Disease-modifying antirheumatic drugs (DMARDs)
are used for initial treatment of rheumatoid arthritis
(RA) to achieve clinical remission and prevent
irreversible joint damage (see Table 1). DMARDs
generally do not have an immediate analgesic effect,
but over time they can control symptoms and have
been shown to delay and possibly stop progression
of the disease. Methotrexate (Trexall, and others)
is generally the drug of choice; it can be used for
patients with low, moderate, or high disease activity.
For mild disease, some clinicians prefer to start with
hydroxychloroquine (Plaquenil, and generics) and/or
sulfasalazine (Azulfidine, and others).

Aminosalicylates are effective for induction and maintenance
of remission in mild to moderate ulcerative
colitis. They are not recommended for treatment of
Crohn's disease.
FORMULATIONS — Oral mesalamine is rapidly absorbed in the small intestine and most of the drug does not reach the colon. Pentasa releases mesalamine gradually throughout the gastrointestinal tract. Delzicol, Asacol HD, Lialda, and Apriso delay the release of the drug until it reaches the distal ileum and colon. Sulfasalazine (Azulfidine, and generics), balsalazide (Colazal, and others), and olsalazine (Dipentum) are prodrugs; mesalamine is azo-bonded to a second moiety and released in the colon following bacterial cleavage of the bond. Mesalamine is also available as an enema (Rowasa, and generics) and as a rectal suppository (Canasa).

HMG-CoA reductase inhibitors (statins) inhibit
the enzyme that catalyzes the rate-limiting step in
cholesterol synthesis. The subsequent reduction in
hepatic cholesterol leads to increased expression of
LDL receptors, which in turn increases uptake and
clearance of LDL-C from the blood. Statins also lower
very low-density lipoprotein cholesterol (VLDL-C)
and triglycerides. Most statins increase high-density
lipoprotein cholesterol (HDL-C), but only modestly.

Disease-modifying anti-rheumatic drugs (DMARDs)
are now used early in the treatment of rheumatoid
arthritis (RA) to achieve clinical remission, prevent
irreversible damage to joints, and minimize toxicity
associated with nonsteroidal anti-inflammatory drugs
(NSAIDs) and corticosteroids. DMARDs (Table 1)
generally do not have an immediate analgesic effect,
but over time can control symptoms and have been
shown to delay and possibly stop progression of the
disease. NSAIDs have immediate analgesic and antiinflammatory
effects, but may not affect the disease
process. Oral corticosteroids can relieve joint symptoms
and control systemic manifestations, but their
chronic use can cause many complications. Judicious
use of intra-articular corticosteroids can rapidly
decrease inflammation in acute joints with few, if any,
adverse effects.

Allergic rhinitis, allergic conjunctivitis, atopic dermatitis, urticaria, anaphylaxis and asthma (not included here; reviewed in Treatment Guidelines 2008; 6:83) 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 these allergic diseases, patients should be instructed to avoid, if possible, specific allergens and/or environmental conditions that trigger or worsen their symptoms. Allergen-specific immunotherapy may be useful for treatment of allergic rhinitis and allergic conjunctivitis, and in preventing severe insect venom-triggered reactions.

The FDA has approved the marketing of fenofibric acid (Trilipix - Abbott) to reduce triglycerides and increase HDL-C in patients with mixed dyslipidemia on optimal doses of a HMG-CoA reductase inhibitor (statin) who have, or have risk factors for, coronary heart disease. It is the first fibrate approved by the FDA specifically for combined use with a statin. Trilipix is also approved as monotherapy for hypertriglyceridemia, hypercholesterolemia and low HDL-C. The patent for Tricor, Abbott's older formulation of fenofibrate, will expire in 2011.

A recent letter to the editor of the Annals of Internal Medicine documented a single case of myopathy apparently due to an interaction between simvastatin (Zocor, and others) and green tea. Since it became available generically, simvastatin has surpassed atorvastatin (Lipitor) as the best selling statin. As such, it is probably the most common cause of statin-induced myopathy, which is often a result of drug interactions.

