Product Introduction
Clarithromycin Bulk is a pharmaceutical breakthrough for a excessive purity lively pharmaceutical ingredient inside the macrolide antibiotic own family. It is chemically 6-o-methylerythromycin, cas range 81103-eleven-9, and is a white to off white crystalline powder this is more acid solid than erythromycin. The strategic methylation at c-6 function substantially complements oral bioavailability with little gastrointestinal adverse occasions. It has a molecular weight of 747.95 g/mol and a chemical components of c38h69no13 . It has appropriate lipophilicity which helps better penetration into tissues specifically respiration tissues and macrophages. Our product is a high grade raw cloth for the manufacture of numerous antibiotic formulations for breathing infections and for h. Pylori eradication therapy. It has a steady 99% purity and conforms to all major pharmacopoeial standards.

Third-Party Test Report
Independent Testing for Quality Assurance: Shaanxi Hongda partners with across the world recognized third-birthday party testing laboratories like as sgs and eurofins to conduct rigorous analytical verifications outdoor of our personal exceptional control systems.
Pesticide Residue Analysis : Multi-residue screening with the aid of GC-MS/msMS and LC-MS/MS technologies verify compliance with european and FDA limits delivering pharmaceutical grade purity for safe human intake.
Heavy Metal Testing: ICP-MS analysis confirms that lead, arsenic, cadmium and mercury are far below the limits defined in ICH Q3D guidelines, ensuring patient safety and compliance with regulatory standards.
Microbiological Testing: Confirmed to USP <61> and <62> for total viable aerobic count, yeast and mould counts and absence of pathogens including E. coli, Salmonella and Staphylococcus aureus.
Residual Solvent Testing: Gas chromatography testing confirms that the residual solvents used in the production process are within the permitted limits for ICH Q3C Class 2 and Class 3 solvents, ensuring product safety.

Clarithromycin Powder Advantages
Enhanced Acid Stability: The methylation alteration at C-6 position gives remarkable stability in acidic stomach conditions, leading in 50% greater bioavailability compared to erythromycin and more predictable therapeutic effects.
Superior Tissue Penetration: High lipophilicity helps top notch distribution into breathing tissues, reaching lung tissue concentrations 10-20 times more than serum tiers, making it specifically effective towards respiration infections.
Increased Half-Life: Serum 1/2-lifestyles of 3-7 hours (extended to 5-9 hours for the energetic metabolite) enables for easy twice-daily dosage, improving affected person compliance and healing success fees.
Broad Antimicrobial Spectrum: Effective against a wide range of Gram-positive bacteria, atypical pathogens including Mycoplasma and Chlamydia, and Helicobacter pylori, providing versatile therapeutic applications across multiple infection types.
Fewer gastrointestinal side effects: The structural change greatly reduces the motility-stimulating consequences that are usually related to erythromycin, ensuing in higher affected person tolerance and a lower rate of remedy termination.
Enhanced Manufacturing Characteristics: Our micronised product gives a uniform particle size distribution and glide traits, ensuing in uniform content in strong dosage forms and simplicity of formula improvement.
Clarithromycin Powder Application
Respiratory Tract Infection Formulations: The powder is the energetic element within the formula of pills and capsules for the treatment of community-obtained pneumonia, acute bacterial exacerbations of persistent bronchitis and acute maxillary sinutitis where penetration into tissues is essential to efficacy.
Helicobacter Pylori Eradication Therapies: It is an important component of triple and quadruple therapy regimens. It is used in combination with proton pump inhibitors and other antibiotics to provide more than 90% eradication in the management of peptic ulcer disease.
Skin & Soft Tissue Infection Products: Developed oral dosage forms for the treatment of simple skin infections caused by Staphylococcus aureus and Streptococcus pyogenes, providing viable options for outpatient treatment.
Mycobacterial Disease Prevention: Utilized in specific formulations for prophylaxis and treatment of Mycobacterium avium complex (MAC) infections in immunocompromised individuals, particularly those with HIV/AIDS, requiring strict potency consistency.
Pediatric Suspension Preparations: The powder is processed into taste-masked granules for reconstitution, offering age-appropriate formulations for treating otitis media and pharyngitis in children with exact dosing flexibility.
Extended Release Formulation Development: Manufacturers use the substance to formulate extended-release tablets for once-daily administration that increase convenience and compliance for chronic infection care while preserving therapeutic plasma concentrations.
Production Process
Step 1 - Base Compound Fermentation: Manufacturing begins with the fermentation of saccharopolyspora erythraea underneath regulated circumstances to yield erythromycin a as the base compound. The erythromycin base is of excessive purity and manufactured to a regular grade for chemical modification.
Step 2 - Chemical Methylation Reaction: Erythromycin is selectively methylated at the 6-hydroxyl site by methylating agents under carefully controlled temperature and pH conditions . Result: 6-O-methylerythromycin (clarithromycin) was obtained with good conversion efficiency and low by-product formation.
Step 3 - Purification and Crystallisation: The crude product of the reaction is purified by many steps such as solvent extraction, activated carbon treatment and controlled crystallisation in pharmaceutical grade solvents. Result: Crystals of Clarithromycin Powder of high purity according to pharmacopoeial requirements are obtained.
Step 4 - Drying and Micronization: The purified crystals are dried in vacuum at managed temperature and jet milled to obtain the most efficient particle length distribution for pharmaceutical components. Result: pleasant uniform powder with steady particle properties which guarantees extremely good content consistency in dosage paperwork.
Step 5 - Quality Testing and Release: Each production batch is tested extensively including assay determination by HPLC, impurity profiling, residual solvent analysis, heavy metal testing and microbiological examination. Quality packing and release are only approved for batches that fulfil all internal and pharmacopoeial criteria.
Step 6 - Packaging and Storage: The approved powder is filled into double-layer PE bags in fibre drums (25kg net weight) under controlled humidity and kept in temperature-controlled warehouses. Result: Full batch traceability documentation and product stability throughout shelf life.
