Study shows positive results for novel, patient-controlled transdermal system (PCTS)...
A study published in Anesthesia & Analgesia found that patients who used E-TRANS Fentanyl HCI PCTS experienced better pain control and fewer withdrawals compared to those who received a placebo. The novel transdermal system, approximately the size of a credit card, allows patients to control their pain management without needles or pumps.
