<p>Dihydrotachysterol is a synthetic analog of vitamin D, which is derived from ergocalciferol or cholecalciferol. It is a semi-synthetic compound tailored to mimic the active form of vitamin D, playing a crucial role in calcium metabolism. Unlike naturally occurring vitamin D, Dihydrotachysterol does not require metabolic activation in the kidneys, making it particularly useful in patients with impaired renal function.</p>
