FLUTICASONE FUROATE AND VILANTEROL (FF/VI) VERSUS FLUTICASONE PROPRIONATE AND FORMOTEROL (FP/FM) AS MAINTENANCE THERAPY IN STABLE ASTHMATIC PATIENTS- A COMPARATIVE STUDY

Background: Fluticasone furoate (FF) is a novel long-acting inhaled corticosteroid (ICS). Vilanterol (VI) is a long‐acting beta2‐agonist (LABA) that binds to the beta2‐adrenoceptor on the airway smooth muscle, producing bronchodilation. The corticosteroid fluticasone propionate (FP)and the long-acting β₂-adrenoceptor agonist (LABA) formoterol fumarate (FM) have been combined in a single, pressurized, metered-dose, aerosol inhaler for the maintenance treatment of patients aged ≥12 years with persistent asthma.This study evaluated the efficacy and safety of Fluticasone furoate 100 mcgandVilanterol 6 mcg versus Fluticasone proprionate 250 mcg and Formoterol 25 mcg for 12 weeks in patients with persistent asthma as maintenance therapy. Methods and Materials: A hospital based comparative study was conducted among stable asthmatic patients attended to Santhiram Medical College and General Hospital, Nandyal during January 2024 to June 2024(6months) by using convenient sampling method with sample size 60. Study tool was pre-designed, pre-tested, asthma control questionnaire5 (ACQ5),asthma control test (ACT) and Ask 12 adherence barrier survey. Results: Among 60 patients, 30 patients (Group1) were given Fluticasone furoate and Vilanterol and another 30 patients (Group 2) were given Fluticasone proprionate and Formoterol. All the patients (both the treatment groups) completed the 12 weeks treatment period. Improvements from baseline in 0- to 24-h wmFEV1 were observed with both FF/VI (376 mL) and FP/FM (353 mL) the adjusted mean treatment difference was not statistically significant. There were no differences between 0- to 4-h serial wmFEV1, asthma control test, ACQ5 and Ask 12 adherence barrier survey. There was no difference in reported exacerbations between treatments. Adverse events reported in the present study were not significant. Both treatments were well tolerated. Conclusion: The present study shows that the efficacy of once daily Fluticasone furoate and Vilanterol was not inferior as compared to the efficacy of twice daily Fluticasone proprionate and Formoterol as maintenance therapy in stable asthmatic patients. Howevertreatment with once daily FF/VI has the advantage of forgetfulness and inconvenience of inhalation.Henceonce daily FF/VI can be also useful for stable asthmatic patients as maintenance therapy as FF/VI DPI treatment.
