Meloxicam and diclofenac do not change VEGF and PDGF-ABserum levels of platelet-rich plasma.

BACKGROUND/AIM Platelet-rich plasma (PRP) application has gained widespread interest for musculoskeletal injuries. Nonsteroidal antiinflammatory drugs are frequently used in sports medicine before and/or after PRP application. Our study seeks to determine whether serum levels of platelet-derived growth factor-AB (PDGF-AB) and vascular endothelial growth factor (VEGF) levels of PRP would be affected by nonsteroidal antiinflammatory drugs. MATERIALS AND METHODS Two different final concentrations of diclofenac (0.5 μg mL-1 and 2.5 μg mL-1), meloxicam (0.8 μg mL-1 and 2.0 μg mL-1), and acetylsalicylic acid (final concentration 450 μm) were obtained in separate tubes with PRPs prepared from 20 healthy male volunteers. Medicine-free PRP was the control group. Growth factors were measured using ELISA. RESULTS PDGF-AB and VEGF serum levels did not change with diclofenac, meloxicam, or acetylsalicylic acid addition. PDGF-AB and VEGF serum levels correlated with each other. CONCLUSION Diclofenac, meloxicam, and acetylsalicylic acid did not affect PDGF-AB and VEGF serum levels.
