Estradiol 0.25mg, 0.5mg, 1mg; per packet; topical gel.
Indication:
Moderate to severe vasomotor menopausal symptoms.
Pharmacology:
The addition of exogenous estrogens helps to alleviate the vasomotor symptoms associated with declining estrogen levels.
Divigel (estradiol 0.1%) is a clear, colorless, alcohol-based gel that is designed to deliver sustained circulating concentrations of estradiol when applied once daily to the skin.
Clinical trials:
The efficacy of this product in treating vasomotor symptoms in post-menopausal women was evaluated in a
12-week, double-blind, placebo-controlled trial involving 495 patients. Divigel 0.25g, 0.5g, or 1g (corresponding to 0.25mg, 0.5mg, and 1mg estradiol), applied once daily to the thigh, was compared to placebo. At week 4, Divigel at doses of 0.5g and 1g/day resulted in significant reductions in the median daily frequency and the median daily severity of moderate to severe hot flushes compared to placebo; at week 7, treatment with Divigel 0.25g/day also reached statistical significance in improvements in these measurements. The statistically significant reductions in median daily frequency and severity of hot flashes were continued through week 12 for all three Divigel doses compared to placebo.
Adults:
Apply entire contents of 1 packet once daily to 5” x 7” area of dry intact skin on upper thigh; alternate right and left thigh for daily application. Initially 0.25g (corresponding to 0.25mg estradiol)/day; individualize. Allow gel to dry before dressing; do not wash area for at least 1 hr after application; wash hands after use.
