Hi guys,

My original data is like below -

ABACAVIR 20 MG/ML
ABACAVIR 300 MG
ABACAVIR 300 MG / LAMIVUDINE 150 MG / ZIDOVUDINE 300 MG
ABACAVIR 600 MG / LAMIVUDINE 300 MG

I want to remove all the dosage info from the drug names, so they will become -

ABACAVIR
ABACAVIR
ABACAVIR / LAMIVUDINE / ZIDOVUDINE
ABACAVIR / LAMIVUDINE


Can any of you help me on this? Thanks a lot!
