	~~'''Acrivastine''' is a~~ [[~~second-generation antihistamine]] used to treat [[allergic rhinitis]] (such as [[hay fever]]) and [[urticaria]] (hives)~~. ~~It is known for its rapid onset~~ of ~~action and is often used in combination with [[pseudoephedrine~~]] ~~to relieve nasal congestion.~~		[[File:Acrivastine.svg\|thumb\|right\|Chemical structure of Acrivastine]]

	~~==Pharmacology==~~		'''Acrivastine''' is a [[second-generation antihistamine]] used in the treatment of [[allergic rhinitis]] and [[urticaria]]. It is known for its rapid onset of action and is often combined with [[pseudoephedrine]] to enhance its effects in relieving nasal congestion.
	Acrivastine is a [[~~histamine H1 receptor antagonist~~]]~~, which means it works by blocking~~ the ~~action~~ of [[~~histamine~~]]~~, a substance in the body that causes allergic symptoms. Unlike first-generation antihistamines, acrivastine is less likely to cause~~ [[~~drowsiness~~]] ~~because it does not cross the~~ [[~~blood-brain barrier~~]] ~~as easily~~.

	==~~Medical uses~~==		== Pharmacology ==
	Acrivastine is primarily used for the relief of symptoms associated with [[allergic rhinitis]] and [[chronic urticaria]]. These symptoms include [[sneezing]], [[runny nose]], [[itchy eyes]], and [[skin rash]].

	~~==Side effects==~~		Acrivastine is a [[histamine H1 receptor antagonist]], which means it works by blocking the action of [[histamine]], a substance in the body that causes allergic symptoms. Unlike first-generation antihistamines, acrivastine has minimal [[sedative]] effects, making it suitable for daytime use.
	~~Common side effects of acrivastine include~~ [[~~headache~~]], [[~~dry mouth~~]], ~~and [[drowsiness]]~~. ~~Although it is less sedating than~~ first-generation antihistamines, ~~some patients may still experience drowsiness~~.

	==~~Contraindications~~==		=== Mechanism of Action ===
	~~Acrivastine should not be used in individuals with severe [[kidney impairment]] or those who are [[hypersensitive]] to acrivastine or any of its components.~~

	~~==Interactions==~~		Acrivastine competes with histamine for binding at the H1 receptor sites on effector cells in the [[gastrointestinal tract]], [[blood vessels]], and [[respiratory tract]]. This prevents the typical allergic response, such as [[sneezing]], [[itching]], and [[runny nose]].
	Acrivastine ~~may interact~~ with ~~other medications that cause drowsiness~~, such as [[~~alcohol~~]], [[~~benzodiazepines~~]], and ~~other~~ [[~~antihistamines~~]]~~. It is important to consult a healthcare provider before combining acrivastine with other medications~~.

	==~~Dosage~~==		== Clinical Use ==
	The typical dosage of acrivastine for adults and children over 12 years of age is 8 mg, taken up to three times a day. It is important to follow the prescribed dosage and not exceed the recommended amount.

	==~~Mechanism of action~~==		Acrivastine is primarily used to treat symptoms associated with [[seasonal allergic rhinitis]] and [[chronic idiopathic urticaria]]. It is effective in reducing symptoms such as [[sneezing]], [[nasal congestion]], and [[itchy eyes]].
	Acrivastine ~~works by selectively inhibiting the H1 receptor~~, ~~which prevents histamine from binding~~ to ~~its receptor~~ and ~~causing allergic symptoms~~. ~~This action helps alleviate~~ the ~~symptoms~~ of ~~allergies without significantly affecting~~ the ~~central nervous system~~.
			=== Dosage and Administration ===

			Acrivastine is typically administered orally. The usual adult dose is 8 mg, taken up to three times a day. It is often available in combination with pseudoephedrine, marketed under various brand names.

			== Side Effects ==

			Common side effects of acrivastine include [[headache]], [[drowsiness]], and [[dry mouth]]. Although it is less sedating than first-generation antihistamines, some patients may still experience drowsiness.

			== Contraindications ==

			Acrivastine should not be used in individuals with known hypersensitivity to the drug or any of its components. Caution is advised in patients with [[renal impairment]] due to the drug's excretion through the kidneys.
