APIs for research and impurities

Roflumilast is a drug used to treat chronic obstructive pulmonary disease. It is also used to treat inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis. Roflumilast inhibits the enzyme cytochrome P450 in the liver, which is responsible for metabolizing certain drugs and other substances. This inhibition reduces the metabolism of these substances, leading to increased levels of these substances in the body. This can lead to side effects such as nausea, vomiting, dizziness, headache, and itching. Roflumilast also has an anti-inflammatory effect on the intestines by regulating the production of inflammatory cytokines and inhibiting the activity of pro-inflammatory enzymes.
