Cetirizine Dihydrochloride Properties:
1. Physical Appearance: Cetirizine dihydrochloride is typically found as a white, crystalline powder. It may also be processed and formulated into various dosage forms, such as tablets, capsules, or syrups.
2. Solubility: Cetirizine dihydrochloride is freely soluble in water. It is more soluble in water than in organic solvents like ethanol or chloroform.
3. Pharmacological Properties: Cetirizine dihydrochloride is a selective antagonist of peripheral H1 receptors. It exerts its antihistaminic effects by competitively binding to the H1 receptors, thereby blocking the actions of histamine, which is released during allergic reactions. By doing so, it helps alleviate allergy symptoms such as sneezing, runny nose, itching, and watery eyes.
4. Pharmacokinetics: After oral administration, cetirizine dihydrochloride is rapidly absorbed from the gastrointestinal tract, with peak plasma concentrations occurring within 1 to 2 hours. It is primarily eliminated unchanged via the kidneys, with an elimination half-life of approximately 10 hours in adults.
5. Medical Uses: Cetirizine dihydrochloride is commonly used to relieve symptoms of allergic rhinitis (hay fever) and urticaria (hives) in adults and children. It may also be prescribed for other allergic conditions, as determined by a healthcare professional.
6. Dosage Formulations: Cetirizine dihydrochloride is available in various dosage forms, including tablets, chewable tablets, oral syrups, and sometimes as a component in combination medications for cold and allergy relief.
7. Side Effects: Like all medications, cetirizine dihydrochloride can cause side effects in some individuals. Common side effects may include drowsiness, dry mouth, headache, and stomach discomfort. However, it is generally considered a non-sedating antihistamine, meaning it is less likely to cause significant drowsiness compared to older antihistamines.
