Actions and Spectrum
acrivastine is a second-generation H1 histamine receptor antagonist. It works by blocking the action of histamine, a natural substance in the body that is released during allergic reactions.
Histamine is responsible for the symptoms of allergic reactions, and by blocking histamine receptors, it helps alleviate these symptoms.
Frequency not defined
Dry mouth
Dizziness
Drowsiness
Black Box Warning
None
Contraindication/Caution:
Contraindication:
Caution:
The use of acrivastine during pregnancy or while breastfeeding should monitor with caution.
Pregnancy consideration:
Pregnancy category: B
Lactation: Excretion into human milk is unknown
Pregnancy Categories:     
Category A: well-controlled and Satisfactory studies show no risk to the fetus in the first or later trimester.
Category B: there was no evidence of risk to the fetus in animal studies, and there were not enough studies on pregnant women.
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.
Category N: There is no data available for the drug under this category.
Pharmacology
acrivastine’s mode of action is to selectively antagonize H1 receptors, which are found in various tissues, including the respiratory and vascular systems.
H1 receptors are activated by histamine, leading to symptoms like sneezing, itching, runny nose, and watery eyes during allergic reactions.
Pharmacodynamics
acrivastine competes with histamine for binding to H1 receptors, effectively blocking histamine’s actions. It reduces or prevents the allergic symptoms caused by histamine.
Pharmacokinetics
Absorption
acrivastine is rapidly absorbed from the gastrointestinal tract after oral administration.
Distribution
acrivastine is widely distributed throughout the body.
Metabolism
acrivastine undergoes minimal metabolism in the liver.
Elimination and excretion
acrivastine is excreted through the renal route.
Administration
acrivastine is available in the form of capsules for oral intake.
