeprevir it is not recommended with amiodarone due to the risk of an abnormally slow heartbeat. Hepcvir(Sofosbuvir 400mg) alone has been assigned a Pregnancy Category B by the FDA (meaning that it there are no adequate and well-controlled studies in pregnant women but animal reproduction studies have not demonstrated a risk to the fetus and, or that adverse effects have been seen in animal studies, but adequate and well-controlled studies in pregnant women have not, in any trimester).

However, ribavirin, a medication that is often given together with Hepcvirto treat hepatitis C, is assigned a Pregnancy Category X (contraindicated in pregnancy) by the FDA. Pregnant women with hepatitis C who take ribavirin have shown some cases of birth defects and death in their fetus.

It is recommended that Hepcvir/ribarivin combinations be avoided in pregnant females and their male sexual partners in order to reduce harmful fetal defects caused by ribavirin. Females who could potentially become pregnant should undergo a pregnancy test 2 months prior to starting the Hepcvir/ribavirin/peginterferon combination treatment, monthly throughout the duration of the treatment, and 6 months post-treatment to reduce the risk of fetal harm in case of accidental pregnancy.

It is unknown whether Hepcvirand ribavirin pass into breastmilk; therefore, it is recommended that the mother does not breastfeed during treatment with Hepcviralone or in combination with ribavirin. Hepcvir( Sofosbuvir ) is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.
