Comparison of Beneficial Actions of Non-steroidal Anti-inflammatory Drugs To Flavonoids

Inflammation is involved in increasing number of diseases necessitating the development of new, effective and safe treatments. Non steroidal anti-inflammatory drugs (NSAIDs) have been helpful in many instances, but they only inhibit cyclooxygenase (COX), but not the generation or actions of cytokines. Instead, some natural flavonoids have multiple anti-inflammatory effects, including COX inhibition, and a much safer profile. Increasing evidence indicates that inflammation plays a critical role in the pathogenesis of many diseases that also involve mast cells (1-3) (Table I). Consequently, the need for new, effective and safe anti-inflammatory drugs is all the more urgent. Corticosteroids are quite potent, but have many adverse effects such as increased risk of infections, osteoporosis, glaucoma and depression (4-8). Biological agents such anti-TNF are useful in certain conditions, such as rheumatoid arthritis and psoriasis, but has been associated with increased risk of infection and leukemia.
