Clinical Pharmacology


Longidaza® has hyaluronidase (enzymatic) activity of prolonged action, chelating, antioxidant, immunomodulatory and moderately pronounced anti-inflammatory properties.

The prolongation of the enzyme action is achieved by covalent binding of the enzyme with a physiologically active polymeric carrier (azoxymer). Longidaza® shows anti-fibrotic properties, weakens the acute phase of inflammation, regulates (increases or decreases depending on the initial level) synthesis of inflammatory mediators (interleukin-1 and tumor necrosis factor - alpha), increases the humoral immune response and resistance of the organism to infection.

The pronounced anti-fibrotic properties of Longidaza are provided by conjugation of hyaluronidase with a carrier, which significantly increases the resistance of the enzyme to denaturing effects and to the action of inhibitors: Longididase enzymatic activity is maintained when heated to 37 ° C for 20 days, while native hyaluronidase loses its activity under the same conditions during the day. In the preparation of Longidaza, the simultaneous local presence of the enzyme hyaluronidase and a carrier is provided that is capable of binding enzyme inhibitors and stimulators of collagen synthesis (iron, copper, heparin, etc.) released during hydrolysis of the matrix components. Due to these properties, Longidase® not only has the ability to depolymerize the matrix of connective tissue in fibrous granulomatous masses, but also to suppress the reverse regulatory response, aimed at the synthesis of components of the connective tissue.

The specific substrate of testicular hyaluronidase is glycosaminoglycans (hyaluronic acid, chondroitin, chondroitin-4-sulfate, chondroitin-6-sulfate), which form the basis of the connective tissue matrix. As a result of depolymerization (breaking the bond between C1 acetylglucosamine and C4 glucuronic or induronic acids), glycosaminoglycans change their basic properties: viscosity decreases, the ability to bind water decreases, metal ions temporarily increase the permeability of tissue barriers, facilitates the movement of fluid in the intercellular space, increases the elasticity of connective tissue , which is manifested in a decrease in swelling of the tissue, flattening of scars, an increase in the volume of movement of the joints, a decrease in contractures and ezhdenii their formation, reduction of adhesions. Biochemical, immunological, histological and electron microscopic studies have shown that Longidase® does not damage normal connective tissue, but causes destruction of the composition and structure of the connective tissue in the area of ​​fibrosis.

Longidis® does not have mutagenic, embryotoxic, teratogenic and carcinogenic effects.

The drug is well tolerated by patients, there are no local and general allergic reactions.

The use of Longidaza in therapeutic doses during or after surgical treatment does not cause deterioration of the postoperative period or progression of the infectious process; does not slow down the recovery of bone tissue.


An experimental study of pharmacokinetics has made it possible to establish that when administered rectally, the drug Longidase® is characterized by a high rate of distribution in the body, is well absorbed into the systemic circulation and reaches its maximum concentration in the blood after 1 hour. The half-distribution period is about 0.5 hours, the half-elimination period is from 42 to 84 hours. Excreted mainly by the kidneys.

The drug penetrates into all organs and tissues, including it passes through the blood-brain and blood-brain barriers. Established the absence of tissue cumulation.

The bioavailability of the drug Longidase® with rectal administration is high: about 90%.


Adults and adolescents over 12 years of age in the form of monotherapy and as part of the complex therapy of diseases involving connective tissue hyperplasia, including against the background of the inflammatory process:

  • in urology: chronic prostatitis, interstitial cystitis, strictures of the urethra and ureters, Peyronie's disease, the initial stage of benign prostatic hyperplasia, prevention of scar formation and strictures after surgical interventions on the urethra, bladder, ureters;
  • in gynecology: adhesions (prevention and treatment) in the small pelvis for chronic inflammatory diseases of the internal genital organs, after gynecological manipulations, including artificial abortions, previous surgical interventions on the pelvic organs; intrauterine synechia, tubal-peritoneal infertility, chronic endomyometritis;
  • in dermatovenerology: limited scleroderma, prevention of fibrous complications of sexually transmitted infections;
  • in surgery: prevention and treatment of adhesions after surgery on the abdominal organs; long-term non-healing wounds;
  • in pulmonology and phthisiology: pneumofibrosis, siderosis, tuberculosis (cavernous-fibrous, infiltrative, tuberculoma), interstitial pneumonia, fibrosing alveolitis, pleurisy;
  • to increase the bioavailability of antibiotic therapy in urology, gynecology, dermatology, surgery, pulmonology, etc.
