Ans: 1) Alphabetical
2) Morphological
3) Taxonomic
4) Pharmacological *** IMPORTANT
5) Chemical
6) Chemotaxonomical
Alphabetical
Ans: Merits:
-Easy and quick to use
-no repetition/ devoid confusion
-easy for system location, tracing and addition of drug entries
DEmerits:
-NO relationship between one drug to another drug
,Example: can't find the drug within the same family
