β-estradiol CAS 50-28-2

1). Hormone replacement therapy (HRT):

Treats menopausal symptoms (e.g., hot flashes, vaginal dryness, mood changes) and reduces the risk of osteoporosis in postmenopausal women.

Used to manage estrogen deficiency due to ovarian failure, surgical menopause, or genetic conditions (e.g., Turner syndrome).

2). Contraception:

Part of combined oral contraceptives to prevent pregnancy by inhibiting ovulation (often in combination with progestins).

3). Gender-affirming therapy:

Administered in transgender women to induce feminizing hormonal changes (e.g., breast development, fat redistribution) as part of gender-affirming care.

4). Hormonal regulation:

Treats irregular menstrual cycles, primary ovarian insufficiency, or atrophic vaginitis by restoring estrogen levels.

5). Cancer therapy (off-label):

Used palliatively in hormone-responsive cancers (e.g., breast cancer in postmenopausal women, prostate cancer) to modulate estrogen receptor activity.

6). Topical and transdermal applications:

Applied via creams, patches, or gels to target local estrogen deficiency (e.g., vaginal atrophy) with systemic effects minimized.

1). Temperature: Store at room temperature (20–25°C, 68–77°F), with short-term storage acceptable between 15–30°C (59–86°F).

2). Light and moisture: Keep in a tightly sealed, light-resistant container (e.g., amber glass vial or opaque package) in a dry place, away from direct sunlight and humidity.

3). Form-specific considerations:

For oral tablets/capsules: Protect from moisture; do not store in bathrooms or humid environments.

For injectable solutions or topical products: Follow manufacturer guidelines (e.g., some transdermal patches may require storage below 25°C).

4). Avoid: Freezing (unless specified), excessive heat, or prolonged exposure to light.

5). Safety: Keep out of reach of children and pets; discard unused portions after the expiration date.

1). Shelf life: Typically 2–3 years when stored under recommended conditions (always check the expiration date on the packaging).

2). Degradation risks:

Light, heat, and humidity can accelerate decomposition, reducing efficacy and potentially forming harmful byproducts.

Oxidation or isomerization may occur with improper storage, altering the chemical structure of β-estradiol.

3). Discard if:

The medication shows signs of discoloration (e.g., yellowing beyond the natural color), precipitation (in liquids), or an unusual odor.

The packaging is damaged, or the expiration date has passed.
