Opioid Analgesics: Synthetic and Semisynthetic Opioids01:15

Opioid Analgesics: Synthetic and Semisynthetic Opioids

373
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...

Prescription, Nonprescription and Orphan Drugs

818
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...

Opioid Analgesics: Morphine and Other Natural Cogeners01:20

Opioid Analgesics: Morphine and Other Natural Cogeners

324
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...

Opioid Receptors: Overview01:22

Opioid Receptors: Overview

1.4K
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

Drug Distribution: Volume of Distribution01:25

Drug Distribution: Volume of Distribution

5.3K
The volume of distribution refers to the theoretical volume necessary to contain the entire amount of an administered drug at the same concentration observed in the blood plasma. The body's intracellular fluid compartment, which makes up two-thirds of the total body water, is contrasted with the extracellular fluid compartment—comprising plasma and interstitial fluid—that accounts for one-third. The volume of distribution can vary depending on the characteristics of the drug.

Analgesia and Pain Management01:25

Analgesia and Pain Management

711
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
  • Public Health
  • Epidemiology

Background:

  • Opioid dispensing is a critical public health concern.
  • Understanding dispensing patterns is essential for effective policy and service provision.

Purpose of the Study:

  • To analyze trends in opioid dispensing in Queensland between 2008 and 2018.
  • To examine dispensing patterns by recipient age, specific opioid drug, oral morphine equivalent (OME), and geographical remoteness.

Main Methods:

  • Utilized data from the Queensland Monitoring of Drugs of Dependence System (2008-2018).
  • Incorporated Australian Bureau of Statistics data for population adjustments.
  • Assessed opioid dispensing rates, OME, and geographical variations.

Main Results:

  • Total opioid prescriptions increased 2.3-fold per 1000 population.
  • Oxycodone dispensing rose 3.1-fold; tapentadol became the third most dispensed by 2018.
  • Dispensing rates were higher in inner and outer regional areas compared to major cities.
  • Opioid dispensing was triple in the 85+ age group compared to the 65-84 age group by 2018.
  • Overall OME increased approximately 1.9-fold.

Conclusions:

  • Significant shifts in opioid prescribing patterns, including drug choice and OME, were observed.
  • Geographical remoteness influences opioid dispensing rates, with higher rates in regional areas.
  • Further research linking databases is needed to understand dispensing drivers and inform policy.
