Compound Paracetamol and Amantadine Hydrochloride Capsules: Mechanism of Action and Therapeutic Effects

Compound Paracetamol and Amantadine Hydrochloride Capsules are light-yellow small pellets. They contain paracetamol (acetaminophen), caffeine, artificial bezoar, and chlorpheniramine maleate. These capsules are primarily used to relieve symptoms associated with the common cold and influenza—including fever, headache, nasal congestion, and sore throat—and may also be used for both prevention and treatment of influenza. So, what are the pharmacological actions and therapeutic effects of Compound Paracetamol and Amantadine Hydrochloride Capsules? The following section provides a detailed explanation.

Pharmacological Actions and Therapeutic Effects of Compound Paracetamol and Amantadine Hydrochloride Capsules

1. Antipyretic and Analgesic Effects

Compound Paracetamol and Amantadine Hydrochloride Capsules exert antipyretic and analgesic effects. This is attributable to their active ingredients—paracetamol and caffeine. Paracetamol inhibits prostaglandin synthesis, thereby producing antipyretic and analgesic effects. It is mainly used to alleviate fever, headache, pharyngeal pain, generalized myalgia, and rhinorrhea caused by the common cold. Caffeine, a central nervous system stimulant, potentiates the antipyretic and analgesic effects of paracetamol while counteracting central nervous system depression (e.g., drowsiness and dizziness) induced by other components, thus helping to reduce fatigue.

2. Antibacterial Activity

Compound Paracetamol and Amantadine Hydrochloride Capsules possess antibacterial activity. This stems from the presence of artificial bezoar and chlorpheniramine maleate in the formulation. Chlorpheniramine maleate is an antihistamine that relieves nasal congestion and sneezing but may cause drowsiness as a side effect. Artificial bezoar exhibits antibacterial and antiviral properties. Consequently, the compound formulation demonstrates certain antibacterial effects.
