Opioids, sometimes known as narcotics, are medications that doctors recommend to relieve severe or chronic pain. They are frequently used by people with chronic headaches and backaches, by patients recovering from surgery or dealing with severe pain related to cancer, by patients experiencing severe pain, by adults and children who have been seriously injured in falls, car accidents, or other incidents, as well as for managing chronic pain, cough and diarrhoea suppressants, anaesthetic agents, and opioid de-addiction therapy.

There is evidence that various cardiac functions are regulated by opioid receptors via various signaling pathways. Opioid receptors are primarily found in the central nervous system but are also found in peripheral tissues like the interstitial cells of Cajal, immune cells in the gastrointestinal tract, and the enteric plexus of the bowel. Myocardial infarction, ischemia reperfusion damage, atherosclerosis, etc. have all been successfully investigated for the positive effects of Long-Acting Opioids (LAO). On the other side, a number of research investigations have indicated that LAOs can have negative consequences that are primarily linked to QTc prolongation, torsade de pointes, ventricular arrhythmias, and cardiac arrest. The purpose of this review is to educate readers on the advantages and disadvantages of long-acting opioids for cardiovascular disorders [1].

Opioid receptors are proteins on nerve cells in the brain, spinal cord, gut, and other areas of the body that opioids bind to. When this occurs, the opioids stop the transmission of pain signals from the body to the brain via the spinal cord. Opioids can successfully reduce pain, but they also come with some hazards and have a significant potential for addiction. When opioids are used for a prolonged period of time to treat chronic pain, the risk of addiction is particularly high.

Nonetheless, it is generally recognised that opioids can have certain unpleasant side effects, such as immunosuppression, which is frequently disregarded. Because of this, individuals who use opioids long-term have an increased risk of opportunistic bacterial and viral infections. To treat opioid induced immune-suppression, there are currently no effective treatments. Effective therapeutic strategies can be developed by researchers if they are aware of the underlying molecular mechanism of opioids in immune-suppression [2].

Prescribed opioids come in a variety of forms and go by a number of names, including Fentanyl, Hydrocodone, Oxycodone, Oxymorphone, Morphine, and others.

Fentanyl is a potent synthetic opioid painkiller that is similar to morphine but 50–100 times stronger. Fentanyl is used to treat acute pain brought on by severe trauma during or following a procedure, a traumatic accident, or surgery, as well as persistent pain brought on by cancer. When lesser painkillers are no longer effective, it is also used to treat other types of chronic pain.

Hydrocodone is an artificial opioid made from the drug codeine. To treat moderate to severe pain, it is frequently used in conjunction with acetaminophen. Although dextromethorphan has mainly taken the position of hydrocodone in modern cough and cold remedies, hydrocodone has historically been used as a cough suppressor. In addition to finding widespread use as an analgesic, hydromorphone, hydrocodone's more potent metabolite, is commonly utilised in cases of extreme pain [3].

Oxycodone is used to relieve moderate to severe pain. Those who are likely to need pain medication 24 hours a day for a prolonged period of time and who are unable to be treated with other medications can get relief from severe pain from oxycodone extended-release tablets and extended-release capsules. In order to relieve pain that can be managed by medication taken as needed, oxycodone extended-release tablets and capsules should not be utilised. Only those who are tolerant of opioid drugs and have been taking them for at least one week should be treated with oxycodone extended-release tablets, extended-release capsules, and concentrated solution. Opiate (narcotic) analgesics, which include oxycodone, are a group of drugs used to treat pain.

Oxymorphone is an antagonist of opioids. It is a semi-synthetic narcotic analgesic related to hydromorphone and other opiates. Oxymorphone, or hydroxy-dihydromorphinone, affects the central nervous system and smooth muscles by activating particular opiate receptors. It is used to treat moderate to severe pain, including obstetrical pain, or as an adjuvant to anesthesia. It is similar to morphine but stronger and lacks cough suppressing effect [4].

Morphine pill is used to treat moderate to severe pain that is either short-term (acute) or long-term (chronic). When other painkillers did not work well enough or could not be tolerated, the extended-release capsule and extended-release tablet are used to treat pain that is severe enough to require daily, round-the-clock, long-term opioid medication. Morphine is a member of the class of drugs known as narcotic analgesics (pain medicines). To reduce pain, it works on the Central Nervous System (CNS) [5].
