Introduction
Navigating the complex supply chain of active pharmaceutical ingredients (APIs) is vital for stakeholders involved in manufacturing, distribution, and procurement of prescription medicines. The drugs Promethazine Hydrochloride and Phenylephrine Hydrochloride with Codeine Phosphate are widely used for their sedative, antihistamine, and cough suppressant properties, respectively. Their procurement hinges on identifying reliable suppliers capable of meeting regulatory standards, optimizing costs, and ensuring consistent quality.
1. Overview of Promethazine Hydrochloride and Phenylephrine Hydrochloride with Codeine Phosphate
Promethazine Hydrochloride serves primarily as an antihistamine for allergy relief, antiemetic, and sedative purposes. Its broad therapeutic uses necessitate a stable supply chain from multiple producers to prevent shortages.
Phenylephrine Hydrochloride with Codeine Phosphate combination is commonly available as a cough syrup or oral solution, offering rapid symptomatic relief. Due to the inclusion of codeine, a controlled substance, suppliers must adhere to stringent regulatory controls.
2. Global Manufacturing and Major Supplier Landscape
Promethazine Hydrochloride
The global manufacturing footprint includes leading API producers in countries such as India, China, and Italy. Notably:
-
Zhejiang Hisun Pharmaceutical Co., Ltd. (China): A prominent manufacturer offering high-quality Promethazine Hydrochloride as part of its extensive API portfolio.
-
Aarti Industries Ltd. (India): Provides a robust supply of Promethazine Hydrochloride, with facilities meeting cGMP standards.
-
Kinotech (India): Specializes in fine chemicals and APIs, including Promethazine Hydrochloride, with export capabilities to North America and Europe.
Phenylephrine Hydrochloride with Codeine Phosphate
Given the controlled status of codeine, suppliers generally APIs separately for phenylephrine and codeine, with formulations ensuring compliance with local regulations:
-
Sun Pharmaceutical Industries Ltd. (India): Supplies both phenylephrine and codeine APIs, with extensive regulatory compliance for controlled substances.
-
Malesci (Italy): Specializes in advanced APIs for controlled substances, providing high-quality codeine phosphate.
-
Siegfried AG (Switzerland): Offers phenylephrine APIs, with robust quality assurance protocols.
3. Regulatory and Compliance Considerations
Suppliers must demonstrate compliance with:
- Good Manufacturing Practices (GMP): Ensures safety, quality, and efficacy.
- Controlled Substances Regulations: Particularly for APIs like codeine, which are classified under strict legal frameworks (e.g., DEA regulations in the U.S.).
- Certifications: ISO certifications, certifications of compliance with pharmacopeial standards (USP, EP, BP).
Note: Some suppliers operate under strict licensing agreements for controlled substances, impacting procurement logistics and costs.
