🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionCetirizine is rapidly absorbed after oral administration, with peak plasma concentrations reached in about 1 hour. Pseudoephedrine is also well absorbed from the gastrointestinal tract, with peak levels occurring in 1 to 2 hours. Food may delay the absorption of cetirizine slightly but does not significantly affect the extent of absorption.

DistributionCetirizine is widely distributed throughout the body, with a volume of distribution of approximately 0.5 L/kg. It is about 93% bound to plasma proteins. Pseudoephedrine distributes into body tissues and crosses the blood-brain barrier to a limited extent.

Protein BindingCetirizine is approximately 93% bound to plasma proteins. Pseudoephedrine is not significantly protein-bound.

MetabolismCetirizine undergoes minimal hepatic metabolism; it is primarily excreted unchanged in the urine. Pseudoephedrine is partially metabolized in the liver by N-demethylation to inactive metabolites.

Half-LifeThe elimination half-life of cetirizine is approximately 8 to 10 hours in adults with normal renal function. The half-life of pseudoephedrine is approximately 5 to 8 hours, depending on urine pH.

ExcretionCetirizine is primarily excreted unchanged in the urine via glomerular filtration and active tubular secretion. Pseudoephedrine is excreted in the urine, with about 55% to 75% of a dose excreted unchanged; urinary excretion is increased by acidic urine.

BioavailabilityThe oral bioavailability of cetirizine is high, approximately 70% or more. Pseudoephedrine has a bioavailability of about 90%.

Onset of ActionCetirizine begins to relieve allergic symptoms within 1 hour of oral administration. Pseudoephedrine starts to decongest the nasal passages within 30 to 60 minutes.

Peak Plasma TimeCetirizine reaches peak plasma concentrations in about 1 hour. Pseudoephedrine reaches peak plasma levels in 1 to 2 hours.

Duration of ActionCetirizine provides relief for about 24 hours, allowing once-daily dosing. Pseudoephedrine's decongestant effect lasts for 4 to 6 hours, but in this combination, it may be formulated for longer action; however, the exact duration depends on the specific product formulation.

How It Works

This medicine combines two active ingredients with complementary actions. Cetirizine is a selective peripheral H1-receptor antagonist that prevents histamine from binding to H1 receptors on blood vessels and nerve endings, thereby reducing allergy symptoms such as sneezing, itching, and runny nose. Pseudoephedrine is a sympathomimetic amine that directly and indirectly stimulates alpha-adrenergic receptors, causing vasoconstriction in the nasal mucosa, which reduces swelling and congestion. The combination provides both antihistaminic and decongestant effects.

Mechanism Steps

1

Histamine H1 receptor blockade: Cetirizine binds to H1 receptors on effector cells, preventing histamine from triggering allergic symptoms such as sneezing, itching, and increased mucus production.

2

Alpha-adrenergic receptor stimulation: Pseudoephedrine stimulates alpha-adrenergic receptors on nasal blood vessels, causing them to constrict and reduce blood flow, which decreases swelling and congestion.

3

Combined symptomatic relief: The antihistamine and decongestant actions work together to alleviate both allergic and congestive symptoms of rhinitis and colds.

💡 How to Take intazin ld tablet

Strength: Each 5 mL of syrup typically contains cetirizine 5 mg and pseudoephedrine 30 mg, but the exact strength may vary. Refer to the product label.

1Shake the bottle well before each use.

2Use a calibrated measuring cup or spoon to measure the dose accurately.

3Take the syrup orally, with or without food.

4If it upsets your stomach, take it with a meal or snack.

5Do not exceed the recommended dose or frequency.

Dosage Information

Adult Dosage	The usual adult dose is 5 to 10 mL of the syrup taken orally every 4 to 6 hours as needed, not to exceed 4 doses in 24 hours. However, the exact dose depends on the strength of the formulation and the patient's condition. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric Dosage	Pediatric dosing is not established from available information. Consult a pediatrician.
Elderly Dosage	Elderly patients may be more sensitive to the effects of cetirizine and pseudoephedrine. Start with a lower dose and monitor for side effects such as drowsiness, confusion, and cardiovascular effects. Dose must be individualized by a qualified clinician.
Renal Impairment	In patients with renal impairment, the dose of cetirizine may need to be reduced. Pseudoephedrine should be used with caution. Consult a doctor for dose adjustment.
Hepatic Impairment	No specific dose adjustment is provided for hepatic impairment, but caution is advised in severe liver disease. Consult a doctor.
Maximum Daily Dose	The maximum daily dose should not exceed the equivalent of 40 mg of pseudoephedrine and 40 mg of cetirizine, but the exact limit depends on the formulation. Do not exceed the recommended dose.
