Cannabis Overview
Cannabis, also known as marijuana, is a plant that contains more than 100 compounds known as cannabinoids. Some of these compounds can have psychoactive effects when consumed, which is why cannabis is often used for recreational purposes. However, cannabis has also been used for medicinal purposes and specific compounds found in cannabis (e.g., THC, CBD, CBN) are thought to have different effects and work on different receptors in the body. The two main cannabinoids in cannabis that are used medicinally are tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is the psychoactive compound in cannabis, while CBD is not psychoactive. Cannabidiol (CBD) is also found in the prescription drug Epidiolex and is used to treat certain types of seizures.
Cobicistat Overview
-
Cobicistat is used to increase the amounts of atazanavir (Reyataz, in Evotaz ) in adults and children weighing at least 77 pounds (35 kg) or darunavir (Prezista, in Prezcobix ) in adults and children weighing at least 88 pounds (40 kg) in the blood when these medications are used to treat human immunodeficiency virus (HIV). Cobicistat is in a class of medications called pharmacokinetic boosters. It works by increasing the amount of atazanavir or darunavir in the body so that they can have a greater effect.
