Optical Activity UNSPECIFIED

Paritaprevir is a potent inhibitor of the NS3/4A protease that rapidly and consistently suppresses HCV. Paritaprevir is metabolized by the Cytochrome P450 isoform 3A (CYP3A); therefore, ritonavir was used concurrently to increase plasma concentrations and to prolong the half-life of this agent allowing for once-daily dosing. Several antiviral regimens combining paritaprevir with other agents have shown impressive results, tolerable side effects, and importantly, provided support of ‘all-oral’ interferon-free regimens against HCV. Paritaprevir monotherapy is discontinued now but paritaprevir is used as a component of Viekira Pak and Technivie for the treatment of patients with genotype 1 chronic hepatitis C virus (HCV) infection.

Approved Use

TECHNIVIE is a fixed-dose combination of ombitasvir, a hepatitis C virus NS5A inhibitor, paritaprevir, a hepatitis C virus NS3/4A protease inhibitor, and ritonavir, a CYP3A inhibitor and is indicated in combination with ribavirin for the treatment of patients with genotype 4 chronic hepatitis C virus (HCV) infection without cirrhosis or with compensated cirrhosis.

Sample Use Guides

50, 100 and 200 mg daily for 3 days (each dose in combination with 100 mg ribavirin).
Route of Administration: Oral
To determine the breadth of coverage in genotype 1, the activity of Paritaprevir against chimeric replicons containing sequences derived from 11 genotype 1a- and 9 genotype 1b-infected patients was characterized. EC50s ranged from 0.43 to 1.87 nM against the genotype 1a isolates and from 0.033 to 0.087 nM against the genotype 1b isolates, indicating that Paritaprevir can inhibit NS3 proteases across a broad range of genotype 1 isolates.
