Non-base drugs are drugs other than base drugs.
On August 18, 2009, China officially promulgated the Implementation Opinions on Establishing the National Essential Drugs System, the Administrative Measures for the National Essential Drugs List (Provisional) and the National Essential Drugs List (equipped and used by primary medical and health institutions) (2009 edition), which marked the formal implementation of the establishment of the national essential drugs system in China.
The catalogue is constantly updated, and the essential drugs and non-essential drugs are also constantly changing.
I hope I can help you!
