Hydventia (Hydrocortisone)

Hydrocortisone is a corticosteroid that modulates inflammatory and immune pathways in several endocrine and inflammatory conditions.

• Adrenal insufficiency: restores physiologic cortisol levels in patients with primary or secondary adrenal failure.
• Congenital adrenal hyperplasia: provides glucocorticoid replacement to suppress excess androgen production.
• Rheumatoid arthritis and other inflammatory disorders: reduces joint inflammation and pain when systemic therapy is required.

• Hydrocortisone binds to intracellular glucocorticoid receptors, forming a complex that translocates to the nucleus and alters 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), resulting in decreased leukocyte migration, reduced capillary permeability, and suppression of the hypothalamic‑pituitary‑adrenal axis feedback loop.

Hydrocortisone may cause a range of adverse reactions, from mild to severe, depending on dose and duration.

Common Side Effects

• Increased appetite: may lead to weight gain.
• Fluid retention: can cause peripheral edema.
• Mood changes: irritability or mild euphoria.
• Gastrointestinal discomfort: dyspepsia or gastritis.
• Elevated blood glucose: transient hyperglycaemia.
• Skin thinning: easy bruising or striae.

Serious or Rare Side Effects

• Severe infection: immunosuppression may predispose to opportunistic infections.
• Osteoporosis: long‑term use can reduce bone mineral density.
• Adrenal suppression: abrupt discontinuation may precipitate adrenal crisis.
• Hypertension: persistent elevation of blood pressure.
• Psychiatric disturbances: psychosis or severe mood swings.
• Peptic ulcer disease: risk of gastrointestinal bleeding.

Before initiating therapy, consider patient‑specific factors and monitor for potential complications.

• Assess adrenal function: confirm diagnosis of insufficiency before replacement.
• Screen for infections: treat active infections prior to starting therapy.
• Monitor glucose: patients with diabetes may require dose adjustments.
• Evaluate bone health: consider calcium/vitamin D supplementation for long‑term use.
• Review concomitant drugs: avoid agents that increase glucocorticoid exposure.
• Store below 25°C: keep in the original container, protect from moisture and direct sunlight.

Hydrocortisone can interact with several drug classes, altering efficacy or safety.

Major Interactions (Avoid)

• CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin): may increase systemic exposure and risk of toxicity.
• Anticoagulants (e.g., warfarin): glucocorticoids can enhance anticoagulant effect, raising bleeding risk.

Moderate Interactions (Monitor Closely)

• Non‑steroidal anti‑inflammatory drugs (NSAIDs): combined use may increase gastrointestinal ulcer risk.
• Diuretics (e.g., furosemide): may potentiate hypokalaemia.
• Antidiabetic agents: glucocorticoids may raise blood glucose, requiring dose adjustments.
• Vaccines: live vaccines may be less effective; consider timing of administration.
