CYSTADROPS (sys-tah-drops) is a prescription eye drop that reduces cystine crystals in the corneathe front layer of the eye with practical, 4 times a day dosing.
CYSTADROPS was approved by the Food and Drug Administration based on studies that demonstrated safety and effectiveness in people with cystinosis.
One study showed a 12% decrease in cystine crystals in the cornea after 30 days of treatment and a 40% decrease in cystine crystals in the cornea after 90 days.
A longer-term study showed a 30% decrease in cystine crystals in the cornea that was maintained for 5 years.
The active ingredient in CYSTADROPS, cysteamine, enters the lysosomesLysosomes are the organelles within the cells in your body that act as cell digestive system. Lysosomes break apart amino acids such as cystine of cells in the cornea. Once inside, it breaks apart cystine, which can then be transported out of the lysosomes. As a result, the build-up of corneal cystine crystals decreases over time with continuous treatment.
CYSTADROPS is a viscous formulation that appears as a thick liquid solution applied directly to the eye in order to reach the cells in the cornea.
Talk to your doctor if you are experiencing any side effects due to treatment.
Ongoing, continuous use of cystine-depleting eyedrops may reduce the build-up of cystine crystals in the cornea. As shown in the studies, corneal cystine crystals were reduced over time when CYSTADROPS was used continuously.
CYSTADROPS (cysteamine ophthalmic solution) 0.37% is a cystine-depleting agent indicated for the treatment of corneal cystine crystal deposits in adults and children with cystinosis.
