Prednisolone: Alternative Names and Formulations
Prednisolone is also known as prednisolone sodium phosphate, prednisolone acetate, and is marketed under various brand names including Kam Predisol, with generic formulations widely available. 1, 2
Chemical Forms and Salt Derivatives
Prednisolone exists in multiple chemical forms that differ in their pharmacological properties:
- Prednisolone sodium phosphate: A water-soluble salt form used primarily in oral solutions and intravenous preparations 2, 3
- Prednisolone acetate: A suspension form used predominantly in ophthalmic preparations, with lower water solubility but potentially different bioavailability characteristics 3, 4, 5
- Prednisolone base: The parent compound, with dosing often referenced as "prednisolone equivalents" when comparing different corticosteroid formulations 6, 7
Brand Names by Region
The medication is marketed under different brand names depending on geographic location 1:
- Uganda: Kam Predisol (manufactured by Kampala Pharmaceuticals Industries 1996 Limited)
- Nigeria: Various brand names available, though specific brands not consistently documented
- Multiple regions: Generic formulations are widely available in 5 mg and 50 mg tablet strengths
Formulation-Specific Considerations
The sodium phosphate and acetate forms are NOT interchangeable in all clinical contexts, particularly in ophthalmology where prednisolone acetate suspensions demonstrate different particle size characteristics and potentially superior ocular bioavailability compared to sodium phosphate solutions 4, 5. However, for systemic administration, these differences are less clinically significant 3.
The oral solution formulation (prednisolone sodium phosphate) contains 20.2 mg prednisolone sodium phosphate per 5 mL, equivalent to 15 mg prednisolone base, with inactive ingredients including alcohol (1.8%), glycerin, sorbitol, and grape flavoring 2.
Related Corticosteroid Terminology
When comparing corticosteroid potency and dosing, prednisolone is often referenced alongside other glucocorticoids including prednisone, methylprednisolone, hydrocortisone, and dexamethasone 8, 9, 6. Prednisolone and prednisone are distinct molecules, though prednisone is converted to prednisolone in the liver, making prednisolone the active form 10.
