Formula Information

A small arrow pointing down

Estriol 3 mg Vaginal Suppositories are a specialized formulation designed to deliver a precise dose of the estrogen hormone estriol directly to the vaginal tissue. Estriol is a naturally occurring estrogen that is often prescribed for its beneficial effects in managing symptoms associated with menopause, such as vaginal atrophy, dryness, itching, and burning. These symptoms result from the thinning and inflammation of the vaginal walls due to the decline in estrogen levels. By delivering estriol locally, the suppositories help to restore the vaginal tissue, improve lubrication, and maintain a healthy vaginal environment.

The suppository is a solid dosage form that is inserted into the vagina, where it dissolves or melts at body temperature. This allows for the direct application of the medication to the affected area, providing targeted relief with minimal systemic absorption. This localized approach can lead to fewer systemic side effects compared to oral hormone replacement therapies. The use of estriol in this form is also beneficial for women who may not be candidates for systemic hormone therapy due to certain health risks or personal preferences.

Estriol suppositories may also be used as part of the management of urogenital symptoms such as urinary urgency, incontinence, or recurrent urinary tract infections, as estriol can help to improve the health of the urethral and bladder mucosa. It is important to note that while estriol suppositories can be very effective for these indications, they should be used under the guidance of a healthcare provider, as hormone replacement therapy can be contraindicated in certain conditions such as hormone-sensitive cancers or a history of thromboembolic events.

For patients and prescribers considering the use of Estriol 3 mg Vaginal Suppositories, it is essential to have a thorough understanding of the patient's medical history, current medications, and any potential risks associated with hormone therapy. Regular monitoring and follow-up appointments are recommended to assess the effectiveness of the treatment and to make any necessary adjustments. If you have any questions or require further information about this formulation, please do not hesitate to reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is dedicated to providing personalized care and support to ensure the best possible outcomes for our patients.

Drug Interactions

A small arrow pointing down

Estriol is a form of estrogen, a female hormone that regulates various processes in the body. Estriol 3 mg vaginal suppositories are designed to be inserted into the vagina where they dissolve and release the hormone directly at the site of action. This local administration can help minimize systemic absorption and reduce the potential for systemic side effects. Estriol is commonly used to treat symptoms of menopause such as vaginal dryness, itching, and burning. It can also be used in the management of atrophic vaginitis and kraurosis vulvae.

When considering the use of estriol vaginal suppositories, it is important to be aware of potential drug interactions. Estriol can interact with other medications, both prescription and over-the-counter, as well as herbal supplements. For example, the concurrent use of estriol with other hormonal therapies, such as progestins or other estrogens, may alter the effects of either medication and increase the risk of side effects such as endometrial hyperplasia or cancer. Patients should inform their healthcare provider of all medications they are taking, including hormone replacement therapy or birth control pills.

Enzyme inducers, such as certain anticonvulsants (like phenytoin or carbamazepine) and some antibiotics (such as rifampicin), may decrease the effectiveness of estriol by increasing its metabolism. Conversely, enzyme inhibitors like ketoconazole or itraconazole may increase estriol levels, potentially leading to an increased risk of side effects. Patients should be monitored for changes in efficacy or side effects if these medications are used concurrently with estriol suppositories.

Estriol may also interfere with the metabolism of other drugs by affecting hepatic enzymes such as cytochrome P450. This can lead to either an increase or decrease in the plasma concentrations of drugs metabolized by these enzymes, which could necessitate dosage adjustments of the affected medications. Additionally, estriol can influence the coagulation cascade, and therefore, caution is advised when used in conjunction with anticoagulant medications like warfarin, as there may be an increased risk of bleeding.

Patients with a history of estrogen-dependent tumors should use estriol with caution, as it may exacerbate these conditions. Similarly, individuals with liver dysfunction, thromboembolic disorders, or a history of hormone-sensitive cancers should consult their healthcare provider before using estriol suppositories.

It is also important to note that smoking can increase the risk of serious cardiovascular side effects from estrogen therapy, and this risk increases with age and the number of cigarettes smoked. Therefore, patients are advised to avoid smoking while using estriol vaginal suppositories.

