A subsequent study, 17 however, demonstrated that torsemide does not bind the MR in rat cardiomyocytes. This suggests that the increase in serum aldosterone seen in the study by Hori and colleagues 15 is not entirely the result of MR blockade and likely represents RAAS activation from sodium depletion and diuresis.

Ames, DVM, Diplomate ACVIM (Cardiology) Colorado State University. This medicine causes a profound increase in urine output (diuresis) by preventing the TEENney from retaining water. Specifically, it blocks the reabsorption back into the blood of sodium and water that has been filtered out of the blood by the TEENneys. Torsemide is in a class of diuretic drugs called "loop" diuretics, which also includes the drugs furosemide ( Lasix ) and bumetanide (Bumex). Torsemide 10-20 mg is approximately equivalent to 1 mg of bumetanide and 40 mg of furosemide. The potent diuretic effect of torsemide can cause the loss of large amounts of body water leading to dehydration as well as the loss of electrolytes (for example, sodium, potassium, magnesium, and calcium). Therefore, careful medical supervision is necessary during treatment. What brand names are available for torsemide? Demadex is the brand name for this medication in the U.S. Is torsemide available as a generic drug? Yes, it's available as a generic drug. Do I need a prescription for torsemide?

Furosemide's rapid onset of action makes it indispensable in the emergent treatment of cardiogenic pulmonary edema. It does, however, have a relatively short duration of action, which often necessitates repeated bolus dosing in the emergency setting and, at home, up to 3 to 4 times per day dosing in patients with advanced CHF. This characteristic—multiple peaks and valleys in serum drug concentrations—may enhance furosemide's stimulation of the sympathetic nervous system and RAAS, contributing to diuretic resistance.7 Increasing dosages are required over time and, in many cases, other diuretics are added to maintain patient comfort. I therefore suggest that the myth that bumetanide is better absorbed in patients with oedema may be being perpetuated through the misguided belief in the bumetanide 1mg: furosemide 40mg dose equivalence when switching between these loop diuretics. nauseau, vomiting, TEENney failure, bleeding disorders, coma, and death. Acetaminophen is a drug contained in over 200 OTC and prescription medications from NyQuil to Vicodin. Avoiding unintentional overdoses include reading medication labels, write down the dosages of medications you are taking, do not drink excessive alcohol while taking acetaminophen. In severe cases, a liver transplant may be necessary. Re: How to prescribe loop diuretics in oedema.

Torsemide can cause low blood potassium, calcium, and magnesium levels. These changes can increase the risk of toxicity from digoxin (Lanoxin). Combining torsemide with other diuretics such as metolazone ( Zaroxolyn ), hydrochlorothiazide, or chlorthalidone (Hygroton) can exaggerate the losses of potassium and magnesium. The body's ability to eliminate lithium ( Lithobid, Eskalith) may decrease in patients receiving torsemide. Therefore, careful monitoring of lithium levels in blood is recommended when torsemide and lithium are taken together in order to prevent increases in lithium levels and lithium toxicity. When standard doses of diuretics become inadequate to maintain the patient's quality of life, several strategies can be used, such as increasing dosage, increasing frequency of administration, adding new drugs (ie, sequential nephron blockade with such agents as hydrochlorothiazide and spironolactone), or changing to another drug (eg, torsemide or bumetanide) to boost diuresis ( Figures 5 and 6 ).

At day 5 and 10, the RAAS is activated and, with continuous treatment, stays activated for at least 10 days. The urine A:Cr ratio indicates the amount of aldosterone found in the urine over 24 hours and reflects RAAS activation.

Take our Heart Disease Quiz to get answers and facts about high cholesterol, atherosclerosis prevention, and the causes,. Other antialdosterone and antifibrotic effects of torsemide are postulated, however, and warrant further study. 18-20 Regardless of whether there is an MR-blocking effect, it seems prudent to administer an ACE inhibitor or spironolactone with torsemide due to the very high plasma aldosterone concentrations associated with its use ( Figure 7 ). >/Rotate 0/StructParents 14/TrimBox[0 0 612 792]/Type/Page>> endobj 11 0 obj.

When is the transition to oral diuretic therapy made in the treatment of acute heart failure?. Indomethacin ( Indocin ) can reduce the diuretic and blood pressure -lowering effects of other loop diuretics (for example furosemide) and it probably can do the same with torsemide. Other nonsteroidal anti-inflammatory drugs -- for example, ibuprofen ( Motrin ) and naproxen ( Naprosyn ) -- may interact similarly. Concomitant use of torsemide and aminoglycosides may increase the risk of hearing impairment since both agents can affect hearing. Kajstura J, Leri A, Castaldo C, Nadal-Ginard B, Anversa P.

Which of the following assessment made by the nurse indicates a further immediate action? Primary (essential or idiopathic) hypertension: elevated BP without an identified cause; accounts for 90% to 95% of all cases of hypertension. Stress and increased SNS activity: Arterial pressure is influenced by factors such as anger, fear, and pain. Physiologic responses to stress, which are normally protective, may persist to a pathologic degree, resulting in prolonged increase in SNS activity. Increased SNS stimulation produces increased vasoconstriction, increased HR, and increased renin release. Contributing factors to the development of hypertension include cardiovascular risk factors combined with socioeconomic conditions and ethnic differences.
