{{/items}} {{^items}}Description
Fluticasone furoate is a synthetic trifluorinated corticosteroid with potent anti-inflammatory activity. Despite the similarity in the names, fluticasone furoate and fluticasone propionate are different drugs with different properties. It is marketed under the brand name, Veramyst in the US by GlaxoSmithKline for the management of chronic obstructive pulmonary disease (COPD). FDA approved on April 27, 2007. Fluticasone furoate is available as a combination product with vilanterol, a long-acting beta-2 agonist, under the tradename Breo Ellipta. Approved by the FDA in 2013, its use is indicated for the long-term, once-daily maintenance treatment of airflow obstruction in patients with COPD, including chronic bronchitis and emphysema. It is also indicated for once-daily maintenance treatment of asthma in patients aged 18 or older with reversible obstructive airways disease.
Indication
Fluticasone furoate nasal spray is indicated for the treatment of the symptoms of seasonal and perennial allergic rhinitis in patients aged 2 years and older. Breo Ellipta, a mixture of fluticasone furoate and vilanterol is indicated for the long-term, once-daily maintenance treatment of airflow obstruction in patients with COPD, including chronic bronchitis and emphysema. It is also indicated for once-daily maintenance treatment of asthma in patients aged 18 or older with reversible obstructive airways disease. Breo Ellipta should not be used for the relief of acute symptoms of asthma or COPD.
Mechanism of Action
Fluticasone furoate is a synthetic trifluorinated corticosteroid with potent anti-inflammatory activity. The precise mechanism through which fluticasone furoate affects rhinitis symptoms is not known. Corticosteroids have been shown to have a wide range of actions on multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, cytokines) involved in inflammation. Specific effects of fluticasone furoate demonstrated in in vitro and in vivo models included activation of the glucocorticoid response element, inhibition of pro-inflammatory transcription factors such as NFkB, and inhibition of antigen-induced lung eosinophilia in sensitized rats. Fluticasone is also found to increase airway retention of long-acting beta adrenergic agonist, thus potentiating its beneficial effects for the treatment of asthma.
Pharmacokinetics
- Absorption
- Following intranasal administration of fluticasone furoate, most of the dose is eventually swallowed and undergoes incomplete absorption and extensive first-pass metabolism in the liver and gut, resulting in negligible systemic exposure. Even at the highest recommended intranasal dose of 110 mcg once daily, plasma concentrations were not quantifiable. This is an especially useful feature as it lowers the incidence of adverse events associated with corticosteroid use. If administered using oral solution and intravenous dosing, 30% of the drug is absorbed and rapidly cleared from the plasma. Absolute bioavailability, intranasal route = 0.5%; Absolute bioavailability, oral route = 1.26%; Mean lung absorption time = 7 hours (regardless of formulation);
- Distribution
- Steady state, IV administration = 608 L
- Metabolism
- Fluticasone furoate does not undergo cleavage into its two separate components, fluticasone and the furoate moiety. It undergoes extensive hepatic metabolism via CYP3A4. The principal route of metabolism is hydrolysis of the S-fluoromethyl carbothioate function to form the inactive 17β-carboxylic acid metabolite. Studies suggest that enterocytes may be involved in the metabolism of unabsorbed drug.
- Elimination
Clearance
Total plasma clearance = 58.7 L/h
Toxicity
The most common adverse reactions (>1% incidence) included headache, epistaxis, pharyngolaryngeal pain, nasal ulceration, back pain, pyrexia, and cough.

Description
Umeclidinium is a long-acting muscarinic antagonist (LAMA) used as maintenance treatment for symptoms of chronic obstructive pulmonary disease (COPD). It is available as a once-daily inhalation monotherapy or as a fixed-dose combination product with the long-acting beta2-agonist vilanterol. COPD is a progressive obstructive lung disease characterized by shortness of breath, cough, sputum production, and chronically poor airflow with a forced expiratory volume in 1 second (FEV1) of less than 80%. By blocking the M3 muscarinic receptor which is highly expressed in airway smooth muscle of the lungs, umeclidinium inhibits the binding of acetylcholine and thereby opens up the airways by preventing bronchoconstriction. Its use has been shown to provide clinically significant, sustained improvements in lung function.
Indication
Indicated for the long-term, once-daily, maintenance treatment of airflow obstruction in patients with chronic obstructive pulmonary disease (COPD).
Mechanism of Action
Umeclidinium is a long-acting, antimuscarinic agent, which is often referred to as an anticholinergic. It has similar affinity to the subtypes of muscarinic receptors M1 to M5. In the airways, it exhibits pharmacological effects through the inhibition of M3 receptor at the smooth muscle leading to bronchodilation.
Pharmacokinetics
- Absorption
- Cmax occurred at 5 to 15 minutes, with steady state concentrations arriving in 14 days with 1.8-fold accumulation.
- Distribution
- Mean volume of distribution was 86 L.
- Metabolism
- In vitro data showed that umeclidinium is primarily metabolized by the enzyme cytochrome P450 2D6 (CYP2D6) and is a substrate for the P-glycoprotein (P-gp) transporter. The primary metabolic routes for umeclidinium are oxidative (hydroxylation, Odealkylation) followed by conjugation (e.g., glucuronidation), resulting in a range of metabolites with either reduced pharmacological activity or for which the pharmacological activity has not been established. Systemic exposure to the metabolites is low.
- Elimination
Toxicity
In clinical trials, the most common adverse effects of umeclidinium were nasopharyngitis, upper respiratory tract infection, cough, and arthralgia. Atrial fibrillation occurred in

Description
Vilanterol is a selective long-acting beta2-adrenergic agonist (LABA) with inherent 24-hour activity for once daily treatment of COPD and asthma. Its pharmacological effect is attributable to stimulation of intracellular adenylyl cyclase which catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3',5'-adenosine monophosphate (cAMP). Increases in cyclic AMP are associated with relaxation of bronchial smooth muscle and inhibition of release of hypersensitivity mediators from mast cells in the lungs. Vilanterol is approved for use in several combination products such as with fluticasone furoate under the tradename Breo Ellipta and in combination with umeclidinium bromide as Anoro Ellipta. Approved by the FDA in 2013, use of Breo Ellipta is indicated for the long-term, once-daily maintenance treatment of airflow obstruction in patients with COPD, including chronic bronchitis and emphysema. It is also indicated for once-daily maintenance treatment of asthma in patients aged 18 or older with reversible obstructive airways disease.

Pharmacokinetics
- Absorption
- Peak plasma concentrations are achieved within 10 minutes of inhalation. Absolute bioavailability was found to be 27.3% when administered by inhalation, whereas oral bioavailability was found to be less than 2% due to extensive first-pass metabolism. Systemic exposure is 24% higher in patients with COPD as compared to healthy subjects.
- Distribution
- Following IV administration to healthy subjects, the mean volume of distribution at steady state was 661 L.
- Metabolism
- Vilanterol is principally metabolized by cytochrome p450 3A4 (CYP3A4) to a range of metabolites with significantly reduced beta1- and beta2-agonist activity. The major route of metabolism was via O-dealkylation, with up to 78% of the recovered dose eliminated as O-dealkylated metabolites while N-Dealkylation and C-dealkylation were minor pathways, representing 5% of the recovered dose.
