Heartburn Health Article

Drugs

Occasional heartburn is commonly treated with nonprescription antacids that neutralize the pH of stomach acid. The neutralized acid does not burn the esophagus. Antacids usually work within 15 minutes and their effects last one to two hours. Liquid or dissolving antacids usually act faster than tablets. However, antacids, if taken for too long, can cause side effects, including diarrhea or constipation.

Some antacids interfere with medications for kidney or heart disease. Heartburn sufferers with two or more episodes per week, or with an episode lasting more three weeks, should not rely on antacids as the sole treatment, since they may be at risk of kidney damage or other metabolic changes.

Common antacids include Maalox, Mylanta, Alka-Seltzer, Pepto-Bismol, Riopan, and Rolaids. The active ingredient in antacids such as Tums is calcium carbonate. Alginate (Gaviscon) is a foaming agent that coats the esophagus and the stomach to help prevent reflux. Other antacids are made from aluminum hydroxide, magaldrate, or magnesium hydroxide. Some antacids contain baking soda (sodium bicarbonate), which may interfere with vitamin and mineral absorption during pregnancy.

Histamine receptor (H2) blockers, such as famotidine (Pepcid), ranitidine (Zantac), nizatidine (Axid), and cimetidine (Tagamet), decrease stomach acid secretion. They relieve heartburn in about 75% of users. However, they take 30 to 45 minutes to act and usually are taken two to four times daily for several weeks. H2 blockers are both over-the-counter (OTC) and prescription medicines. They may have side effects or interactions with other medications.

Proton pump inhibitors (PPI) are for severe heartburn. They are the most effective drugs for inhibiting acid production and allowing the esophagus to heal in GERD. It may take up to five days for PPIs to take effect. They cannot be used by people with kidney or liver problems. Although it appears safe to take PPIs for at least 10 years, the lowest effective dosage reduces the risk of side effects that may include headache, diarrhea, stomach pain, and interactions with other medications. Common PPIs include lansoprazole (Prevacid), omeprazole (Prilosec), rabeprazole (Aciphex), pantoprazole (Protonix), and esomeprazole (Nexium). Prilosec OTC is available in 20-milligram doses to be taken once a day for 14 days to treat frequent heartburn.

Prokinetics are drugs that strengthen the LES (lower esophageal sphincter) and increase the rate of stomach emptying. These include metoclopramide (Reglan) and bethanechol (Urecholine). These drugs frequently have side effects.

Surgery

Laparoscopic Nissen fundoplication is a surgical procedure to increase pressure on the LES by stretching and wrapping the upper part of the stomach around it. It is performed under general anesthetic and takes one to two hours. The complete recovery period is less than two weeks.

GERD (gastroesophageal reflux disease) may be treated successfully by endoscopic suturing of the weakened LES to stop acid reflux. Studies have shown that symptoms usually improve with this procedure and the use of medications declines. Another procedure involves using electrodes to make tiny cuts in the LES tissues. The resulting scarring tightens the LES. These outpatient procedures take less than an hour. They are not used in cases of hiatal hernia or Barrett's esophagus.

If the esophagus has become narrowed and badly scarred from stomach acid, a procedure that stretches and widens the esophageal tissue may be used along with acid-suppressing medication. Enteryx is a liquid that can be injected into the LES where it forms a spongy muscle implant that strengthens the LES.

Prognosis

Occasional heartburn without esophageal damage has an excellent prognosis. Esophageal damage that is treated with a program that promotes healing also has an excellent prognosis. Infants usually outgrow gastroesophageal reflux by age one.

Untreated heartburn and GERD may lead to bleeding, esophageal ulcers, and infections. With treatment, the damaged tissue that forms ulcers can heal. About ten percent of patients with GERD experience esophageal narrowing from acid damage that leads to the formation of scar tissue in the lower esophagus. GERD also can cause laryngitis, bronchitis, and aspiration pneumonia. After five years of heartburn, the risk of developing Barrett's esophagus increases. About five percent of GERD patients have Barrett's syndrome. This condition is incurable and may lead to cancer. The prognosis for esophageal cancer is very poor. There is a strong likelihood of painful illness and a less than five percent chance of survival for more than five years.
