Description of Resof + Hepcfix - 12 weeks

Resof Hepcfix is containing an anti viral agent as active ingredients like Sofosbuvir & Daclatasvir.

Resof Hepcfix tablets are two medicine fixed dose combination with better anti-viral activity.

Resof Hepcfix is prescription medication which is used by patients with a valid prescription recommended by medical practitioner.

Resof Hepcfix are combination of two non structural proteins inhibitors like NS5A & NS5B, these proteins are responsible for viral production.

Resof-Sofosbuvir (uridine monophosphate analogue prohibitor of HCV polymerase

Hepcfix-Daclatasvir (HCV NS5A inhibitor)

Pharmacology of Resof + Hepcfix - 12 weeks

After oral administration of Resof Hepcfix tablets, it will undergo some mechanism for exhibiting the anti-viral activity. This may include as;

Sofosbuvir:

Generally sofosbuvir is an anti-viral medicine, which is occurred as prodrug gets converted into an active substance called as uridine triphosphate.

This active form of sofosbuvir is get intervened into viral RNA by HCV NS5B polymerase & acts as chain obstructor.

Daclatasvir:

Generally Daclatasvir is not used as monotherapy; it is combined with some other anti-viral agents like sofosbuvir for better anti-viral effects.

In this condition, Daclatasvir is pharmacologically considered as a HCV NS5A prohibitor.

After administration, the intracellular uptake of Daclatasvir into the site of NS5A protein occurs.

This binding leads to cause disruption of viral replication complex & concludes as blockade of viral HCV RNA production.

Pharmacokinetics of Resof Hepcfix

Absorption

After intake of Resof Hepcfix, absorption occurs very quickly & reaches its maximal plasma concentration time by;

Sofosbuvir: 0.5 to 1 hour & Daclatasvir: 2 hours

Then the absolute bioavailability of Daclatasvir occurs by 67%.

Distribution

After absorption, sofosbuvir is highly binds to human plasma protein by 61 to 65%.

Daclatasvir has broadly bound to protein by approximately 99%.

The apparent volume of distribution of Daclatasvir is occurs by 47L.

Metabolism

The metabolism of both anti-viral agents like Sofosbuvir & Daclatasvir occurs in liver majorly.

Sofosbuvir: cathepsin A, carboxyl esterase 1 or HINT 1

Daclatasvir: CYP3A4

Elimination

The elimination route of sofosbuvir is majorly by hepatic metabolism

Circulating metabolite of sofosbuvir GS-331007: glomerular filteration & active tubular secretion

Daclatasvir: biliary excretion

Sofosbuvir: 80% in urine, 14% in feces

Daclatasvir: 88% in feces, 6.6% in urine

The median terminal half life period of Resof Hepcfix;

Sofosbuvir: 0.4 hours; GS-331007: 27 hours

Daclatasvir: 12 to 15 hours

Indication of Resof + Hepcfix - 12 weeks

Resof Hepcfix tablets are widely used in the therapy of chronic hepatitis C viral infection associated with genotype I or III.

In chronic or decompensated cirrhosis (child Pugh B or C), Resof Hepcfix is used in combination of ribavirin.

There is a chance of losing virological response occurs, if patients with HCV genotype III with cirrhosis condition using Resof Hepcfix for 12 weeks.

Dose & Dosage's of Resof + Hepcfix - 12 weeks

Before begin the therapy with Resof Hepcfix, patients must be investigated thoroughly whether HBV infection suspected or not.

Check the HBsAg & anti-HBc levels for avoiding the condition like reoccurrence of HBV infection.

Hepatic function test should be taken frequently.

Recommended dosage;

For genotype I;

Without cirrhosis patients: The suggested dose is one tablet of Resof Hepcfix should be given orally as once daily.

Compensated cirrhosis patients: The suggested dose is one tablet of Resof Hepcfix should be administered orally as single dose.

Decompensated cirrhosis patients: The suggested dose is one tablet of Resof Hepcfix should be combined with ribavirin as once daily.

For genotype III;

Without cirrhosis patients: The suggested dose is one tablet of Resof Hepcfix should be given orally as once daily.

Compensated or decompensated cirrhosis: The suggested dose is one tablet of Resof Hepcfix should be combined with ribavirin as once daily

Dosage of ribavirin;

Patients with less than 75kg: 1000mg of ribavirin are recommended per day.

Patients with at least 75kg: 1200mg of ribavirin should be recommended (600mg two times a day).

Side Effects of Resof + Hepcfix - 12 weeks

Symptomatic bradycardia while combining with amiodarone

Increased bilirubin

Increased lipase

Headache

Fatigue

Nausea

Diarrhea

Insomnia

Dizziness

Somnolence

Anemia

Increased AST, ALT

Contraindication of Resof + Hepcfix - 12 weeks

Resof Hepcfix tablets are combined with ribavirin should be contraindicated to pregnancy & lactating women.

Some hypersensitivity reactions are formed while patients are contraindicated to the component of Resof Hepcfix tablets.

Drug Interaction of Resof + Hepcfix - 12 weeks

The combination of Resof Hepcfix with CYP3A inducers causes depletion of Daclatasvir plasma concentration.

The concurrent use of Resof Hepcfix with CYP3A inhibitors leads to cause increased Daclatasvir plasma concentration.

The co administration of Resof Hepcfix with P-gp or BCRP substrates leads to cause elevation of exposure of adverse effects associated to these substrates.

The concurrent use of Resof Hepcfix with warfarin causes changes in prothrombin time & INR values leads to bleeding defects.

Resof Hepcfix tablets co administered with protease inhibitors causes depletion of effect of concentration of Daclatasvir.

Resof Hepcfix tablets with amiodarone causes bradycardia.

Resof Hepcfix tablets are combined with lipid lowering agents causes increased concentration of these drugs.

Resof Hepcfix tablets combined with drugs like anti-convulsants or anti-mycobacterials causes loss of effect of concentration of sofosbuvir.

Resof Hepcfix with st Johns wort causes loss of therapeutic activity of the Resof or Hepcfix.

Precaution of Resof + Hepcfix - 12 weeks

HBV reactivation;

This fatal case is occurs majorly in the patients with HCV/HBV co infection.

HBV reactivation occurs in patients who are receiving anti-HCV agents & fail to receive anti-HBV agents.

Prevent the problem by;

Counting the HBsAg & anti-HBc levels

Monitor the hepatic function test

Initiate the management associated to HBV infection

 Loss of virological response;

This case is occurs due to combination of Daclatasvir with other anti-viral agents.

Prevent the condition by monitoring the patients frequently for identifying the resistance to the suspected virus.

Bradycardia;

This fatal case is occurs by combining the Resof Hepcfix tablets with amiodarone.

Avoid this combination

Monitor the ECG

Counsel the patients before begin the therapy about the risk associated with these combination treatment.

Initiate the alternative measurements for reducing the cardiac related issues.
