It is the active ingredient in the over the counter medication Aleve. Naproxen can be used for arthritis, tendinitis, bursitis, and menstrual cramps, to name a few. It is an effective over the counter medication, but has many side effects and contraindications.
Other physical characteristics that can apply to urine include colour, turbidity (transparency), smell (odour), pH (acidity-alkalinity), and density. Colour: Typically yellow-amber but varies according to recent diet and the concentration of the urine.
Urine is formed by nephrons, the functional unit of the kidney, and then flows through a system of converging tubules called collecting ducts. The collecting ducts join together to form minor calyces, then major calyces, which ultimately join the pelvis of the kidney (renal pelvis).
