FAQs

1. Are Indian and Chinese APIs acceptable for regulatory approval worldwide?
Yes. Many Indian and Chinese API manufacturers have achieved approvals from major regulators such as FDA and EMA. However, thorough documentation, validation, and audits are essential to demonstrate compliance.

2. What quality standards are mandatory when sourcing APIs for ophthalmic products?
APIs must meet pharmacopeial standards (USP, EP, IP), be manufactured under cGMP conditions, and be accompanied by comprehensive Certificates of Analysis.

3. How can companies ensure the reliability of API supply chains?
By engaging multiple certified suppliers, conducting routine audits, establishing long-term agreements, and maintaining safety stock inventories.

4. Are biosynthetic APIs being adopted for ophthalmic applications?
Though still emerging, biosynthetic APIs offer promising benefits in purity and sustainability but require regulatory validation before widespread ophthalmic use.
