Acalka belongs to the group of medications known as urinary stone solvents that serve to dissolve stones (calculi) in the urinary system.

Acalka reduces the formation of calcium oxalate crystals and the precipitation of uric acid. It increases the pH of urine, aiming to restore normal levels without causing any alteration in the body.

It is indicated for the prevention and treatment of kidney stones (calculi formation in the kidney) due to calcium oxalate and/or calcium phosphate, uric acid alone or accompanied by calcium lithiasis and hypocitraturia (decrease in citrate in the urine).

Do not take Acalka

- If you are allergic (hypersensitive) to potassium citrate or to any of the other components of this medication (listed in section 6).

- If you have kidney insufficiency (kidney disease) since the use of Acalka could produce hyperkalemia (elevated potassium levels in the blood).

- If you have a permanent alkaline urinary tract infection.

- If you have an obstruction in the urinary system (partial or total blockage of the urinary system that produces an interruption of the passage of urine through it).

- If you have hyperkalemia (elevated potassium levels in the blood).

- If you have adrenal insufficiency (disease of the adrenal glands that leads to hormonal deficiency).

- If you have respiratory alkalosis (decreased carbon dioxide levels in the blood) or metabolic alkalosis (increased bicarbonate levels in the blood).

- If you have an active peptic ulcer (stomach or duodenal ulcer).

- If you have an obstruction in the intestine (partial or total blockage of the intestine that produces an interruption of the passage of intestinal content through it).

- If you have slow gastric emptying.

- If you are taking anticholinergic medications.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Acalka.

- If you have liver insufficiency (liver disease) or a decrease in potassium excretion (elimination by the body) since the use of Acalka could produce hyperkalemia (elevated potassium levels in the blood).

- Potassium citrate is included in cera matrix tablets that allow for slow release of potassium citrate. It is likely that once the cera matrix is empty, it will be eliminated intact through the feces in a still visible form.

Use of Acalka with other medications

Inform your doctor or pharmacist that you are using, have used recently, or may need to use any other medication.

Acalka should not be taken with potassium-sparing diuretics (medications used to increase urine production without increasing potassium excretion) such as Triamtereno, Espironolactona, or Amiloride.

Use of Acalka with food and beverages

While taking Acalka, it is recommended to follow a low-sodium diet and significantly increase daily liquid consumption.

Severe hypocitraturia:

The usual dose of Acalka is 2 tablets (20 mEq of potassium citrate) 3 times a day, 30 minutes after the 3 main meals.
