Quality changes of sodium valproate tablets stored in the moisture-suppression bag. The tablets packed in cellophane polyethylene laminating paper were stored in the moisture-suppression bag and plastic bags with 15 or 30 g desiccating agents. The samples were stored at 75% RH and 35 °C (A–C) or 25 °C (D, E). Weight change (n = 5) (A, D), hardness (n = 5) (B, E), and appearance (C) are shown. : moisture-suppression bag, : plastic bags with 15 g desiccating agent, ×: plastic bags with 30 g desiccating agent. ^aP < 0.001, ^a′P < 0.01, ^a″P < 0.05 (vs. day 0), ^bP < 0.001, ^b″P < 0.05 (vs. plastic bags with 15 g desiccating agent), ^cP < 0.001, ^c′P < 0.01 (vs. plastic bags with 30 g desiccating agent) (Tukey–Kramer test)
