a) New drugs and indications approved at recent DAC meeting；
b) Addition of drugs not evaluated by DAC；
c) Changes in drug category status arising from funded programmes for
new drugs and expansion of safety net coverage;
d) Changes resulting from biennial comprehensive review as endorsed
by DMC; and
e) Deletion of drugs due to dormant use or product discontinuation.
