Prednisone IP/USP/BP/EP – A Comprehensive Overview of a Widely Used Corticosteroid API

By Swapnroop Drugs & Pharmaceuticals

Introduction

Prednisone is a synthetic glucocorticoid corticosteroid extensively used in the treatment of inflammatory, allergic, autoimmune, and immunosuppressive conditions. Due to its proven efficacy, predictable pharmacokinetics, and broad therapeutic utility, Prednisone remains one of the most prescribed corticosteroids worldwide.

Recognized and standardized under major global pharmacopoeias — Indian Pharmacopoeia (IP), United States Pharmacopeia (USP), British Pharmacopoeia (BP), and European Pharmacopoeia (EP) — Prednisone API is a critical ingredient in regulated pharmaceutical markets.

At Swapnroop Drugs & Pharmaceuticals, we supply high-quality Prednisone IP/USP/BP/EP manufactured under stringent GMP conditions, ensuring consistency, safety, and regulatory compliance.

1. Chemical Identity & Characteristics

Prednisone is a synthetic corticosteroid derived from cortisone, designed to enhance anti-inflammatory potency while maintaining controlled metabolic activity.

Key Chemical Details:

• Molecular Formula: C₂₁H₂₆O₅
• Molecular Weight: ~358.43 g/mol
• Appearance: White or almost white crystalline powder
• Solubility: Practically insoluble in water; soluble in alcohol and organic solvents

Prednisone itself is a prodrug, which is converted in the liver to its active form, prednisolone, enabling effective systemic anti-inflammatory action.

2. Pharmacopoeial Standards (IP / USP / BP / EP)

Prednisone is officially listed in all major pharmacopoeias, each defining stringent quality parameters:

Indian Pharmacopoeia (IP)

• Identity testing using spectroscopic and chromatographic methods
• Assay limits and impurity profiling
• Residual solvent and stability requirements

United States Pharmacopeia (USP)

• Precise HPLC assay methods
• Strict limits on related substances
• Uniformity and stability compliance

British & European Pharmacopoeia (BP/EP)

• Harmonized quality specifications
• Control of degradation products
• Defined storage and handling conditions

Swapnroop Drugs & Pharmaceuticals ensures full compliance with these pharmacopoeial standards, enabling seamless regulatory acceptance across global markets.

3. Mechanism of Action

Prednisone exerts its therapeutic effects by acting as a glucocorticoid receptor agonist after conversion to prednisolone in the body.

Its actions include:

• Suppression of inflammatory mediator synthesis
• Inhibition of immune cell activation
• Reduction of capillary permeability and tissue edema
• Modulation of gene transcription related to inflammation and immunity

This makes Prednisone highly effective in both acute and chronic inflammatory conditions.

4. Therapeutic Applications

Prednisone’s versatility allows its use across multiple therapeutic areas:

Anti-inflammatory & Immunosuppressive Uses

• Rheumatoid arthritis and other autoimmune disorders
• Inflammatory bowel disease
• Systemic lupus erythematosus

Allergic & Respiratory Conditions

• Severe allergic reactions
• Asthma and chronic respiratory disorders

Oncology & Hematology

• Leukemia and lymphoma management
• Prevention of chemotherapy-induced inflammation

Other Medical Uses

• Nephrotic syndrome
• Organ transplant immunosuppression
• Endocrine disorders

5. Pharmacokinetics & Safety Profile

Prednisone is well absorbed orally and undergoes hepatic conversion to prednisolone, which is responsible for its pharmacological activity.

Key Safety Considerations:

• Dose-dependent systemic effects
• Long-term use may require tapering to avoid adrenal suppression
• Widely studied with well-established clinical guidelines

When used under medical supervision and appropriate dosing, Prednisone remains a safe and effective therapeutic option.
