What It Is and How It Works
Ivermectin
Ivermectin is a medication primarily used to treat a variety of parasitic infections. It belongs to a class of anti-parasitic drugs known as avermectins, which help in crippling the ability of parasites to reproduce and affect the host.
Paxlovid
Paxlovid, on the other hand, is a dual-component antiviral medication designed to reduce the severity of COVID-19 infections. It’s composed of nirmatrelvir, which inhibits viral protease enzymes, preventing viral replication, and ritonavir, which boosts the efficacy of nirmatrelvir by slowing its breakdown in the liver.
Indications / Uses
Ivermectin
