Editorial comments • Lomefloxacin is used for the same indications as ofloxacin but is more likely to produce phototoxicity. Warnings/precautions • Use with caution in patients with reduced bone marrow activ- ity and liver disease and in patients receiving other drugs that cause bone marrow suppression. Clinically important drug interactions • The following drug increases effects/toxicity of lomustine: cimetidine. Treat with peroxide, tea, topical anesthetics such as benzocaine and lidocaine or anti-fungal drug. Editorial comments • Cumulative bone marrow toxicity manifested by thrombocy- topenia is a major concern with lomustine. Mechanism of action: Binds to penicillin-binding proteins and disrupts or inhibits bacterial cell wall synthesis.

Docusate is commonly prescribed to prevent strain- ing during a bowel movement after surgery purchase hydrea 500 mg amex symptoms 5 days before your missed period. Multitalented The kidneys perform several vital tasks discount hydrea generic medicine games, including: • disposing of wastes and excess ions in the form of urine • filtering blood generic hydrea 500 mg overnight delivery treatment kidney cancer symptoms, which regulates its volume and chemical make- up • helping to maintain fluid best purchase for hydrea medications for high blood pressure, electrolyte, and acid-base balances • producing several hormones and enzymes • converting vitamin D to a more active form • helping to regulate blood pressure and volume by secreting renin. Thiazide and thiazide-like diuretics Derived from sulfonamides, thiazide and thiazide-like diuretics are used to treat edema and to prevent the development and recur- rence of renal calculi. They’re also used for such cardiovascular diseases as hypertension and heart failure. Thiazide diuretics include: • bendroflumethiazide • chlorothiazide • hydrochlorothiazide • hydroflumethiazide • methyclothiazide • polythiazide. These drugs differ in how well they’re me- tabolized, but all are excreted primarily in urine. Chlor- thalidone is 90% bound to erythrocytes; little is known about its metabolism. Pharmacodynamics (how drugs act) Thiazide and thiazide-like diuretics promote the excretion of wa- ter by preventing the reabsorption of sodium in the kidneys. These drugs also increase the excretion of chloride, potas- sium, and bicarbonate, which can result in electrolyte imbalances. With long-term use, thiazide diuretics also lower blood pressure by causing arteriolar vasodilation. However, if therapy is maintained, car- diac output stabilizes but plasma fluid volume decreases. Adverse Pharmacotherapeutics (how drugs are used) reactions to Thiazides are used for the long-term treatment of hypertension; thiazide and they’re also used to treat edema caused by kidney or liver disease, thiazide-like mild or moderate heart failure, and corticosteroid and estrogen diuretics therapy. Because these drugs decrease the level of calcium in urine, they may be used alone or with other drugs to prevent the The most common ad- development and recurrence of renal calculi. Drug interactions Drug interactions related to thiazide and thiazide-like diuretics re- sult in altered fluid volume, blood pressure, and serum electrolyte Administering levels: thiazide diuretics • These drugs may decrease excretion of lithium, causing lithium along with toxicity. They under- go partial or complete metabolism in the liver, except for furo- semide, which is excreted primarily unchanged. Bumetanide— tient who has an allergy which is 40 times more potent than furosemide—is the shortest- to sulfa may experience acting diuretic. Loop diuretics also have a high potential for caus- an allergic reaction to ing severe adverse reactions. Use with The scoop on the loop caution, and alert the patient to this possibility. Loop diuretics received their name because they act primarily on the thick, ascending loop of Henle (the part of the nephron re- sponsible for concentrating urine) to increase the secretion of sodium, chloride, and water. These drugs also inhibit sodium, chloride, and water reabsorption in the proximal tubule. Pharmacotherapeutics Loop diuretics are used to treat edema associated with renal dis- ease, hepatic cirrhosis, and heart failure, as well as to treat hyper- tension (usually with a potassium-sparing diuretic or potassium supplement to prevent hypokalemia). Ethacrynic acid may also be used for the short-term manage- ment of ascites due to malignancy, idiopathic edema, or lym- phedema. Drug interactions Loop diuretics produce a variety of drug interactions: • The risk of ototoxicity (damage to the organs of hearing) in- creases when aminoglycosides and cisplatin are taken with loop diuretics (especially with high doses of furosemide). Potassium-sparing diuretics Adverse Potassium-sparing diuretics have weaker diuretic and antihyper- reactions to tensive effects than other diuretics but provide the advantage of loop diuretics conserving potassium.
