Santarus CEO Discuses Q1 2013 Results - Earnings Call Transcript, Seeking alpha may 6th 2013: From 1st quarter - Q/A answer to question about price increases:
"We typically would take price increase on a product; usually we look at it anywhere from once to twice a year and it just depends on the market opportunity.
Just want to add, in the first quarter we had taken an 8% price increase on GLUMETZA, so that would be reflected in the financial results and then on our smaller products we had also taken some modest price increases towards the end of the quarter."
I don't know if it was mentioned more recently, also. This was what I found looking at recent transcripts.
