  • Prophylaxis of Corneal Graft Rejection (short-term under specialist care)
  • Inflammatory Pseudotumor of the Orbit (when systemic steroids are not suitable)
Dosage & Administration

General Instructions

  • Route: Ophthalmic (topical)
  • Form: Ophthalmic suspension (commonly 1% w/v)
  • Shake well before use.

Adults:

  • Mild to Moderate Inflammation:
    1–2 drops in the affected eye(s) 2 to 4 times daily
  • Severe Inflammation:
    1–2 drops every 1 to 2 hours, then reduce frequency as symptoms improve
  • Post-operative Use:
    1–2 drops 4 times daily beginning 24 hours after surgery, typically for 1–2 weeks

Pediatrics:

  • Children ≥2 years:
    Same dosage as adults under ophthalmologist supervision
  • Children <2 years:
    Use only if essential, with close monitoring

Elderly:

  • No dose adjustment required, but monitor intraocular pressure (IOP) closely

Renal/Hepatic Impairment:

  • Not systemically significant; no dosage adjustment needed

Important Notes:

  • Do not discontinue abruptly after prolonged use—taper slowly
  • Avoid contact lenses during active treatment
Mechanism of Action (MOA)

Prednisolone acetate is a synthetic glucocorticoid that penetrates the corneal epithelium and binds to intracellular glucocorticoid receptors in ocular cells. This receptor-ligand complex enters the nucleus and modifies the transcription of inflammatory genes by suppressing pro-inflammatory cytokines (e.g., interleukins, prostaglandins, TNF-alpha) and increasing anti-inflammatory proteins like lipocortin-1. The result is a reduction in leukocyte infiltration, edema, capillary dilation, fibrin deposition, and fibroblast proliferation, effectively suppressing ocular inflammation, redness, and discomfort.

Pharmacokinetics

Following ophthalmic administration:

  • Absorption:
    Rapidly penetrates the cornea and is absorbed into the anterior segment. Systemic absorption is minimal with intact epithelium.
  • Bioavailability:
    High local ocular bioavailability; low systemic bioavailability (<5%)
  • Distribution:
    Concentrated in corneal and anterior ocular tissues; negligible systemic distribution
  • Metabolism:
    Hydrolyzed locally in ocular tissues to active prednisolone. Systemically absorbed amounts are metabolized by the liver (mainly via CYP3A4).
  • Half-life:
    Ocular half-life: ~4–6 hours
    Systemic half-life (if absorbed): ~2–4 hours
  • Elimination:
    Inactive metabolites are excreted by the kidneys
Pregnancy Category & Lactation
  • Pregnancy:
    FDA Category C
    Animal studies show risk of fetal harm with corticosteroids. No adequate human studies. Use only if benefits outweigh potential risks. Avoid prolonged or repeated use during pregnancy.
  • Lactation:
    Unlikely to be excreted in breast milk in significant amounts after topical ophthalmic use. Minimal risk to infants. Caution is advised during prolonged treatment; monitor infant for signs of corticosteroid exposure (e.g., poor weight gain, adrenal suppression).
Therapeutic Class
  • Primary Class: Ophthalmic Anti-inflammatory
  • Subclass: Synthetic Glucocorticoid (Topical Corticosteroid)
Contraindications
  • Hypersensitivity to prednisolone acetate or any component of the formulation
  • Viral infections of the eye, including:
    • Active herpes simplex keratitis (dendritic or geographic ulcers)
    • Vaccinia
    • Varicella (chickenpox)
  • Mycobacterial infections of the eye, such as tuberculosis
  • Fungal diseases of ocular structures
  • Untreated purulent ocular infections
  • Corneal epithelial damage or thinning
Warnings & Precautions
  • Glaucoma Risk:
    Prolonged use may increase intraocular pressure (IOP) → optic nerve damage, visual field loss
  • Cataract Formation:
    Risk of posterior subcapsular cataracts with chronic use
  • Secondary Infections:
    May suppress immune response and mask bacterial, fungal, or viral eye infections
  • Corneal Thinning or Perforation:
    Especially in those with preexisting thinning or ulcers
  • Delayed Wound Healing:
    Can delay healing of corneal wounds, especially post-surgery
  • Monitoring:
    Monitor IOP if used longer than 10 days
    Use fluorescein staining before initiation to rule out corneal epithelial defects
  • Herpes Simplex:
    Use only under strict ophthalmologic supervision due to risk of reactivation
Side Effects

Common (Mild, Transient):

  • Burning or stinging sensation after instillation
  • Blurred vision
  • Eye redness
  • Foreign body sensation
  • Tearing or dryness

Less Common / Serious:

  • Elevated intraocular pressure
  • Posterior subcapsular cataract formation
  • Superinfection (fungal or bacterial)
  • Corneal thinning, ulceration, or perforation
  • Reactivation of herpes simplex keratitis
  • Hypersensitivity reactions (itching, swelling)

Adverse effects are dose- and duration-dependent.

Drug Interactions
  • Live Vaccines:
    Systemic immunosuppression from absorbed corticosteroids may interfere with vaccine efficacy
  • Ocular NSAIDs:
    May impair corneal healing when used concurrently
  • Multiple Ophthalmic Products:
    Separate instillation by at least 5 minutes to avoid washout
  • Systemic CYP3A4 Inhibitors:
    May reduce clearance of systemically absorbed prednisolone, but unlikely to be clinically significant at ophthalmic doses
Recent Updates or Guidelines
  • AAO Guidelines:
    Reinforce short-term corticosteroid use and emphasize intraocular pressure monitoring in all patients treated beyond 10 days
  • Label Updates:
    Include stronger precautions regarding secondary infections and corneal thinning
  • Post-Surgical Use Recommendations:
    Typically limited to 2 weeks or less unless otherwise indicated by the surgeon
