Indication

CYSTARAN® (CYSTEAMINE OPHTHALMIC SOLUTION) 0.44% is a cystine-depleting agent indicated for the treatment of corneal cystine crystal accumulation in patients with cystinosis.

Mechanism of Action

Cysteamine, the active ingredient in CYSTARAN, is an aminothiol that depletes lysosomal cystine, preventing buildup of cystine crystals in bodily tissues.1,2

Cystinotic Lysosome

Cystinotic Lysosome Treated
with Cysteamine

cysteamine mechanism of action animation
  • Within lysosomes, cysteamine interacts with cystine to form cysteine and cysteine–cysteamine mixed disulfide1,2
  • These substances can pass through the lysosomal membrane and be eliminated from the cell1,2

Dosage and Administration

Storing CYSTARAN1

  • Patients should be advised to store bottles in the freezer in the original carton
  • Each week, one new bottle should be removed from the freezer
  • Patients should be advised to allow the bottle to thaw completely (approximately 24 hours) prior to use

Administration of CYSTARAN

  • CYSTARAN is supplied in a 15-mL bottle of sterile ophthalmic solution. Each mL contains 6.5 mg cysteamine hydrochloride equivalent to 4.4 mg of cysteamine (0.44%)
  • Instill one drop of CYSTARAN in each eye, every waking hour
  • Do not touch dropper tip to any surface, as this may contaminate the solution

Warnings and Precautions

Contamination of Tip and Solution

To minimize contaminating the dropper tip and solution, care should be taken not to touch the eyelids or surrounding areas with the dropper tip of the bottle. Keep bottle tightly closed when not in use1

Benign Intracranial Hypertension

There have been reports of benign intracranial hypertension (or pseudotumor cerebri) associated with oral cysteamine treatment that has resolved with the addition of diuretic therapy. There have also been reports associated with ophthalmic use of cysteamine; however, all of these patients were on concurrent oral cysteamine1

Use with Contact Lenses

CYSTARAN contains benzalkonium chloride, which may be absorbed by soft contact lenses. Contact lenses should be removed prior to application of solution and may be reinserted 15 minutes following its administration1

CYSTARAN is for topical ophthalmic use only.
