Main Physico-Chemical Properties

clear colorless solution.

Pharmacotherapeutic Group

Laxatives. Enemas. Combinations. ATC Code A06A G20.

Pharmacological Properties

Pharmacodynamics

The medicinal product, when administered rectally, acts as a saline laxative. The accumulation of fluid in the lower part of the intestine causes filling and contributes to peristalsis and motility of the intestine, causing evacuation of only the rectum, sigmoid colon, and part or all of the descending colon.

Pharmacokinetics

Absorption in the colon is minimal, but it has been reported that in approximately 25% of individuals with normal kidney function after oral administration of bowel preparations containing sodium phosphate, asymptomatic hyperphosphatemia with an excess of normal phosphorus levels by 2-3 times was observed. Under normal conditions, the strongest absorption of phosphorus is observed in the small intestine, to which rectally administered preparations do not penetrate.

Clinical Characteristics

Indications

Episodic constipation.

Cases that require cleansing of the large intestine, for example, before and after surgical intervention on the large intestine, during and after childbirth, before proctoscopy, sigmoidoscopy, or colonoscopy, as well as before X-ray examination of the large intestine.

Contraindications

Increased sensitivity to the active substances or to any other substance that is part of the medicinal product.

States in which the ability to absorb or decrease the ability to evacuate is increased, for example, when there is intestinal obstruction or decreased peristalsis:

• suspected intestinal obstruction;
• paralytic intestinal obstruction;
• anorectal stenosis;
• atresia / narrowing / incomplete opening of the anus;
• narrowing of the rectum;
• enlargement of the colon (megacolon);
• Hirschsprung's disease;
• ileostomy.

Undiagnosed pathology of the gastrointestinal tract, for example:

• symptoms indicating appendicitis, perforation / damage or intestinal obstruction; active inflammatory disease of the large intestine (e.g., Crohn's disease or ulcerative colitis);
• undetected rectal bleeding.

Stagnant and symptomatic heart failure.

Dehydration.

Childhood.

Renal failure of moderate or severe degree.

Uncontrolled arterial hypertension.

Do not use simultaneously with other medicinal products containing sodium phosphate.

Interaction with Other Medicinal Products and Other Types of Interactions

Use with caution in patients who are taking calcium channel blockers, diuretics, lithium preparations, or other preparations that can cause dehydration or affect electrolyte levels, as there is a risk of developing hyperphosphatemia, hypocalcemia, hypokalemia, hypernatremic dehydration, and acidosis.

Do not use simultaneously with other medicinal products containing sodium phosphate (see section "Contraindications").

Since hypernatremia is associated with a low level of lithium, the simultaneous use of the medicinal product and lithium therapy may cause a decrease in the level of lithium in the blood serum and a decrease in its effectiveness.

Special Warnings and Precautions for Use

Do not use the medicinal product without a doctor's prescription if there is nausea, vomiting, or abdominal pain.

In case of bowel movements after taking this medicinal product, it is necessary to drink plenty of fluids to prevent dehydration, especially in diseases that can lead to dehydration, or when taking medicinal products that can reduce the rate of glomerular filtration, such as diuretics, angiotensin-converting enzyme inhibitors (ACE inhibitors, e.g., enalapril, ramipril, lisinopril), angiotensin receptor blockers (ARBs, e.g., losartan, candesartan, eprosartan, irbesartan, olmesartan, telmisartan, valsartan), or nonsteroidal anti-inflammatory drugs (NSAIDs).

Since the medicinal product contains sodium phosphates, there is a risk of increased concentrations of sodium and phosphate, as well as decreased concentrations of calcium and potassium in the blood serum, which can lead to hypernatremia, hyperphosphatemia, hypocalcemia, and hypokalemia with clinical signs similar to tetany and renal failure.

Electrolyte imbalance is especially dangerous for children who suffer from megacolon or any other disease in which fluid retention is observed, and for patients with concomitant diseases.

For this reason, the medicinal product should be prescribed with caution to elderly or exhausted patients; patients being treated with lithium preparations; patients with ascites, heart disease, changes in the rectal mucosa (ulcers, cracks), colostomy, who use diuretics or other medicinal products that affect electrolyte balance, preparations that can prolong the QT interval (e.g., amiodarone, arsenic trioxide, astemizole, azithromycin, erythromycin, clarithromycin, chlorpromazine, cisapride, citalopram, domperidone, terfenadine, procainamide), or patients with existing electrolyte imbalance, such as hypocalcemia, hypokalemia, hyperphosphatemia, or hypernatremia. Use with caution in patients who are taking preparations that affect renal perfusion, kidney function, or hydration. In case of suspected electrolyte imbalance and a history of hypophosphatemia in patients, monitoring of electrolyte levels before and after administration of the preparation is necessary.

The medicinal product should be used with caution in patients with impaired renal function and only if the benefit of use outweighs the risk of hyperphosphatemia.

Repeated and prolonged use of the medicinal product is not recommended, as it can cause habituation. Introduction of more than one enema within 24 hours can be harmful. If there are no doctor's instructions, the medicinal product should not be used for more than 6 days in a row.

Before using the medicinal product, it is necessary to familiarize yourself with the instructions for medical use, in particular with the rules for its administration (see section "Method of Administration and Dosage"). The tip of the bottle should not be inserted into the rectum if it has not been previously lubricated with petroleum jelly. Patients should be warned to stop administration in case of feeling resistance, as efforts during administration can cause local damage. Rectal bleeding after administration of the medicinal product may indicate a serious condition. In this case, further administration of the medicinal product should be stopped immediately, and a doctor should be consulted.

Usually, bowel movements occur approximately 5 minutes after administration of the medicinal product, so retention of the enema for more than 5 minutes is not recommended. If after administration of the medicinal product bowel movements do not occur or if the retention time lasts more than 10 minutes, serious side effects may occur. In this case, further administration of the medicinal product should be stopped, and a doctor should be consulted, who will decide on the appointment of laboratory tests to detect possible deviations in electrolyte levels and minimize the risk of developing severe hyperphosphatemia.

This medicinal product contains 80 mg of benzalkonium chloride per dose (118 ml), which can cause irritation and skin reactions.

"Freeflo enema" is a solution for rectal administration.

DO NOT SWALLOW.
