What is Alizer and what is it used for?

Alizer contains Serratiopeptidase 5/10 mg in tablet form. Disodium Hydrogen Citrate is an acid salt of citric acid with the chemical formula Na2C6H6O7. It is used as an antioxidant in food as well as to improve the effects of other antioxidants. It is used in:

  • Acidosis following diarrhea
  • Painful/Burning Micturition (UTI)
  • Renal Tubular Acidosis
  • Hyperuricemia
  • Kidney stones


How does it work?

Alizer is a urine alkalizer. It works by making the urine less acidic. This helps the kidneys get rid of excess uric acid, thereby preventing burning micturition, acidosis and certain types of kidney stones.


How to take Alizer?

Adults: The recommended dose is 5-10 mg 3 times per day.

Children: The drug is not used in children due to the absence of clinical data


To help prevent diarrhea and stomach upset, take each dose after a meal,


What if you miss a dose?

If you forget to take a dose of Alizer, do not worry. Just take the next dose at the usual time. Do not take a double dose to make up for a forgotten dose.

Mechanism of action:

As Urinary Alkalizer

  • When you take Alizer, it moves through your body.
  • When it reaches your liver, it is converted to bicarbonate, a usable form of base in the body.
  • This helps change the pH in your urinary tract from acidic to more basic.
  • By reducing the acidity of the urinary tract, you can experience a reduction in symptoms.


In reduction of stone formation

  • As an added bonus, citrate can bind with acidic materials in kidneys to prevent calcium oxalate stones from forming.
  • A rise in urinary pH increases the solubility of Cysteine in the urine and the ionization of Uric Acid to more soluble urate ion.
  • By maintaining alkaline urine, the actual dissolution of uric acid stones may be accomplished.


Pharmacokinetic properties:

Absorption: Reaches maximum concentration in 1-2 hours

Metabolism: Citrate is metabolized to bicarbonate in the liver and plays a role as an intermediate in the citric acid cycle

Route of elimination: Largely eliminated through hepatic metabolism with very little cleared by the kidneys

Half-life: 18-54 minutes
