Overview of Placentex

What is Placentex? Defining the Core Pharmaceutical Entity

Placentex is a pharmaceutical preparation whose primary active constituent is Polydeoxyribonucleotide (PDRN). This drug is fundamentally classified as a tissue repair stimulator and regeneration promoter, an established high-level pharmacological category of a biostimulant. The formulation is specifically utilized for its ability to encourage fundamental biological healing and structural restoration processes within various tissues.

Property Description
Active ingredient Polydeoxyribonucleotide (PDRN)
Form Injectable aqueous solution, topical cream
Pharmacological class Tissue Repair Stimulator / Biostimulant
Common use General support for tissue restoration
Origin Biological (deoxyribonucleic extract)

Composition, Origin, and Available Form

The active substance, Polydeoxyribonucleotide, is a high-purity deoxyribonucleic extract of biological origin. PDRN is reliably obtained from a highly controlled purification and sterilization process of DNA derived from the sperm of specific salmon species, such as Oncorhynchus mykiss or Oncorhynchus keta. This rigorous extraction method is clinically recognized for yielding a final biopolymer that is non-immunogenic, which is a key differentiator when compared to less purified biological extracts.

Placentex is primarily dispensed as a sterile injectable aqueous solution, a formulation designed for highly targeted local delivery via various injection routes. This solution contains the PDRN active ingredient suspended in an aqueous base, optimizing its availability for tissue interaction. The substance is also manufactured as a sterile topical cream base, providing an alternative form for external, non-invasive application where localized tissue support is required.

General Purpose: Enhancing Tissue Regeneration

The general purpose of Placentex is to enhance and accelerate natural tissue regeneration and healing processes. It operates by facilitating improved tissue trophism and providing the necessary biological stimulus for cellular repair.

The unique regenerative effect of the Polydeoxyribonucleotide stems from its ability to selectively engage the adenosine A2A receptor and contribute raw materials for cellular synthesis. This mechanism establishes PDRN's role in promoting both vascularization and growth factors in the treated area, offering a foundational restorative approach rather than merely addressing superficial symptoms.

What side effects are possible with Placentex?

Possible Side Effects and Safety Information

The safety profile of Placentex (Polydeoxyribonucleotide or PDRN) primarily details localized reactions and the potential for hypersensitivity, as documented in government regulatory prescribing information. The adverse reactions are classified by frequency and grouped into specific physiological systems.


Officially Documented Adverse Reactions

The majority of documented effects are categorized as Common and are related to the site of administration, falling under the General Disorders and Administration Site Conditions system-organ class. These reactions are typically transient and resolve without intervention.

Classification System-Organ Class Examples of Effects
Common General Disorders and Administration Site Conditions Pain, redness (erythema), swelling (edema), stinging, and burning sensation at the injection site.
Not Known Immune System Disorders Systemic hypersensitivity reactions.

Serious Adverse Reactions and Safety Restrictions

Official regulatory sources note the potential for serious adverse reactions, particularly those related to the immune system. These include severe hypersensitivity reactions such as anaphylaxis and angioedema (swelling of the face, lips, or throat).

Due to this potential, the medicine is contraindicated in individuals with a known hypersensitivity to Polydeoxyribonucleotide or any of the product's excipients.

Overdose and Emergency Response

Overdose and When to Seek Help

This information is based strictly on the officially documented overdose profile for Placentex (Polydeoxyribonucleotide) as established in government regulatory sources, such as the Summary of Product Characteristics (SmPC) and other authorized labeling.


Documented Overdose Profile

The regulatory safety summaries for Placentex indicate that the risk of acute toxicity resulting from excessive use is considered very low. Official prescribing information, where available, typically does not detail a specific overdose syndrome for the active ingredient, Polydeoxyribonucleotide (PDRN).

  • Specific Symptoms: No specific clinical manifestations, such as unique signs or toxic symptoms, have been officially described or mandated for monitoring following an overdose event.
  • Systemic Effects: No particular physiological system is officially identified as being at risk of failure or severe compromise due to an acute overdose.
  • Antidote/Management: Regulatory documents do not specify a known antidote. Management, if required, would focus on supportive care addressing general systemic symptoms rather than counteracting specific drug toxicity.