Drugs that lower low-density lipoprotein cholesterol (LDL-C) concentrations can prevent formation, slow progression and cause regression of atherosclerotic lesions. They should not be used as a substitute for lifestyle changes; a combination of diet, exercise and lipid-lowering drugs is optimal for prevention of coronary disease. Lipid-regulating drugs must be taken indefinitely; when they are stopped, plasma lipoprotein levels return to pretreatment levels in 2-3 weeks.

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.

Many different drugs are now used to treat rheumatoid arthritis. Nonsteroidal anti-inflammatory drugs (NSAIDs), listed in the table on page 26, have analgesic and anti-inflammatory effects, but may not affect the disease process. Corticosteroids can provide rapid relief of joint symptoms and control of systemic manifestations, but chronic use is associated with many complications. The "disease-modifying" anti-rheumatic drugs (DMARDs), listed on page 29, have no immediate analgesic effects, but can control symptoms and may delay progression of the disease (American College of Rheumatology Subcommittee on Rheumatoid Arthritis Guidelines, Arthritis Rheum 2002; 46:328). Interactions of anti-rheumatic drugs with other drugs are listed in The Medical Letter Handbook of Adverse Drug Interactions, 2003.

Lowering elevated serum cholesterol concentrations can slow progression and sometimes cause regression of atherosclerotic lesions. Most authorities advise patients with high cholesterol concentrations to eat less fat and less cholesterol and, when appropriate, to lose weight. If these measures do not lower serum lipids sufficiently, drugs are frequently added to the regimen. When drugs are discontinued, serum cholesterol concentrations generally return to pretreatment levels.

Intensive chemotherapy, with or without total body radiation, followed by bone marrow transplantation is now widely used in the treatment of malignant diseases. The drugs and radiation needed to try to eradicate the malignancy unavoidably destroy the bone marrow; intravenous infusion of bone marrow cells restores the marrow by repopulating it. Diseases for which bone marrow transplantation has been used include the leukemias and lymphomas, breast cancer, neuroblastoma, ovarian cancer, germ cell tumors, melanoma, multiple myeloma, and malignant gliomas (NC Gorin, Am J Clin On-col, 14 suppl 1:S5, 1991; Medical Letter, 33:39, 1991; G Gahrton et al, N Engl J Med, 325:1267, 1991).

The incidence of opportunistic fungal infections continues to increase, particularly in patients who have AIDS, are taking immunosuppressive drugs, or are in intensive care units. Intravenous (IV) amphotericin B (Fungizone, and others), sometimes given with flucytosine (Ancobon), is the drug of choice for initial treatment of most rapidly progressive, acutely life-threatening fungal infections; for less severe infections, fluconazole (Diflucan, ketoconazole (Nizoral), or itraconazole (Sporanox - an investigational drug in the (USA) may also be effective, can be taken orally, and are much better tolerated. The treatment of superficial fungal infections is not discussed here.

Recent reports indicate that lowering elevated serum cholesterol concentrations not only decreases mortality from coronary artery disease, but may cause regression of atherosclerotic lesions (JP Kane et al, JAMA, 264:3007, Dec 19, 1990). Most authorities advise patients with high cholesterol concentrations to eat less saturated and total fat and lose weight. If these measures do not lower serum lipids, drugs are frequently added to the regimen. When drugs are discontinued, serum cholesterol concentrations generally return to pretreatment levels.

The recent surge of interest in lowering serum cholesterol concentrations has led to vigorous promotion of various hypocholesterolemic drugs in the USA. Since the risk of coronary heart disease is increased in patients with high serum cholesterol concentrations, most authorities advise such patients to eat less fat and try to lose weight (The Expert Panel, Arch Intern Med, 148:36, 1988). When these measures fail, cholesterol-lowering drugs are frequently recommended.
