Revinty Ellipta (Fluticasone_Vilanterol)

Uses

Fluticasone propionate is a glucocorticoid used to treat asthma, inflammatory pruritic dermatoses, and nonallergic rhinitis.

Fluticasone propionate is indicated as an inhaler for the treatment and management of asthma by prophylaxisas well as inflammatory and pruritic dermatoses. Fluticasone propionate nasal spray is indicated for managing allergic and nonallergic rhinitis.

Vilanterol is a long-acting beta2-adrenergic agonist used in combination with other bronchodilators for the management of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema.

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.

Revinty Ellipta (Fluticasone_Vilanterol) is also used to associated treatment for these conditions: Allergic Rhinitis (AR), Allergy to Mold, Allergy; Dander, Asthma, Bacterial Sinusitis, Chronic Bronchitis, Chronic Obstructive Pulmonary Disease (COPD), Chronic Sinusitis, Dermatitis, Emphysema, House Dust Mite Allergy, House dust allergy, Itching of the nose, Nasal Congestion, Nonallergic Rhinitis, Oesophagitis, Eosinophilic, Perennial Rhinitis, Pollen Allergy, Rhinitis, Rhinorrhoea, Seasonal Allergic Rhinitis, Sneezing, Moderate, severe Perennial Allergic Rhinitis (PAR), Moderate, severe Seasonal Allergic RhinitisAsthma, Chronic Obstructive Pulmonary Disease (COPD)

How Revinty Ellipta (Fluticasone_Vilanterol) works

Fluticasone propionate works through an unknown mechanism to affect the action of various cell types and mediators of inflammation. Fluticasone propionate activates glucocorticoid receptors and inhibits lung eosinophilia in rats.

Vilanterol is a selective long-acting beta2-adrenergic agonist. 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.

Toxicity

Fluticasone propionate's use in specific populations has not been well studied. Fluticasone propionate is not carcinogenic, mutagenic, or clastogenic, nor did it affect fertility in animal studies. Subcutaneous fluticasone propionate has been shown to produce teratogenic effects in rats though oral administration does not. Generally, there are no reported adverse effects with fluticasone in pregnancy. Fluticasone propionate in human milk may cause growth suppression, effects on endogenous corticosteroid production, or other effects. Pediatric patients treated with fluticasone propionate ointment experienced adrenal suppression. Geriatric patients treated with fluticasone propionate did not show any difference in safety or efficacy compared to other patient groups, though older patients may be more sensitive to adverse effects. There is no difference in the clearance of fluticasone propionate across genders or race. Patients with hepatic impairment should be closely monitored due to the elimination mechanism.

Volume of Distribution

The volume of distribution of intravenous fluticasone propionate is 4.2L/kg. A study of 24 healthy Caucasian males showed a volume of distribution at steady state of 577L following intravenous administration.

Following IV administration to healthy subjects, the mean volume of distribution at steady state was 661 L.

Elimination Route

Intranasal bioavailability of fluticasone propionate is 10. Intranasal exposure results in the majority of the dose being swallowed. Topical absorption of fluticasone propionate is very low but can change depending on a number of factors including integrity of the skin and the presence of inflammation or disease. A study of 24 healthy Caucasian males showed an inhaled bioavailability of 9.0%.

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.

Half Life

7.8 hours for intravenous fluticasone propionate. A study of 24 healthy Caucasian males shows a half life of 14.0 hours following intravenous administration and 10.8 hours following inhalation.

21.3 hr

Clearance

1093mL/min for fluticasone propionate. A study of 24 healthy Caucasian males showed a clearance of 63.9L/h following intravenous administration.

Elimination Route

Fluticasone propionate is mainly eliminated in the feces with 10,5.

Following oral administration, vilanterol is eliminated mainly by metabolism by CYP3A4 followed by excretion of metabolites in urine (70%) and feces (30%).
