FDA Label for Atropine Sulfate

2 Dosage And Administration

In individuals from three (3) months of age or greater, 1 drop topically to the cul-de-sac of the conjunctiva in one or both eyes as indicated, forty minutes prior to the intended maximal dilation time.

•  In individuals 3 years of age or greater, doses may be repeated up to twice daily as needed.

Discard the single-dose vial immediately after use in one or both eyes.

3 Dosage Forms And Strengths

Atropine Sulfate Ophthalmic Solution, USP 1%: each mL contains 10 mg of atropine sulfate.

4 Contraindications

Atropine Sulfate Ophthalmic Solution, USP 1% should not be used in anyone who has demonstrated a previous hypersensitivity or known allergic reaction to any ingredient of the formulation because it may recur.

5.1 Photophobia And Blurred Vision

Photophobia and blurred vision due to pupil unresponsiveness and cycloplegia may last up to 2 weeks.

5.2 Elevation Of Blood Pressure

Elevation in blood pressure from systemic absorption has been reported following conjunctival instillation of recommended doses of Atropine Sulfate Ophthalmic Solution, USP 1%.

5.3 Potential For Eye Injury Or Contamination

To avoid the potential for eye injury or contamination, care should be taken to avoid touching the single-dose vial to the eye or to any other surface.

6 Adverse Reactions

The following serious adverse reactions are described below and elsewhere in the labeling:

• •Photophobia and Blurred Vision [see Warnings and Precautions (5.1)]
• •Elevation in Blood Pressure [see Warnings and Precautions (5.2)]

The following adverse reactions have been identified following use of atropine sulfate ophthalmic solution. 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.

6.1 Ocular Adverse Reactions

Eye pain and stinging occurs upon instillation of atropine sulfate ophthalmic solution. Other commonly occurring adverse reactions include blurred vision, photophobia, superficial keratitis and decreased lacrimation. Allergic reactions such as papillary conjunctivitis, contact dermatitis, and eyelid edema may also occur less commonly.

6.2 Systemic Adverse Reactions

Systemic effects of atropine are related to its anti-muscarinic activity. Systemic adverse events reported include dryness of skin, mouth, and throat from decreased secretions from mucous membranes; drowsiness, restlessness, irritability or delirium from stimulation of the central nervous system; tachycardia; flushed skin of the face and neck.

7.1 Monoamine Oxidase Inhibitors (Maoi)

The use of atropine and monoamine oxidase inhibitors (MAOI) is generally not recommended because of the potential to precipitate hypertensive crisis.

8.1 Pregnancy

Risk Summary

There are no adequate and well-controlled studies of Atropine Sulfate Ophthalmic Solution, USP 1% administration in pregnant women to inform a drug-associated risk. Adequate animal development and reproduction studies have not been conducted with atropine sulfate. In humans, 1% atropine sulfate is systemically bioavailable following topical ocular administration [see Clinical Pharmacology (12.3)]. Atropine Sulfate Ophthalmic Solution, USP 1% should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus.

8.2 Lactation

Risk Summary

There is no information to inform risk regarding the presence of atropine in human milk following ocular administrations of Atropine Sulfate Ophthalmic Solution, USP 1% to the mother. The effects on breastfed infants and the effects on milk production are also unknown. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Atropine Sulfate Ophthalmic Solution, USP 1% and any potential adverse effects on the breastfed child from Atropine Sulfate Ophthalmic Solution, USP 1%.

8.4 Pediatric Use

Due to the potential for systemic absorption, the use of Atropine Sulfate Ophthalmic Solution, USP 1% in children under the age of 3 months is not recommended and the use in children under 3 years of age should be limited to no more than one drop per eye per day. Safety and efficacy in children above the age of 3 months has been established in adequate and well controlled trials.

8.5 Geriatric Use

No overall differences in safety and effectiveness have been observed between elderly and younger adult patients.

