Clinical Summary

A XANTHINE OXIDASE inhibitor that decreases URIC ACID production. It also acts as an antimetabolite on some simpler organisms.

Therapeutic Applications

Allopurinol is used to treat gout and certain types of kidney stones. It is also used to prevent increased uric acid levels in patients receiving cancer chemotherapy. These patients can have increased uric acid levels due to release of uric acid from the dying cancer cells. Allopurinol works by reducing the amount of uric acid made by the body.

Clinical Summary

A long-acting dihydropyridine calcium channel blocker. It is effective in the treatment of ANGINA PECTORIS and HYPERTENSION.

Therapeutic Applications

Amlodipine is used with or without other medications to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Amlodipine belongs to a class of drugs known as calcium channel blockers. It works by relaxing blood vessels so blood can flow more easily. Amlodipine is also used to prevent certain types of chest pain (angina). It may help to increase your ability to exercise and decrease the frequency of angina attacks. It should not be used to treat attacks of chest pain when they occur. Use other medications (such as sublingual nitroglycerin) to relieve attacks of chest pain as directed by your doctor.

Clinical Summary

A pyrrole and heptanoic acid derivative, HYDROXYMETHYLGLUTARYL-COA REDUCTASE INHIBITOR (statin), and ANTICHOLESTEREMIC AGENT that is used to reduce serum levels of LDL-CHOLESTEROL; APOLIPOPROTEIN B; and TRIGLYCERIDES. It is used to increase serum levels of HDL-CHOLESTEROL in the treatment of HYPERLIPIDEMIAS, and for the prevention of CARDIOVASCULAR DISEASES in patients with multiple risk factors.

Therapeutic Applications

Atorvastatin 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 belongs to a group of drugs known as statins. It works by reducing the amount of cholesterol made by the liver. Lowering bad cholesterol and triglycerides and raising good cholesterol decreases the risk of heart disease and helps prevent strokes and heart attacks. 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.

Clinical Summary

The physiologically active form of vitamin D. It is formed primarily in the kidney by enzymatic hydroxylation of 25-hydroxycholecalciferol (CALCIFEDIOL). Its production is stimulated by low blood calcium levels and parathyroid hormone. Calcitriol increases intestinal absorption of calcium and phosphorus, and in concert with parathyroid hormone increases bone resorption.

Therapeutic Applications

Calcitriol is a man-made active form of vitamin D. Most people get enough vitamin D from exposure to the sun and from fortified food products (such as dairy products, vitamins). Vitamin D helps control parathyroid hormone and the levels of certain minerals (such as calcium, phosphorus) that are needed for building and keeping strong bones. Before regular vitamin D can be used by the body, it needs to be changed to the active form by the liver and kidneys. Calcitriol is used in patients with kidney disease who can't make enough of the active form of Vitamin D. This medication is also used to prevent and treat certain types of calcium/phosphorus/parathyroid problems that can happen with long-term kidney dialysis or hypoparathyroidism. Calcitriol is usually used along with specific diet recommendations and sometimes other medications.

State Avg Cost Per Claim

$115.97

Note on Expenses: These indicators represent gross infrastructure resource tracking paid directly to supply pharmacy networks by Medicare Part D configurations. These calculations do not track individual patient insurance tier copays or out-of-pocket shelf prices at retail checkout lanes.

Therapeutic Applications

Calcium acetate is used to prevent high blood phosphate levels in patients who are on dialysis due to severe kidney disease. Dialysis removes some phosphate from your blood, but it is difficult to remove enough to keep your phosphate levels balanced. Decreasing blood phosphate levels can help keep your bones strong, prevent unsafe buildup of minerals in your body, and possibly decrease the risk of heart disease and strokes that can result from high phosphate levels. Calcium acetate is a natural mineral that works by holding onto phosphate from the diet so that it can pass out of your body.

Note on Expenses: These indicators represent gross infrastructure resource tracking paid directly to supply pharmacy networks by Medicare Part D configurations. These calculations do not track individual patient insurance tier copays or out-of-pocket shelf prices at retail checkout lanes.

Therapeutic Applications

Sucroferric oxyhydroxide is used to lower high blood phosphate levels in people who are on dialysis due to severe kidney disease.

Decreasing blood phosphate levels can help keep your bones strong, prevent unsafe buildup of minerals in your body, and may decrease the risk of heart disease and strokes that can result from high phosphate levels. Sucroferric oxyhydroxide contains a form of iron which is not absorbed by your body. It works by binding to phosphate in your diet. The phosphate then passes out of your body in your stool.
