A new study<\/a> out of Brazil evaluated the impact of prolonged use of proton pump inhibitors (PPIs), the technical term for this range of medicines \u2014\u00a0and what researchers found was stomach-churning.<\/p>\n The most common PPIs are known by the brand names Prilosec, Nexium and Prevacid, which are widely available and generally come with warnings about length of use.<\/p>\n In the case of Prilosec, also known as omeprazole, it\u2019s recommended not to exceed eight weeks of use and to discuss ongoing treatment with a doctor.\u00a0<\/p>\n But researchers report that \u201cchronic and unregulated consumption is frequently observed,\u201d prompting them to pursue this study.<\/p>\n After treating a group of rats with PPIs over 10-, 30- and 60-day periods, the researchers paid close attention to the bioavailability of certain vitamins and minerals in the blood and organs, including iron, calcium, magnesium, copper, zinc and potassium.\u00a0<\/p>\n Their analysis clearly showed the drug-treated rats had an impaired ability to absorb those nutrients. Among the greatest imbalances they observed were iron, copper and calcium levels \u2014 red flags for anemia and osteoporosis, with potential consequences like arrhythmia and chronic kidney disease.<\/p>\n This is likely due to the way PPIs were designed to work, and why they\u2019re so effective for short-term symptom management.<\/p>\n To combat the irritating creep of acid reflux as well as other concerns like ulcers and gastritis, the authors noted that PPIs increase the pH of stomach acids and reduce hydrogen, which limits the body\u2019s ability to absorb all the nutrients from what it\u2019s consuming.\u00a0<\/p>\n Stomach acidity plays an important role in not only absorbing nutrients, but keeping bad bacteria at bay. It\u2019s for this reason that PPIs have also been associated with gut issues like bacterial overgrowth in the small intestine.<\/p>\n But the researchers also emphasize that controlled use of these drugs likely won\u2019t lead to any big issues.<\/p>\n \u201cIt isn\u2019t a question of demonizing the drug, which is effective for various gastric conditions,\u201d said Andr\u00e9a Santana de Brito<\/a>, whose master\u2019s research involved this study. \u201cThe problem is its trivialized use, even for mild symptoms such as heartburn, and for prolonged periods of months and even years. Its adverse effects shouldn\u2019t be overlooked.\u201d\u00a0<\/p>\n Brazilian health authorities recently green-lit over-the-counter sales of a 14-day supply of 20 milligrams omeprazole. Santana de Brito fears this move might \u201cencourage self-medication and continuous use, disregarding the recommendation to limit treatment to 14 days.\u201d<\/p>\n The health agency has called it \u201ca step forward in rationalizing its use and promoting its safe and responsible use.\u201d<\/p>\n \u201cBy limiting treatment to a maximum of 14 days, the message that the drug should only be used to relieve mild and temporary symptoms is reinforced, encouraging patients to seek a medical evaluation if their symptoms persist or recur,\u201d the agency added.<\/p>\n Similar dosage is available over the counter<\/a> throughout the US.
