Overview of Лидаза

What is Lydasa?

Lydasa is a pharmaceutical preparation containing the enzyme hyaluronidase. This enzyme is naturally occurring and plays a critical role in the breakdown of hyaluronic acid, a primary component of the interstitial matrix in connective tissues.

Mechanism of Action

The primary function of Lydasa is to decrease the viscosity of hyaluronic acid. By breaking down this complex polysaccharide, the drug increases the permeability of tissues and improves the movement of fluids between cells. This action leads to several physiological effects:

  • Reduction of Edema: It facilitates the drainage of fluid from congested areas.
  • Softening of Tissues: It helps in the breakdown of dense connective structures, such as scars or adhesions.
  • Improved Absorption: It enhances the movement of other substances through the tissue layers, potentially increasing the distribution of co-administered fluids.

Pharmacological Properties

When hyaluronidase is introduced into the body, it acts locally to temporarily reduce the barrier function of the connective tissue. This effect is reversible; once the enzyme is no longer active, the concentration of hyaluronic acid naturally restores itself, and the normal permeability of the tissue returns.

Lydasa is primarily utilized in clinical settings to address conditions characterized by excessive connective tissue growth or restricted fluid movement. Its ability to modify the physical state of the extracellular matrix makes it a versatile tool in managing various musculoskeletal and dermatological concerns.

Overdose and Emergency Response

Overdose and When to Seek Help

The official regulatory description of a Hyaluronidase overdose focuses on a documented cluster of signs that mandate immediate clinical attention. Overdose manifestations are classified into local effects and systemic symptoms of toxicity.

Documented Signs of Toxicity Overdose presentations include specific local effects at the site of administration, such as swelling (edema), hives (urticaria), and pronounced redness (erythema). Systemic manifestations of toxicity are noted in official prescribing information, including general symptoms such as chills, nausea, vomiting, and dizziness.

Severe Manifestations and Required Action Toxicity is further defined by signs of systemic cardiovascular stress. These severe outcomes include tachycardia (rapid heart rate) and a significant drop in blood pressure (hypotension). The presence of these systemic signs officially classifies the event as one requiring urgent intervention.

When any documented symptoms of toxicity are recognized, the enzyme preparation must be discontinued immediately. The official regulatory guidance states that supportive measures must be initiated without delay. Management is strictly limited to symptomatic and supportive treatment, as a specific antidote is not documented. The emergence of documented cardiovascular symptoms necessitates immediate medical assistance.

Therapeutic Uses of Лидаза

What Лидаза Treats: Main Uses and Benefits

Core Therapeutic Support

The medication is applied across domains where additional symptomatic support is needed in specific clinical scenarios. It is utilized to assist with various symptom-driven clinical presentations where tissue permeability is a factor.

This enzyme plays a role in managing symptoms related to local anesthetic spread and may assist with rapid, widespread distribution, which is relevant in contexts marked by increased discomfort or tension. This supports patients who require fluid management by assisting with the comfortable absorption of necessary subcutaneous fluids, a helpful consideration in patient groups like small children and older adults where alternate methods are not easily available.

Symptom Management and Functional Benefit

The medication is commonly used across conditions presenting with localized discomfort, including situations requiring subcutaneous fluid administration, as an aid in subcutaneous urography, and may be part of symptomatic management to support the spread of co-administered injected drugs. The medication is applied in clinical settings that involve acute or unstable symptom patterns, offering supportive relief when symptoms of localized post-injection injury become temporarily overwhelming, such as with accidental drug leakage (extravasation) or the need to manage certain dermal filler materials in acute situations. Furthermore, it is relevant for easing challenging symptoms associated with excessive fibrous tissue, such as mature scars or localized sclerotic conditions. The primary benefit sought often contributes to improved tissue flexibility and assists with the effective and comfortable delivery of localized treatments.


Quick Fact: Relief for Tissue Tension and Discomfort The medication is commonly used to help manage symptom clusters associated with tissue hardness, localized swelling, and restricted movement, providing support that helps ease the overall symptom burden during symptomatic periods.

Eligibility and Restrictions for Use

Official Population Eligibility and Restrictions

The regulatory information for Лидаза (Hyaluronidase) strictly defines the populations permitted to use the medicine and those who are excluded. The most crucial non-eligibility rule is the absolute contraindication for any patient with a known hypersensitivity or allergy to hyaluronidase or any excipient in the formulation.

Use is also strictly prohibited at certain local sites. The medicine must not be injected into or around an infected or acutely inflamed area due to the potential risk of spreading the condition. It is also prohibited from being used to treat bites or stings and must not be applied directly to the cornea.

Eligibility for the geriatric population is generally unrestricted. In contrast, use in pediatric patients is highly regulated: specific maximum volume and rate limits must be followed for infants, premature infants, and children under three years old. For pregnant women, administration is conditional, permitted only if clearly needed, and caution is advised for nursing mothers as excretion into human milk is unknown.

What should I know about interactions with other medicines?

Interactions with other medicines and products

The interaction profile for Лидаза (Hyaluronidase) is defined by its function as a tissue permeability modifier, leading primarily to local pharmacodynamic interactions rather than systemic metabolic effects. Official regulatory documents outline two core interaction types: enhancement of absorption and mandatory administration restrictions.

