Prescription, Nonprescription and Orphan Drugs01:02

Prescription, Nonprescription and Orphan Drugs

690
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: Synthetic and Semisynthetic Opioids01:15

Opioid Analgesics: Synthetic and Semisynthetic Opioids

223
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

183
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...

Analgesia and Pain Management01:25

Analgesia and Pain Management

504
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...

Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

437
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

159
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Area of Science:

  • Public Health
  • Epidemiology
  • Health Policy

Background:

  • Opioid prescription policies aim to curb misuse and opioid use disorder (OUD).
  • While OUD prevalence may be declining, OUD incidence trends require further investigation.
  • Understanding OUD incidence changes is crucial for public health strategies.

Purpose of the Study:

  • To analyze trends in opioid use disorder incidence rates.
  • To identify population-level changes in OUD incidence.
  • To examine OUD incidence within demographic subgroups over time.

Main Methods:

  • Longitudinal analysis of incident OUD diagnoses in Vermont (July 2017–December 2021).
  • Utilized Vermont's all-payer claims database for individuals aged 16+.
  • Employed Poisson regression models, controlling for covariates and testing for moderation by age, sex, rurality, and insurance type.

Main Results:

  • A 0.8% monthly decrease in OUD incidence rate observed overall.
  • Age significantly moderated OUD incidence trends.
  • The most substantial monthly decrease (1.6%) was seen in individuals aged 16-29 years.

Conclusions:

  • Vermont's policy limiting opioid prescriptions correlated with decreased OUD incidence.
  • The decline in OUD incidence persisted through the COVID-19 pandemic.
  • Adolescents and young adults experienced the most significant reduction in OUD incidence.
