Opioid Analgesics: Synthetic and Semisynthetic Opioids01:15

Opioid Analgesics: Synthetic and Semisynthetic Opioids

333
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...

Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

154
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.

Sedatives and Hypnotics Drugs: Miscellaneous Agents01:17

Sedatives and Hypnotics Drugs: Miscellaneous Agents

200
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...

Depolarizing Blockers: Pharmocokinetics01:19

Depolarizing Blockers: Pharmocokinetics

353
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

87
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Drug Delivery: Enteral Route01:18

Drug Delivery: Enteral Route

503
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Summary

Patients with advanced Parkinson's disease and severe insomnia benefit most from night-time apomorphine infusion. Prolonged Off periods are key indicators for successful treatment continuation.

Area of Science:

  • Neurology
  • Sleep Medicine
  • Pharmacology

Background:

  • A randomized controlled trial (APOMORPHEE) previously showed that night-time only subcutaneous apomorphine infusion improves sleep disturbances and insomnia in advanced Parkinson's disease patients.
  • This treatment is particularly beneficial for individuals experiencing moderate to severe insomnia.

Purpose of the Study:

  • To identify optimal patient candidates for night-time only subcutaneous apomorphine infusion in routine clinical practice.
  • To understand patient characteristics associated with treatment continuation.

Main Methods:

  • A post-hoc analysis of the APOMORPHEE trial data was conducted.
  • Patient characteristics were compared between those who continued and discontinued night-time only subcutaneous apomorphine infusion post-study.

Main Results:

  • Approximately half of the patients (22/42) opted to continue the treatment.
  • Continuation was associated with longer Off durations (day or night), painful Off dystonia, and greater baseline insomnia severity.
  • Multivariate analysis identified Off duration as the sole independent predictor of treatment continuation.

Conclusions:

  • Patients with severe and prolonged Off periods (both day and night) and severe insomnia are the most suitable candidates for night-time only apomorphine therapy.
  • Identifying these patient profiles can optimize treatment selection and improve outcomes in Parkinson's disease management.
