As a compound preparation, its main function is analgesic and anti-inflammatory, and its indications are used for cold, fever, headache, neuralgia and rheumatic pain. Its main ingredients are aminopyrine, acetaminophen, caffeine and chlorpheniramine maleate. Aminopyralid acts as analgesic and anti-inflammatory by inhibiting the synthesis of prostaglandins, and acetaminophen has antipyretic and analgesic effects. Caffeine enhances the headache-relieving effects of the first two drugs. Chlorpheniramine maleate is anti-allergic and relieves respiratory nasal congestion and runny nose. Adverse reactions such as vomiting, rash, fever, profuse sweating and stomatitis may occur after use of the drug, which can usually be relieved after stopping the drug. Patients who are breastfeeding should use the drug with caution; prolonged use of this drug can cause dependence and tolerance. The use of this drug is prohibited for those who are allergic to aminopyralid, caffeine or chlorpheniramine maleate, patients with gastric ulcers, newborns or premature infants. The specific dosage and usage of the above medicines should follow the doctor’s instructions and should not be used on its own to avoid adverse reactions.
