Delta-9-tetrahydrocannabinol (thc) Overview
Delta-9-tetrahydrocannabinol (THC), also known as tetrahydrocannabinol, is a cannabinoid. It is one of the over 80 constituents, known as cannabinoids, that have been identified from Cannabis sativa. THC is the major psychoactive compound of cannabis and is most often associated with the plant's recreational use. THC is known to produce a range of effects on the body and mind, including relaxation, altered senses, and changes in mood and cognition. THC has also been used to treat pain and anxiety symptoms.
Rifapentine Overview
-
Rifapentine is used with other medications to treat active tuberculosis (TB; a serious infection that affects the lungs and sometimes other parts of the body) in adults and children 12 years of age and older. Rifapentine is also used with isoniazid (Laniazid) to treat adults and children 2 years of age and older with latent (resting or nongrowing) TB, including those in close contact with people who have active TB, a positive tuberculin skin test, human immunodeficiency virus (HIV), or those with pulmonary fibrosis (scarring of the lungs with an unknown cause). Rifapentine is in a class of medications called antimycobacterials. It works by killing the bacteria that cause infection.
-
Antibiotics such as rifapentine will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
