Information
| name: | FormoterolGlycopyrroniumBromideAndBeclometasone | |
| ATC code: | R03AL09 | route: | inhalation |
| compartments: | 1 | |
| dosage: | 400 | mg |
| volume of distribution: | 20 | L |

| other parameters in model implementation | ||
A fixed triple combination inhalation therapy consisting of formoterol (a long-acting beta-2 adrenergic agonist), glycopyrronium bromide (a long-acting muscarinic antagonist), and beclometasone (an inhaled corticosteroid) used for maintenance treatment of asthma and COPD in adults when combination therapy is appropriate. Approved and marketed for use in the EU and various other countries.
Pharmacokinetics
Pharmacokinetic estimates for healthy adult individuals after inhalation; no direct published clinical population PK studies exist for the triple fixed-dose combination. Model parameters are estimated based on available summary pharmacokinetics for each component in fixed-dose combination inhalers.
