Пирфенидон

Описание

Until recently, IPF therapy consisted of a combination of corticosteroids and immunosuppressive agents (azathioprine and cyclophosphamide) to target the inflammation that was believed to be the pathogenic stimulus.Since IPF is now considered to be predominantly a disorder of fibroproliferation, agents that intervene in fibrogenesis have moved to the forefront of treatment options. With demonstrated efficacy in a bleomycin-induced lung fibrosis animal model, pirfenidone has been developed and launched as an approved therapy for IPF. Its antifibrotic activity is derived from the inhibition of p38 MAP kinase that is upstream of transforming growth factor-β (TGF-β), a cytokine implicated in the stimulation of collagen synthesis and the inhibition of its degradation. Pirfenidone also inhibits the expression of TNF-α, IL-1, and ICAM-1, so it possesses the dual benefit of an anti-inflammatory and antifibrotic agent. This relatively simplistic drug is constructed by the copper-catalyzed reaction of 5-methyl-2(1H)-pyridinone with bromo- or chlorobenzene. .

Использование

Pirfenidone is in a group of medicines called antifibrotic agents. Pirfenidone has demonstrated activity in multiple fibrotic conditions, including those of the lung, kidney and liver. It affects your body’s immune system and reduces the amount of fibrosis (scarring) in the lungs. Pirfenidone is one of two medicines that are approved in Canada to treat Idiopathic Pulmonary Fibrosis (IPF). Another name for this medicine is Esbriet.
