🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionSofosbuvir is rapidly absorbed after oral administration, with peak plasma concentrations reached in about 0.5 to 2 hours. Velpatasvir is also well absorbed, with peak levels at about 3 hours. Food does not significantly affect absorption, so it can be taken with or without food.
DistributionBoth drugs are highly bound to plasma proteins. Sofosbuvir is approximately 61-65% bound, while velpatasvir is more than 99% bound. They distribute widely into tissues, including the liver, which is the site of action.
Protein BindingSofosbuvir is about 61-65% bound to human plasma proteins. Velpatasvir is greater than 99% bound.
MetabolismSofosbuvir is metabolized in the liver to its active triphosphate form and then to inactive metabolites. Velpatasvir is metabolized primarily by CYP2B6, CYP2C8, and CYP3A4 enzymes.
Half-LifeThe elimination half-life of sofosbuvir is approximately 0.4 hours for the parent drug and 27 hours for the active metabolite. Velpatasvir has a half-life of about 15 hours.
ExcretionSofosbuvir and its metabolites are excreted mainly in urine (about 80%) and feces (about 14%). Velpatasvir is excreted primarily in feces (about 94%) and minimally in urine.
BioavailabilityThe absolute bioavailability of sofosbuvir is approximately 60-70%. The bioavailability of velpatasvir is not well established but is considered high.
Onset of ActionViral load begins to drop within days of starting treatment, but the full therapeutic effect (cure) is assessed 12 weeks after completing therapy.
Peak Plasma TimeSofosbuvir reaches peak plasma levels in about 0.5 to 2 hours. Velpatasvir reaches peak levels in about 3 hours.
Duration of ActionThe standard treatment duration is 12 weeks. The effect persists after stopping the medicine, as the goal is a sustained virologic response.

How It Works

This medicine combines two direct-acting antivirals that target different steps of the hepatitis C virus life cycle. Sofosbuvir is a prodrug that is converted inside cells to an active nucleotide analogue that inhibits the NS5B RNA-dependent RNA polymerase, causing chain termination and blocking viral replication. Velpatasvir is an NS5A inhibitor that binds to the NS5A protein, which is essential for viral RNA replication and assembly of new virus particles. Together, they reduce viral load and can lead to a sustained virologic response, which is considered a cure.

Mechanism Steps

1
Sofosbuvir activation: Sofosbuvir enters liver cells and is converted to its active triphosphate form, which competes with natural nucleotides.
2
NS5B inhibition: The active form of sofosbuvir binds to the NS5B polymerase and incorporates into viral RNA, causing chain termination and stopping viral replication.
3
Velpatasvir binding: Velpatasvir binds to the NS5A protein, disrupting its role in viral RNA replication and virion assembly.
4
Viral suppression: The combined action reduces HCV RNA levels, preventing the virus from multiplying and allowing the immune system to clear infected cells.
5
Sustained virologic response: After completing therapy, if HCV RNA remains undetectable for 12 weeks, the patient is considered cured.

Dosage Information

Adult DosageThe recommended dose for adults is one tablet (sofosbuvir 400 mg + velpatasvir 100 mg) taken orally once daily for 12 weeks.

Dose must be individualized by a qualified clinician based on indication, genotype, cirrhosis status, and renal function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageNo dose adjustment is required for elderly patients based on age alone. However, because elderly patients may have decreased renal or hepatic function, monitor closely and adjust as needed.
Renal ImpairmentNo dose adjustment is needed for patients with mild to moderate renal impairment. For patients with severe renal impairment (eGFR <30 mL/min) or on dialysis, use with caution; no specific dose recommendations are established.
Hepatic ImpairmentNo dose adjustment is needed for patients with mild to moderate hepatic impairment (Child-Pugh A or B). For patients with severe hepatic impairment (Child-Pugh C), use is not recommended unless under specialist supervision.

Inform your doctor about all other medicines, including over-the-counter drugs and herbal supplements, because many interact with this medicine. Use effective contraception during treatment if you are of childbearing potential. Avoid alcohol to protect your liver. Keep all follow-up appointments for blood tests to monitor viral response and liver function. Store at room temperature away from moisture and heat.

👴 Special Considerations for Elderly

💡 For Patients Above 65

Elderly patients may have reduced renal or hepatic function. No dose adjustment is required based on age alone, but monitor closely for side effects and drug interactions. Ensure adequate hydration and nutrition.

🤰 Pregnancy Planning (TTC)

If you are planning to become pregnant, discuss with your doctor before starting this medicine. Effective contraception is recommended during treatment for both men and women. The safety of this medicine in pregnancy is not well established.

🌞
Get vaccinated against hepatitis A and B if not already immune.
🚭
Manage stress through relaxation techniques like yoga or meditation.

🏋️ Exercise Considerations

Moderate exercise is generally safe, but if you experience fatigue or dizziness, reduce intensity. Avoid strenuous activities if you have advanced liver disease or low platelet counts. Consult your doctor before starting a new exercise regimen.

🥗 Diet Recommendations

Include plenty of fruits and vegetables.
Choose lean proteins like fish, poultry, and beans.
Limit processed foods, sugary drinks, and saturated fats.
Stay well hydrated by drinking plenty of water.

💼 Impact on Daily Work & Life

Most people can continue their normal work and daily activities while taking this medicine. If you experience fatigue or dizziness, avoid driving or operating heavy machinery until you know how the medicine affects you. Treatment is usually well tolerated, and serious side effects are rare.

🛑 When to Stop This Medicine

Do not stop taking this medicine without consulting your doctor. If you experience severe side effects or a serious allergic reaction, stop the medicine and seek immediate medical attention. Your doctor will decide if treatment should be discontinued or adjusted.

📅 Long-Term Use Effects

Long-term effects after completing treatment are generally positive, as the medicine aims to cure hepatitis C.

However, patients with existing cirrhosis should continue regular liver monitoring even after cure. There are no known long-term side effects from the medicine itself after treatment ends.

🌿 Non-Medicine Approaches

These can complement medicine but do not replace prescribed treatment.

Other direct-acting antiviral regimens

Alternative combinations like sofosbuvir/ledipasvir or glecaprevir/pibrentasvir may be used based on genotype and clinical factors.

Evidence: Well-established
Lifestyle modifications

Avoiding alcohol, maintaining a healthy diet, and regular exercise support liver health during and after treatment.

Evidence: Well-established

💉 Vaccination Considerations

💉 If You're Getting Vaccinated
