However, since opioid antagonists also block the beneficial effects of opioid analgesics, they are generally useful only for treating overdose, with use of opioid antagonists alongside opioid analgesics to reduce side effects, requiring careful dose titration and often being poorly effective at doses low enough to allow analgesia to be maintained.
Opiates with opioid activity are mainly used for pain management with the premise that there will be benefits for both pain & function that will outweigh the risks to the patient. [25] Another indication is symptomatic relief of shortage of breath, both in the acute setting (for example, pulmonary edema) and in terminally ill patients. [26] [27]
As of 2015, an estimated 17 million people use opiates, of which heroin is the most common, [14] [15] and opioid use resulted in 122,000 deaths; [16] also, as of 2015, the total number of heroin users worldwide is believed to have increased in Africa, the Americas, and Asia since 2000. [17]
An analgesic drug, also called simply an analgesic, antalgic, pain reliever, or painkiller, is any member of the group of drugs used for pain management.Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and ...

Clinics that dispensed painkillers proliferated with only the loosest of safeguards, until a recent coordinated federal-state crackdown crushed many of the so-called “pill mills.” As the opioid pain meds became scarce, a cheaper opioid began to take over the market — heroin. Frieden said three quarters of heroin users started with pills.
Different drug classes have different side effects. Long-term medical conditions induced by opioid include infection, hyperalgesia, opioid-induced bowel syndrome, opioid-related leukoencephalopathy and opioid amnestic syndrome. [32] Misuse of prescribed opioids medications is associated with increased morbidity and mortality. [37]
Fentanyl is a highly potent synthetic piperidine opioid primarily used as an analgesic.It is 30 to 50 times more potent than heroin and 100 times more potent than morphine; [11] its primary clinical utility is in pain management for cancer patients and those recovering from painful surgeries.
