Key Factors in Selecting API Sources for Thyro-Tabs

1. Quality and Regulatory Compliance

Suppliers must adhere to Good Manufacturing Practices (GMP), with APIs meeting USP, EP, or JP standards. Certificates of Analysis (CoA), validation reports, and stringent analytical testing are non-negotiable in ensuring API purity, potency, and stability.

2. Supply Chain Stability and Capacity

Reliable supply chains mitigate risks of shortages that can disrupt Thyro-Tabs production. Leading suppliers maintain large-scale manufacturing capabilities, buffer stock, and contingency planning for geopolitical or logistical disruptions.

3. Cost & Economic Factors

While quality remains paramount, cost competitiveness influences procurement, especially for generic formulations. Chinese and Indian manufacturers typically offer more competitive pricing but require thorough validation and ongoing quality audits.

4. Technology Transfer & Process Compatibility

Compatibility with existing manufacturing processes in producing Thyro-Tabs is essential. Suppliers often provide technical support facilitating seamless integration of APIs into finished formulations.
