Description

DESCRIPTION

Sofosbuvir is related with the treatment of unending hepatitis C viral infection. Sofosbuvir isn't used as Monotherapy; it is used by joining with Velpatasvir Both the dynamic fragments are demonstrating movement against hepatitis contamination.

Sofosbuvir and Velpatasvir are doctor prescribed medications; it is used by the patient simply under the guaindance of restorative counsel (hepatologist).

Velasof is a doctor prescribed pharmaceutical; it is taken by the patients simply under the course of medicinal expert Velasof is a settled dosage blend calm, contains Sofosbuvir and Velpatasvir as a working fixings. Both the fragments show against viral activity. Velasof tablet is dynamic against contamination which causes hepatitis C illness in adults Velasof comprises of; Sofosbuvir-HCV NS5B polymerase inhibitor Velpatasvir-HCV NS5A inhibitor

VELASOF TABLETS WORKS

Sofosbuvir is a NS5B protein inhibitor; protein is essential for viral age. Sofosbuvir is a prodrug shape, which get changed over into dynamic uridine triphosphate outline which is required for against viral development. This dynamic moiety is getting implanted into HCV RNA with the help of NS5B polymerase and leads as chain eliminator. Velpatasvir is pharmacologically goes about as NS5A inhibitor; this protein is required for HCV viral age. Velpatasvir is incorporated its action in viral age process. The major mechanism of Velasof is involved in prohibition of viral production by intercedes the NS5A & NS5B proteins.

PHARMACOKINETIC

Maximum plasma concentration time: Sofosbuvir 0.5 to 1 hour & Velpatasvir 3 hours. Velasof should be given with food or without food. Human protein binding nature of Velasof : Sofosbuvir 61 to 65% & Velpatasvir >99.5% & the circulating metabolite of Sofosbuvir is GS-331007 has low binding effect.

Velasof metabolism occurs in liver, with the help of cathepsin A, carboxyl esterase 1for sofosbuvir; CYP2B6, CYP2C8 or CYP3A4 for Velpatasvir. Excretion of Velasof should be occurs through glomerular filteration & active tubular secretion & biliary excretion.

Sofosbuvir doses are eliminated via urine as 80%, feces as 14% & exhaled air as 2.5%. Velpatasvir doses are eliminated via urine as 0.4% & feces as 94%.

The half life period of Velasof is; Sofosbuvir 0.4 hour GS-331007: 27 hours Velpatasvir: 15 hours

Velpatasvir is hard to remove by dialysis process since it is uncommonly connections to human plasma protein. Sofosbuvir revolving around metabolites get abstained from through dialysis with extent of 53%.

THERAPY DURATION
PATIENTS WITH COMPENSATED CIRRHOSIS OR WITHOUT CIRRHOSIS

One tablet of Velasof should be administered orally as once daily over period of 12 weeks.

PATIENTS WITH DECOMPENSATED CIRRHOSIS

One Velasof tablet should be combined with weight based ribavirin by administering with food for 12 hours.

THE DOSE OF RIBAVIRIN SHOULD BE CALCULATED FOR THE PATIENTS

Patient with <75kg of body weight, the recommended dose of ribavirin is 1000mg administered as twice daily. Patient with at least 75kg of body weight, recommended dose of ribavirin is 1200mg administered as twice daily. For both renal & hepatic impaired patients; Velasof tablets dosage adjustment should not be recommended.

SIDE EFFECTS

UNFAVORABLE EFFECTS

Serious bradycardia occurs due to concomitant use of Velasof with amiodarone. Insomnia Irritability Headache Fatigue Nausea Asthenia

LAB ABNORMALITIES

Lipase elevation Elevation of creatine kinase Elevation of bilirubin levels

POST MARKETING EFFECTS

Cardiac disorders Rashes Angioedema

SAFETY MEASURES

BRADYCARDIA

This opposing occurs by mix of Velasof with amiodarone; causes extended joining of amiodarone prompts outrageous bradycardia. To overcome the issue by; Stop the combinational treatment ECG checking Start supportive medication for decreasing the cardiovascular issues

LOSS OF IMPACT BECAUSE OF BLEND OF VELASOF WITH P-GP INDUCERS

The synchronous use of Velasof with P-gp inducers causes loss of therapeutic activity of Velasof .

UTILIZATION OF RIBAVIRIN WITH VELASOF

Fetal mischief condition is a result of the orderly usage of Velasof with ribavirin in the midst of pregnancy period.

DRUG INTERACTION

The combination of Velasof with P-gp inducers potent produces lack of anti-viral activity due to diminished concentration of sofosbuvir. The co administration of Velasof with P-gp or BCRP inhibitors causes exposure of adverse effects associated with these substrates. The concurrent of Velasof with warfarin causes fluctuation in prothrombin time or INR values.

The co administration of Velasof with acid reducing agents should be avoided; this may causes loss of activity by reducing the concentration of ingredients in Velasof The combination of Velasof with amiodarone should be abstained. This combination causes bradycardia.

The concurrent use of Velasof with anti-convulsants or anti-mycobacterials causes diminishing the concentration of Velpatasvir or sofosbuvir.
