Olopatadine hydrochloride Chemical Properties,Usage,Production
Description
Olopatadine hydrochloride is an ophthalmic antihistamine that inhibits release of histamine from mast cells and is a relatively selective histamine H1 antagonist. It inhibits type 1 immediate hypersensitivity reactions. Olopatadine hydrochloride is indicated in the temporary relief of itching caused by allergic conjunctivitis. H1 antagonists have an established and valued place in the symptomatic treatment of various immediate hypersensitivity reactions. In addition, the central properties of some of the series are of therapeutic value for suppressing motion sickness or for sedation.
Chemical Properties
White Solid
Originator
Kyowa Hakko (Japan)
Uses
Dual acting histamine H1-receptor antagonist and mast cell stabilizer. Antiallergic; antihistaminic.
Uses
Olopatadine hydrochloride is a potent, selective antagonist of the H1 histamine receptor (Ki = 16-41.1 nM), with much lower affinities for the H2 and H3 receptors (Ki = 43.4 and 172 μM, respectively). It blocks histamine-induced phosphoinositide turnover in isolated cells (IC50 = 9.5-39.9 nM) and prevents passive cutaneous anaphylaxis in rats (ED50 = 49 μg/kg) and anaphylactic bronchoconstriction in guinea pigs (ID50 = 30 μg/kg). Olopatadine is effective in treating allergic rhinitis and conjunctivitis. It also suppresses itch in patients with well-controlled chronic urticaria. In humans, this antihistamine does not cause cognitive or psychomotor impairment at therapeutic doses.[Cayman Chemical]
Preparation
Olopatadine hydrochloride can be prepared in five steps from the sodium salt of phydroxyphenylacetic acid methyl ester with phthalide.
Definition
ChEBI: Olopatadine hydrochloride is a dibenzooxazepine.
brand name
Patanol (Alcon).
Pharmacokinetics
Olopatadine hydrochloride was launched in the US for use in allergic conjunctivitis. It has a fast onset of action with a long duration of action (due to slow dissociation kinetics) that combines the ability to prevent human conjunctival mast cell mediator release with selective H1-receptor antangonistic activity (greater H3:H1 selectivity than H2:H1 selectivity). In addition, Olopatadine hydrochloride had no inhibition of 5-lipoxygenase, PAF acetyltransferase and thromboxane synthase while interfering with phospholipase A2. It has a presynaptic inhibition of tachykinin release and inhibits bronchial sensory nerves through activation of small conductance calcium activated potassium channels. It was more potent than ketotifen and terfenadine and was effective at inhibition of PAF, LTC4 induced conjunctivitis and TXB2 production. It does not accumulate in the CNS, has a low affinity for H1-receptors in the brain, and significantly inhibits allergen induce sneezing. Olopatadine hydrochloride was more effective in conjuctival than in corneal or the trabecuiar meshwork cells.
Veterinary Drugs and Treatments
Olopatadine HCl is a selective H1 receptor antagonist and inhibitor of histamine release from mast cells. It is marketed for topical use to alleviate symptoms of allergic conjunctivitis in humans and is thought to be safe for use in children three years of age and older. Olopatadine, upon topical application in humans, was shown to have very limited systemic absorption. It was detectable in the milk of nursing rats, after topical application, and like most medications should be avoided in pregnant or nursing animals.