When to Seek Immediate Medical Help

Given the absence of a defined toxic overdose profile, the instruction to seek immediate medical help is generally based on the occurrence of any severe, unexpected systemic reaction or profound discomfort following excessive administration. You must contact emergency services or a poison control center immediately if any symptoms arise that suggest a serious medical emergency, such as difficulty breathing, sudden collapse, or prolonged changes in consciousness or heart rate.

Therapeutic Uses of Placentex

Placentex is commonly used to offer supportive therapeutic benefit by acting as a biostimulant, supporting the body's natural processes of tissue repair. PDRN is relevant in conditions involving structural damage, including the clinical management of superficial wounds and skin ulcers. It is used across domains where localized tissue damage or degeneration is the primary issue, assisting in the management of distressing structural and functional manifestations.


The medication is commonly used to help manage conditions characterized by impaired tissue integrity, including chronic non-healing wounds and certain diabetic foot ulcers. It is also applied across conditions involving dermal structural degradation, and may assist with symptoms related to aging, such as loss of elasticity, fine lines, and acne scars, and supports tissues during post-procedural recovery. Furthermore, it assists with conditions that present with functional impairment due to soft tissue degeneration, including tendinopathies.

“The use is relevant in situations where symptoms relate to chronic tissue damage and require supportive relief.”

The use is relevant in situations where symptoms create noticeable functional strain or when additional symptomatic support is needed. The benefit provided helps manage conditions where structural repair is needed, which assists with maintaining functional stability and supports general well-being during symptomatic phases.


Quick Fact: Support for Chronic Tissue Conditions

Placentex is relevant for managing Wood conditions marked by persistent symptoms related to structural damage, contributing to regenerative processes and helping ease the overall symptom load.

Eligibility and Restrictions for Use

Placentex, which contains human placental extract, is prescribed for conditions related to tissue repair and regeneration.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Official regulatory documentation on Placentex (Polydeoxyribonucleotide) defines its interaction profile primarily through pharmacodynamic restrictions and specific pharmacokinetic properties. Information on drug interactions must be consistent with statements issued by government health authorities.

Documented Interaction Patterns

Interaction Type Interacting Substance/Class Official Constraint or Outcome
Pharmacodynamic Restriction Corticosteroids (Systemic or Local) and Systemic Immunosuppressive Agents Formal restriction against co-administration due to potential interference with the drug’s regenerative and biostimulant activity.
Timing Requirements Corticosteroids/Immunosuppressives Administration requires an exclusion or wash-out period (e.g., one month) for these agents prior to use, as noted in regulatory-aligned protocols.
Metabolic Non-Interaction CYP450 Enzyme System Documented absence of interaction risk; the drug is not metabolized by the hepatic CYP450 system but is cleared by non-specific plasma DNA nucleases.
Food/Substance Interaction Food, Alcohol, Herbal Products No interactions with food, alcohol, or herbal products are explicitly documented in official regulatory summaries.

Official Regulatory Summary

The established regulatory structure emphasizes that the drug is free from known hepatic metabolic interactions due to its clearance pathway, which bypasses the CYP450 enzyme system. The most significant interaction constraint is the necessary exclusion of strong anti-inflammatory and immunosuppressive therapies. This restriction is a mandatory measure to prevent the pharmacodynamic counteraction of Placentex’s intended tissue support effects.

Mechanism of Action

How Placentex Works

The mechanism of Placentex (PDRN) is defined by a dual-action strategy that modulates cellular signaling while providing fundamental biological materials for repair. This strategy focuses on engaging specific molecular targets to modulate pathways associated with tissue restoration.


