Introduction to Estring
Estring is a vaginal ring marketed by Pfizer, designed to treat vaginal atrophy related to menopause. It continuously releases a low dose of estradiol, a female sex hormone, to alleviate symptoms such as painful intercourse and vaginal dryness.
Market Size and Growth
The market for estrogen replacement therapies, which includes Estring, is significant and growing. The global estrogen replacement therapy market is estimated to reach $13.2 billion by 2027, growing at a CAGR of 5.7% during the forecast period 2022-2027[2].
Price Trends and Affordability
Over the years, the prices of Estring and other estradiol products have increased substantially. For instance, the price of Estring rose from less than $300 at the start of 2014 to more than $500 by 2018. Similarly, Allergan's Estrace Cream saw its price increase from about $200 to $330 per tube over the same period[1].
Despite these price hikes, Estring remains covered by most insurance plans for the majority of patients. However, patients often face higher out-of-pocket costs due to increased deductibles and copays. To mitigate these costs, some patients opt for purchasing estradiol products from overseas outlets, where they can be significantly cheaper[1].
Generic Competition
The introduction of generic versions of estradiol products has provided some relief in terms of pricing. For example, Amneal launched a generic to Novo Nordisk's Vagifem in 2016, and Teva launched another generic in 2017. Additionally, after Estrace Cream lost its patent protections in December 2017, generics from companies like Mylan and Teva entered the market, potentially driving prices down[1].
However, Estring itself does not have a generic version available, which maintains its market position but also keeps its prices higher compared to generic alternatives[1].
Sales Forecast
The sales forecast for Estring and similar products is influenced by several factors, including the growing awareness of menopausal symptoms and the need for hormone replacement therapies. Here are some key points:
-
Historical Sales: The postmenopausal vaginal atrophy market, where Estring is a key player, has experienced anemic growth in the past but is expected to undergo significant changes. The market has a large untreated population due to low diagnosis rates and safety concerns with existing therapies[4].

While Estring is not the dominant product in this market (Nuvaring holds that position), it remains a significant player[5].
-
Regional Insights: North America, particularly the U.S., accounts for the highest revenue share in the estrogen replacement therapy market. This region is expected to continue dominating the market due to high demand and advanced healthcare infrastructure[2].
