Objectives: Ethionamide being thermolabile in nature, effect of temperature on the drug and its stability in liquid and solid media during susceptibility testing procedures was assessed to understand the inconsistency in DST formats. Materials and Methods: Working solution of ethionamide and Lowenstein- Jensen (LJ) media incorporated with ethionamide were preincubated at 4oC and 37oC prior to DST methods was incubated till 4 weeks at different temperatures and utilized for DST in MGIT 960. Results: Degradation of ethionamide working solution was observed at 37oC after 3 weeks of incubation. Ethionamide incorporated LJ media can be stored without compromise on susceptibility up to 5 weeks. But, a week of prior incubation at 37oC has deleterious effect on the DST profile. Ethionamide was found to degrade at 37oC after different time points when stored as solution or as LJ media. Conclusion: Use of DST formats that provide results within 2 weeks can be recommended for ethionamide susceptibility testing.

Amaç: Ethionamide ısıya duyarlı yapısı nedeniyle, ilaç duyarlılık testinde (DST) ısının etkisini ve sıvı veya katı ortamdaki dayanıklılık durumunun araştırılması amaçlanmıştır. Yöntemler: Ethionamide çalışma solüsyonu ve Lowenstein-Jensen (LJ) besiyeri hazırlanarak 4°C ve 37°C bekletildi ve ardından DST yöntemiyle 4 haftaya kadar MGIT 960 besiyeri ile test edildi. Bulgular: Ethionamide çalışma solusyonunda 37°C’de 3 haftalık inkübasyonun ardından bozunma olduğu gözlenmiştir. Ethionamide LJ ortamında beş haftaya kadar etkinliğinde bozulma olmadan saklanabilir. Fakat 37°C de bir hafta daha bekletilmesi ilaç duyarlılık profiline zararlı etkili olabilir. Ethionamide 37°C bekletilmesiyle farklı zaman aralıklarında sıvı ya da LJ ortamında bekletilmesiyle etkinliğinde değişmeler olduğu saptandı. Sonuç: DST ortamında ethionamide için iki haftaya kadar olan testlerin değerlendirilmesi önerilir
