Bilastine Key Quality API Parameters: Buyers Should Know

Bilastine Key Quality API Parameters: Buyers Should Know

In the evolving arena of global allergy treatment, bilastine has emerged as a second-generation antihistamine offering targeted symptom control for allergic rhinitis and urticaria. 

In today’s world, the success of treatments relies on the quality of Active Pharmaceutical Ingredients (APIs). 

Understanding the quality of bilastine is important. This knowledge is important not only for formulators and clinical researchers but also for global API procurement officers.

BioSynth is a trusted API manufacturer in India. With over 80 years of experience, we focus on making bilastine and other important antihistaminic APIs. We dedicate ourselves to quality, traceability, and adhering to regulations.

In this article, we explore the science and manufacturing behind bilastine’s performance. We also discuss important quality metrics to note.

Additionally, we examine GMP-certified API exporters in India. One example is BioSynth. We are setting new standards for consistency and reliability in our batches.

Understanding Bilastine: Pharmacology Meets Precision Chemistry

Bilastine API is a nonsedating, selective histamine H1 receptor antagonist designed for oral use in allergic rhinitis and chronic urticaria. 

Unlike traditional antihistamines, bilastine has superior receptor affinity and a favorable pharmacokinetic profile, enabling long-lasting relief without CNS-related side effects.

To meet these clinical expectations, the quality of bilastine’s API becomes a pivotal control point.

Why API Quality is Crucial for Bilastine Based Formulations

Solubility and bioavailability: Micronized particle size specifications directly impact absorption.

 Impurity profile: Stringent control of related substances ensures safety in long-term use.

 Polymorphic stability: Different crystalline forms can alter dissolution and shelf life.

Residual solvent limits: Bilastine synthesis commonly involves class 2 solvents requiring tight specification limits as per ICH Q3C.

Failure to meet these bilastine quality parameters during manufacturing can compromise therapeutic outcomes, stability, and regulatory approvability.

Bio-Synth’s Commitment to High-Purity Bilastine API Manufacturing

At BioSynth, we make APIs with over 80 years of experience in pharmaceuticals. WHOGMP and ISO 9001:2015 certify our facilities in Hyderabad. Our dedicated production lines follow robust Good Manufacturing Practices (GMP) to ensure each batch of bilastine API meets stringent pharmacopoeial and client-specific requirements.

We leverage in-process analytical checks and validated stability protocols to ensure bilastine’s performance is consistent and compliant across geographies.

Key Quality Parameters for Bilastine API Buyers

As global demand for bilastine accelerates, especially across Europe, Asia-Pacific, and Latin America, procurement leaders must prioritize the following API quality parameters during vendor selection:

1. Assay (%): Should comply with 98.0%–102.0% specification via HPLC on an anhydrous basis.
2. Related Substances: Total impurities ≤ 0.5%, with any individual impurity ≤ 0.1% unless otherwise justified.
3. Residual Solvents: Compliance with ICH Q3C.
4. Heavy Metals: As per ICH Q3D (limits vary for Pb, Hg, As, Cd).
5. Moisture Content: Karl Fischer method ≤2.0%, ensuring stability in formulation.
6. Chiral Purity: Enantiomeric excess ≥99%, verified via chiral HPLC.
7. Micronization: D90 < 10 µm as per client specification for enhanced dissolution.

BioSynth supplies bilastine API with complete regulatory documentation, including:

1.  Certificate of Analyzed Data (COA)
2.  Drug Master File (DMF) availability
3.  Process Validation Data
4.  Impurity Profile with Safety Data
5.  ICH Compliant Stability Studies

How BioSynth Delivers Consistency Across Batches

Batch-to-batch consistency is often the Achilles’ heel of API manufacturing. At BioSynth, we use Process Analytical Technology (PAT) tools and a Quality by Design (QbD) approach. This ensures that every bilastine batch meets the required standards.

Our Compliance Framework:

1. ICH Q7 & Q3 Guidelines: Adherence from materials to finished API.
2. Change Control System: Ensuring transparency and regulatory alignment for any process adjustments.
3. Annual Product Reviews (APR): Comparative statistical analysis of batch trends.
4. TrendMonitoring Tools: Using software-based control charts, outlier and drift detection for impurity levels and particle size distribution.

Therapeutic Relevance: Bilastine’s Impact on Patient Quality of Life

In studies and clinical trials, bilastine has shown a significant improvement in patient quality of life (QoL). This is especially true in the RQLQ and DLQI areas:

1.  Nasal congestion and sneezing symptom resolution
2.  Sleep quality and fatigue reduction
3.  Fewer CNS related side effects vs cetirizine and levocetirizine
4.  Faster onset of action within 30 minutes
5.  Non-sedative profile favorable for working professionals

Data from global studies shows that quality of life scores improved along with symptom relief. This result depends, in part, on the quality of the API used in the final dosage form.

Regulatory Considerations When Sourcing Bilastine API from India

India is the world’s largest supplier of APIs by volume. However, buyers must perform stringent due diligence to ensure:

1.  GMP compliance: Check for WHO-GMP, cGMP (US FDA, EU-GMP) as applicable.
2.  Transparency in supply chain: Availability of impurity profile, genotoxic testing, etc.
3.  DMF availability: Mandatory for regulated markets.
4.  Audit readiness: Can the vendor host client audits without notice?
5.  Sustainability and ESG adherence: Increasingly prioritized by global pharma companies.

BioSynth meets and exceeds international benchmarks, ensuring that buyers can source bilastine APIs with confidence from India supported by traceability, documentation, and responsive technical support.
