Opioid Analgesics: Synthetic and Semisynthetic Opioids01:15

Opioid Analgesics: Synthetic and Semisynthetic Opioids

824
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

Opioid Analgesics: Morphine and Other Natural Cogeners

760
Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...

Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

511
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

Prescription, Nonprescription and Orphan Drugs

1.1K
Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

Sedatives and Hypnotics Drugs: Miscellaneous Agents

428
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Analgesia and Pain Management01:25

Analgesia and Pain Management

1.4K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Area of Science:

  • Pharmacology
  • Pain Management
  • Addiction Medicine

Background:

  • Methadone is a widely used treatment for chronic pain and opioid use disorder.
  • Methadone use requires careful patient monitoring due to potential side effects like QTc prolongation and drug-drug interactions.
  • Levorphanol, a less commonly used opioid, presents a similar therapeutic profile to methadone.

Purpose of the Study:

  • To review and compare the safety considerations of methadone and levorphanol.
  • To highlight the potential advantages of levorphanol regarding cardiovascular safety and drug interactions.

Main Methods:

  • Literature review comparing safety profiles of methadone and levorphanol.
  • Analysis of existing clinical data and pharmacological properties.
  • Focus on adverse effects, drug interactions, and QTc prolongation.

Main Results:

  • Levorphanol does not appear to cause QTc prolongation.
  • Levorphanol exhibits fewer significant drug-drug interactions compared to methadone.
  • Practical challenges for levorphanol include limited availability and provider unfamiliarity.

Conclusions:

  • Levorphanol may offer a safer alternative to methadone for certain patients, particularly those at risk for QTc prolongation or experiencing drug interactions.
  • Further clinical research and wider availability are needed to facilitate levorphanol's use.
  • Both agents require careful clinical management, but levorphanol presents a distinct safety advantage.
