Midamor Actions |
||
Midamor works by inhibiting sodium reabsorption in the distal convoluted tubules and collecting ducts in the kidneys by binding to the Midamor-sensitive sodium channels. This promotes the loss of sodium and water from the body, but without depleting potassium. Midamor exerts its potassium sparing effect through the inhibition of sodium reabsorption at the distal convoluted tubule, cortical collecting tubule and collecting duct; this decreases the net negative potential of the tubular lumen and reduces both potassium and hydrogen secretion and their subsequent excretion. Midamor is not an aldosterone antagonist and its effects are seen even in the absence of aldosterone.
In addition to the use of Midamor, treatment for your high blood pressure may include weight control and changes in the types of foods you eat, especially foods high in sodium. Your doctor will tell you which of these are most important for you. You should check with your doctor before changing your diet.
Many patients who have high blood pressure will not notice any signs of the problem. In fact, many may feel normal. It is very important that you take your medicine exactly as directed and that you keep your appointments with your doctor even if you feel well.
Remember that Midamor will not cure your high blood pressure, but it does help control it. You must continue to take it as directed if you expect to lower your blood pressure and keep it down. You may have to take high blood pressure medicine for the rest of your life. If high blood pressure is not treated, it can cause serious problems such as heart failure, blood vessel disease, stroke, or kidney disease.
It is best to take Midamor with food.
The dose of Midamor will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of Midamor. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
If you miss a dose of Midamor, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

To be sure this medication is not causing harmful effects, your blood will need to be tested on a regular basis. Your kidney function may also need to be tested. It is important that you not miss any scheduled visits to your doctor.
Midamor can interfere with the results of a glucose tolerance test. Stop using this medication for at least 3 days before you have this test. Tell any doctor who treats you that you are using Midamor.
Store this medication at room temperature away from heat, light, and moisture. Do not allow the tablets to freeze.
MIDAMOR (Midamor) is a potassium-conserving (antikaliuretic) drug that possesses weak (compared with thiazide diuretics) natriuretic, diuretic, and antihypertensive activity. These effects have been partially additive to the effects of thiazide diuretics in some clinical studies. When administered with a thiazide or loop diuretic, MIDAMOR (Midamor) has been shown to decrease the enhanced urinary excretion of magnesium which occurs when a thiazide or loop diuretic is used alone. MIDAMOR (Midamor) has potassium-conserving activity in patients receiving kaliuretic-diuretic agents.
MIDAMOR (Midamor) is not an aldosterone antagonist and its effects are seen even in the absence of aldosterone.
MIDAMOR (Midamor) exerts its potassium sparing effect through the inhibition of sodium reabsorption at the distal convoluted tubule, cortical collecting tubule and collecting duct; this decreases the net negative potential of the tubular lumen and reduces both potassium and hydrogen secretion and their subsequent excretion. This mechanism accounts in large proof for the potassium sparing action of Midamor.
MIDAMOR (Midamor) usually begins to act within 2 hours after an oral dose. Its effect on electrolyte excretion reaches a peak between 6 and 10 hours and lasts about 24 hours. Peak plasma levels are obtained in 3 to 4 hours and the plasma half-life varies from 6 to 9 hours. Effects on electrolytes increase with single doses of Midamor up to approximately 15 mg.
Midamor HCI is not metabolized by the liver but is excreted unchanged by the kidneys. About 50 percent of a 20 mg dose of MIDAMOR (Midamor) is excreted in the urine and 40 percent in the stool within 72 hours. MIDAMOR (Midamor) has little effect on glomerular filtration rate or renal blood flow. Because Midamor is not metabolized by the liver, drug accumulation is not anticipated in patients with hepatic dysfunction, but accumulation can occur if the hepatorenal syndrome develops.
