Parkinson's Disease: Treatment

1.4K
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions01:24

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

423
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...

IV Infusion to Oral Dosing: Conversion Methods

212
The development of extended-release formulations has facilitated the transition from intravenous to oral medication, offering a more convenient and patient-friendly approach to drug administration. This transition, however, requires careful management to ensure that therapeutic drug levels are maintained, preserving efficacy and avoiding adverse effects. Understanding pharmacokinetic principles and dosage calculations is critical during this process.Pharmacokinetics of the...

Drug Delivery: Parenteral Route

2.8K
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists

2.0K
Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...

Area of Science:

  • Neurology
  • Gastroenterology
  • Pharmacology

Background:

  • Levodopa/carbidopa intestinal gel (LCIG) is used for advanced Parkinson's disease.
  • Reimbursement in Belgium required data on LCIG's efficacy, safety, and patient satisfaction in clinical practice.

Purpose of the Study:

  • To evaluate the real-world efficacy, safety, and patient satisfaction of levodopa/carbidopa intestinal gel (LCIG) infusion.
  • To gather data necessary for maintaining drug reimbursement in Belgium.

Main Methods:

  • A prospective study included 100 patients with advanced Parkinson's disease across 27 Belgian neurology centers.
  • Efficacy was measured using the Unified Parkinson's Disease Rating Scale (UPDRS) IV, and patient appraisal via visual analog scales.
  • Safety was monitored through adverse drug reactions (ADRs) and device-related complaints.

Main Results:

  • 67 out of 100 patients received permanent LCIG treatment via percutaneous endoscopic gastrostomy and jejunal tube (PEG/J).
  • Significant improvement in motor complications (UPDRS IV) was observed (mean change -6.3).
  • High patient and family satisfaction scores were reported for user-friendliness and impact on daily life, with few ADRs or malfunctions.

Conclusions:

  • Levodopa/carbidopa intestinal gel (LCIG) via PEG/J significantly improved Parkinsonism symptoms and impact in routine clinical practice.
  • The treatment demonstrated a favorable safety profile and high patient satisfaction.
  • The study provides essential data for maintaining LCIG reimbursement.
