Effects and Efficacy of Compound Paracetamol and Amantadine Hydrochloride Tablets

Compound Paracetamol and Amantadine Tablets are a medication with antipyretic (fever-reducing) and analgesic (pain-relieving) properties. They are indicated for the treatment of common cold symptoms such as nasal congestion, sore throat, headache, and fever, and also possess both preventive and therapeutic effects against influenza. The active ingredients include paracetamol (acetaminophen), amantadine hydrochloride, chlorpheniramine maleate, artificial bezoar, and caffeine; excipients include starch, sugar powder, and magnesium stearate. So, what are the pharmacological actions and clinical benefits of Compound Paracetamol and Amantadine Tablets? Below, we address this question.

Pharmacological Actions and Clinical Benefits of Compound Paracetamol and Amantadine Tablets

1. Antipyretic and Analgesic Effects

The mechanism of action of Compound Paracetamol and Amantadine Tablets involves inhibition of prostaglandin synthesis and release in the hypothalamic thermoregulatory center, leading to peripheral vasodilation. Key active ingredients include paracetamol, amantadine hydrochloride, caffeine, and chlorpheniramine maleate. Among these, paracetamol provides antipyretic and analgesic effects; amantadine hydrochloride exhibits anti-influenza activity; and the other components collectively help alleviate various discomforts associated with the common cold.

2. Antiallergic Effects

Compound Paracetamol and Amantadine Tablets are primarily used to relieve symptoms of bacterial or viral upper respiratory tract infections—including fever, headache, sneezing, rhinorrhea (runny nose), cough, sputum production, and pharyngeal pain and swelling. The amantadine component demonstrates specific antiviral activity against influenza A virus, while the remaining ingredients possess anti-inflammatory and antiallergic properties.

Additional Information: Adverse Effects of Compound Paracetamol and Amantadine Tablets

1. Rare adverse reactions include rash, nausea, vomiting, diaphoresis (excessive sweating), abdominal pain, anorexia, and pallor. Some patients may experience drowsiness or mild dizziness upon initial administration; these symptoms typically resolve upon discontinuation of the drug. Additionally, methemoglobinemia—manifesting as cyanosis—may occur. Prolonged or high-dose use may impair hepatic and renal function.

2. In some cases, hallucinations and mental disturbances may arise, accompanied by slurred speech, involuntary eye movements, central nervous system overstimulation, or signs of toxicity. In elderly patients, adverse effects may include urinary retention, syncope, orthostatic hypotension, and leukopenia.

3. Persistent adverse reactions may include impaired concentration, dizziness, irritability, anorexia, and nervousness. Less common manifestations include headache, blurred vision, dryness of mouth, nose, and throat, and constipation.

The above outlines the pharmacological actions and clinical benefits of Compound Paracetamol and Amantadine Tablets. We hope this information is helpful to you.
