One-Alpha⁚ A Vitamin D Analogue for Calcium and Bone Health
What is One-Alpha?
One-Alpha is a brand name for the drug alfacalcidol‚ a synthetic analogue of vitamin D․ It belongs to a group of medications known as vitamin D analogues and plays a crucial role in calcium homeostasis and bone metabolism․
One-Alpha is available in various forms‚ including⁚
- Capsules⁚ Available in different strengths (0․25 mcg‚ 0․5 mcg‚ 1 mcg) for oral administration․
- Oral drops⁚ A liquid form for those who have difficulty swallowing capsules․

What is One-Alpha Used For?
One-Alpha is primarily prescribed for the management of conditions related to calcium and phosphate imbalance‚ such as⁚
* Hypocalcemia⁚ Low levels of calcium in the blood․
* Secondary Hyperparathyroidism⁚ Overactivity of the parathyroid glands‚ often due to chronic kidney disease․
* Renal Osteodystrophy⁚ A bone disease that occurs in individuals with chronic kidney disease‚ characterized by abnormal bone formation and mineralization․
* Nutritional Rickets and Osteomalacia⁚ Softening of the bones due to vitamin D deficiency․
* Vitamin D-dependent Rickets⁚ A genetic disorder causing impaired vitamin D metabolism and bone abnormalities․
* Hypophosphatemic Rickets⁚ A group of disorders characterized by low phosphate levels and bone deformities․
How Does One-Alpha Work?
One-Alpha is converted by the liver into calcitriol‚ the active form of vitamin D․ Calcitriol then works by⁚
* Increasing calcium absorption⁚ Promotes the absorption of calcium from the intestines into the bloodstream․
* Regulating parathyroid hormone (PTH)⁚ Helps control the release of PTH‚ which plays a role in calcium balance․
* Promoting bone mineralization⁚ Supports the deposition of calcium and phosphate into the bones‚ making them stronger․
Benefits of One-Alpha
One-Alpha offers several advantages compared to other forms of vitamin D⁚
* Rapid onset of action⁚ Works faster than other vitamin D analogues‚ allowing for quicker correction of calcium levels․
* Precise dosage titration⁚ Easier to adjust the dosage to achieve optimal calcium levels and avoid complications․
* Reversible hypercalcemia⁚ If high calcium levels occur‚ they can be reversed quickly by stopping the medication․
