(Alliance News) - A US senator has accused AstraZeneca PLC, GSK PLC, AbbVie Inc and other drugmakers of "abusing" the patent system to send prices higher, Bloomberg reported on Thursday.
The drugmakers have been accused of making sham patents to send prices higher and clip the wings of competition, the news agency reported, citing letters from Democrats Elizabeth Warren and Pramila Jayapal.
Astra's Symbicort asthma treatment and GSK's Advair and Flovent pair of inhalers are among the products mentioned in a letter sent by Warren to the drugmakers.
