Pharmacology

Cetirizine hydrochloride is a potent H1 receptor antagonist that effectively blocks the effects of histamine. Unlike other antihistamines, it does not have significant anticholinergic or antiserotonergic effects. At therapeutic doses, cetirizine has minimal sedative effects and does not cause behavior changes.

When a dose of 10 mg cetirizine is administered, it reaches peak plasma concentration within approximately 1 hour, with levels of 257 mcg/L in adults and 980 mcg/L in children. Food intake does not affect the extent of absorption, although it may slightly delay the absorption process. The peak blood concentration of approximately 0.3 μg/ml is reached 30 to 60 minutes after taking a 10 mg dose of cetirizine.

The plasma half-life of cetirizine is around 11 hours, meaning it takes approximately 11 hours for half of the drug to be eliminated from the bloodstream. The absorption rate of cetirizine from one individual to another is consistent and predictable. Renal clearance, which represents the rate at which the drug is removed from the body by the kidneys, is approximately 30 ml/min. The excretion half-life, which indicates the time it takes for half of the drug to be eliminated from the body, is approximately 9 hours.

It's important to note that the pharmacokinetics of cetirizine can vary slightly among individuals, and the information provided here represents general characteristics of the drug's absorption, distribution, metabolism, and elimination. Specific dosing instructions and considerations should be followed as directed by a healthcare professional.

Pregnancy & Lactation

According to the United States FDA classification, cetirizine hydrochloride is categorized as pregnancy classification B. This classification indicates that there are no adequate and well-controlled studies on pregnant women. While animal studies have not shown any adverse effects on fetal development, it is important to note that animal studies do not always accurately predict the human response.

Therefore, the use of cetirizine hydrochloride during pregnancy should only be considered if the potential benefits outweigh the potential risks and only when clearly necessary. It is advisable to consult with a healthcare professional before taking cetirizine or any medication during pregnancy.

Cetirizine hydrochloride has been shown to be excreted in human milk. Therefore, caution should be exercised when administering cetirizine to lactating women. It is recommended to consult with a healthcare professional before using cetirizine while breastfeeding to assess the potential risks and benefits for both the mother and the infant.

It is always important to discuss any concerns or questions regarding medication use during pregnancy or while breastfeeding with a healthcare professional who can provide personalized advice based on the individual's specific situation.
