🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary actions. Chlorpheniramine maleate is a first-generation antihistamine that competitively blocks histamine H1 receptors on effector cells, reducing the symptoms of allergic reactions such as sneezing, itching, and increased mucus secretion. Phenylephrine is a sympathomimetic amine that primarily stimulates alpha-1 adrenergic receptors on vascular smooth muscle in the nasal mucosa, causing vasoconstriction and reduced blood flow, which decreases swelling and congestion. The combination provides relief from both allergic and congestive symptoms of the upper respiratory tract.
Mechanism Steps
💡 How to Take lemol syrup
Strength: Each 5 mL of syrup contains chlorpheniramine maleate 2 mg and phenylephrine hydrochloride 5 mg (or as specified by the manufacturer).
Dosage Information
| Adult Dosage | The usual adult dose of this medicine is 10 mL (2 teaspoons) every 4 to 6 hours as needed, not to exceed 6 doses in 24 hours. However, the exact dose and frequency depend on the indication, severity of symptoms, and individual patient factors. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not self-medicate beyond the recommended duration without consulting a doctor. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children. |
| Elderly Dosage | Elderly patients (65 years and older) are more sensitive to the side effects of chlorpheniramine, such as drowsiness, confusion, and anticholinergic effects. Phenylephrine may increase blood pressure and cause cardiac effects. Use with caution and at the lowest effective dose. Dose must be individualized by a qualified clinician. |
| Renal Impairment | Dose adjustment may be necessary in patients with severe renal impairment. Chlorpheniramine and phenylephrine are excreted by the kidneys. Consult a doctor for appropriate dosing. |
| Hepatic Impairment | Dose adjustment may be necessary in patients with severe hepatic impairment. Both drugs are metabolized in the liver. Consult a doctor for appropriate dosing. |
| Maximum Daily Dose | The maximum recommended daily dose for adults is 60 mL (12 teaspoons) in 24 hours, not to exceed 6 doses. Do not exceed the prescribed dose. |
