title: Clinical experience with transdermal estradiol in the treatment of the climacteric.
abstract: Results of clinical studies have revealed that the transdermal therapeutic system of estrogen administration (Estraderm, Ciba Pharmaceutical Co., Summit, New Jersey) is both effective and well tolerated. Relief of hot flushes and vaginal atrophy has been shown to equal oral administration of conjugated equine estrogens and early experience suggests that the bone sparing effect is maintained. The patch has no effect on certain liver proteins; safety variables have shown no adverse biochemical changes. Moderate bleeding has occurred in some patients with an intact uterus but can be controlled by the addition of a progestogen. The incidence of endometrial hyperplasia and breast tenderness has been relatively low, and minor side effects (such as fluid retention) have been limited. Several investigators have evaluated skin irritation resulting from the systems. Some erythema has been reported but serious ulcerations or sloughing did not occur. A survey of patient attitudes comparing oral administration and transdermal systems indicated a preference for the transdermal method.
