Medoxa (Prednisone)

Prednisone is used to modulate inflammatory and immune pathways in several chronic and acute disorders.

• Asthma: reduces airway inflammation, improving breathing and decreasing frequency of exacerbations.
• Chronic obstructive pulmonary disease (COPD): diminishes pulmonary inflammation, helping to relieve symptoms and prevent flare‑ups.
• Rheumatoid arthritis: suppresses joint inflammation, relieving pain, swelling and preserving joint function.
• Systemic lupus erythematosus: controls systemic immune activity, reducing organ inflammation and disease activity.
• Dermatologic inflammatory conditions: alleviates skin inflammation, decreasing redness, itching and lesion formation.
• Allergic reactions: mitigates severe allergic responses by dampening immune‑mediated inflammation.

• Prednisone exerts its effects by diffusing across cell membranes and binding to intracellular glucocorticoid receptors. The drug‑receptor complex translocates to the nucleus, where it binds glucocorticoid response elements and modulates gene transcription. This up‑regulates anti‑inflammatory proteins such as annexin‑1 and down‑regulates pro‑inflammatory cytokines (e.g., IL‑1, IL‑6, TNF‑α), further interfering with transcription factors such as NF‑κB, resulting in broad immunosuppressive and anti‑inflammatory activity.

Prednisone may cause a range of adverse reactions, varying in frequency and severity.

Common Side Effects

• Increased appetite and weight gain.
• Insomnia or difficulty sleeping.
• Mood changes, including irritability or euphoria.
• Elevated blood glucose levels.
• Fluid retention leading to mild swelling.
• Gastrointestinal discomfort.

Serious or Rare Side Effects

• Adrenal insufficiency on abrupt discontinuation.
• Severe infections due to immunosuppression.
• Osteoporosis and increased fracture risk.
• Cataracts or glaucoma.
• Psychosis or severe mood disturbances.
• Anaphylactic or severe allergic reactions.

When using Prednisone, careful monitoring and specific precautions are essential.

• Tapering: avoid abrupt discontinuation to prevent adrenal insufficiency.
• Infection risk: monitor for signs of infection, as immunosuppression may mask symptoms.
• Blood glucose: patients with diabetes should have glucose levels closely monitored.
• Bone health: consider calcium and vitamin D supplementation to mitigate osteoporosis risk.
• Pregnancy: use only if benefit outweighs risk; category B.
• Store at ambient temperature: keep below 25°C, in original container, protect from moisture.

Prednisone can interact with several medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid)

• Ketoconazole: may increase prednisone levels leading to toxicity.
• Live vaccines: risk of severe infection; avoid concurrent use.
• Anticoagulants (e.g., warfarin): may enhance anticoagulant effect.
• Diabetes medications: may require dose adjustment due to hyperglycemia.
• NSAIDs: increase risk of gastrointestinal ulceration.

Moderate Interactions (Monitor Closely)

• Antihypertensives: may reduce efficacy, monitor blood pressure.
• Inactivated vaccines: may have reduced efficacy, monitor response.
• CYP450 inducers (e.g., rifampin): may lower prednisone concentrations.
