Tyzeka vs Baraclude US Scripts (Rolling and Raw)

[NRx=number of new prescriptions; TRx=number
of total prescriptions (new+renewal). For recently
launched drugs, the trend in NRx is an indictor of
what can be expected for TRx with a modest time lag.
Note that a prescription is counted as new whenever
it is newly written, even if is for a drug the patient is
already taking.

Caution: these numbers should not be taken too
literally inasmuch as the “comparable dates” may not
really be comparable. Still, I think it’s a worthwhile
presentation to get a general feel for the sales ramps.]
