Polydioxanone
Polydioxanone is a colorless, crystalline semi-crystalline thermoplastic poly (ether-ester) bioabsorbable polymer. Polydioxanone serves as a hemostatic agent, biodegradable agent, degradant, lumen patency maintainer, as well as a temporary inducer of tracheal tissue injury and inflammation. Polydioxanone controls bone bleeding in biocompatible matrices, degrades via random hydrolytic scission and end-chain scission, with accelerated degradation occurring at pH <1.67, maintains tracheal lumen patency, and induces reversible tracheal epithelial necrosis, inflammation, fibrous tissue hyperplasia, and goblet cell hyperplasia. Polydioxanone can be used in research on bone bleeding, non-malignant tracheal stenosis, tracheobronchial stenosis, tracheobronchomalacia, and airway obstruction associated with vascular compression.

Biological Activity
Polydioxanone (50% hydroxyapatite loading in PDX scaffold) electrospun scaffolds exhibit superior mineralization potential compared to PLGA/50% HA scaffolds in ionic and revised simulated body fluids[2].
Polydioxanone (50:50 PDX/elastin scaffold; 7 days) electrospun scaffolds support full thickness migration of human dermal fibroblasts within 7 days, unlike pure PDX scaffolds[2].
Polydioxanone (0-40% PDX loading in composite scaffolds; 7-21 days)/fibrinogen composite scaffolds support human bladder smooth muscle cell migration, spreading, and layered growth, with higher PDX content promoting cell morphologies closer to native bladder smooth muscle cells over 21 days[2].
Polydioxanone (varying degrees of grafted PDX chains; to 100% release endpoint) copolymers provide sustained release of Ibuprofen (HY-78131) in pH 7.4 PBS, with slower release rates associated with higher degrees of grafted PDX chains compared to pure chitosan carriers[2].
Polydioxanone (42-167 mg/mL) solutions in HFP exhibit viscosity ranging from 50 to 2856 cP across concentrations of 42 to 167 mg/mL, with a defined optimal viscosity range for electrospinning[3].
Dry polydioxanone (42-167 mg/mL) electrospun scaffolds exhibit anisotropic mechanical properties, with higher strength and rigidity in the longitudinal orientation of aligned fibers, and increasing mechanical performance with increasing PDS concentration; hydration of 100 mg/mL scaffolds increases strain at failure without adversely affecting modulus or peak stress[3].
Polydioxanone (10% Vancomycin (HY-B0671) + 10% Rifampicin (HY-B0272) loading in PDX fibers) electrospun fibers exhibit superior inhibition of osteomyelitis-associated bacterial biofilm growth compared to single-drug loaded and pure PDX fibers[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Polydioxanone (single administration) tracheal stents induce peak tracheal mucosal inflammation in rabbits 5 weeks post-implantation, with rapid stent degradation initiating at ~90 days and inflammation reducing thereafter[6].
The polydioxanone stent (6 mm diameter, 30 mm length braided; bronchoscopically and fluoroscopically guided implantation; single dose) demonstrates acceptable safety and biocompatibility in the rabbit tracheal model, fully degrading by 10 weeks post-implantation and leaving only minimal scar tissue and mild inflammation by 15 weeks, despite causing a peak mean tracheal damage score of 3.53 at 5 weeks[7].

Animal Model:unspecified strain[1]
-
Dosage:1 cm × 1 cm solid pellets; two small spatula scoopfuls granule/powder; 0.25 mL liquid
-
Administration:implanted (solid pellets, granule/powder); injected (liquid); single dose; 7 days observation
-
Result:Exhibited no adverse tissue reaction and kept bone wax intact after 7 days (formulation with 71 wt% polydioxanone + 29 wt% Deltyl Prime).
Exhibited no adverse tissue reaction, kept bone wax intact, showed a very thin capsule in one rat and slight hemorrhage in another after 7 days (formulation with 68.2 wt% polydioxanone + 31.8 wt% Sesame Oil).
Caused bone wax to be thickly encapsulated with bloody fluid, presented white spongy mass (encapsulated bone wax with fluid), and discolored bone wax disc after 7 days (formulation with 74.7 wt% polydioxanone + 25.3 wt% Carbowax 400).
Caused bone wax to be moderately encapsulated with clear fluid, showed white granular material dispersed in capsule after 7 days (formulation with 68.2 wt% polydioxanone + 31.8 wt% Pluronic P84).
Exhibited no adverse tissue reaction and had granules thinly encapsulated after 7 days (washed low molecular weight polydioxanone alone).

Animal Model:White New Zealand (10-month-old female, average weight 3.2 kg, tracheal stent implantation model)[7]
-
Dosage:6 mm diameter, 30 mm length braided polydioxanone stent
-
Administration:bronchoscopically and fluoroscopically guided implantation; single dose
-
Result:Caused no unexpected deaths, stent displacements, or stent debris expectoration during the study.
Induced mild respiratory distress in the first 2 weeks post-implantation, with progressive reduction from week 5 onward, and only mild stridor in weeks 14-15.
Maintained an open tracheal lumen throughout the study via macroscopic examination.
Resulted in a peak mean tracheal damage score (TDS) of 3.53 at 5 weeks post-implantation.
Achieved complete degradation with no remnants detected by 10 weeks post-implantation.
Left slightly hyperemic mucosa without hyperplasia, minimal scar tissue at implantation site, and mild lymphoplasmacytic infiltration by 15 weeks post-implantation.
Produced significantly higher TDS than the nonstented control group in all experimental groups (Mann-Whitney U test, all P < .009).
