The bazedoxifene concentration (Cr) (mg/mL) of the working standard solution was calculated as follows:

Cr (mg/mL) = (Wr)(S)(Vr2)/(Vrl)(Vr3)

where:

Wr = weight of the reference standard, mg

S = use-at value of the reference standard as free base, decimal

...

The samples were then analyzed by HPLC to give the following results:

Initial 44.79% (use at value);
1 month at room temperature: 43.14% (use at value);
3 month at room temperature: 44.44% (use at value).
