Mechanism of Action: direct acting alpha agonist (1 & 2A) Indications: for the temporary relief of nasal (of the nose) congestion or stuffiness caused by hay fever or other allergies, colds, or sinus trouble . ], If accidentally ingested, standard methods to remove unabsorbed drugs should be considered. Oxymetazoline nasal should not be used for longer than 3 to 5 days. Conjunctival Congestion Ophthalmic. 2008;21(3) :449-54. doi ... Due to their vasoconstrictor action, the sympathomimetic decongestants oppose vasodilation, reducing nasal airway resistance and thus facilitating nose breathing. In addition, the local application of the drug also results in vasoconstriction due to its action on endothelial postsynaptic α 2 receptors; systemic application of α 2 agonists, in contrast, causes vasodilation because of centrally-mediated inhibition of sympathetic tone via presynaptic α 2 … [5], Due to its vasoconstricting properties, oxymetazoline is also used to treat nose bleeds[6][7] and eye redness due to minor irritation (marketed as Visine L.R. 2001 Nov;92(11):377-83. [, Mitrani P, Srinivasan M, Dodds C, Patel MS: Role of the autonomic nervous system in the development of hyperinsulinemia by high-carbohydrate formula feeding to neonatal rats. [, Druce HM, Ramsey DL, Karnati S, Carr AN: Topical nasal decongestant oxymetazoline (0.05%) provides relief of nasal symptoms for 12 hours. When administered intranasally, this action promotes drainage and improves ventilation. The risk or severity of hypertension can be increased when Oxymetazoline is combined with Aceclofenac. 1 receptors, the action of oxymetazoline results in vasoconstriction. Oxymetazoline. Match. By stimulating adrenergic receptors, oxymetazoline causes vasoconstriction of dilated arterioles and reduces blood flow.12 In a radioligand competition study, oxymetazoline displayed higher affinity at α1A-adrenoceptors compared to α2B-adrenoceptors, but with higher potency at α2B-adrenoceptors.5 When sprayed intranasally, oxymetazoline relieved relief nasal congestion and improved nasal airflow in patients with acute coryzal rhinitis for up to 12 hours following a single dose.10, Oxymetazoline binds to α1- and α2-adrenoceptors, which are Gq-protein-coupled receptors that promote vascular smooth muscle contraction by increasing intracellular calcium levels in response to ligand activation.17, Rosacea is a condition characterized by transient and persistent facial erythema. This activates the adrenal system to yield systemic vasoconstrction. [2] There is little consistency across the (relatively large) number of in-vitro studies with respect to binding affinity/selectivity. 1991 Apr 17;196(2):213-6. doi: 10.1016/0014-2999(91)90432-p. [. Flashcards. Citing an existing extensive body of evidence and noting a range of recommended periods from five to ten days, Novartis recommended the established five day period for its use for self-medication without medical consultation as it coincides with the typical duration of the common cold. 12.2 Pharmacodynamics. JAMA Ophthalmol. 2020 Oct 1. pii: 2771169. doi: 10.1001/jamaophthalmol.2020.3812. Pediatric Patients Nasal Congestion Intranasal. 1). One study classified it in the following order: α(2A) > α(1A) ≥ α(2B) > α(1D) ≥ α(2C) >> α(1B), but this is not universally agreed upon. The absence of an interaction does not necessarily mean no interactions exist. [citation needed] Effects on α receptors from systemically absorbed oxymetazoline hydrochloride may persist for up to 7 hours after a single dose. From the mid 1980s to mid 1990s, the brand Sinex was featured in many television advertisements. [clarification needed] There is no specific antidote for oxymetazoline, although its pharmacological effects may be reversed by α adrenergic antagonists such as phentolamine. PLAY. Alpha-adrenergic agonist; stimulates alpha-adrenergic receptors and produces vasoconstriction in the arterioles of the nasal mucosa. Humans: A Alpha-2A adrenergic receptor: antagonist. Oxymetazoline is found in many over-the-counter