Anastrozole is the generic name for Arimidex.
When is Anastrozole available generically?
Anastrozole became available as a generic medication in the United States in 2008 [1]. This followed the expiry of patents held by AstraZeneca, the original manufacturer of Arimidex [2].
What is Anastrozole used for?
Anastrozole is a type of drug known as an aromatase inhibitor. It is primarily used to treat hormone receptor-positive breast cancer in postmenopausal women [3]. It works by reducing the amount of estrogen the body produces, which can slow or stop the growth of breast cancer cells that rely on estrogen to grow [4]. Anastrozole is also sometimes used to treat breast cancer in premenopausal women when combined with other therapies, and in certain cases for fertility treatments [5].
What are the risks associated with Anastrozole?
Like all medications, anastrozole can cause side effects. Common side effects include hot flashes, joint pain, and fatigue [6]. More serious potential side effects can include bone thinning (osteoporosis), increased risk of fractures, and cardiovascular issues [7]. Patients are encouraged to discuss any concerns about side effects with their healthcare provider.
How does Anastrozole compare to other breast cancer treatments?
Anastrozole belongs to a class of drugs called aromatase inhibitors, which include other medications like letrozole and exemestane [8]. These drugs are often compared in clinical studies for their effectiveness and side effect profiles in treating breast cancer [9]. The choice of which aromatase inhibitor to use can depend on individual patient factors, including menopausal status, medical history, and tolerability of side effects [10].
Who makes generic Anastrozole?
Multiple pharmaceutical companies manufacture and distribute generic versions of anastrozole. These include companies like Teva Pharmaceuticals, Mylan, and Accord Healthcare, among others [11]. Availability and specific manufacturers may vary by region and pharmacy.
