Berlex Inc has received US FDAapproval for Angeliq (0.5 mg drospirenoneand 1 mg estradiol) for thetreatment of moderate-to-severe vasomotormenopausal symptoms and moderate-to-severe symptoms of vaginal andvulvar atrophy related to menopause inwomen who have a uterus.1 Up to 85% ofmenopausal women experience symptomssuch as hot flashes, sweating,insomnia, and vaginal dryness or discomfort.Treatment with hormone therapy isa popular option, as estrogen replacementhas been shown to controlmenopausal symptoms and improvepatients' quality of life.2

Mechanism of Action

Estrogen supplementation during menopauseis believed to relieve menopausalsymptoms by replacing the estrogen thatthe body is no longer able to make. Theestradiol form is the primary intracellularhuman estrogen and is more potent thanthe estrone or estriol forms.1

In women with a uterus, the use ofprogestin in conjunction with estrogenhas been associated with a lower incidenceof endometrial hyperplasia. As aresult, hormone therapy in women whohave not had a hysterectomy usuallyincludes a progestin component to balanceestrogen's effects.1 In addition, theprogestin component of Angeliq,drospirenone, exerts an antialdosteroneeffect and is promoted to counteractestradiol's sodium-and water-retentioneffect.3

Clinical Trials

The efficacy of treatment with Angeliqwas evaluated in a bioequivalence studycomparing the combinationproduct Angeliqwith estradiol (Estrace)1 mg, an estradiol productalready available.The trial determinedthe estradiol componentof Angeliq to bebioequivelent to Estrace.

The safety of Angeliqon the endometriumwas evaluated in a 1-year clinical trial comparingestradiol alonewith estradiol with 1, 2,or 3 mg of drospirenone. At the study'send, no patients in the Angeliq groupwere found to have endometrial hyperplasia.1
