Clinical Anatomy For Dummies. The meninges are the coverings of the brain. They protect the brain by housing a fluid-filled space, and they function as a framework for blood vessels. The meninges have three layers: the dura mater, the arachnoid mater, and the pia mater. The arachnoid mater is attached to the pia mater by arachnoid trabeculae, which is a weblike matrix of connective tissue. The space between the two layers, the subarachnoid space, is filled with cerebrospinal fluid (CSF).
Potassium-sparing diuretics cause the kidneys to hold potassium in the body. When you are taking these medications you generally should not take potassium supplements because your potassium levels might rise too high. Treatments that combine thiazide diuretics (which cause potassium loss) and potassium-sparing diuretics can affect potassium levels unpredictably. If you are taking such a combination medication, do not take potassium except on the advice of your physician.
Not all diuretics cause this problem. The potassium-sparing diuretics don't lower potassium levels. These include spironolactone (Aldactone), eplerenone (Inspra) and triamterene (Dyrenium). In addition, some medications to treat high blood pressure may actually increase potassium levels in your blood. Among these are angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs) and renin inhibitors. Treatment of low potassium may include: Increasing potassium in your diet.
