Rizmoic is a prescription medication primarily used to treat chronic idiopathic constipation (CIC) in adults. It works by enhancing bowel movements and improving stool consistency, making it easier for patients to pass stools. Rizmoic operates by selectively stimulating the serotonin 5-HT4 receptors in the gastrointestinal tract, which enhances gastrointestinal motility and fluid secretion. This action helps to alleviate symptoms associated with CIC, such as infrequent bowel movements, hard stools, and straining during defecation. As with any medication, it is important for patients to follow their healthcare provider's instructions when taking Rizmoic to ensure its effectiveness and minimize potential side effects.
