TUESDAY, Nov. 15, 2016 (HealthDay Information) -- A preferred class of heartburn drugs -- together with Nexium, Prevacid, Prilosec and Protonix -- might enhance your danger of stroke, a brand new research suggests.

Often known as proton pump inhibitors (PPIs), these medication elevated individuals's general stroke danger by 21 p.c, mentioned research lead writer Dr. Thomas Sehested.

Nevertheless, the danger seems to be pushed by individuals who take excessive doses, added Sehested, analysis director on the Danish Coronary heart Basis in Copenhagen.

"Folks handled with a low dose of PPIs didn't have a excessive danger of stroke," he mentioned. "These handled with the very best doses of PPIs had the very best danger of stroke."

The extent of danger additionally depends upon the particular PPI taken.

On the highest dose, stroke danger ranged from 30 p.c for lansoprazole (Prevacid) to 94 p.c for pantoprazole (Protonix), the researchers mentioned.

Takeda Pharmaceutical, the maker of prescription-only Protonix, didn't reply to a request for remark.

PPIs particularly affected danger of the commonest kind of stroke, ischemic stroke, which happens when a clot blocks blood movement to the mind.

Proton pump inhibitors deal with heartburn by blocking acid-producing cells within the lining of the abdomen.

Prior research have related PPI use with coronary heart illness, coronary heart assaults and dementia, Sehested mentioned.

Nevertheless, due to its design, the brand new research cannot set up a direct cause-and-effect relationship between these heartburn medication and elevated stroke danger. The analysis solely exhibits an affiliation.

For this research, researchers analyzed the data of almost 245,000 Danish sufferers, common age 57. All had undergone an endoscopy, a process used to determine the causes of abdomen ache and indigestion.

Throughout about six years of follow-up, almost 9,500 sufferers had their first ischemic stroke.

Researchers checked to see if the stroke occurred whereas sufferers had been taking any of those PPIs: omeprazole (Prilosec), esomeprazole (Nexium), Prevacid or Protonix. The researchers additionally requested about one other class of antacids often called H2 blockers, which embody Pepcid and Zantac.

The analysis crew discovered elevated danger from PPIs, however none from H2 blockers. The connection held even after researchers adjusted for different danger elements for stroke and coronary heart illness, Sehested mentioned.

The outcomes had been scheduled for presentation Tuesday on the American Coronary heart Affiliation annual assembly, in New Orleans. The findings ought to be thought-about preliminary till peer-reviewed for publication in a medical journal.

Nobody is bound why PPIs might have a dangerous impact on coronary heart well being, Sehested mentioned. He famous that PPIs would possibly scale back ranges of biochemicals which are vital for the upkeep of blood vessels. With out these biochemicals, individuals may expertise hardening of the arteries, he theorized.

Most PPIs are actually obtainable over-the-counter, and docs are involved that persons are taking the medication after they should not, mentioned Dr. Philip Gorelick, medical director of the Mercy Well being Hauenstein Neuroscience Heart in Grand Rapids, Mich.

"Lots of people proceed to take these medicines for extended intervals of time, or use these drugs for indications which are suspect, or not accepted by the FDA," Gorelick mentioned. "So one must be cautious about that."

Utilizing the medication for a shorter interval or at decrease doses might show to be safer, he added.

Individuals who want PPIs and have been prescribed one by a physician ought to proceed utilizing them, Sehested mentioned.

Nevertheless, individuals who began utilizing a PPI and not using a physician's steerage, or stored utilizing one after the prescribed interval, ought to speak with their doctor about whether or not they need to minimize the medication out.

"Lots of people are utilizing these medication and not using a clear indication, similar to a transparent analysis exhibiting they need to use these medication day by day," Sehested mentioned. "They need to take into consideration quitting these medication."
