ICH Q1A(R2) & Q1B Photostability

Stability Testing & Shelf-Life Studies Across ICH Climatic Zones

Stability studies evaluate how drug quality varies over time under the influence of environmental factors (temperature, humidity, and light). Satvam Research manages sample pull schedules, chamber mapping, and testing at predetermined intervals (0, 1, 2, 3, 6, 9, 12, 18, 24, and 36 months) with stability-indicating assay, related substances, dissolution, and microbial enumeration.
