Abstract

Objectives: Forced degradation determines the intrinsic stability of a molecule by establishing degradation pathways in order to identify the likelydegradation products (DPs). The objective of the present research was to establish intrinsic stability and forced degradation profiling of olopatadinehydrochloride.Materials and Methods: The intrinsic stability of olopatadine hydrochloride was evaluated by RP-HPLC, where a mixture of 0.1% formic acid andorganic phase (methanol:acetonitrile; 50:50 % v/v) was used as mobile phase at 1.0 mL/min in gradient mode. Different stress conditions wereemployed to explore the intrinsic stability of olopatadine hydrochloride.Results: In acidic condition, five DPs, i.e. OLO1, OLO2, OLO3, OLO4, and OLO5, were observed. OLO5 was the major DP that increased with time andthe peak area of OLO was decreased. In addition to OLO3 and OLO5, two more DPs were observed in alkaline condition, i.e. OLO6 and OLO7. OLO5and OLO6 were two major DPs; OLO5 increased with time while OLO6 had a zigzag pattern of peak area with time. All DPs of neutral condition werealso found in acidic condition while OLO3 and OLO5 were common in all three types of hydrolytic degradation.Conclusion: Thus, OLO has similar pattern of degradation profiling in all hydrolytic conditions (acidic, alkaline, and neutral). No degradation wasfound in thermal, ultraviolet light, or oxidative conditions over 10 days. OLO-Imp was recognized as an analogue structure of OLO and proposed as11-[(3-dimethylamino)-propylidene]-6,11-dihydro-dibenz[b,e]oxepin-2-propanoic acid in standard drug. OLO1 was identified as (2-(4-(dimethylamino)butyl) phenyl)methanol, which may be formed by cleavage of the tricyclic ring in neutral condition.

Özet

Amaç: Zorlanmış bozunma, muhtemel bozunma ürünlerini (DP) tanımlamak için bozunma yolları oluşturarak bir molekülün gerçek stabilitesini belirler. Bu araştırmanın amacı, olopatadin hidrokloridin gerçek stabilitesini ve zorlanmış bozunma profilini oluşturmaktır. Gereç ve Yöntemler: Olopatadin hidrokloridin gerçek stabilitesi, %0,1 formik asit ve organik faz karışımı (metanol: asetonitril;% 50:50 h/h) mobil faz olarak 1,0 mL/dak’de gradyan modunda kullanımıyla RP-YBSK ile değerlendirilmiştir. Olopatadin hidrokloridin gerçek stabilitesini araştırmak için farklı stres koşulları kullanılmıştır. Bulgular: Asidik koşulda, beş DP, yani OLO1, OLO2, OLO3, OLO4 ve OLO5 gözlenmiştir. başlıca DP OLO5 idi, pik süresi artmış ve OLO’nun pik alanı azalmıştır. OLO3 ve OLO5’e ek olarak, alkali koşullarda, iki DP daha, OLO6 ve OLO7 gözlenmiştir. OLO5 ve OLO6 iki ana DP idi; OLO5 zamanlaartarken OLO6 zamanla zikzak bir tepe alanı düzenine sahipti. Nötral koşullardaki bütün DP’ler asidik koşullarda da bulunurken, OLO3 ve OLO5 üç hidrolitik bozunma tipinde de ortaktı. Sonuç: OLO, tüm hidrolitik koşullarda (asidik, alkali ve nötr) benzer bir bozulma profiline sahiptir. Termal, ultraviyole ışığı veya oksidatif koşullarda 10 gün boyunca hiçbir bozulma bulunamamıştır. OLO-Imp, OLO’nun analog bir yapısı olarak kabul edilmiş ve standart ilaçta 11-[(3-dimetilamino) -propiliden]-6,11-dihidro-dibenz [b, e] oksepin-2-propanoik asit olarak önerilmiştir. OLO1, trisiklik halkanın nötr koşulda bölünmesiyle oluşturulabilecek (2-[4-(dimetilamino) butil] fenil) metanol olarak tanımlanmıştır.