short-term nasal spray decongestant products as well as in ophthalmic drops for the relief of redness of the eyes associated with swimming, colds, or contact lens. After finding substantial early success as a prescription medication, it became available as an over-the-counter drug in 1975. J Pharm Sci. [citation needed] [8], In July 2020, oxymetazoline received approval by the FDA for the treatment of acquired drooping eyelid. Eur J Pharmacol. Your doctor may have special instructions on the proper use and dose for your medical problem. This decreases the amount of swelling and formation of mucus in the nose from the common cold, sinusitis, and upper respiratory allergies. [4], In the United States, oxymetazoline 1% cream is approved by the Food and Drug Administration for topical treatment of persistent facial erythema (redness) associated with rosacea in adults. 4. It produces local vasoconstriction, reduces blood flow, and causes shrinkage of mucosa which provides relief of nasal congestion Pharmacokinets of Oxymetazoline Absorption: Administered intranasally, occasional systemic absorption may occur. Terms in this set (10) brand name. 1995 Sep;116(1):1605-10. therapeutic class. MECHANISM OF ACTION. Oxymetazoline. 2010 Dec;24(6):729-39. doi: 10.1111/j.1472-8206.2009.00805.x. In producing vasoconstriction, the result is a decrease in blood flow in the nasal passages and consequently decreased nasal congestion. 1994 Dec;429(2):253-61. Both have similar effectiveness in reducing nasal congestion. 1 receptors, the action of oxymetazoline results in vasoconstriction. In addition, the local application of the drug also results in vasoconstriction due to its action on endothelial postsynaptic ? The therapeutic efficacy of Oxymetazoline can be decreased when used in combination with Acebutolol. Oxymetazoline is an alpha adrenoceptor agonist targeting a subset of adrenoreceptors in Mueller’s muscle of the eyelid. 2013 Apr;83(4):870-81. doi: 10.1124/mol.112.082313. [14] Vasoconstriction of vessels results in relief of nasal congestion in two ways: first, it increases the diameter of the airway lumen; second, it reduces fluid exudation from postcapillary venules. Mechanism of Action of Oxymetazoline (Eye Prep.) In that respect it is similar to phenylephrine. simplysara11. The dose of oxymetazoline selected for this experiment is greater than the EDs0 for i.t. The drug exerts its pharmacological action by acting as a selective alpha-1 adrenergic agonist. Trade Names: generic, Afrin ® Drug Class: Long- Acting Topical Nasal Decongestant. The drug exerts its pharmacological action by acting as a selective alpha-1 adrenergic agonist. [, Bende M, Loth S: Vascular effects of topical oxymetazoline on human nasal mucosa. The risk or severity of hypertension can be increased when Oxymetazoline is combined with Acemetacin. In nasal, it produces constriction, resulting in decreased blood … Alpha1A-adrenoceptor agonist; elicits vasoconstriction of the cutaneous microvasculature. [10] In a submission to the Therapeutic Goods Administration, a Novartis representative concluded, "The justification was not based on evidence." It reduces intraocular tension by constricting ciliary body blood vessels and produce mydriasis (without cycloplegia). 2003 Sep;41(3):167-74. Epub 2013 Jan 30. Intranasal application of oxymetazoline results in constriction of dilated arterioles and reduction in nasal blood flow and congestion… Oxymetazoline. Mechanism of Action. 1991 Sep 17;202(2):235-43. There is limited information on the clearance rate of oxymetazoline. In safety and efficacy studies, Study RVL-1201-201 and Study RVL-1201-202, the pharmacodynamics of UPNEEQ was assessed using an objective photographic measure, … Neurotransmission: The Autonomic and Somatic Motor Nervous Systems" (Chapter). Oxymetazoline is an imidazole derivative and a potent, direct-acting alpha (α)-adrenergic agonist with affinity to both α1- and α2-adrenoceptors.1 Oxymetazoline is available in various formulations with a wide variety of clinical implications.
