A Hartford Superior Court jury deliberated five hours Friday before finding Ridgefield-based Boehringer Ingelheim not liable for the severe internal bleeding a Florida man suffered after he used the relatively new blood thinner Pradaxa.

The verdict marks the third time this year a Connecticut jury has found in favor of the pharmaceutical company in such lawsuits. In one of the previous cases, plaintiffs said an 82-year-old woman’s death was caused by bleeding after taking Pradaxa. Covington & Burling and Shipman & Goodwin handled all three trials.
