Clinical Summary

An immunosuppressive agent used in combination with cyclophosphamide and hydroxychloroquine in the treatment of rheumatoid arthritis. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), this substance has been listed as a known carcinogen. (Merck Index, 11th ed)

Therapeutic Applications

Azathioprine is used to prevent organ rejection in people who have received a kidney transplant. It is usually taken along with other medications to allow your new kidney to function normally. Azathioprine is also used to treat rheumatoid arthritis. In this condition, the body's defense system (immune system) attacks healthy joints. Azathioprine belongs to a class of drugs known as immunosuppressants. It works by weakening the immune system to help your body accept the new kidney as if it were your own (in the case of an organ transplant) or to prevent further damage to your joints (in the case of rheumatoid arthritis). Talk to your doctor about the risks and benefits of azathioprine, especially when used by children and young adults.

Clinical Summary

A carbazole and propanol derivative that acts as a non-cardioselective beta blocker and vasodilator. It has blocking activity for ALPHA 1 ADRENERGIC RECEPTORS and, at higher doses, may function as a blocker of CALCIUM CHANNELS; it also has antioxidant properties. Carvedilol is used in the treatment of HYPERTENSION; ANGINA PECTORIS; and HEART FAILURE. It can also reduce the risk of death following MYOCARDIAL INFARCTION.

Therapeutic Applications

Carvedilol is used to treat high blood pressure and heart failure. It is also used after a heart attack to improve the chance of survival if your heart is not pumping well. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This drug works by blocking the action of certain natural substances in your body, such as epinephrine, on the heart and blood vessels. This effect lowers your heart rate, blood pressure, and strain on your heart. Carvedilol belongs to a class of drugs known as alpha and beta blockers.

Clinical Summary

An antilipemic agent which reduces both CHOLESTEROL and TRIGLYCERIDES in the blood.

Therapeutic Applications

Fenofibrate is used along with a proper diet to help lower bad cholesterol and fats (such as LDL, triglycerides) and raise good cholesterol (HDL) in the blood. It works by increasing the natural substance (enzyme) that breaks down fats in the blood. Fenofibrate belongs to a group of drugs known as fibrates. Lowering triglycerides in people with very high triglyceride blood levels may decrease the risk of pancreas disease (pancreatitis). However, fenofibrate might not lower your risk of a heart attack or stroke. Talk to your doctor about the risks and benefits of fenofibrate. In addition to eating a proper diet (such as a low-cholesterol/low-fat diet), other lifestyle changes that may help this medication work better include exercising, losing weight if overweight, and stopping smoking. Consult your doctor for more details.

Clinical Summary

Compound derived from Penicillium stoloniferum and related species. It blocks de novo biosynthesis of purine nucleotides by inhibition of the enzyme inosine monophosphate dehydrogenase (IMP DEHYDROGENASE). Mycophenolic acid exerts selective effects on the immune system in which it prevents the proliferation of T-CELLS, LYMPHOCYTES, and the formation of antibodies from B-CELLS. It may also inhibit recruitment of LEUKOCYTES to sites of INFLAMMATION.

Therapeutic Applications

Mycophenolate is used in combination with other medications to keep your body from attacking and rejecting your transplanted organ (such as kidney, liver, heart). It belongs to a class of medications called immunosuppressants. It works by weakening your body's defense system (immune system) to help your body accept the new organ as if it were your own.

Clinical Summary

A 4-methoxy-3,5-dimethylpyridyl, 5-methoxybenzimidazole derivative of timoprazole that is used in the therapy of STOMACH ULCERS and ZOLLINGER-ELLISON SYNDROME. The drug inhibits an H(+)-K(+)-EXCHANGING ATPASE which is found in GASTRIC PARIETAL CELLS.

Therapeutic Applications

Omeprazole is used to treat certain stomach and esophagus problems (such as acid reflux, ulcers). It works by decreasing the amount of acid your stomach makes. It relieves symptoms such as heartburn, difficulty swallowing, and cough. This medication helps heal acid damage to the stomach and esophagus, helps prevent ulcers, and may help prevent cancer of the esophagus. Omeprazole belongs to a class of drugs known as proton pump inhibitors (PPIs). If you are self-treating with this medication, over-the-counter omeprazole products are used to treat frequent heartburn (occurring 2 or more days a week). Since it may take 1 to 4 days to have full effect, these products do not relieve heartburn right away. For over-the-counter products, carefully read the package instructions to make sure the product is right for you. Check the ingredients on the label even if you have used the product before. The manufacturer may have changed the ingredients. Also, products with similar brand names may contain different ingredients meant for different purposes. Taking the wrong product could harm you.

Clinical Summary

A potassium sparing diuretic that acts by antagonism of aldosterone in the distal renal tubules. It is used mainly in the treatment of refractory edema in patients with congestive heart failure, nephrotic syndrome, or hepatic cirrhosis.

Evaluating the prescriptive footprints of clinical practitioners like MARINA G SILVEIRA M.D. provides transparency into local medical care patterns within New Haven, CT.

Key Learning Objectives for this Profile:

  • Prescribing Frequencies: Track and evaluate the volume metrics of specific brand-name and generic medical formulas chosen by this provider over time.
  • Clinical Focus Areas: Identify how the provider distributes therapeutic selections across medical care options to gain insight into their true day-to-day **Internal Medicine** practice concentrations.
