Lastin (Azelastine Hydrochloride)

Azelastine hydrochloride works by selectively blocking H1‑histamine receptors in the nasal mucosa, preventing histamine‑mediated inflammation and sensory nerve activation. This antagonism reduces vasodilation, vascular permeability, and the release of inflammatory mediators, leading to decreased nasal swelling and irritation.

The dosing regimen for Lastin is determined by a qualified prescriber based on the patient’s age, severity of symptoms, and clinical response. Typically, one or two sprays per nostril are used, but the exact number and frequency should follow the healthcare professional’s instructions.

Safety data for azelastine hydrochloride in pregnancy and lactation are limited. Women who are pregnant, planning to become pregnant, or breastfeeding should discuss potential risks and benefits with their healthcare provider before using Lastin.

GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any required import documentation.

Lastin contains azelastine, a second‑generation antihistamine with both antihistaminic and anti‑inflammatory properties. Compared with first‑generation sprays, azelastine generally causes less sedation. Its rapid onset and dual action often provide quicker symptom relief than some older agents, while maintaining a favorable safety profile.

Lastin should be stored at room temperature, away from direct sunlight and excessive heat. Keep the spray in its original packaging to protect it from moisture. Do not freeze the product, and ensure the nozzle is clean and free of debris before each use.

Lastin is administered as a nasal spray. The user gently inserts the tip into one nostril, closes the opposite nostril, and sprays the prescribed number of actuations while breathing in gently. The process is repeated in the other nostril if required, following the prescriber’s directions.

While most users experience only mild side effects, serious risks include nosebleeds (epistaxis), severe allergic reactions such as anaphylaxis, and nasal ulceration or crusting. If any of these occur, discontinue use immediately and seek medical attention.

Individuals with known hypersensitivity to azelastine hydrochloride or any component of the spray should avoid using Lastin. Patients with severe nasal obstruction, recent nasal surgery, or those taking monoamine oxidase inhibitors should consult a healthcare professional before use.
