Carbachol and Brimonidine Tartrate

INDICATIONS AND USAGE YUVEZZI™ is indicated for the treatment of presbyopia in adults. YUVEZZI is a combination of carbachol, a cholinergic agonist, and brimonidine, an alpha-adrenergic receptor agonist, indicated for the treatment of presbyopia in adults. ( 1 )

DOSAGE AND ADMINISTRATION Instill one drop in each eye once daily. ( 2.1 ) 2.1 Recommended Dosage The recommended dosage of YUVEZZI is one drop in each eye once daily. 2.2 Administration Instructions Remove contact lenses prior to instillation of YUVEZZI. Wait 10 minutes after dosing before reinserting contact lenses. If more than one topical ophthalmic medication is being used, the medicines must be administered at least 5 minutes apart. One single-dose vial can be used to dose both eyes. Discard the open single-dose vial and any remaining contents immediately after use.

WARNINGS AND PRECAUTIONS Blurred Vision : Advise patients not to drive or operate machinery if vision is not clear (e.g., blurred vision). Exercise caution in night driving and other hazardous activities in poor illumination. ( 5.1 ) Risk of Retinal Detachment : Rare cases of retinal tear and detachment have been reported with miotics. Individuals with preexisting retinal disease are at increased risk. Therefore, examination of the retina is advised in all patients prior to initiation of therapy. Patients should be advised to seek immediate medical care with sudden onset of flashes of lights, floaters, or vision loss. ( 5.2 ) Iritis : Caution is advised in patients with iritis. ( 5.3 ) Potentiation of Vascular Insufficiency : Use with caution in patients with depression, cerebral or coronary insufficiency, Raynaud's phenomenon, orthostatic hypotension, or thromboangiitis obliterans. ( 5.4 ) 5.1 Blurred Vision Miotics may cause accommodative spasm. Advise patients to not drive or operate machinery if vision is not clear (e.g., blurred vision). In addition, patients may experience temporary dim or dark vision with miotics. Advise patients to exercise caution in night driving and other hazardous activities in poor illumination. 5.2 Risk of Retinal Detachment Rare cases of retinal tear and detachment have been reported with miotics. Individuals with pre-existing retinal disease are at increased risk. Examination of the retina is advised in all patients prior to the initiation of therapy. Advise patients to seek immediate medical care with sudden onset of flashes of lights, floaters, or vision loss. 5.3 Iritis Sequelae of ocular inflammation, i.e., adhesions (synechiae) between the iris and the lens, may be exacerbated with miotic use, therefore, YUVEZZI is not recommended to be used when iritis is present. 5.4 Potentiation of Vascular Insufficiency YUVEZZI may potentiate syndromes associated with vascular insufficiency. YUVEZZI should be used with caution in patients with depression, cerebral or coronary insufficiency, Raynaud's phenomenon, orthostatic hypotension, or thromboangiitis obliterans. 5.5 Potential for Eye Injury or Contamination To prevent eye injury or contamination, avoid touching the single-dose vial to the eye, eyelids, or to any other surface.

CONTRAINDICATIONS YUVEZZI is contraindicated in patients with known hypersensitivity to the active ingredients or to any of the excipients. Hypersensitivity. ( 4 )

DRUG INTERACTIONS Antihypertensives/cardiac glycosides may lower blood pressure. ( 7.1 ) Use with CNS depressants may result in an additive or potentiating effect. ( 7.2 ) Tricyclic antidepressants may potentially blunt the hypotensive effect of systemic clonidine. ( 7.3 ) Monoamine oxidase inhibitors may result in increased hypotension. ( 7.4 ) 7.1 Antihypertensives/Cardiac Glycosides Because brimonidine tartrate, a component of YUVEZZI, may reduce blood pressure, caution in using drugs such as antihypertensives and/or cardiac glycosides with YUVEZZI is advised. 7.2 CNS Depressants Although specific drug interaction studies have not been conducted with YUVEZZI, the possibility of an additive or potentiating effect with central nervous system (CNS) depressants (alcohol, opiates, barbiturates, sedatives, or anesthetics) should be considered. 7.3 Tricyclic Antidepressants Tricyclic antidepressants have been reported to blunt the hypotensive effect of systemic clonidine. It is not known whether the concurrent use of these agents with YUVEZZI in humans can lead to resulting interference with pupil constriction effects. Caution is advised in patients taking tricyclic antidepressants, which can affect the metabolism and uptake of circulating amines. 7.4 Monoamine Oxidase Inhibitors Monoamine oxidase (MAO) inhibitors may theoretically interfere with the metabolism of brimonidine tartrate and potentially result in an increased systemic side effect such as hypotension. Caution is advised in patients taking MAO inhibitors which can affect the metabolism and uptake of circulating amines.

ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in labeling: Hypersensitivity [see Contraindications (4) ] Most common adverse reactions (incidence >5%) are eye pain upon instillation, visual impairment, eye irritation upon instillation, and headache.

YUVEZZI was evaluated in 536 patients with presbyopia in two randomized, double-masked, controlled studies. BRIO™ I (NCT05270863) was a single-dose crossover study in which 178 patients received YUVEZZI. BRIO II (NCT05135286) included 358 patients who received YUVEZZI in the long-term safety portion of the study (up to 12 months duration, including a 6-month open-label extension). Adverse reactions reported in > 5% to 7% of participants were eye pain upon instillation and visual impairment. Adverse reactions reported in > 10% to 16% of participants were eye irritation upon instillation and headache. The majority of adverse events were mild, transient, and self-resolving.

Mechanism of Action The proposed mechanism of action of this fixed-dose combination of carbachol and brimonidine in presbyopia is pupillary constriction and the creation of a pinhole effect that improves near visual acuity and depth of focus. Carbachol is a cholinergic agent which produces constriction of the iris sphincter and ciliary body. Brimonidine tartrate, an alpha-adrenergic agonist, blocks contraction of the iris dilator muscle and relaxes tonic contraction of the ciliary muscle, enhancing selectivity for the pupil and increasing bioavailability of carbachol in the aqueous humor.
