There are multiple interactions reported between these two agents.

Interaction Details

Ombitasvir, Paritaprevir Ritonavir is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, Panax ginseng might increase or decrease levels of drugs metabolized by CYP3A4.
Panax ginseng may affect the clearance of drugs metabolized by CYP3A4. One such drug is imatinib. Inhibition of CYP3A4 was believed to be responsible for a case of imatinib-induced hepatotoxicity. In contrast, Panax ginseng has been shown to increase the clearance of midazolam, another drug metabolized by CYP3A4. Clinical research shows that Panax ginseng can reduce midazolam area under the curve by 44%, maximum plasma concentration by 26%, and time to reach maximum plasma concentration by 29%. Midazolam metabolism was also increased in animals given Panax ginseng. Until more is known, use Panax ginseng cautiously in combination with CYP3A4 substrates.

Interaction Rating

Moderate

Likelihood of Occurrence

Possible

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists

Interaction Details

Ombitasvir, Paritaprevir Ritonavir is classified as belonging to the following category: Lopinavir/Ritonavir (Kaletra)

Although Panax ginseng has demonstrated variable effects on cytochrome P450 3A4 (CYP3A4), which metabolizes lopinavir, Panax ginseng is unlikely to alter levels of lopinavir/ritonavir.
Lopinavir is metabolized by CYP3A4 and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Panax ginseng has shown variable effects on CYP3A4 activity in humans. However, taking Panax ginseng (Vitamer Laboratories) 500 mg twice daily for 14 days did not alter the pharmacokinetics of lopinavir/ritonavir in 12 healthy volunteers.

Likelihood of Occurrence

Unlikely

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Panax Ginseng Overview

Panax Ginseng Panax ginseng is commonly referred to as 'Asian ginseng' and is not to be confused with 'American Ginseng'. It is a slow-growing plant native to eastern Asia and has been used for a variety of purposes, including to boost energy and improve overall health. The root of the Panax ginseng plant is the part that is typically used in medicine. Panax ginseng is often classified as an 'adaptogen', which is theorized to help the body adapt to stress, both physical and psychological.

Ombitasvir, Paritaprevir Ritonavir Overview

  • The combination of ombitasvir, paritaprevir, and ritonavir is usually used in combination with ribavirin (Copegus, Rebetol), but sometimes it is used alone to treat a certain type of chronic (long-term) hepatitis C infection (swelling of the liver caused by a virus). Ombitasvir is a hepatitis C virus (HCV) NS5A inhibitor. It works by stopping the virus that causes hepatitis C from spreading inside the body. Paritaprevir is a protease inhibitor. It works by decreasing the amount of HCV in the body. Ritonavir is a protease inhibitor. It helps to increase the amount of paritaprevir in the body so that the medication will have a greater effect. It is not known if ombitasvir, paritaprevir, or ritonavir prevent the spread of hepatitis C to other people.
