71% of patients stopped making cystine stones
THIOLA may help manage recurring cystine stones
THIOLA was studied in 66 patients with cystinuria and a history of forming stones. In 17 patients without prior d-penicillamine therapy:
- 71% stopped making stones
- 94% reduced the rate of making stones
Increased fluid intake, urine alkalization, diet modifications, and THIOLA EC together may help prevent stone formation
THIOLA EC works fast to help lower cystine levels
- Keeping your cystine level below its solubility limit (generally <250 mg/L) is important in managing cystinuria.
- THIOLA EC starts to work on the first day to lower cystine levels.
- THIOLA EC contains the active ingredient, tiopronin, in a delayed-release formulation.
Watch this video to see how THIOLA EC works within the kidneys to lower cystine levels.
In the small tubes of the kidney
In cystinuria
Cystine does not dissolve well in the urine. High levels of cystine lead to cystine stone formation.
With THIOLA EC
The active ingredient in THIOLA EC, tiopronin, attaches to cystine to become a new compound called tiopronin-cysteine, which dissolves more easily.

It is important to remember to continue drinking more water, reducing your protein and sodium intake, and taking medications to adjust the pH of your urine while taking THIOLA EC. Once you start treatment, your doctor will schedule regular visits and ask you to perform 24-hour urine collections to monitor your cystine level.
Your doctor may discontinue THIOLA EC if you develop high amounts of protein in your urine and will monitor your urine and kidneys. Your doctor may consider restarting treatment at a lower dose once your urinary protein level is no longer a concern.
After being on THIOLA EC for 1 month, your doctor will ask you to perform a 24-hour urine test to evaluate your cystine level and determine necessary dosing adjustments.
Your doctor should ask you to perform a 24-hour urine test every 3 months thereafter to continue monitoring your cystine level.
Take an active role in your cystine stone prevention by sticking to your treatment plan and regularly monitoring your cystine level.