Pharmacodynamic Interaction Patterns

Co-administration with the enzyme results in a pharmacodynamic enhancement of local dispersion, which leads to increased systemic absorption and exposure of other medicinal products. This effect is specifically documented for substances intended for subcutaneous or intramuscular administration, including Local Anesthetics and Radiographic Contrast Media. The increased systemic exposure (AUC/Cmax) of the co-administered drug is a formally noted outcome.

Substances whose effects may be affected by this interaction include Furosemide and Phenytoin. Furthermore, the enzyme's function itself can be inhibited by co-administered high doses of Salicylates, certain Corticosteroids, and Oestrogens.

Administration Restrictions and Incompatibilities

Official labeling specifies mandatory administration restrictions due to physical and chemical incompatibility with certain substances. Лидаза must not be mixed in the same syringe or solution with Furosemide, Phenytoin, or High-Dose Benzodiazepines. This is a requirement for separation of administration to avoid altering the integrity of the solutions. No specific interactions with food, alcohol, or herbal products are documented in regulatory sources.

Mechanism of Action

Enzymatic Degradation of Hyaluronan (Hyaluronic Acid)

Лидаза acts through the enzyme hyaluronidase, which constitutes its active substance. This mechanism engages the extracellular matrix (ECM) as its primary site of action. Hyaluronidase directly targets the glycosaminoglycan hyaluronic acid (HA), a large polymer that contributes significantly to the viscosity and structure of connective tissue. The enzyme initiates a mechanistic cascade by cleaving the beta-1,4-glycosidic bonds within the HA polymer chain. This interaction results in the depolymerization of HA into smaller, lower-molecular-weight fragments.


Extracellular Matrix Remodeling and Tissue Permeability

The depolymerization of HA by hyaluronidase reduces the viscosity and alters the physicochemical properties of the ECM. This modification influences the localized fluid dynamics and molecular movement within the tissues. The resulting system-level physiological consequence is a temporary and reversible increase in tissue permeability, which facilitates the diffusion and spread of co-administered molecules or fluids across the connective tissue barrier.

Dosage and Administration Information

How Лидаза Is Used: Official Administration Guidelines

The administration of Лидаза (Hyaluronidase) follows specific guidelines that dictate its use as an enzymatic adjuvant. The medicine is primarily administered via subcutaneous (SC) injection or infusion and must not be given intravenously (IV), as the enzyme is rapidly inactivated, rendering its spreading effects unachievable via that route.

The product is used as an event-driven, single-use injection, always administered immediately prior to or concurrent with the substance requiring enhanced dispersion; it is not used as a daily or scheduled medication.

Dosage and Administration

Procedure Standard Dosing (Adults) Administration Timing
Subcutaneous Fluid Administration (Hypodermoclysis) 150 USP units Injected prior to or into the subcutaneous fluid line
Increasing Dispersion of Injected Drugs 50 U to 300 U (typically 150 U) Added directly to the drug solution or administered first
Subcutaneous Urography 75 U over each scapula Administered followed by contrast medium injection

Procedural and Population Constraints

Administration protocols require careful adherence to procedural constraints. When used for hypodermoclysis, the total volume and flow rate of the co-administered fluid must be controlled and generally should not exceed limits used for standard intravenous infusion. Furthermore, there are special restrictions for use in premature infants and neonates undergoing hypodermoclysis, where the daily fluid volume must not be more than 25 mL/kg of body weight, and the administration rate must not exceed 2 mL per minute. The medicine is supplied as an injectable solution and must be visually inspected for particulate matter before use.

Recent Clinical Evidence

Research evidence / Overview of Studies for Лидаза


Evidence for Enhancing Subcutaneous Fluid Absorption

Research has explored the temporary role of the enzyme in the administration of fluids under the skin, a process sometimes studied in contexts related to hydration. Research examined this use primarily in short-term Randomized Controlled Trials (RCTs) and prospective studies. These trials were observed in populations including children needing hydration and adults in settings requiring supportive hydration. Researchers monitored outcomes related to the rate of fluid infusion, the total volume that can be delivered, and localized outcomes related to physical discomfort at the injection site.

The findings describe patterns observed in the studies where the enzyme was associated with measurements of increased fluid flow and larger administered volumes compared to subcutaneous administration alone. Studies report how symptoms evolved in the observed populations, specifically noting patterns where the enzyme-assisted delivery was observed in comparison to standard intravenous fluid delivery in certain patient groups. However, findings related to patient-reported outcomes describing perceived discomfort were mixed across different trials.

Studies on Dispersion of Co-administered Injected Drugs

The enzyme was evaluated in studies exploring its role in increasing the localized spread and absorption of other medications, such as local anesthetics. Studies explored how the enzyme affects the speed of absorption and the local area of distribution when co-administered. The data show patterns related to a wider distribution and faster onset of the co-administered drug effects in certain situations, such as nerve blocks for ophthalmic surgery. This research contributes to understanding symptom patterns related to the enzyme's role as a spreading factor.

Evidence Gaps and Areas of Research Uncertainty

The research landscape shows several limitations. For many indications, sample sizes were modest, and evidence quality varies across studies, particularly where controlled trials are difficult to execute (e.g., extravasation management). Comparative evidence is lacking for many potential drug combinations. The results apply only to the populations studied, and researchers acknowledge that the extent of the effect may vary widely depending on the patient and the specific context. This means that while studies help show what has been observed so far, research provides context but not individual predictions.
