Serum sodium (Florinef 0.1mg works by causing the kidneys to retain sodium in women after menopause) is usually maintained within the normal range of 135-145 mmol/1. Hyponatremia is defined as a reduction in the concentration of sodium in the aqueous portion of the serum. A reduction in serum sodium (Canadian Voltarol is one of a group of medicines called non-steroidal anti-inflammatory drugs) below 130 mmol/1 should be considered clinically significant. Hyponatremia is one of the most common electrolyte disorders in the elderly, and female gender is an important risk factor for the development of severe complications.

Water Metabolism
Water, comprising 55-65% of healthy adults, is the predominant constituent of the human body. This percentage diminishes proportionally with age, as the ratio of muscle to water-poor tissues, such as fat and bone, falls. Between 55% and 75% of water is contained within the intracellular compartment. Serum constitutes approximately one-fourth of the extracellular space, and antidiuretic hormone (ADH)—a nonapeptide produced by the neurohypophysis—closely regulates the water content within this compartment. Although multiple variables influence the secretion of ADH under normal physiologic conditions, the most important modulator of ADH secretion is the serum osmolality.

INTRODUCTION
With advancing age, the kidney undergoes several anatomical and physiological changes that limit the adaptive mechanisms responsible for maintaining the composition and volume of the extracellular fluid. These include a decline in glomerular filtration rate (GFR) and an impaired ability to maintain water and sodium (Generic Depakote used in the UK and U.S. for the treatment of the manic episodes of bipolar disorder) homeostasis in response to dietary and environmental changes. Consequently, elderly patients become more susceptible to clinical complications involving salt and water abnormalities.
