Abstract

Objectives: The focal intent of the current research work is to develop and validate a novel and reliable stability-indicating reverse-phase high performance liquid chromatographic method for the simultaneous estimation of a few anti-retrovirals, i.e., bictegravir, emtricitabine, and tenofovir alafenamide fumarate (AF). Materials and Methods: The novel method employs inertsil octyldecylsilyl C18 (4.6×250 mm, 5 mm) using 0.2% triethylamine buffer and methanol in a ratio of 40:60% (v/v) as the mobile phase to attain optimal elution. The detection wavelength was 260 nm with a 1.2 mL/min flow rate and a 20 μL injection volume. Results: The linearity ranges for bictegravir, emtricitabine and tenofovir AF were 25-125 μg/mL, 100-500 μg/mL, and 12.5-62.5 μg/mL, respectively. The retention times for bictegravir, emtricitabine, and tenofovir AF were found to be 5.998 min, 2.805 min, and 4.537, min respectively. The percent recoveries of bictegravir, emtricitabine, and tenofovir AF were within the range of 98-102% w/w. Conclusion: The novel method was successfully validated as per International Conference on Harmonization guidelines. In forced degradation studies, emtricitabine was found to be sensitive to thermal conditions; bictegravir and tenofovir AF, to oxidative conditions. The developed method is economical and reliable for routine analysis concerning all validated parameters.

Özet

Amaç: Mevcut araştırma çalışmasının odak amacı, birkaç anti-retroviralin [biktegravir, emtrisitabin ve tenofovir alafenamid fumarat (AF)] eş zamanlı tahmini için yeni ve güvenilir bir stabilite gösteren ters fazlı yüksek performanslı sıvı kromatografik yöntemi geliştirmek ve doğrulamaktır. Gereç ve Yöntemler: Yeni yöntem, optimal elüsyona ulaşmak için mobil faz olarak %0,2 trietilamin tamponu ve %40:60 (h/h) oranında metanol kullanan inertsil octyldesilsilil C18’i (4,6×250 mm, 5 mm) kullanmaktadır. Deteksiyon dalga boyu 260 nm, akış hızı 1,2 mL/dk ve enjeksiyon hacmi 20 µL idi. Bulgular: Biktegravir, emtrisitabin ve tenofovir AF’nin doğrusallık ranjı sırasıyla 25-125 μg/mL, 100-500 μg/mL ve 12.5-62.5 μg/mL idi. Biktegravir, emtrisitabin ve tenofovir AF’nin retansiyon zamanları sırasıyla 5,998 dk, 2,805 dk ve 4,537 idi. Biktegravir, emtrisitabin ve tenofovir AF’nin yüzde gerikazanımları %98-102 a/a aralığında idi. Sonuç: Yeni yöntem, Uluslararası Uyumlaştırma Konferansı yönergelerine göre başarıyla doğrulanmıştır. Zorla bozunma çalışmalarında, emtrisitabin termal koşullara biktegravir ve tenofovir AF ise, oksidatif koşullara duyarlı olduğu bulunmuştur. Geliştirilen yöntem, tüm valide edilmiş parametrelerle ilgili rutin analizler için ekonomik ve güvenilirdir.
