Abstract

OBJECTIVES

We aimed to assess ease of use, convenience, self-efficacy, and satisfaction with long-term use of foslevodopa/foscarbidopa (LDp/CDp), a 24-h continuous subcutaneous infusion therapy delivered via an external portable pump for managing motor fluctuations in people with Parkinson's disease (PwP).

METHODS

PwP using LDp/CDp for ≥ 6 months and enrolled in an open-label study participated in semi-structured interviews, which were qualitatively analyzed using a content and thematic approach.

RESULTS

Nineteen adults, with an average (standard deviation) age of 63.6 (10.8) years, disease duration of 9.2 (3.4) years, and duration of LDp/CDp use of 15.4 (3.4) months, were interviewed. Most found LDp/CDp to be user-friendly (89.5%) and reliable (100%), and developed strategies to integrate the pump into their daily lives. The pump was commonly worn crossbody or around the waist, with minimal impact on sleep, though participants emphasized being mindful of the infusion set tubing to prevent tangling. Participants established routines using reminders, alarms, or schedules, and 84.2% prepared the pump in ≤ 20 min. Most (81.3%) were confident using LDp/CDp independently and 92.3% were satisfied with LDp/CDp, citing improved, consistent symptom control that allowed more freedom to participate in daily and social activities. Participants suggested improvements for the pump, including making it smaller and lighter.

CONCLUSION

PwP expressed high satisfaction and willingness to continue using LDp/CDp. PwP and their care partners developed innovative strategies to integrate the pump into daily routines, and the perceived symptom improvement drove successful persistence on this well-tolerated treatment.

Parkinson's Disease: Treatment 01:24

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...

Parkinson's Disease: Overview 01:15

499

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Drugs, the chemical agents used in diagnosing, treating, or preventing diseases, undergo a four-phase process of development: pharmaceutic, pharmacokinetics, pharmacodynamics, and therapeutic.
The pharmaceutical phase focuses on leveraging the physicochemical properties of the drug to design and manufacture an effective product. Variants include orally administered tablets or capsules, topical creams or ointments, and parenteral-delivery solutions or emulsions.
The pharmacokinetic phase...

Nonlinear Pharmacokinetics: Dependence of Elimination Half-Life and Dose Clearance 01:23

The elimination half-life and drug clearance of drugs following nonlinear kinetics can vary with dosage. The Michaelis-Menten parameters and drug concentration influence these factors. As the dose increases, the elimination half-life tends to lengthen, resulting in a reduction in clearance and a disproportionately larger area under the curve. The total clearance can be derived from the Michaelis-Menten equation for drugs following a one-compartment model.

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.