Lastly, while estriol is primarily used for local treatment, any systemic absorption that does occur could potentially interact with other systemic medications. Therefore, it is crucial for patients to maintain open communication with their healthcare providers about all medications and supplements they are taking.

If you have any questions or concerns regarding the use of Estriol 3 mg Vaginal Suppositories or potential drug interactions, please reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is here to provide you with the information and support you need to safely manage your health.

How Does it Work

A small arrow pointing down

The Estriol 3 mg Vaginal Suppository is a solid dosage form designed to be inserted into the vagina, where it dissolves or melts at body temperature. Upon insertion, the suppository base, typically made from substances like cocoa butter or a synthetic analogue, begins to melt due to the warmth of the body, allowing the active pharmaceutical ingredient, estriol, to be released. Estriol is a naturally occurring estrogen, one of the primary female sex hormones, which plays a crucial role in maintaining the health and function of the vaginal tissue and urogenital tract.

Estriol works primarily through its local estrogenic effects. When the suppository is inserted into the vagina, estriol is released and absorbed through the vaginal mucosa. It then binds to estrogen receptors in the vaginal tissue, which stimulates the normal growth and development of the epithelium and increases the thickness of the vaginal mucosa. This action helps to restore the natural acidity of the vagina, which is important for its protective barrier function and for maintaining a healthy balance of flora. Additionally, estriol helps to increase blood flow and natural lubrication, which can alleviate symptoms of vaginal atrophy such as dryness, itching, burning, and discomfort during intercourse.

Estriol vaginal suppositories are commonly used in the treatment of atrophic vaginitis, which is a condition often associated with menopause due to the decrease in estrogen levels. By providing a local dose of estrogen directly to the affected area, estriol suppositories can effectively treat the symptoms of vaginal atrophy without significantly increasing estrogen levels throughout the rest of the body. This localized approach minimizes systemic absorption and reduces the risk of adverse effects that can be associated with systemic hormone replacement therapy.

For patients and prescribers considering the use of Estriol 3 mg Vaginal Suppositories, it is important to understand that while this treatment is effective for many women, it may not be suitable for everyone. Women with a history of hormone-sensitive cancers, unexplained vaginal bleeding, or those who are pregnant or breastfeeding should discuss the use of estriol with their healthcare provider. As with any medication, adherence to the prescribed regimen and proper insertion technique are key to achieving the best therapeutic outcomes. If you have any questions or concerns about the use of Estriol 3 mg Vaginal Suppositories, please reach out to us at Bayview Pharmacy for further information and personalized advice.

Other Uses

A small arrow pointing down

Estriol 3 mg vaginal suppositories are primarily prescribed for their local effect in managing symptoms associated with menopause such as atrophic vaginitis, which includes vaginal dryness, itching, and irritation. However, aside from their common indication, estriol suppositories may also have off-label uses. For example, they might be considered for the non-invasive management of certain urogenital symptoms such as urinary urgency, recurrent urinary tract infections (UTIs), and supportive treatment in urogenital surgeries. Estriol, as a weaker estrogen, is thought to have a favorable safety profile and might be preferred in patients where stronger estrogens are contraindicated.

Additionally, estriol can have a role in dermatological applications. Some evidence suggests topical estriol can promote skin elasticity and skin hydration; however, when used as a vaginal suppository, the systemic absorption of estriol may be minimal. Thus, its dermatological benefits through this route of administration may be limited or indirect. Patients and prescribers considering estriol suppositories for non-traditional uses should consult clinical guidance and consider the evidence supporting these applications. It's also important to weigh the benefits against potential risks, especially in patients with a history of hormone-sensitive conditions.

Furthermore, there is ongoing research into the neuroprotective effects of estrogens including estriol. Some preliminary studies indicate potential uses in the management of multiple sclerosis and other neurodegenerative disorders, although these findings are not yet definitive and estriol in vaginal suppository form for such uses is not standard treatment. Prescribers should exercise their clinical judgment and refer to the latest research and guidelines when considering estriol for such off-label applications.

It's critical to emphasize that any alternative or off-label use of estriol 3 mg vaginal suppositories should be initiated under close medical supervision, with adequate patient counseling regarding the potential benefits and risks. Such uses should be based on a solid rationale, supported by clinical evidence, and in alignment with current medical standards.
