"Baxter currently only has a 35% market share with those drugs and it believes that the PSA can help them increase market share to 70%."
Really? Sounds like your contradicting yourself. These devices enable the hospital to administer LESS drugs to the patient. So how is that going to help them increase market share and sell more over-priced drugs?
"So Baxter is marketing the PSA aggressively."
Highly unlikly. Only aggressively marketing this pump and dump scheme as witnessed by todays heavy selling.
