However, as tapentadol has a dose ceiling, so it’s listed as a morphine-equivalent ahead in order of strength to morphine. Tapentadol (Nucynta, Palexia SR): Technically, tapentadol could be classified as stronger than morphine, as clinical trials (3) indicate the medication provides superior analgesic effects than equivalent doses of oxycodone, but with significantly lower gastrointestinal side effects. The semi-synthetic opioid is synthesized from thebaine, an alkaloid found in the opium poppy and is approximately 1.5 times stronger than morphine. Oxycodone has a greater analgesic effect than morphine (6). There is also a lower risk of the user developing dose tolerance with methadone (2) as compared to other types of opioids. It is considered more potent than morphine due to its effectiveness against neuropathic pain. It’s also prescribed to treat opioid dependence in methadone maintenance programs. Methadone is an opioid painkiller medication used to treat moderate to severe pain. Levorphanol is several times more potent than morphine and is strongly addicting. Levorphanol is produced using one of the two enantiomers of the compound racemorphan. Levorphanol is a synthetic opioid painkiller medication created from the compound racemorphan and used to treat moderate to severe pain. is facing and is leading to mass overdose deaths. Heroin addiction is a contributing factor to the drug epidemic that the U.S. It’s estimated that heroin is approximately 2 to 4 times more potent than morphine. While heroin was once used in medical settings, it was made a Schedule I Substance under the Controlled Substances Act in 1924 and is now an illicit drug used primarily for recreational purposes. Heroin is created by combining the morphine alkaloid with acetic anhydride to create a more potent opioid analgesic drug. The medication is more soluble in water than morphine, which allows the drug to be delivered in a smaller amount of water. Hydromorphone is synthesized from morphine and is commonly used in hospital settings to treat moderate to severe pain. The powerful opioid medication is highly addictive and requires an opioid addiction treatment program to overcome, leading the FDA to ask the manufacturer to remove it from the US market in 2017. Oxymorphone is a semi-synthetic opioid painkiller medication commonly used to treat severe to chronic pain and to maintain anesthesia. Depending on the method of administration, it’s estimated that fentanyl can be up to 100 times more potent than morphine and is classified as one of the strongest opioids. It’s occasionally used as a part of the anesthesia process to help prevent pain following surgery but it is also used to treat severe pain. The opioid painkiller medication has a rapid onset and short duration of action. This drug can lead to abuse and addiction. Let’s take a look at some of the drugs that are stronger than morphine.įentanyl is common among drug abusers and is one of the strongest opioids on the market and is the strongest pain medication in hospital settings. Opioid use disorders (OUD) are on the rise. With those determinations in mind, the list of common opioids from strongest to weakest is also broken down into three classifications: stronger than morphine, morphine-equivalent and weaker than morphine. Essentially, the list of opioids strongest to weakest is determined by factoring in that a smaller dose of certain painkiller medications may be required to achieve the same pain-relief response to treat severe pain as can be reached with morphine. The actual potency of some narcotic pain medications and prescription opioids, or pain relievers by strength, may also vary, depending on the route of administration. Some of the strongest types of pain medication in a hospital may have a similar potency to morphine, but they may also be formulated with a dose ceiling, while morphine does not, rendering them less potent overall. Yet the list doesn’t determine whether the medication also has a similar mechanism of action. A report released by the CDC (1) listed various narcotic pain medications by strength as they compared to morphine. A Guide to Addictive Opiates: List of Opioids Strongest to WeakestĬreating a list of opioids from strongest to weakest is not as straightforward as simply listing them by potency or by an analgesic effect.
