subject_id	stay_id	charttime	med_rn	name	gsn_rn	gsn
16113983	37539106	2116-06-09 23:21:00	1	Ondansetron ODT	1	41562.0
12363835	34078373	2177-02-13 02:55:00	1	Cepacol (Menthol)	2	58921.0
12363835	34078373	2177-02-13 02:55:00	1	Cepacol (Menthol)	3	67735.0
12363835	34078373	2177-02-13 02:55:00	1	Cepacol (Menthol)	1	28283.0

`

My Question is why the same drug Cepacol (Menthol) for the same stay_ ID, their GSN_ RN and GSN values are different?
