Snorelip is a spray that costs about$20 for a box of topical nasal spray, and the main ingredient is Neostigmine Methylsulfate. Snorelip is mainly used for people with breathing disorders, which can unblock the nasal passage and keep the airway open. It is especially suitable for snorers with various causes, who have narrower nasal passages than normal people, especially after sleeping at night, causing local narrowing of the airway, and when the airflow passes through the narrowed area, it will produce eddy currents and cause vibration and snoring. In the most severe cases, the airway may be completely blocked and gas cannot enter and exit the lungs normally, which may lead to apnea and carbon dioxide retention in the body, causing hypoxemia and hypercarbia. This medication can relieve snoring by spraying the nasal passages.
