Lastin (Azelastine Hydrochloride)

Azelastine hydrochloride works by selectively blocking H1‑histamine receptors in the nasal mucosa, preventing histamine‑induced inflammation and sensory nerve activation. It also stabilises mast cells, limiting the release of additional inflammatory mediators that contribute to allergic symptoms.

The appropriate dose of Lastin is determined by a qualified healthcare professional based on the patient’s age, severity of symptoms, and clinical response. Patients should follow the prescriber’s instructions and the product label for proper administration.

Safety data for azelastine during 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.

To order Lastin, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will request trade or institutional credentials before providing pricing, availability, shipping details and any necessary import documentation.

Lastin contains azelastine, a second‑generation antihistamine with both H1‑receptor antagonism and mast‑cell stabilising properties. Compared with first‑generation antihistamines, it typically causes less sedation and offers rapid symptom relief when administered intranasally.

Store Lastin at room temperature, below 25 °C, in its original packaging. Protect the spray from moisture, excessive heat and direct sunlight to maintain product stability and potency.

Lastin is administered as a nasal spray. The patient should gently blow the nose, tilt the head slightly forward, insert the nozzle into one nostril, and spray the prescribed number of sprays while breathing in gently. The procedure is repeated in the other nostril if directed by the prescriber.

Serious adverse reactions, although rare, include anaphylaxis, angioedema, severe bronchospasm, persistent nosebleeds, and significant visual disturbances. Any signs of severe allergic reaction or respiratory difficulty should prompt immediate medical attention.

Lastin should be avoided in individuals with known hypersensitivity to azelastine or any component of the formulation. Patients with uncontrolled asthma, severe nasal obstruction, or those who have experienced serious reactions to other antihistamines should consult a healthcare professional before use.
