The Efficacy and Function of Compound Paracetamol and Amantadine Capsules

Compound Paracetamol and Amantadine Capsules are commonly used to treat cold symptoms. The main ingredients include paracetamol (acetaminophen), amantadine hydrochloride, and chlorpheniramine maleate. Its therapeutic effects mainly include antiviral, antiallergic, antitussive (cough-suppressing), nasal decongestant, antipyretic, and analgesic effects. If needed, it should be used under the guidance of a physician. Detailed explanations are as follows:

1. Antiviral

Amantadine hydrochloride serves as the antiviral component in this medication. It inhibits the replication of cold viruses and alleviates cold symptoms. Although the effectiveness of amantadine may decrease with viral mutations, it still has some inhibitory effect on certain viruses.

2. Antiallergic

Chlorpheniramine maleate exerts antiallergic effects and can help relieve allergic reactions that may accompany a cold, such as skin itching and urticaria (hives).

3. Antitussive

Dextromethorphan, contained in Compound Paracetamol and Amantadine Capsules, suppresses the cough reflex in the central nervous system, thereby exerting an antitussive effect. It helps alleviate cough symptoms caused by the common cold.

4. Antipyretic and Analgesic

Paracetamol in the formulation inhibits prostaglandin synthesis and reduces the excitability of the thermoregulatory center, thereby producing antipyretic and analgesic effects.

5. Nasal Decongestant

Chlorpheniramine maleate is an antihistamine that effectively alleviates cold-related symptoms such as sneezing, runny nose, and nasal congestion, thus improving respiratory airflow.

However, caution should be exercised regarding dosage, as long-term and excessive use may lead to adverse effects such as allergic reactions and liver or kidney damage. Patients with impaired liver or kidney function, a history of mental illness, epilepsy, as well as pregnant and lactating women should use this medication with caution.
