      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Prevention, Randomization description: In this study, a simple randomization method using a table of random numbers is used. In this study, which includes 64 samples, the numbers 00 to 64 are assigned to the samples. Then we randomly select a table point in the row direction. We select numbers smaller than the size of the study population. The selected numbers are in fact the individual code of the community that is selected as the sample. We will continue this until the sample size is complete and reaches the number 64, Blinding description: Study participants are not aware of the contents of the glass and whether it was a medicine or a placebo. Before the clinical caregiver gives the medication and placebo to the participants, another person performs the steps of pouring the drug and the placebo into the glass, and in this way, the clinical caregiver is blinded. Also, the main researcher of the project has no information about contents of each glass and does not know anything about which group receive placebo and which group receive medicine.</study_design>
