Introduction

Synthetic nonfluorinated corticosteroid.

Uses for Loteprednol

Allergic Conjunctivitis

Symptomatic relief of seasonal allergic (hay fever, pollinosis) conjunctivitis.

Inflammatory Ocular Disorders

Symptomatic relief of corticosteroid-responsive inflammatory conditions of the palpebral and bulbar conjunctiva, cornea, and anterior segment of the globe (i.e., allergic conjunctivitis, acne rosacea keratitis, superficial punctate keratitis, herpes zoster keratitis, iritis, and cyclitis. Use in conjunction with appropriate anti-infective therapy in some cases of conjunctival infection, when the benefits of reducing edema and inflammation outweigh the risks associated with use of topical corticosteroids.

Loteprednol etabonate 0.5% less effective than prednisolone acetate 1% in the management of anterior uveitis.

Postoperative Ocular Inflammation

Treatment of postoperative ocular inflammation following ocular surgery.

Bacterial Ophthalmic Infections

Used in fixed combination with tobramycin in certain bacterial ocular infections.

Loteprednol Dosage and Administration

General

Administration

Ophthalmic Administration

Apply topically to the eyes as an ophthalmic suspension.

In fixed combination with tobramycin, apply topically to the eyes as an ophthalmic suspension.

Shake suspension vigorously prior to use.

Avoid contamination of the dropper tip.

Dosage

Available as loteprednol etabonate; dosage expressed in terms of the salt.

Adults

Seasonal Allergic Conjunctivitis
Ophthalmic

1 drop of a 0.2% suspension in the affected eye(s) 4 times daily.

Inflammatory Ocular Disorders
Ophthalmic

1 or 2 drops of a 0.5% suspension in the affected eye(s) 4 times daily. During initial treatment (within the first week), may increase dosage up to 1 drop every hour. When improvement occurs, decrease frequency of application.

Postoperative Ocular Inflammation
Ophthalmic

1 or 2 drops of a 0.5% suspension to the eye(s) undergoing surgery 4 times daily beginning 24 hours after surgery and continuing for 2 weeks after surgery.

Bacterial Ophthalmic Infections
Ophthalmic

Loteprednol etabonate and tobramycin ophthalmic suspension: 1 or 2 drops in the affected eye(s) every 4–6 hours. During the initial 24–48 hours, dosing may be increased to every 1–2 hours. When improvement occurs, decrease frequency of application.

Cautions for Loteprednol

Contraindications

Warnings/Precautions

Warnings

Ocular Effects

Risk of glaucoma (with damage to optic nerve), defects in visual acuity and fields of vision, and posterior subcapsular cataract formation with prolonged use of corticosteroids. Use with caution in the presence of glaucoma. Marked elevation in IOP (≥10 mm Hg) reported with loteprednol use; incidence lower than that reported with prednisolone acetate.

In conditions causing thinning of the cornea or sclera, perforations reported with use of topical corticosteroids.

Corticosteroid use after cataract surgery may delay healing and increase incidence of bleb formation.

Immunosuppressive Effects

Risk of secondary ocular infection with prolonged use of corticosteroids.

In acute purulent ocular conditions, corticosteroids may mask infection or exacerbate existing infection.

Risk of prolongation or exacerbation of ocular viral infections (e.g., herpes simplex) with ophthalmic corticosteroids. Use with extreme caution in patients with history of herpes simplex.

General Precautions

Use of Fixed Combination

Observe the usual precautions associated with tobramycin therapy when loteprednol is used in fixed combination with tobramycin.

Evaluation of Ocular Condition

Initial prescription or renewal of medication order beyond 14 days should be provided only after examination of the patient with the aid of magnification (e.g., slit lamp biomicroscopy, fluorescein staining where appropriate).

Fungal Infections

Long-term local corticosteroid application associated with development of fungal infections of the cornea. Consider fungus invasion in patients with persistent corneal ulceration who have or are receiving corticosteroid therapy; obtain fungal cultures when appropriate.

Specific Populations

Pregnancy

Category C.

Lactation

Not known whether distributed into human milk following topical application to the eye. Systemic corticosteroids distributed into human milk and may suppress growth, interfere with endogenous corticosteroid production, and cause other adverse effects. Use with caution.

Pediatric Use

Safety and efficacy not established in children <18 years of age.

Common Adverse Effects

Abnormal/blurred vision, burning on instillation, chemosis, discharge, dry eyes, epiphora, foreign body sensation, itching, injection, photophobia.

Adverse systemic events include headache, rhinitis, and pharyngitis.

Loteprednol Pharmacokinetics

Absorption

Bioavailability

Limited systemic exposure following topical application to the eye; plasma concentrations usually are undetectable.

Onset

In clinical studies in patients with seasonal allergic conjunctivitis, improvement in ocular itching and bulbar conjunctival injection occurred within 2 hours following initiation of therapy.

In clinical studies in patients with contact lens-associated giant papillary conjunctivitis, improvement in papillae, conjunctival injection and itching, and lens intolerance was evident within 1 week of therapy.

Duration

In patients with seasonal allergic conjunctivitis, improvement in ocular itching and bulbar conjunctival injection persisted through day 14 of therapy.

In patients with contact lens-associated giant papillary conjunctivitis, improvement in papillae, conjunctival injection and itching, and lens intolerance persisted for up to 6 weeks while therapy was continued.

Elimination

Metabolism

Undergoes extensive metabolism to inactive carboxylic acid metabolites.

Stability

Storage

Ophthalmic

Suspension

Upright at 15–25°C. Do not freeze.