10 Overdosage

In the event of accidental ingestion or toxic overdosage with Atropine Sulfate Ophthalmic Solution, USP 1%, supportive care may include a short acting barbiturate or diazepam as needed to control marked excitement and convulsions. Large doses for sedation should be avoided because central depressant action may coincide with the depression occurring late in atropine poisoning. Central stimulants are not recommended.

Physostigmine, given by slow intravenous injection of 1 to 4 mg (0.5 to 1 mg in pediatric populations), rapidly abolishes delirium and coma caused by large doses of atropine. Since physostigmine is rapidly destroyed, the patient may again lapse into coma after one to two hours, and repeated doses may be required.

Artificial respiration with oxygen may be necessary. Cooling measures may be needed to help to reduce fever, especially in pediatric populations.

The fatal adult dose of atropine is not known. In pediatric populations, 10 mg or less may be fatal.

11 Description

chem - 6d0fe173 dc87 4821 a764 95e01a912790 01

•  Chemical Name: Benzeneacetic acid, α-(hydroxymethyl)-, 8-methyl-8-azabicyclo[3.2.1.]oct-3-yl ester, endo –(±)-, sulfate (2:1) (salt), monohydrate.

Each mL of Atropine Sulfate Ophthalmic Solution, USP 1% contains: Active: atropine sulfate 10 mg equivalent to 8.3 mg of atropine.

Inactives: boric acid, hydroxypropyl methylcellulose, hydrochloric acid and/or sodium hydroxide may be added to adjust pH (3.5 to 6.0), and water for injection USP.

12.1 Mechanism Of Action

Atropine is a reversible antagonist of muscarine-like actions of acetylcholine and is therefore classified as an anti-muscarinic agent. Atropine is relatively selective for muscarinic receptors. Its potency at nicotinic receptors is much lower, and actions at non-muscarinic receptors are generally undetectable clinically. Atropine does not distinguish among the M1, M2, and M3 subgroups of muscarinic receptors.

The pupillary constrictor muscle depends on muscarinic cholinoceptor activation. This activation is blocked by topical atropine resulting in unopposed sympathetic dilator activity and mydriasis. Atropine also weakens the contraction of the ciliary muscle, or cycloplegia. Cycloplegia results in loss of the ability to accommodate such that the eye cannot focus for near vision.

12.2 Pharmacodynamics

The onset of action after administration of Atropine Sulfate Ophthalmic Solution, USP 1% generally occurs within minutes with maximal effect seen in hours and the effect can last multiple days [see Clinical Studies (14)].

12.3 Pharmacokinetics

In a study of healthy subjects, after topical ocular administration of 30 μL of atropine sulfate ophthalmic solution 1%, the mean (± SD) systemic bioavailability of l-hyoscyamine was reported to be approximately 64 ± 29% (range 19% to 95%) as compared to intravenous administration of atropine sulfate. The median (range) time to maximum plasma concentration (Tmax) was 19 minutes (range 3 to 60 minutes), and the mean (±SD) peak plasma concentration (Cmax) of l-hyoscyamine was 288 ± 73 pg/mL. The mean (±SD) plasma half-life was reported to be approximately 2.5 ± 0.8 hours.

In a separate study of patients undergoing ocular surgery, after topical ocular administration of 40 μL of atropine sulfate ophthalmic solution, 1%, the mean (± SD) plasma Cmax of l-hyoscyamine was 860 ± 402 pg/mL, which was observed within 8 minutes following administration.

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

Atropine sulfate was negative in the Salmonella/microsome mutagenicity test. Studies to evaluate carcinogenicity and impairment of fertility have not been conducted.

14 Clinical Studies

Topical administration of Atropine Sulfate Ophthalmic Solution, USP 1% results in mydriasis and/or cycloplegia with efficacy demonstrated in both adults and children. The maximum effect for mydriasis is achieved in about 30–40 minutes after administration, with recovery after approximately 7–10 days. The maximum effect for cycloplegia is achieved within 60–180 minutes after administration, with recovery after approximately 7–12 days.
