Step 1: Understand the three pillars.
GMP (Good Manufacturing Practice), GLP (Good Laboratory Practice), and GCP (Good Clinical Practice) are quality standards for three different phases of drug development. GMP covers manufacturing, GLP covers laboratory testing, and GCP covers clinical trials.
Step 2: What are ICH guidelines?
ICH stands for the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use. ICH was created to harmonise regulatory requirements across the US, EU, and Japan so that drug data is mutually acceptable globally.
Step 3: How do ICH guidelines integrate all three?
ICH has multiple series: Q-series (Quality, covering GMP), S-series (Safety, covering GLP nonclinical studies), and E-series (Efficacy, covering GCP clinical trials). Together, these cover all three domains under one internationally recognised framework.
Step 4: Eliminate wrong options.
ISO 9001 is a generic quality management standard, not specific to pharma. WHO guidelines are international but do not integrate all three in a single harmonised framework like ICH. Schedule M is India-specific and covers only GMP.
Step 5: Confirm.
ICH guidelines are the globally recognised framework that integrates GMP, GLP, and GCP principles across major regulatory agencies.
