A reduction in estrogen levels in the perimenopausal and postmenopausal periods causes various symptoms in women, such as hot flushes, sweats, depression, anxiety, and insomnia. Chlorogenic acids (CGAs), which are phenolic compounds widely present in plants such as coffee beans, have various physiological functions. However, the effects of CGAs on menopausal symptoms are unknown. To examine the effects of CGAs on menopausal symptoms, especially hot flushes, a randomized, placebo-controlled, double-blind, parallel-group trial was conducted in healthy women. Eighty-two subjects were randomized and assigned to receive CGAs (270 mg) tablets or the placebo for 4 weeks. After 4 weeks of intake, the number of hot flushes, the severity of hot flushes during sleep, and the severity of daytime sweats decreased significantly in the CGA group compared to the placebo group. The modified Kupperman index for menopausal symptoms decreased significantly after 2 weeks in the CGA group compared to the placebo group. Adverse effects caused by CGAs were not observed. The results show that continuous intake of CGAs resulted in improvements in menopausal symptoms, especially hot flushes, in healthy women.

This 1 week study compared the efficacy of once daily administration of 10 mg loratadine with 120 mg terfenadine in out-patients with seasonal allergic rhinitis. It focussed on the efficacy of treatment at the end of the 24 h period following a daily dose. The study was designed as a double-blind, randomized, parallel-group trial, and 41 patients were enrolled and evaluated for efficacy. Patients took an initial dose at the study site and returned on days 2 and 8. At day 2 (24 h after the initial dose), according to the physician's evaluation 57% of loratadine-treated patients had a good or excellent response, compared to 50% of those given terfenadine. At day 8, 24 h after the final dose, 71% of the loratadine-treated patients and 35% of the terfenadine-treated patients had a good or excellent response ( P = 0.03). At days 2 and 8, reductions in mean symptom scores measured 22, 23 and 24 h after the initial and final doses showed an indication of being greater with loratadine than with terfenadine (non-significant due to small sample size). The incidence of sedation was similar in both groups. It is concluded that 10 mg loratadine, administered once daily, controls the symptoms of rhinitis more effectively than 120 mg terfenadine given once daily in the last few hours of the 24 h dosing period.
