Shelton and Rajfer (2012) noted that androgen deficiency in aging men is common, and the potential sequelae are numerous.  In addition to low libido, erectile dysfunction, decreased bone density, depressed mood, and decline in cognition, studies suggest strong correlations between low testosterone, obesity, and the metabolic syndrome.  Because causation and its directionality remain uncertain, the functional and cardiovascular risks associated with androgen deficiency have led to intense investigation of testosterone replacement therapy in older men.  Although promising, evidence for definitive benefit or detriment is not conclusive, and treatment of LOH is complicated.

Prednisone is a drug that belongs to the corticosteroid drug class, and is an anti-inflammatory and immune system suppressant. It's used to treat a variety of diseases and conditions, for example: inflammatory bowel disease (Crohn's disease and ulcerative colitis), lupus, asthma, cancers, and several types of arthritis.

Common side effects are weight gain, headache, fluid retention, and muscle weakness. Other effects and adverse events include glaucoma, cataracts, obesity, facial hair growth, moon face, and growth retardation in children. This medicine also causes psychiatric problems, for example: depression, insomnia, mood swings, personality changes, and psychotic behavior. Serious side effects include reactions to diabetes drugs, infections, and necrosis of the hips and joints.

Corticosteroids like prednisone, have many drug interactions; examples include: estrogens, phenytoin (Dilantin), diuretics, warfarin (Coumadin, Jantoven), and diabetes drugs. Prednisone is available as tablets of 1, , 10, 20, and 50 mg; extended release tablets of 1, 2, and 5mg; and oral solution of 5mg/5ml. It's use during the first trimester of pregnancy may cause cleft palate. This medicine is secreted in breast milk and can cause side effects in infants who are nursing. You should not stop taking prednisone abruptly because it can cause withdrawal symptoms and adrenal failure. Talk with your doctor, pharmacist, or other medical professional if you have questions about beta-blockers. Talk with your doctor, pharmacist, or other medical professional if you have questions about prednisone.

If you notice other effects not listed above, contact your doctor or pharmacist. In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.

The hypoglycemic action of glyburide is due to stimulation of pancreatic islet cells, which results in an increase in insulin secretion. Sulfonylureas are believed to bind to ATP-sensitive potassium-channel receptors on the pancreatic cell surface, thereby reducing potassium conductance and causing depolarization of the membrane. Depolarization stimulates calcium ion influx through voltage-sensitive calcium channels, raising intracellular concentrations of calcium ions, which induces the secretion, or exocytosis, of insulin. The drug is not effective in the absence of functioning beta-cells, as occurs in diabetes mellitus type 1, or when the number of viable beta-cells is low, as occurs in severe cases of diabetes mellitus type 2.
 
Prolonged administration of glyburide also produces extrapancreatic effects that contribute to its hypoglycemic activity. These effects include reduction of basal hepatic glucose production and an enhanced peripheral sensitivity to insulin secondary to an increase in insulin receptors or to changes in the events that follow insulin-receptor binding. The relative importance of each of these actions to the overall therapeutic effect of the drug will vary among oral antidiabetic agents and from patient to patient, which may account for the variability in potency among these drugs. Like glipizide, glyburide exhibits mild diuretic actions but does not affect uric acid concentrations.