1. Activation of Receptor Signaling and Anti-inflammation

This domain centers on the Adenosine A 2A Receptor ( A 2A AR), which is activated by PDRN's breakdown product, adenosine. Agonism of this receptor modulates key inflammatory pathways (like NF-kappa B), leading to the suppression of excessive pro-inflammatory signals, thereby contributing to the dampening of inflammatory cascade effects.

2. Stimulation of Angiogenesis and Tissue Trophism

A 2A AR activation further triggers the release of Vascular Endothelial Growth Factor (VEGF). This mechanistic cascade drives neovascularization (new blood vessel formation), which increases localized blood flow and nutrient delivery (trophism).

3. Provision of Building Blocks for Cellular Synthesis

This non-receptor mechanism utilizes the Salvage Pathway, where PDRN fragments are directly incorporated by cells (like fibroblasts) into new DNA and RNA strands. This provides the essential nucleotide precursors required for cell proliferation and the synthesis of new structural proteins, facilitating the synthesis and deposition of new extracellular matrix components.

Dosage and Administration Information

Administration Scope

Placentex (Polydeoxyribonucleotide) administration is characterized by a specific route, dose, and schedule for each available formulation. The drug is available as an injectable solution in two primary strengths: 5.625 mg/3 ml and 2.25 mg/3 ml ampoules, along with topical forms such as a 0.08% cream. The injectable solution is designated for intramuscular (i.m.) or subcutaneous (s.c.) routes, requiring administration under professional supervision. Topical forms, including the cutaneous solution and cream, are intended for local external application, and the ophthalmic solution is administered via instillation into the conjunctival fornix.

The established dosing regimen for the injectable solution is 1 ampoule per day, irrespective of the chosen strength, for parenteral use. Topical forms are typically applied 1 or 2 times per day, while the eye drops require 2 to 4 instillations per day. The overall course for the injectable form is structured in short, repeatable treatment cycles of 15 - 20 days. The injectable solution is ready-to-use and does not require dilution. No specific dose adjustments are indicated for patient groups such as older adults or those with renal impairment. All use is subject to the prescriber's determination.

Recent Clinical Evidence

Research evidence / Overview of studies for Placentex

Evidence for use in Chronic Non-Healing Wounds and Ulcers

Research involving Polydeoxyribonucleotide (PDRN) for conditions marked by functional limitations like chronic non-healing wounds and skin ulcers included Randomized Controlled Trials (RCTs) and systematic reviews. These studies included adult and older adult populations, frequently involving individuals diagnosed with diabetic foot ulcers. Researchers monitored specific outcomes related to wound closure, such as the time elapsed until reaching primary wound closure endpoints and measured changes in the surface area of the ulcer over defined observation periods.

Evidence for use in Soft Tissue and Joint Conditions

PDRN was studied for its application in conditions where symptoms may vary in intensity, such as chronic tendinopathy and certain joint pains. The research examined these outcomes related to physical discomfort using a combination of RCTs and observational studies. The primary measurements relied on patient-reported outcomes describing perceived discomfort, such as pain scores, and objective assessments of outcomes reflecting daily functioning or activity level.

Evidence for use in Dermal Structure Support

The research exploring PDRN’s role in supporting dermal structure, such as for skin elasticity and certain aesthetic conditions, is primarily based on smaller observational settings evaluating daily-life functioning (case series) and extensive preclinical investigations. These studies included adult populations, with outcomes monitored including skin hydration, elasticity measurements, and assessments of features like wrinkle depth.

Follow-up and Long-Term Research

Research on PDRN typically monitors patient response over defined time intervals, with most major clinical trials focusing on short- to intermediate-term outcomes. For chronic wounds, the primary endpoints are often assessed within 8 to 12 weeks. However, the long-term effects are not fully established concerning the maintenance of functional status or the continued absence of symptoms over years, especially after the study period has concluded.

Areas Where Research Remains Limited

Scientific reviews indicate several areas where the PDRN evidence base requires further development. The evidence quality varies across studies, with findings often being mixed across different research groups, contributing to research uncertainty. The establishment of standardized administration protocols—including the optimal dosage and delivery method—is not fully established and remains a research gap.
