Nolodon
Nolodon Uses, Dosage, Side Effects, Food Interaction and all others data.
Nolodon, an antihistamine, works by blocking the action of histamine in the body, which reduces allergy symptoms. Nolodon Hydrochloride treats sneezing, itching, runny nose, and other nasal symptoms of allergies. Nolodon Nasal Spray contains 0.6% w/v Nolodon (base) in a nonsterile aqueous solution with pH of approximately 3.7. After initial priming (5 sprays), each metered spray from the nasal applicator delivers 100 microliters of the aqueous solution containing 665 mcg of olopatadine Hydrochloride, which is equivalent to 600 mcg of Nolodon (base). Nolodon Nasal Spray also contains benzalkonium chloride (0.01%), dibasic sodium phosphate, edetate disodium, sodium chloride, hydrochloric acid and/or sodium hydroxide (to adjust pH), and purified water.
Inflammatory reactions in response to various stimuli are mediated by endogenous mediators and other pro-inflammatory factors. Histamine receptor activation and mast cell degranulation are primary mechanisms that cause inflammatory reactions such as ocular itching, hyperemia, chemosis, eyelid swelling, and tearing of seasonal allergic conjunctivitis. Nolodon is an anti-allergenic molecule and mast cell stabilizer that inhibits the in vivo type 1 immediate hypersensitivity reaction. By blocking the effects of histamine, olopatadine works to reduce the symptoms of allergies and inflammation at various sites of administration, including the eyes and nose. It has shown to exert antihistaminic effects in isolated tissues, animal models, and humans. Nolodon also demonstrated dose-dependent inhibition of immunologically-stimulated release of histamine from rat basophilic leukemia cells and human conjunctival mast cells in vitro. Nolodon has a relatively rapid onset of action and prolonged duration, where it was shown to mediate anti-histaminic effects at 5 minutes to 24 hours post-administration.
While olopatadine is a non-sedating antihistamine agent, there have been reports of somnolence in some patients taking nasal olopatadine during clinical trials. Temporary blurred vision or other visual disturbances were observed following ophthalmic administration. Nolodon has negligible effects on alpha-adrenergic, dopamine, muscarinic type 1 and 2, and serotonin receptors. In clinical trials, there was no evidence of any effect of olopatadine on QT prolongation was observed following intranasal administration.

Uses
Nolodon Nasal Spray is an H1 receptor antagonist used for the relief of the symptoms of seasonal allergic rhinitis in adults and children 6 years of age and older.
Nolodon is also used to associated treatment for these conditions: Allergic Rhinitis (AR), Seasonal Allergic Conjunctivitis, Seasonal Allergic Rhinitis
How Nolodon works
Histamine is a biogenic vasoactive amine that binds to its receptors, which are G-protein coupled receptors. Signaling through the histamine H1 receptor is thought to primarily promote the activation of inflammatory reactions, such as allergy, asthma, and autoimmune diseases. H1 receptor signaling activates the intracellular transcription factors, such as IP3, PLC, PKC, DAG, and intracellular calcium ions, which all work to activate further downstream cascades. Activated downstream cascades lead to the production of cytokines, the release of mast cell inflammatory mediators, synthesis of prostacyclins, activation of platelet factor, as well as the synthesis of nitric oxide, arachidonic acid, and thromboxane, which all contribute to inflammatory reactions.
Nolodon is an anti-allergic molecule that works via several mechanisms. As a mast cell stabilizer, it stabilizes rodent basophils and human conjunctival mast cells and inhibits the immunologically-stimulated release of histamine. Nolodon acts as an antagonist at the histamine H1 receptors with high selectivity, which is explained by a unique receptor binding pocket that consists of the aspartate residue in the third transmembrane helix and other sites in the H1 receptor. Upon binding, olopatadine blocks the H1 receptor signaling pathway, inhibiting the release of inflammatory mediators, such as tryptase, prostaglandin D2, TNF-alpha, as well as pro-inflammatory cytokines. It also decreases chemotaxis and inhibits eosinophil activation. In vitro, olopatadine was shown to inhibit epithelial cell intercellular adhesion molecule-1 (ICAM-1), which promotes the recruitment of migrating pro-inflammatory mediators.
Dosage
Nolodon dosage
Adults and Adolescents 12 years of age and older: Two sprays per nostril twice daily.
Children 6 to 11 years of age: One spray per nostril twice daily.
Administer NolodonNasal Spray by the intranasal route only.
Side Effects
A bitter taste in the mouth, nosebleeds, or irritation/soreness in the nose may occur. Drowsiness may rarely occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Toxicity
Based on the findings of an acute toxicity study in animals, the oral LD50 of olopatadine was >1150 mg/kg in mice and >3870 mg/kg in rats. The Lowest published toxic dose via the oral route was 20 mg/kg in rat and 0.1 mg/kg in mouse.
There are no known reports on overdosage following oral, ophthalmic, or intranasal administration of olopatadine. Likely symptoms of antihistamine overdose may include drowsiness in adults and, initially, agitation and restlessness, followed by drowsiness in children. In case of suspected overdose, supportive and symptomatic treatment is recommended.
Precaution
Before initial use, Nolodon Nasal Spray by releasing 5 sprays or until a fine mist appears. When Nolodon Nasal Spray has not been used for more than 7 days, re-prime by releasing 2 sprays. Avoid spraying Nolodon Nasal Spray into the eyes. Patients should be informed to avoid spraying Nolodon Nasal Spray in their eyes.

Ocular administration of olopatadine in healthy subjects resulted in the Cmax of 1.6 ± 0.9 ng/mL, which was reached after about 2.0 hours. The AUC was 9.7 ± 4.4 ngxh/mL.
The average absolute bioavaiability of intranasal olopatadine is about 57%. Following intranasal administration in healthy subjects, the Cmax of 6.0 ± 8.99 ng/mL at steady-state was reached between 30 minutes to 1 hour after twice daily intranasal administration. The average AUC was 66.0 ± 26.8 ng·h/mL. In patients with seasonal allergic rhinitis, the Cmax of 23.3 ± 6.2 ng/mL at steady-state was reached between 15 minutes and 2 hours post-dosing and the average AUC was 78.0 ± 13.9 ng·h/mL.

Pregnancy & Breastfeeding use
Pregnancy Category C; No adequate and well-controlled studies in pregnant women have been conducted. Nolodon Nasal Spray should be used in pregnant women only if the potential benefit to the mother justifies the potential risk to the embryo or fetus.
