OBJECTIVE To investigate the effects of hormone therapy on brain structure in a randomized, double-blinded, placebo-controlled trial in recently postmenopausal women. METHODS Participants (aged 42-56 years, within 5-36 months past menopause) in the Kronos Early Estrogen Prevention Study were randomized to (1) 0.45 mg/d oral conjugated equine estrogens (CEE), (2) 50 μg/d transdermal 17β-estrad...
The individual effects of estrogen and progesterone on baroreflex function remain poorly understood. We sought to determine how estradiol (E2) and progesterone (P4) independently alter the carotid-cardiac and carotid-vasomotor baroreflexes in young women by using a hormone suppression and exogenous add-back design. Thirty-two young women were divided into two groups and studied under three cond...
The aim of the present study was to develop and investigate the feasibility of delivering Nebivolol as a transdermal patch by iontophoresis. The passive and electrically assisted transdermal delivery of Nebivolol hydrochloride by iontophoresis will improve the therapeutic efficacy and overcome the difficulties raised in oral drug delivery. Because of its extensive hepatic metabolism and low dos...
Transdermal administration of drugs is generally limited by the barrier function of the skin. Colloidal systems are one of the most contentious methods for transdermal delivery of active substances across the skin. The colloidal systems helps in overcoming the shortcomings associated with transdermal drug delivery systems and provide sustained and controlled release of drugs. This review presen...
BACKGROUND Serotonin (5-hydroxytryptamine, 5-HT) is modulated by sex steroid hormones and affects vascular function and mood. In the Kronos Early Estrogen Prevention Cognitive and Affective Ancillary Study (KEEPS-Cog), women randomized to oral conjugated equine estrogens (oCEE) showed greater benefit on affective mood states than women randomized to transdermal 17β-estradiol (tE2) or placebo (P...
In women, progesterone suppresses luteinizing hormone (LH) (gonadotropin-releasing hormone) pulse frequency, but how rapidly this occurs is unknown. In estradiol-pretreated women in the late follicular phase, progesterone administration at 1800 did not slow sleep-associated LH pulse frequency. However, mechanisms controlling LH pulse frequency may differ according to sleep status; and we thus h...
