How Lotrel T works
Lotrel T is a combination of two medicines: Loteprednol etabonate and Tobramycin. Loteprednol etabonate is a steroid which blocks the production of certain chemical messengers (prostaglandins) that make the eye red, swollen and itchy. Tobramycin is an antibiotic. It stops bacterial growth in the eye by preventing the synthesis of essential proteins required by bacteria to carry out vital functions.
Indication
Keratitis, Allergic conjunctivitis, Iritis, Ocular inflammation, Bacterial ocular infection, Cyclitis
Adult Dose
Ocular Inflammation
Indicated for steroid-responsive ocular inflammations with risk of superficial bacterial infections
Adult: Instill 1 or 2 drops of into the conjunctival sac of the affected eye(s) every 4 to 6 hours.; may use as frequently as q1-2hr during first 24-48 hr
Decrease frequency of administration as signs and symptoms improve
Child Dose
Safety & efficacy not been established.
Contraindication
Hypersensitivity to any component of the formulation or to other corticosteroids
Viral, mycobacterial & fungal eye infections
Mode of Action
Loteprednol is a synthetic nonfluorinated glucocorticoid. It stimulates the production of lipicortins, proteins that modulate the activity of prostaglandins and leukotrienes.
Tobramycin acts by binding to 30S ribosomal subunits thus interfering with bacterial protein synthesis. It is active against many aerobic gram-negative bacteria and some aerobic gram-positive bacteria but inactive against Chlamydia, fungi, viruses, and most anaerobic bacteria.
Precaution
History of herpes simplex infections
May exacerbate infections by nonsusceptible organisms
Monitor IOP if used >10 d
Bacterial keratitis reported from inadvertent contamination of multiple dose ophthalmic solution
Immunosuppression resulting from prolonged use of steroid use may result in secondary bacterial and fungal infections; steroids may also mask symptoms of infections and enhance existing ocular infections
Ocular hypertension and/or glaucoma reported with prolonged corticosteroid use
Discontinue use if sensitivity reaction to tobramycin develops
Corticosteroid use following cataract surgery may delay healing
Lactation: Excretion in milk unknown; use caution
Side Effect
Prolonged use may increase: IOP, which may be associated with possible development of glaucoma and infrequent optic nerve damage; posterior sub-capsular cataract formation and perforation of the globe where there is thinning of the cornea or sclera.
The most frequent adverse reactions to topical tobramycin are hypersensitivity and localized ocular toxicity, including lid itching and swelling and conjunctival erythema.
Interaction
Enhanced neurotoxic and nephrotoxic effects w/ other aminoglycosides (e.g. amikacin, streptomycin), cefaloridine, viomycin, polymyxin B, colistin, cisplatin and vancomycin. Enhanced toxicity w/ potent diuretics (e.g. ethacrynic acid, furosemide). Prolonged secondary apnoea may occur when given to anaesthetised patients receiving neuromuscular blocking agents (e.g. succinylcholine, tubocurarine, decamethonium). Increased risk of nephrotoxicity w/ ciclosporin and other antibacterials (e.g. cephalosporins). Antagonistic effect w/ neostigmine and pyridostigmine. May potentiate the effect of warfarin and phenindione.
