Study design (Archer 2003)3
A 12-week, multicentre, double-blind, randomised, placebo-controlled study of the effects of Oestrogel in 221 postmenopausal women to assess the effects of a percutaneous 17B-estradiol gel on vasomotor symptoms (VMS) compared to placebo.
Inclusion criteria3
Participants were assigned to receive either 1.25g or 2.5g of percutaneous 17β-estradiol gel or placebo, applied once daily over a 12-week period to evaluate efficacy and tolerability.
Primary endpoint3
The mean change from baseline to Week 12 in the daily frequency of moderate-to-severe hot flushes.
Secondary endpoints3
Frequency and severity of all VMS and vaginal maturation index.


| Adverse event | Placebo (n=73) | 0.75mg Oestrogel (n=75) | 1.5mg Oestrogel (n=73) |

| Breast pain | 7 | 8 | 8 |
| Infection | 5 | 12 | 5 |
| Pain | 8 | 5 | 4 |

The most common adverse events were headache (18.1%), breast pain (10.4%), infection (10.0%), pain (7.7%), nausea (7.2%), rash (5.4%) and vaginitis (5.4%).3
