estrogen therapy<\/a>.<\/p>\nMechanism of Action<\/h2>\n
Letrozole works by inhibiting the enzyme aromatase, which converts androgens into estrogens in the body. By reducing estrogen levels, letrozole helps to decrease the growth of estrogen-dependent breast cancer cells.<\/p>\n
Dosage Information<\/h2>\n
The recommended dose of Femara is 2.5 mg once daily, taken without regard to meals. Treatment should continue until tumor progression is evident.<\/p>\n
Administration Guidelines<\/h2>\n
Femara should be taken at the same time each day to maintain an even level of the drug in the body. Swallow the tablet whole, with a sufficient amount of water. Do not crush or chew the tablet.<\/p>\n
Storage Conditions<\/h2>\n
Store Femara at room temperature, between 20\u00b0C to 25\u00b0C (68\u00b0F to 77\u00b0F), in a tightly closed container. Protect from light and moisture.<\/p>\n
Pharmacokinetics<\/h2>\n
Letrozole is absorbed quickly after oral administration, reaching peak plasma concentrations within 1 hour. The drug\u2019s half-life is approximately 48 hours, which supports once-daily dosing.<\/p>\n
Metabolism and Excretion<\/h2>\n
Femara is primarily metabolized in the liver by CYP3A4 and CYP2A6 enzymes. Less than 10% of the drug is excreted unchanged in the urine.<\/p>\n
Contraindications<\/h2>\n
Femara should not be used in premenopausal women. It is contraindicated in individuals with a known hypersensitivity to letrozole or any of its excipients.<\/p>\n
Drug Interactions<\/h2>\n
Concomitant use of drugs known to affect CYP450 enzymes may alter the metabolism of letrozole. Monitor for interactions with medications such as phenytoin, carbamazepine, and rifampin.<\/p>\n
Adverse Reactions<\/h2>\n
Common adverse reactions include hot flashes, arthralgia, and osteoporosis. Less common side effects may include elevated liver enzymes, hypercholesterolemia, and carpal tunnel syndrome.<\/p>\n
Monitoring Requirements<\/h2>\n
Regular monitoring of bone mineral density (BMD) is recommended for patients taking Femara long-term, due to the risk of osteoporosis. Additionally, liver function tests should be performed periodically.<\/p>\n
Special Populations<\/h2>\n
Renal impairment: No dosage adjustment is needed for patients with mild to moderate renal impairment. Use with caution in severe renal impairment.<\/p>\n
Hepatic Impairment<\/h2>\n
No initial dose adjustment is required for patients with mild to moderate hepatic impairment. Patients with severe hepatic dysfunction should be monitored closely.<\/p>\n
Use in Elderly<\/h2>\n
Femara has been shown to be safe and effective in both elderly and younger postmenopausal women. No dose adjustment is necessary for elderly patients.<\/p>\n
Pregnancy Category<\/h2>\n
Femara is classified as Pregnancy Category D. It is contraindicated in women who are or may become pregnant due to potential fetal harm.<\/p>\n
Breastfeeding Considerations<\/h2>\n
Breastfeeding is not recommended while taking Femara, as it is not known whether the drug is excreted in human milk. The potential risks to the infant should be considered.<\/p>\n
Patient Counseling Information<\/h2>\n
Patients should be informed about the importance of adherence to prescribed dosing schedules. Encourage reporting of any unusual symptoms or side effects to their healthcare provider.<\/p>\n
Clinical Studies<\/h2>\n
Clinical trials have demonstrated the efficacy of Femara in increasing overall survival and disease-free survival in postmenopausal women with hormone-responsive breast cancer.<\/p>\n
Cost and Availability<\/h2>\n
Femara is available by prescription and is often covered by insurance plans. Generic versions may also be available under the name letrozole.<\/p>\n
Brand vs. Generic<\/h2>\n
The efficacy, safety, and pharmacokinetic profiles of generic letrozole are equivalent to the brand-name version, Femara. The choice between them may depend on cost and patient preference.<\/p>\n","protected":false},"excerpt":{"rendered":"
Femara, which is also known by its generic name letrozole, contains the active ingredient letrozole. It is commonly used to treat breast cancer in postmenopausal women. Femara works by lowering estrogen levels in the body, which can slow or stop the growth of some types of breast cancer cells. It is often prescribed for women who have finished other treatments, like surgery or radiation therapy, to help prevent the cancer from coming back.<\/p>\n
Femara Price<\/h2>\n
The Femara price is approximately \u00a31.5 – \u00a32.59 per pills. It depends on the size of the pack and the amount of active ingredient (30 or 270 mg).<\/p>\n","protected":false},"featured_media":50,"comment_status":"open","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[16],"product_tag":[],"class_list":{"0":"post-20","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-womans-health","7":"pa_active-ingredient-letrozole","8":"desktop-align-left","9":"tablet-align-left","10":"mobile-align-left","12":"first","13":"instock","14":"shipping-taxable","15":"product-type-external"},"_links":{"self":[{"href":"https:\/\/bannviewmedicalpractice.co.uk\/pharmacy\/wp-json\/wp\/v2\/product\/20","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bannviewmedicalpractice.co.uk\/pharmacy\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/bannviewmedicalpractice.co.uk\/pharmacy\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/bannviewmedicalpractice.co.uk\/pharmacy\/wp-json\/wp\/v2\/comments?post=20"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bannviewmedicalpractice.co.uk\/pharmacy\/wp-json\/wp\/v2\/media\/50"}],"wp:attachment":[{"href":"https:\/\/bannviewmedicalpractice.co.uk\/pharmacy\/wp-json\/wp\/v2\/media?parent=20"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bannviewmedicalpractice.co.uk\/pharmacy\/wp-json\/wp\/v2\/product_brand?post=20"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bannviewmedicalpractice.co.uk\/pharmacy\/wp-json\/wp\/v2\/product_cat?post=20"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bannviewmedicalpractice.co.uk\/pharmacy\/wp-json\/wp\/v2\/product_tag?post=20"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
