Post-approval lifecycle
Variations framework	Variations classified per Thai FDA guidelines into major (require approval — e.g., new indication, formulation change, new manufacturing site) and minor (notification). New indications follow the new-drug pathway with SMP.	FDA classifies post-approval changes as: Annual Reportable, Changes Being Effected (CBE-0 immediate, CBE-30 with 30-day pre-implementation notice), and Prior Approval Supplements (PAS) — the most significant changes requiring FDA approval before implementation. Major manufacturing or labelling changes typically require a PAS.
Renewal cycle	Drug registration is valid indefinitely for most products once unconditional, subject to ongoing pharmacovigilance and GMP compliance; controlled substances and biologicals follow specific renewal cycles.	FDA does not require periodic renewal of NDAs or BLAs — approvals remain in effect indefinitely subject to compliance, payment of annual program fees, and post-marketing requirements. Annual reports are required.
Pharmacovigilance	Thai FDA's Health Product Vigilance Centre (HPVC) coordinates national ADR reporting (Thailand is a member of the WHO Programme for International Drug Monitoring, Uppsala). Marketing authorisation holders must submit PSURs aligned to ICH E2C(R2), report serious ADRs within statutory timelines, and maintain a Risk Management Plan (RMP) for new active substances. The SMP provides additional intensive monitoring for the first 2 years.	Mandatory expedited reporting of serious unexpected ADRs within 15 calendar days; periodic safety reports (PADERs/PAERs) for the first 3 years post-approval, then annually. PSURs in ICH E2C(R2) format accepted in lieu of PADERs by agreement. FAERS database receives spontaneous reports. Post-Marketing Requirements (PMRs) and Commitments (PMCs) tracked publicly.
