Tyzeka: US Weekly Scripts by Month

NRx=number of new prescriptions; TRx=number
of total prescriptions (new+renewal). For recently
launched drugs, the trend in NRx is an indicator of
what can be expected for TRx with a modest time lag.
NRx% and TRx% are calculated as NRx and TRx
divided by the number of new and total prescriptions,
respectively, for all drugs in the HBV category. (A
prescription is counted as new whenever it is newly
written, even if the patient is already taking the drug.)
