Participants were required to keep a voiding diary, recording the occurrence of each micturition. The average daily number of micturitions was calculated as the total number of micturitions that occurred over a week (4 to 10 days) during the Base Study, divided by the total number of days of voiding kept in the participant's diary. Baseline was defined as the average daily number of daily micturitions that occurred during the week of placebo run-in prior to Week 0 visit.
An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug, whether or not it is considered related to the study drug.

An adverse experience was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the sponsor's product, whether or not considered related to the use of the product. Any worsening of a preexisting condition which is temporally associated with the use of the sponsor's product is also an adverse experience. The percentage of participants with a clinical or laboratory adverse experience was recorded.
Semi-recumbent and standing systolic blood pressure was measured predose and at intervals up to 24 hours postdose on Day 1 and Day 7. The baseline value is the average of measurements taken in the hour before dosing. Participants were to rest quietly in a semi-recumbent position for at least 10 minutes before each semi-recumbent measurement.

MK-4618 is an investigational small molecule being developed for the treatment of hypertension, a cardiovascular condition. It is currently in Phase 1 clinical development and has not been approved by regulatory authorities. The drug is being studied for its potential to lower blood pressure in patients with hypertension.
MK-4618 is being developed by Merck & Company, Inc., a pharmaceutical company traded on the New York Stock Exchange under the ticker symbol MRK. The company is conducting clinical trials to evaluate the safety and efficacy of this investigational drug for the treatment of hypertension.
MK-4618 is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory agencies. The Phase 1 trial has been completed, and the drug is still in the early stages of clinical testing for hypertension.
MK-4618 has one completed Phase 1 clinical trial registered under NCT01337674, titled "Co-Administration of MK-4618 With Antihypertensive Agents (MK-4618-010)." This randomized, double-blind, controlled study enrolled 26 participants with hypertension and evaluated the co-administration of MK-4618 with other antihypertensive agents.
MK-4618 is the primary identifier for this investigational drug. No alternative names have been established for this compound in the available clinical trial data. It is being studied under this designation by Merck & Company, Inc. for the treatment of hypertension.
