The composition and form of issue:

Lyophilisate for preparation of solution for intramuscular and subcutaneous injection. 1 ampoule or flask contains:

longidasa with hyaluronidase activity of 1500 IU

3000 IU

auxiliary substances: mannitol — up to 15 or 20 mg 

in ampoules or vials made of neutral glass, in a contour acheikova package 5 vials or 5 vials in a cardboard pack 1 pack.

Description pharmaceutical form:

Porous mass of white or white with a yellowish or brownish color, hygroscopic.

Pharmacokinetics:

For parenteral administration the active substance is rapidly absorbed into the systemic circulation and reaches the Cmax in the blood after 20-25 min, the highest speed of distribution in the body. T1/2 about 0, 5 h, T1/2 in the/m introduction — 36 h, with p/C — about 45 h. the Apparent Vd is 0, 43 l/kg. Conjugation does not reduce the high bioavailability of the enzyme (bioavailability 90%).

Active substance penetrates into all organs and tissues, including across the BBB and gematoentsefalichesky barrier.

In the body of the hyaluronidase undergoes hydrolysis, and the media breaks down to low molecular weight compounds (oligomers), which are excreted primarily through the kidneys in two phases. During the first day through the kidneys is excreted 45-50% , through the intestines — not more than 3%. Further, the clearance rate slows down to 4-5-th day the drug is excreted completely.

Description pharmacological action:

Largedataset a conjugate proteolytic enzyme with hyaluronidase macromolecular carrier from the group of derivatives of N-oxide poly-1, 4-etilenpiperazina. Longidasa has all spectrum of pharmacological properties of drugs with hyaluronidase activity. A specific substrate of hyaluronidase are glycosaminoglycans (hyaluronic acid, chondroitin, chondroitin-4-sulfate, chondroitin-6-sulfate) — cementing substance of connective tissue.

As a result of the hydrolysis (depolymerization) decreases the viscosity of glycosaminoglycans, the ability to bind water and ions of metals. As a result, increases the permeability of tissues, improves trophism, reduce swelling, dissolve hematomas, improves elasticity rubtsovoizmenennah sites, eliminate contractures and adhesions, increase joint mobility. The effect is most pronounced in the initial stages of the pathological process.

The clinical effect of the drug Longidasa significantly higher than the effect of native hyaluronidase. Conjugation increases the stability of enzyme the effect of temperature and inhibitors, increases its activity and leads to prolongation of the action. The enzymatic activity of the drug Longidasa is saved when heated to 37 °C for 20 days, while the native hyaluronidase in the same conditions loses its activity during the day. In preparation Longidase saved and pharmacological properties of the medium with gelatinosa, antioxidant, anti-inflammatory and immunomodulatory activity. Longidasa able to bind the liberated during the hydrolysis of glycosaminoglycans iron ions — the promoters of free radical reactions, inhibitors of hyaluronidase and stimulators of collagen synthesis and thereby suppress the reverse reaction aimed at the synthesis of components of connective tissue.

Polytropic properties of the drug Longidasa implemented in the expressed protivopoloznom action, it has been experimentally proven biochemical, histological and electron microscopic studies on the model of pulmonary fibrosis.

Drug Longidasa adjusts (increases or reduces depending on the source level) the synthesis of inflammatory mediators (IL-1 and tumor necrosis factor alpha) may be reduced during the acute phase of inflammation, increase humoral immune response and resistance of organism to infection. These properties allow the use of the drug Longidasa during or after surgical treatment for prevention of rough scarring and adhesions.

The use of the drug Longidasa in therapeutic doses during or after surgery does not cause deterioration in the postoperative period or progression of the infectious process does not slow bone recovery.

Longidasa with joint p/to or/m introduction increases the absorption of drugs, accelerates the anesthesia with the injection of local anesthetics. Longidasa applies to practically non-toxic compounds, does not disturb normal functioning of the immune system, has no effect on the reproductive function of males and females of rats on pre - and postnatal development of the offspring, is not mutagenic and carcinogenic. Experimentally proved that the drug reduced Longidasa irritating and allergenic properties of the enzyme hyaluronidase. At therapeutic doses, Longidasa well tolerated by patients.
