Abstract:The escalating incidence of cancer has led to a heightened focus on chronic cancer pain within the domain of pain management. Opioid medications, serving as the principal treatment for moderate to severe chronic cancer pain, encompass potent opioids such as transdermal fentanyl (TDF), morphine sulfate extended-release tablets, and oxycodone hydrochloride extended-release tablets.
