Exogenous melatonin safe for treating nocturia in elderly women, study says

This double-blind, randomized, placebo-controlled experiment was carried out in a Thai university hospital. Sixty women with nocturia over the age of 55 were recruited prospectively and randomly assigned to treatment (melatonin 2 mg/day, n = 30) or control (placebo, n = 30) arms for two weeks. Nocturia episodes, Nocturia Quality of Life Questionnaire (N-QoL) scores, nocturia-related parameters, and adverse events were used as outcome variables.

The key findings of this study were as follows:

1. In terms of mean age, the control and treatment groups were comparable (65.9 + 7.5 vs. 68.5 + 6.3 years).

2. With a baseline median voiding frequency of 2.3 and 2.3 episodes/night, respectively, both groups reported comparable causes of nocturia.

3. The treatment group outperformed the placebo group in terms of median nocturia reduction [-1.0 vs. 0.0 episodes/night], increased median duration of first uninterrupted sleep [1.0 vs. 0.0 h], and improvement in N-QoL scoring, particularly in the sleep/energy subscale.

4. The number of adverse events was comparable between groups.

In conclusion, the findings of this clearly point out the effectiveness of melatonin in the treatment of Nocturia in elderly women.
