It has been said that nearly 30% of the patients with Alzheimer’ disease (AD) manifest loss of appetite, which might increase cognitive impairments and the incidence of neuropsychiatric symptoms, and malnutrition. As a result, a vicious cycle decreases functionality and quality of life in patients with AD. Cholinesterase inhibitors (ChEIs) is the first-line drugs in the treatment of AD. On the one hand, appetite or weight loss can be seen due to gastrointestinal side effects in the treatment of ChEIs. On the other hand, there are some reports in clinical-settings that patients with AD treated with rivastigmine transdermal patch showed the improvement of appetite loss.
To evaluate the efficacy of rivastigmine transdermal patch in AD patients with poor appetite.
In this 16-weeks, multicenter prospective study, patients with mild to moderate AD, who manifest loss of appetite and began to receive rivastigmine transdermal patch therapy, were enrolled. The amount of food, total time-eating, body weight, Mini Mental State Examination (MMSE) and Neuropsychiatric Inventory (NPI) were evaluated.
The amount of food eaten by treated patients significantly increased 10.5% at 8 weeks after the initiation of rivastigmine transdermal patch therapy.
This preliminary results might show favourable effects of rivastigmine transdermal patch therapy on AD patients with loss of appetite.
