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.

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.

Clinical Summary

The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in the THYROGLOBULIN. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.

Therapeutic Applications

Levothyroxine is used to treat an underactive thyroid (hypothyroidism). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery. Having enough thyroid hormone is important for maintaining normal mental and physical activity. In children, having enough thyroid hormone is important for normal mental and physical development. This medication is also used to treat other types of thyroid disorders (such as thyroid cancer). This medication should not be used to treat infertility unless it is caused by low thyroid hormone levels.
