      introduce

      Sofosbuvir is a potent oral nucleotide analogue and core antiviral API, acting as a selective inhibitor of HCV NS5B RNA-dependent RNA polymerase. It is a prodrug metabolized to the active triphosphate form, blocking hepatitis C virus (HCV) replication. Approved for chronic HCV infection.

      Our products comply with strict international standards to ensure high purity, stable efficacy, and reliable supply.

      Physical and chemical properties

      Sofosbuvir exhibits key physical and chemical characteristics supporting its pharmaceutical and research applications, as follows:

      - Melting Point: 122-124 °C
      - Density: 1.4±0.1 g/cm³
      - Solubility: Slightly soluble in DMSO and methanol
      - Storage Temperature: Hygroscopic; store at -20 °C in a freezer under inert atmosphere

      Advantages 

      1. More convenient administration
      It is the world's first oral drug for hepatitis C, no injection required. It allows some hepatitis C patients to get rid of the dependence on interferon, filling the gap in oral anti-hepatitis C treatment.

      2. Remarkable inhibitory effect
      It can rapidly reduce the hepatitis C virus load in the body and achieve more than 99% viral inhibition in a short time. Compared with some hepatitis C drugs with slow onset, it can control viral replication much faster.

      3. Low drug resistance risk
      It has a high genetic barrier to drug resistance, and basically no drug-resistant variants appear when used in combination with other hepatitis C drugs; a small amount of mild drug resistance is occasionally seen only when used as monotherapy, and these drug-resistant viral strains are still sensitive to other hepatitis C drugs, it is more stable for long-term treatment.

      4. Wide application range
      It can be used to treat hepatitis C virus genotypes 1 to 6. Compared with hepatitis C drugs that can only treat a few genotypes, it is suitable for more hepatitis C patients with different genotypes.

      5. Good targeting and combination therapy
      As a prodrug, it is metabolized into an active form to exert its effect only in the liver, acting on the lesion site accurately with little impact on normal human cells; it can also be used in combination with a variety of hepatitis C drugs, and different treatment regimens can be matched according to patients' conditions.

      Application

      It is mainly used for the treatment of chronic hepatitis C virus (HCV) infection and is a first-line drug for hepatitis C treatment. The specific application scenarios include:

      1. Combined with other drugs (ribavirin, velpatasvir, NS5A inhibitors, etc.) for the treatment of patients with chronic HCV genotype 1-6 infections, which is the clinical preferred combination therapy regimen.

      2. Used in interferon-free hepatitis C treatment regimens, it can replace traditional interferon injection and is suitable for hepatitis C patients who are intolerant or ineligible for interferon.

      3. Used for hepatitis C patients with hepatocellular carcinoma (HCC) awaiting liver transplantation, and antiviral treatment for such patients can be carried out for up to 48 weeks to delay disease progression.
