H2-RECEPTOR ANTAGONISTS (H2RAs) —
Currently available H2RAs are listed in Table 1.
These drugs inhibit the action of histamine at the H2-receptor of the gastric parietal cell, decreasing basal
acid secretion and, to a lesser degree, food-stimulated
acid secretion. All H2RAs are about equally effective
for treatment of PUD and GERD. H2RAs are faster
acting than PPIs in relieving symptoms of dyspepsia or
GERD, but they are not as effective as PPIs in relieving
symptoms or in healing erosive esophagitis. Repeated
administration of H2RAs leads to pharmacologic tolerance
and has been associated with the development
of new dyspeptic symptoms. Rebound acid hypersecretion
can occur after stopping H2RAs.

Drugs for Peptic Ulcer Disease and GERD

Peptic ulcer disease (PUD) is usually caused by nonsteroidal
anti-inflammatory drugs (NSAIDs) or by
infection with Helicobacter pylori. Gastroesophageal
reflux disease (GERD) can be caused by transient
lower esophageal sphincter relaxation, reduced lower
esophageal sphincter tone, hiatal hernia, delayed gastric
emptying or hormonal changes due to pregnancy.
Acid suppressive therapy is the cornerstone of management
for both PUD and GERD.

Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) are common causes of peptic ulcer disease. Patients infected with Helicobacter pylori who take aspirin or another NSAID have an especially high risk. Drugs that have been tried for prevention of ulcers in patients taking NSAIDs including H2-receptor antagonists, proton pump inhibitors (PPIs), aluminum- or magnesium-containing antacids, the prostaglandin misoprostol (Cytotec, and others), and antibiotics to eradicate H. pylori.

PPI Interactions with Clopidogrel Revisted

Current guidelines recommend use of a proton pump inhibitor (PPI) to decrease the risk of gastrointestinal bleeding in patients taking clopidogrel (Plavix) with aspirin. A recent issue of The Medical Letter considered whether omeprazole (Prilosec, and others) or other PPIs could interfere with the antiplatelet effect of clopidogrel. The conclusion was that patients taking both drugs should probably continue to do so until more data became available. Several new publications require reconsideration of that recommendation.

Peptic ulcers caused by treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) are mainly gastric ulcers. Most duodenal and other gastric ulcers are caused by the gram-negative bacillus Helicobacter pylori. Gastroesophageal reflux disease (GERD) is caused by gastric acid reflux into the esophagus. Drugs that suppress gastric acid production are the primary treatment for GERD and peptic ulcers.

Allergic rhinitis, allergic conjunctivitis, atopic dermatitis, urticaria, anaphylaxis and asthma (reviewed in Treatment Guidelines 2005; 3:33 and not included here), are prevalent worldwide, especially in industrialized countries. Pharmacologic treatment of these disorders continues to improve in efficacy and safety. In addition to using drugs to prevent and control the symptoms of their allergic diseases, patients should also be instructed to avoid, if possible, specific allergens and/or environmental conditions that trigger or worsen their symptoms.

Most peptic ulcers not caused by nonsteroidal anti-inflammatory drugs (NSAIDs) are associated with infection of the gastric mucosa by the gram-negative bacilli Helicobacter pylori. The majority of NSAID-related ulcers are gastric. H. pylori infection causes both duodenal and gastric ulcers. Eradication of H. pylori promotes healing and markedly decreases recurrence of both duodenal and gastric ulcers (A Shiotamni and DY Graham, Med Clin North Am 2002; 86:1447; FKL Chan and WK Leung, Lancet 2002; 360:933). The first step in the management of peptic ulcers is the diagnosis and treatment of H. pylori.

Zolmitriptan (Zomig - AstraZeneca) nasal spray was recently approved by the FDA for treatment of migraine. It is the second selective serotonin receptor agonist ("triptan") to become available as a nasal spray; sumatriptan has been available in this form since 1997. Some patients with migraine cannot take tablets because of nausea and vomiting, and nasal sprays are more convenient than subcutaneous injections.
Drugs for Allergic Disorders

Allergic rhinitis, allergic conjunctivitis, atopic dermatitis, urticaria and anaphylaxis, along with asthma (reviewed in Treatment Guidelines 2002; 1:7 and not included here), have increased in prevalence during the past 30 years and are now epidemic worldwide, especially in industrialized countries. Many safe and effective drugs are currently available for prevention and relief of symptoms in these disorders, but pharmacological treatment alone may not be sufficient. Patients should also be instructed to avoid specific allergens or environmental conditions that trigger their symptoms. Allergen-specific immunotherapy, parenteral administration of gradually increasing doses of the allergen ("allergy shots"), has been effective in allergic rhinitis, allergic conjunctivitis and allergic asthma, and also in prevention of anaphylaxis triggered by stings from bees, yellow jackets, hornets and wasps. It has not been effective in food allergy, atopic dermatitis or urticaria.

Older patients are especially susceptible to drug-induced cognitive impairment. They are more likely to be taking multiple drugs, to have higher blood levels of those drugs because of renal or hepatic dysfunction, and to have pre-existing cognitive problems that make it difficult to detect the role of drugs causing new symptoms or making old ones worse.

Metformin (Glucophage - Bristol-Myers Squibb), a hypoglycemic agent, was recently marketed in the USA for oral treatment of patients with non-insulin-dependent diabetes mellitus (NIDDM) not adequately controlled by diet alone. Previously marketed in more than ninety countries, including Canada, metformin (dimethylbiguanide) is chemically related to phenformin (phenylethylbiguanide), which was withdrawn from the US market in 1976 because it caused a high incidence of lactic acidosis. In approving metformin, the US Food and Drug Administration stipulated that a post-marketing controlled trial of 10,000 patients be conducted to determine the incidence of lactic acidosis.

Methadone, an opioid agonist that can be taken orally, has been used for maintenance treatment for many years in the USA (DM Novick et al, Drug Alcohol Depend, 33:235, 1993). Last year, the US Food and Drug Administration approved the distribution and use of L-alpha-acetyl-methadol (LAAM; ORLAAM - Bio Development Corporation, McLean, VA), a long-acting congener of methadone.

Paclitaxel (Taxol - Bristol-Myers Squibb) is now available in the USA for treatment of metastatic ovarian cancer refractory to other drugs. The new drug is a natural product extracted in small amounts from the inner bark of the Western yew tree found mainly in the Pacific northwest (Taxus brevifolia). Efforts to synthesize the drug have been unsuccessful to date, but a semi-synthetic product (taxotere) prepared from the needles of European yews has shown some promise (R Pazdur et al, J Natl Cancer Inst, 89:1781, 1992), and a fungus (Taxomyces andreanae) growing on the Pacific yew was recently found to produce paclitaxel even after removal from the tree (A Stierle et al, Science, 260:214, April 9, 1993). In any case, supply of the drug is currently keeping up with demand.
