A new Canadian study finds that a drug now involved in Risperdal lawsuits, as well as several other antipsychotics, may carry an increased risk for kidney injuries in older patients, the OttawaCitizen.com reports.

An article published on August 18th relays the results of research led by professionals at the Lawson Health Research Institute in London, Ont., and the Institute for Clinical Evaluative Sciences. Using Ontario health-care databases, the study’s leaders looked at 97,777 patients aged 65 and older who were prescribed Risperdal and other drugs between 2003 and 2011.

After following their health outcomes for 90 days, researchers found that 1,002 individuals taking this category of drug, which is used to treat schizophrenia, bipolar disorder and other conditions, were hospitalized for kidney problems. This included acute kidney injury, a sudden decrease in kidney function sustained by 10 percent of hospitalized patients. During the same 90-day period, it was also discovered that atypical antipsychotic users were prone to hospitalization pneumonia, heart attack, low blood pressure, ventricular arrhythmia and the inability to urinate.

The U.S. Food and Drug Administration (FDA) has warned in the past about the increased risk of death in older men treated with the medications. 6,666 users of Risperdal and other drugs died from all causes, the study found, compared to 2,985 who died after not taking the medications.

“That’s a lot of extra, additional deaths that may not have occurred,” said one of the study’s authors. He later described the rate of all-cause death as “a pretty robust signal. The warnings are out there and yet these drugs are still commonly prescribed.”

Risperdal Lawsuits Allege other Complications of Antipsychotic Drug

While not specifically noted in the Lawson Health Research Institute study, this statement could be applied to Risperdal lawsuits alleging other serious and debilitating injuries. Many of the plaintiffs involved in claims against the Johnson & Johnson medication allege complications associated with male breast development. Referred to as Risperdal gynecomastia, this complication may result in breasts as large as D cups, necessitating liposuction and mastectomy procedures to remove. More than 600 Risperdal lawsuits have now been centralized in a consolidated litigation underway in the Philadelphia Court of Common Pleas, court records indicate.
