Longidaza: when and why to take it

pharmachologic effect

The drug is highly active and is a macromolecular complex of the proteolytic enzyme hyaluronidase. When taken, it has the following effects:

relieves inflammation;
eliminates swelling;
promotes activation of humoral immunity;
antifibrotic.

Longidaza improves tissue nutrition, eliminates adhesions, contractures, accelerates the resorption of bruises and hematomas, and also increases joint mobility.

The drug works best in the initial stages of the disease, preventing its progression and the development of complications.

Longidaza also enhances the effect of local anesthetics, increasing their bioavailability.

The medication is characterized by incredibly low toxicity and the absence of negative effects on the body.

Longidaza®

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

Prolongation of the action of the enzyme is achieved by covalent binding of the enzyme to a physiologically active polymer carrier (azoximer). Longidase® exhibits antifibrotic properties, weakens the course of the acute phase of inflammation, regulates (increases or decreases depending on the initial level) the synthesis of inflammatory mediators (interleukin-1 and tumor necrosis factor - alpha), increases the humoral immune response and the body's resistance to infection.

The pronounced antifibrotic properties of Longidase are ensured by the conjugation of hyaluronidase with a carrier, which significantly increases the resistance of the enzyme to denaturing influences and the action of inhibitors: the enzymatic activity of Longidase is maintained when heated to 37 ° C for 20 days, while native hyaluronidase loses its activity under the same conditions during the day. The Longidaza® preparation ensures the simultaneous local presence of the enzyme hyaluronidase and a carrier capable of binding enzyme inhibitors and stimulators of collagen synthesis (iron, copper ions, heparin, etc.) released during hydrolysis of matrix components. Thanks to these properties, Longidaza® not only has the ability to depolymerize the connective tissue matrix in fibrogranulomatous formations, but also suppress the reverse regulatory reaction aimed at the synthesis of connective tissue components.

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 and metal ions decreases, the permeability of tissue barriers temporarily increases, fluid movement in the intercellular space is facilitated, and the elasticity of connective tissue increases. , which manifests itself in a decrease in tissue swelling, flattening of scars, an increase in the range of motion of joints, a decrease in contractures and prevention of their formation, and a decrease in adhesions. Biochemical, immunological, histological and electron microscopic studies have proven that Longidaza® does not damage normal connective tissue, but causes destruction of connective tissue altered in composition and structure in the area of fibrosis.

Longidaza® does not have mutagenic, embryotoxic, teratogenic or carcinogenic effects.

The drug was well tolerated by patients; no local or general allergic reactions were noted.
The use of Longidase in therapeutic doses during or after surgical treatment does not cause worsening of the postoperative period or progression of the infectious process; does not slow down bone tissue recovery.

Pharmacodynamics and pharmacokinetics

When the drug is administered by injection, it immediately enters the bloodstream, due to which the maximum concentration of the active substance is achieved in less than half an hour. The bioavailability of Longidase is about 90 percent, and it penetrates into any tissue of the human body. The half-life in this case is one day, and the drug is completely eliminated only after 5 days. It is excreted mainly by the kidneys, partly by the intestines.

When using suppositories, the maximum concentration is achieved only after 60 minutes. This dosage form has 70% bioavailability, and its half-life is extended to 2-3 days.

Indications and contraindications for taking Longidaza

This drug is prescribed not only for the treatment, but also for the prevention of many diseases with connective tissue hyperplasia syndrome. It is used in the following medical fields:

Gynecology: for inflammatory diseases of the genital organs, as well as for adhesions in the pelvic area.
Pulmonology: fibrosing and sclerosing diseases of the lungs and respiratory tract, tuberculosis.
Urology: chronic prostatitis and complicated cystitis.
Surgery: prevention of adhesions after extensive abdominal surgery.
Dermatovenereology: scleroderma, rough, keloid, disfiguring scars after various skin pathological processes.

There are also contraindications to the use of Longidase and, despite the low toxicity of the drug, there are quite a few of them:

Individual intolerance to hyaluronidase.
Oncological diseases.
CKD.
Bleeding and hemorrhage.
Age under 18 years.
Infections during the acute period of the disease.

Longidaza por d/in 3000IU N5 (Petrovax)

A drug with proteolytic activity. It has enzymatic proteolytic (hyaluronidase) activity of prolonged action, immunomodulatory, chelating, antioxidant and anti-inflammatory effects. Prolongation of the action of the drug is carried out due to the covalent binding of the enzyme to a physiologically active high-molecular carrier (activated derivative of poly-1.4-ethylenepiperazine N-oxide), which has its own pharmacological activity : has an immunomodulatory, detoxifying and antioxidant effect. The presence of a covalent bond significantly increases the enzyme’s resistance to denaturing influences and the influence of inhibitors. The enzymatic activity of Longidase is maintained when heated to 37°C for 20 days, while native hyaluronidase under the same conditions loses its activity within 24 hours. The covalent bond ensures the simultaneous local presence of a hydrolytic enzyme and a carrier capable of binding released enzyme inhibitors and stimulants collagen synthesis (iron, copper ions, heparin). Thanks to these properties, Longidase not only has the ability to depolymerize the connective tissue matrix in fibrous granulomatous formations, but also suppress the reverse regulatory reaction aimed at the synthesis of connective tissue components. 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 C 1 acetylglucosamine and C 4 glucuronic or induronic acids) under the influence of hyaluronidase, glycosaminoglycans lose their basic properties (viscosity, ability to bind water, metal ions). The formation of collagen proteins into fibers is also hampered, the permeability of tissue barriers increases, the movement of fluid in the intercellular space is facilitated, and the elasticity of connective tissue increases. The action of the drug leads to a decrease in tissue swelling, flattening of scars, an increase in the range of motion of joints, a decrease in contractures and adhesions and the prevention of their formation. The drug reduces the manifestations of the acute phase of the inflammatory process, regulates (increases or decreases depending on the initial level) the synthesis of inflammatory mediators (interleukin -1 and tumor necrosis factor), increases the body's resistance to infection and the humoral immune response. Longidase does not have antigenic properties, mitogenic, polyclonal activity, does not have allergenic, mutagenic, embryotoxic, teratogenic and carcinogenic effects.
