The following adverse reactions are described below and elsewhere in the labeling:
- Photophobia and Blurred Vision [see WARNINGS AND PRECAUTIONS]
- Elevation in Blood Pressure [see WARNINGS AND PRECAUTIONS]
- Increased Adverse Drug Reaction Susceptibility with Certain Central Nervous System Conditions [see WARNINGS AND PRECAUTIONS]
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.
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.
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 mucus membranes; drowsiness; restlessness, irritability or delirium from stimulation of the central nervous system; tachycardia; flushed skin of the face and neck.
Monoamine Oxidase Inhibitors
Included as part of the "PRECAUTIONS" Section
Photophobia And Blurred Vision
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, 1%.
Increased Adverse Drug Reaction Susceptibility With Certain Central Nervous System Conditions
Individuals with Down syndrome, spastic paralysis, or brain damage are particularly susceptible to central nervous system disturbances, cardiopulmonary, and gastrointestinal toxicity from systemic absorption of atropine.
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.
Use In Specific Populations
There are no adequate and well-controlled studies with ISOPTO® Atropine 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]. ISOPTO® Atropine 1% should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus.
There is no information to inform risk regarding the presence of atropine in human milk following ocular administration of ISOPTO® Atropine 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 ISOPTO® Atropine 1% and any potential adverse effects on the breastfed child from ISOPTO® Atropine 1%.
Due to the potential for systemic absorption of atropine sulfate ophthalmic solution the use of ISOPTO® Atropine 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.
No overall differences in safety or effectiveness have been observed between elderly and adult patients.
In the event of accidental ingestion or toxic overdosage with atropine sulfate ophthalmic solution 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 pediatric and adult doses of atropine are not known.
Atropine sulfate ophthalmic solution 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.
Mechanism Of Action
Atropine acts as a competitive antagonist of the parasympathetic (and sympathetic) acetylcholine muscarinic receptors. Topical atropine on the eye induces mydriasis by inhibiting contraction of the circular pupillary sphincter muscle normally stimulated by acetylcholine. This inhibition allows the countering radial pupillary dilator muscle to contract which results in dilation of the pupil. Additionally, atropine induces cycloplegia by paralysis of the ciliary muscle which controls accommodation while viewing objects.
The onset of action after administration of ISOPTO Atropine 1% generally occurs in minutes with maximal effect seen in hours and the effect can last multiple days [see Clinical Studies].
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 mean (± SD) time to maximum plasma concentration (Tmax) was approximately 28 ± 27 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.
Topical administration of ISOPTO® Atropine 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.
- Advise patients not to drive or engage in other hazardous activities while pupils are dilated.
- Advise patient that they may experience blurry vision and sensitivity to light and should protect their eyes in bright illumination during dilation. These effects may last up to a couple weeks.
- Advise patients that they may experience drowsiness.
- Advise patients not to touch the dispenser tip to any surface, as this may contaminate the solution.
