PRP, NSAIDs and take-home instructions introduction Platelet-rich plasma (PRP) is currently used to treat many different conditions, ranging from sports injuries to androgenic alopecia. It has been very popular in the sports medicine arena the past one to two decades. Many providers are aware of the instructions after a PRP treatment but may have not looked further into the reasoning behind them.
PRP is a biologic therapy is thought to promote healing by delivering the concentrated growth factors to damaged tissues and augment the natural healing process with mitogenesis or cellular proliferation through mitosis, chemotaxis, and other cellular processes. To release these restorative molecules, platelets must be activated. This complex process begins with binding of myriad agonists to platelet G-protein-coupled receptors (GPCRs) or immunoreceptor tyrosine-based activation motif complexes.
These lead to signaling cascades and platelet responses, including regulating surface receptors, and releasing growth factors into the environment through degranulation. Nonsteroidal anti-inflammatory drugs (NSAIDs) are thought to inhibit growth factor release by competitively and irreversibly inhibiting cyclooxygenase (COX) 1 and 2. More specifically, this is thought to occur through the inability of arachidonic acid (AA) to allow downstream thromboxane-A2 (TxA 2 ) binding to TxA 2 receptor to allow for platelet activation.
Consequently, many physicians recommend cessation of antiplatelet and anti-inflammatory drugs before initiating PRP therapy. While the results were not definitive, it appeared that the use of CaCl 2 or TBN alone as activation agents for PRP was, in general, not significantly affected by antiplatelets, and the use of collagen, ADP, and AA as activation agents showed a reduction in growth factors. There are limited high-quality data on the subject currently, and future clinical research is warranted.
Another recent review evaluated platelet function and aggregation for some common medications. In 73 patients, statin therapy did not result in a significant decrease in maximal platelet aggregation. Although there was not a significant difference in platelet aggregation with statin treatment when compared with control patients, treatment with statins did trend toward a significant decrease in aggregation.
If you are experiencing symptoms that may be related to prp, nsaids and take home instructions, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
