LOTEMAX Loteprednol Etabonate 5mg / mL (0.5%) Ophthalmic Suspension 5mL
Indications/Uses
Loteprednol Etabonate (LOTEMAX) is less effective than prednisolone acetate 1% in two 28-day controlled clinical studies in acute anterior uveitis, where 72% of patients treated with Loteprednol Etabonate (LOTEMAX) experienced resolution of anterior chamber cells, compared to 87% of patients treated with prednisolone acetate 1%. The incidence of patients with clinically significant increases in IOP (≥10 mmHg) was 1% with Loteprednol Etabonate (LOTEMAX) and 6% with prednisolone acetate 1%. Loteprednol Etabonate (LOTEMAX) should not be used in patients who require a more potent corticosteroid for this indication.
Loteprednol Etabonate (LOTEMAX) is also indicated for the treatment of post-operative inflammation following ocular surgery. For short-term treatment of dry eye syndrome (DES).
Dosage/Direction for Use
Steroid Responsive Disease Treatment: Apply one to two drops of Loteprednol Etabonate (LOTEMAX) into the conjunctival sac of the affected eye(s) four times daily. During the initial treatment within the first week, the dosing may be increased, up to 1 drop every hour if necessary. Care should be taken not to discontinue therapy prematurely. If signs and symptoms fail to improve after two days, the patient should be re-evaluated (see Precautions).
Post-Operative Inflammation: Apply one to two drops of Loteprednol Etabonate (LOTEMAX) into the conjunctival sac of the operated eye(s) two times daily beginning 24 hours after surgery and continuing throughout the first 2 weeks of the postoperative period.
Overdosage
Contraindications
Warnings
Prolonged use of corticosteroids may suppress the host response and thus increase the hazard of secondary ocular infections. In those diseases causing thinning of the cornea or sclera, perforations have been known to occur with the use of topical steroids. In acute purulent conditions of the eye, steroids may mask infection or enhance existing infection.
Use of ocular steroids may prolong the course and may exacerbate the severity of many viral infections of the eye (including herpes simplex). Employment of a corticosteroid medication in the treatment of patients with a history of herpes simplex requires great caution.
The use of steroids after cataract surgery may delay healing and increase the incidence of bleb formation.
Special Precautions
If signs and symptoms fail to improve after two days, the patient should be re-evaluated.
If this product is used for 10 days or longer, intraocular pressure should be monitored even though it may be difficult in children and uncooperative patients (see Warnings).
Fungal infections of the cornea are particularly prone to develop coincidentally with long-term local steroid application. Fungus invasion must be considered in any persistent corneal ulceration where a steroid has been used or is in use. Fungal cultures should be taken when appropriate.
Information for Patients: This product is sterile when packaged. Patients should be advised not to allow the dropper tip to touch any surface, as this may contaminate the suspension. If pain develops, redness, itching or inflammation becomes aggravated, the patient should be advised to consult a physician. As with all ophthalmic preparations containing benzalkonium chloride, patients should be advised not to wear soft contact lenses when using Loteprednol Etabonate (LOTEMAX).
Carcinogenesis, Mutagenesis, Impairment of Fertility: Low-term animal studies have not been conducted to evaluate the carcinogenic potential of loteprednol etabonate.
Use in children: Safety and effectiveness in pediatric patients have not been established.
Use In Pregnancy & Lactation
Oral exposure of female rats to 50 mg/kg/day of loteprednol etabonate from the start of the fetal period through the end of lactation, a maternally toxic treatment regimen (significantly decreased body weight gain), gave rise to decreased growth and survival, and retarded development in the offspring during lactation; the NOEL for these effects was 5 mg/kg/day. Loteprednol etabonate had no effect on the duration of gestation or parturition when administered orally to pregnant rats at doses up to 50 mg/kg/day during the fetal period.
Nursing Mothers: It is not known whether topical ophthalmic administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in human milk. Systemic steroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. Caution should be exercised when Loteprednol Etabonate (LOTEMAX) is administered to a nursing woman.
Adverse Reactions
Ocular adverse reactions occurring in 5-15% of patients treated with loteprednol etabonate ophthalmic suspension (0.2%-0.5%) in clinical studies included abnormal vision/blurring, burning on instillation, chemosis, discharge, dry eyes, epiphora, foreign body sensation, itching, injection, and photophobia. Other ocular adverse reactions occurring in less than 5% of patients include conjunctivitis, corneal abnormalities, eyelid erythema, keratoconjunctivitis, ocular irritation/pain/discomfort, papillae, and uveitis. Some of these events were similar to the underlying ocular disease being studied.
Non-ocular adverse reactions occurred in less than 15% of patients. These include headache, rhinitis and pharyngitis.
In a summation of controlled, randomized studies of individuals treated for 28 days or longer with loteprednol etabonate, the incidence of significant elevation of intraocular pressure (≥10 mmHg) was 2% (15/901) among patients receiving loteprednol etabonate, 7% (11/164) among patients receiving 1% prednisolone acetate and 0.5% (3/583) among patients receiving placebo.
Storage
Action
Loteprednol etabonate is structurally similar to other corticosteroids. However, the number 20 position ketone group is absent. It is highly lipid soluble which enhances its penetration into cells. Loteprednol etabonate is synthesized through structural modifications of prednisolone-related compounds so that it will undergo a predictable transformation to an inactive metabolite. Based upon in vivo and in vitro preclinical metabolism studies, loteprednol etabonate undergoes extensive metabolism to inactive carboxylic acid metabolites.
Results from a bioavailability study in normal volunteers established that plasma levels of loteprednol etabonate and △1 cortienic acid etabonate (PJ 91), its primary, inactive metabolite, were below the limit of quantitation (1 ng/mL) at all sampling times. The results were obtained following the ocular administration of one drop in each eye of 0.5% loteprednol etabonate 8 times daily for 2 days or 4 times daily for 42 days. This study suggests that limited (<1 ng/ml) systemic absorption occurs with Loteprednol Etabonate (LOTEMAX).
Pharmacodynamics: Clinical Studies: Post-Operative Inflammation: Placebo-controlled clinical studies demonstrated that Loteprednol Etabonate (LOTEMAX) is effective for the treatment of anterior chamber inflammation as measured by cell and flare.
Giant Papillary Conjunctivitis: Placebo-controlled clinical studies demonstrated that Loteprednol Etabonate (LOTEMAX) was effective in reducing the signs and symptoms of giant papillary conjunctivitis after 1 week of treatment and continuing for up to 6 weeks while on treatment.
Seasonal Allergic Conjunctivitis: A placebo-controlled clinical study demonstrated that Loteprednol Etabonate (LOTEMAX) was effective in reducing the signs and symptoms of allergic conjunctivitis during peak periods of pollen exposure.
Uveitis: Controlled clinical studies of patients with uveitis demonstrated that Loteprednol Etabonate (LOTEMAX) was less effective than prednisolone acetate 1%. Overall, 72% of patients treated with Loteprednol Etabonate (LOTEMAX) experienced resolution of anterior chamber cell by day 28, compared to 87% of patients treated with 1% prednisolone acetate. The incidence of patients with clinically significant increases in IOP (≥10 mmHg) was 1% with Loteprednol Etabonate (LOTEMAX) and 6% with prednisolone acetate 1%.
