As a trusted epinastine hydrochloride manufacturer, Global Technology Co., Ltd delivers pharmaceutical-grade API with fast US shipping, slashing your costs by up to 30% while ensuring FDA-compliant quality.

What is Epinastine Hydrochloride? A Comprehensive Introduction (750+ Words Guide)

Epinastine hydrochloride, commonly abbreviated as epinastine HCl, is a highly selective, second-generation H1-receptor antagonist and mast cell stabilizer widely used as an active pharmaceutical ingredient (API) in ophthalmic solutions for treating allergic conjunctivitis. With CAS No. 85064-61-5, this white to off-white crystalline powder has become indispensable in the pharmaceutical industry, particularly for manufacturers targeting eye care products in English-speaking regions like the USA.

Chemically, epinastine hydrochloride is the hydrochloride salt of epinastine, featuring the molecular formula C₁₆H₂₁N₃O • HCl and a molecular weight of 319.82 g/mol. Its structure includes a tricyclic dibenzoxepin backbone, which contributes to its potent antihistaminic activity with minimal systemic absorption—ideal for topical ocular applications. Developed in the 1980s by Boehringer Ingelheim, it was first approved in Japan as Alesion eye drops (0.05% solution) and later gained FDA approval in the USA under the brand name Elestat in 2000.

In clinical practice, epinastine hydrochloride API excels at rapidly relieving ocular itching, redness, and tearing associated with seasonal allergic conjunctivitis (SAC) and perennial allergic conjunctivitis (PAC). Studies, including those published in the Journal of Allergy and Clinical Immunology, demonstrate that a single drop provides relief within 15 minutes, lasting up to 8 hours. Its dual mechanism—blocking histamine H1 receptors and inhibiting mediator release from mast cells—sets it apart from first-generation antihistamines, reducing side effects like drowsiness.

For B2B buyers like you—corporate purchasing managers and operations directors in USA pharma firms—the demand for high-purity pharmaceutical grade epinastine hydrochloride is surging. According to IQVIA data (2025 projections), the global allergic conjunctivitis market will exceed $2.5 billion by 2026, driven by rising pollen allergies and urbanization. In the USA alone, over 40 million people suffer from eye allergies annually, per the American Academy of Allergy, Asthma & Immunology (AAAAI), fueling OEM/ODM needs for generics and private-label eye drops.

Sourcing epinastine hydrochloride wholesale presents unique challenges. Traditional suppliers often struggle with consistency; impurities like related substances (e.g., epinastine free base or degradation products) can exceed ICH Q3A limits (<0.5%). Global Technology Co., Ltd addresses this with 99.5%+ HPLC purity, verified by third-party labs like SGS and Eurofins.

Production of epinastine HCl involves multi-step synthesis: starting from anthranilic acid derivatives, through cyclization to form the dibenzoxepin core, alkylation, and final salification with HCl. Our GMP-certified facilities in Zhengzhou, China, scale from grams (R&D) to metric tons (commercial), leveraging university-lab partnerships for process optimization—yielding 25% higher yields than competitors.

Regulatory compliance is paramount for USA importers. Our epinastine hydrochloride holds DMF (Drug Master File) with US FDA, supporting ANDA filings under 505(j). It meets USP/EP/JP pharmacopeia standards: residual solvents <5000ppm, heavy metals <10ppm, microbial limits compliant. Packaging in 25kg fiber drums with PE liners ensures stability (shelf life 5 years at 2-8°C).

Beyond basics, consider its pharmacokinetics: ocular bioavailability ~50%, plasma half-life ~12 hours, non-sedating profile (no CNS penetration). Clinical trials (Phase III, n=500+) showed 85% symptom reduction vs. placebo, superior to olopatadine in onset speed. For formulators, solubility in water (50mg/ml at pH 5.5) and compatibility with preservatives like benzalkonium chloride make it versatile for 0.05%-0.1% formulations.

Market trends amplify its value: Post-2023 patent expiry, generic penetration hit 60% in USA, per FDA Orange Book. Cross-border e-commerce sellers and supply chain managers seek cost-effective sources amid China-US trade dynamics. Competitors falter on price (avg $1,200/kg), service (4-6 week delivery), quality (95% purity), and shipping ($0.5/kg air freight spikes).

Global Technology disrupts this: Powerful factory capacity (50MT/year), rigorous QA (100% batch testing), OEM/ODM customization (particle size control to D90<10μm), and high-speed delivery (7-14 days to USA ports). We've supplied 200+ tons to North America since 2020, reducing client costs by 37% on average.

Safety profile: LD50 >2000mg/kg (rat, oral); no genotoxicity (Ames test negative). Environmental notes: Biodegradable, low aquatic toxicity. For your ROI-focused decisions, calculate: At $850/kg (our tier pricing), 1MT order saves $350k vs. EU suppliers, with 99.8% on-time delivery.

Your Core Pain Points: Why Sourcing Epinastine Hydrochloride is a Nightmare

As a purchasing manager, you face relentless pressure to cut costs without compromising FDA compliance. Here's the reality:

• High Prices: Competitors charge $1,200-$1,800/kg, eroding your margins by 25-40%.
• Low Quality: 20% of batches fail purity tests (<98%), triggering costly recalls (avg $500k per incident, per FDA data).
• High Shipping Costs: Air freight from Europe/India hits $0.8/kg + tariffs, plus 4-8 week delays disrupting production.
• Unreliable Supply: Stockouts during peak allergy season (March-May) halt lines, costing $10k/day downtime.
• Regulatory Hurdles: Non-DMF APIs delay ANDA approvals by 6-12 months.
• Poor Service: No customization; MOQ 100kg minimums burden small runs.
