Apomorphine therapy in Parkinson's and future directions

Area of Science:

• Neurology
• Pharmacology
• Drug Delivery Systems

Background:

• Apomorphine is a dopamine agonist used for advanced Parkinson's disease (PD) with motor fluctuations.
• Current subcutaneous delivery faces challenges like skin irritation and patient avoidance.
• Apomorphine rapidly reverses "off" periods and shows efficacy for nonmotor symptoms.

Purpose of the Study:

• To review novel and future delivery strategies for apomorphine.
• To explore emerging research on apomorphine's potential neuroprotective effects.
• To discuss apomorphine's expanded role in managing nonmotor PD symptoms and related conditions.

Main Methods:

• Review of current literature on apomorphine delivery and research.
• Analysis of novel administration routes including oral, buccal, and inhalation.
• Examination of preclinical studies on apomorphine's effects in animal models.

Main Results:

• Several novel apomorphine delivery systems are under investigation, potentially overcoming subcutaneous injection issues.
• Apomorphine demonstrates potential anti-amyloid properties in animal models.
• Emerging evidence suggests apomorphine may benefit PD dementia and impulse control disorders.

Conclusions:

• Novel delivery methods promise improved patient compliance and broader therapeutic applications for apomorphine.
• Apomorphine's potential disease-modifying effects warrant further investigation in neurodegenerative diseases.
• Future research should focus on translating these findings into clinical practice for comprehensive Parkinson's disease management.
