11 DESCRIPTION Bimatoprost ophthalmic solution, 0.03% is a synthetic prostamide analog with ocular hypotensive activity. Its chemical name is (Z)-7-[(1 R ,2 R ,3 R ,5 S )-3,5-Dihydroxy-2-[(1 E ,3 S )-3-hydroxy-5-phenyl-1-pentenyl]cyclopentyl]-5- N -ethylheptenamide, and its molecular weight is 415.58. Its molecular formula is C 25 H 37 NO 4 . Its chemical structure is: Bimatoprost is a powder, which is very soluble in ethyl alcohol and methyl alcohol and slightly soluble in water. Bimatoprost ophthalmic solution, 0.03% is a clear, isotonic, colorless, sterile ophthalmic solution with an osmolality of approximately 290 mOsmol/kg. Bimatoprost ophthalmic solution, 0.03% contains Active: bimatoprost 0.3 mg/mL; Inactives: benzalkonium chloride 0.05 mg/mL; disodium hydrogen phosphate heptahydrate; citric acid monohydrate; sodium chloride; and water for injection.

What Is Bimatoprost Used For?

1 INDICATIONS AND USAGE Bimatoprost ophthalmic solution, 0.03% is indicated for the reduction of elevated intraocular pressure in patients with open angle glaucoma or ocular hypertension. Bimatoprost ophthalmic solution, 0.03% is a prostaglandin analog indicated for the reduction of elevated intraocular pressure in patients with open angle glaucoma or ocular hypertension. ( 1 )

Dosage and Administration

2 DOSAGE AND ADMINISTRATION The recommended dosage is one drop in the affected eye(s) once daily in the evening. Bimatoprost ophthalmic solution, 0.03% should not be administered more than once daily since it has been shown that more frequent administration of prostaglandin analogs may decrease the intraocular pressure lowering effect. Reduction of the intraocular pressure starts approximately 4 hours after the first administration with maximum effect reached within approximately 8 to 12 hours. Bimatoprost ophthalmic solution, 0.03% may be used concomitantly with other topical ophthalmic drug products to lower intraocular pressure. If more than one topical ophthalmic drug is being used, the drugs should be administered at least five (5) minutes apart. One drop in the affected eye(s) once daily in the evening. ( 2 )

Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The following adverse reactions are described elsewhere in the labeling:

  • Pigmentation [see Warnings and Precautions (5.1) ]
  • Eyelash Changes [see Warnings and Precautions (5.2) ]
  • Intraocular Inflammation [see Warnings and Precautions (5.3) ]
  • Macular Edema [see Warnings and Precautions (5.4) ]
  • Hypersensitivity [see Contraindications (4) ] Most common adverse reaction (45%) is conjunctival hyperemia. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Gland Pharma at 864-879-9994 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In clinical trials, the most frequent events associated with the use of bimatoprost ophthalmic solution, 0.03% occurring in approximately 15% to 45% of patients, in descending order of incidence, included conjunctival hyperemia, growth of eyelashes, and ocular pruritus. Approximately 3% of patients discontinued therapy due to conjunctival hyperemia. Ocular adverse events occurring in approximately 3 to 10% of patients, in descending order of incidence, included ocular dryness, visual disturbance, ocular burning, foreign body sensation, eye pain, pigmentation of the periocular skin, blepharitis, cataract, superficial punctate keratitis, periorbital erythema, ocular irritation, and eyelash darkening. The following ocular adverse events reported in approximately 1 to 3% of patients, in descending order of incidence, included: eye discharge, tearing, photophobia, allergic conjunctivitis, asthenopia, increases in iris pigmentation, and conjunctival edema. In less than 1% of patients, intraocular inflammation was reported as iritis. Systemic adverse events reported in approximately 10% of patients were infections (primarily colds and upper respiratory tract infections). The following systemic adverse events reported in approximately 1 to 5% of patients, in descending order of incidence, included headaches, abnormal liver function tests, asthenia and hirsutism. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of bimatoprost ophthalmic solution, 0.03%. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The reactions, which have been chosen for inclusion due to either their seriousness, frequency of reporting, possible causal connection to bimatoprost ophthalmic solution, or a combination of these factors, include: abnormal hair growth, asthma-like symptoms, dizziness, dyspnea, eyelid edema, hypersensitivity reaction including signs and symptoms of eye allergy and allergic dermatitis, hypertension, nausea, and periorbital and lid changes associated with periorbital fat atrophy leading to skin tightness, deepening of the eyelid sulcus, eyelid ptosis, enophthalmos and eyelid retraction; and skin discoloration (non-periocular).

    • Contraindications

    4 CONTRAINDICATIONS Bimatoprost ophthalmic solution, 0.03% is contraindicated in patients with hypersensitivity to bimatoprost or to any of the ingredients [see Adverse Reactions (6.2)]. Hypersensitivity. ( 4 )

    Pregnancy and Breastfeeding

    8.1 Pregnancy Risk Summary There are no adequate and well-controlled studies of bimatoprost ophthalmic solution, 0.03% administration in pregnant women. There is no increase in the risk of major birth defects or miscarriages based on bimatoprost postmarketing experience. In embryofetal developmental studies, administration of bimatoprost in pregnant mice and rats during organogensis, resulted in abortion and early delivery at oral doses at least 33 times (mice) or 94 times (rats) the human exposure at the recommended clinical dose (based on blood area under the curve [AUC] levels). These adverse effects were not observed at 2.6 times (mice) and 47 times (rats) the human exposure at the recommended clinical dose. In pre/postnatal development studies, administration of bimatoprost to pregnant rats from organogenesis to the end of lactation resulted in reduced gestation length and fetal body weight, and increased fetal and pup mortality at oral doses at least 41 times the human systemic exposure at the recommended clinical dose (based on blood AUC levels). No adverse effects were observed in rat offspring at exposures estimated at 14 times the human exposure at the recommended clinical dose (based on blood AUC levels). Because animal reproductive studies are not always predictive of human response bimatoprost ophthalmic solution, 0.03% should be administered during pregnancy only if the potential benefit justifies the potential risk to the fetus. Data Animal Data In an embryofetal development rat study, abortion was observed in pregnant rats administered bimatoprost orally during organogenesis at 0.6 mg/kg/day (94 times the human systemic exposure at the recommended human ophthalmic dose [RHOD], based on AUC). The No Observed Adverse Effect Level (NOAEL) for abortion was 0.3 mg/kg/day (estimated at 47 times the human systemic exposure at the RHOD, based on AUC). No abnormalities were observed in rat fetuses at doses up to 0.6 mg/kg/day. In an embryofetal development...

    Overdosage

    10 OVERDOSAGE No information is available on overdosage in humans. If overdose with bimatoprost ophthalmic solution, 0.03% occurs, treatment should be symptomatic. In oral (by gavage) mouse and rat general toxicity studies, doses up to 100 mg/kg/day did not produce any toxicity. This dose expressed as mg/m 2 is at least 70 times higher than the accidental dose of one bottle of bimatoprost ophthalmic solution, 0.03% for a 10 kg child.
