The active substance is pirfenidone.
Drugs such as pirfenidone and nintedanib are often used.
Concomitant treatment with pirfenidone.
The mechanism of action of pirfenidone has not been fully established.
Each film-coated tablet contains 534 mg pirfenidone.
Esbriet(pirfenidone)- Summary of product characteristics- L04AX05.
Co-administration with pirfenidone.
Esbriet(pirfenidone)- Conditions or restrictions regarding supply and use- L04AX05.
NAME OF THE MEDICINAL PRODUCT Esbriet 267 mg hard capsules Pirfenidone.
The absolute bioavailability of pirfenidone has not been determined in humans.
Pirfenidone binds to human plasma proteins, primarily to serum albumin.
Nintedanib had no effect on the PK of pirfenidone(see section 4.4).
No dose adjustment is required in patients with mild renal impairment who are receiving pirfenidone.
Pirfenidone helps to slow the development of scarring in the lungs by reducing the activity of the immune system.
The benefit-risk balance of concomitant treatment with pirfenidone has not been established.
Adverse reactions were mild, transient, andconsistent with the most frequently reported adverse reactions for pirfenidone.
When tested under UV exposure pirfenidone was positive in a photoclastogenic assay in Chinese hamster lung cells.
In subjects with moderate hepatic impairment(i.e. Child-Pugh Class B), pirfenidone exposure was increased by 60%.
Approximately 70-80% of pirfenidone is metabolised via CYP1A2 with minor contributions from other CYP isoenzymes including CYP2C9, 2C19, 2D6, and 2E1.
Consumption of grapefruit juice is associated withinhibition of CYP1A2 and should be avoided during treatment with pirfenidone.
Two drugs approved for IPF,nintedanib and pirfenidone, offer promise for improving health outcomes and survival during the course of the disease.
A Phase 1 interaction study evaluated the effect of cigarette smoking(CYP1A2 inducer)on the pharmacokinetics of pirfenidone.
Following single dose administration of pirfenidone in healthy older adults, the mean apparent terminal elimination half-life was approximately 2.4 hours.
In a dedicated pharmacokinetic study, concomitant treatment of nintedanib with pirfenidone was investigated in patients with IPF.
Patients should be encouraged to discontinue use of strong inducers of CYP1A2 andto stop smoking before and during treatment with pirfenidone.
In animals placental transfer of pirfenidone and/or its metabolites occurs with the potential for accumulation of pirfenidone and/or its metabolites in amniotic fluid.
In the case of moderate inducers of CYP1A2(e.g. omeprazole),concomitant use may theoretically result in a lowering of pirfenidone plasma levels.
Results showed that there was a mean increase of 60% in pirfenidone exposure after a single dose of 801 mg pirfenidone(3 x 267 mg capsule) in patients with moderate hepatic impairment.
Other therapies that are inhibitors of both CYP1A2 andone or more other CYP isoenzymes involved in the metabolism of pirfenidone.
The majority of pirfenidone is excreted as the 5-carboxy-pirfenidone metabolite(>95% of that recovered), with less than 1% of pirfenidone excreted unchanged in urine.
