EFFECTS OF MAO-B AND COMT INHIBITORS ON SLEEP DISTURBANCES IN PARKINSON'S DISEASE: A NETWORK META-ANALYSIS (ADPD 2026) - "Inclusion criteria involved (1) patients with PD, (2) intervention/comparator consisting of MAO-B inhibitors (safinamide, rasagiline, or selegiline) and COMT inhibitors (opicapone, entacapone, or tolcapone), and (3) outcomes of improvement in parameters for subjective and objective sleep in randomized controlled trials and cohort studies. A total of 529 articles were identified during the initial search, and we ultimately conducted an NMA focusing on the final seven studies. Evidence has shown that safinamide is effective in improving objective sleep parameters in patients with PD. However, given the paucity of evidence and controlled, long-term studies, the effects of MAO-B and COMT inhibitors on sleep disturbances remain unclear. More high-quality studies will be needed and should enable clinicians to provide personalized medicine based on sleep profiles."

EFFICACY OF MAO-B AND COMT INHIBITORS ON QUALITY OF LIFE IN PATIENTS WITH PARKINSON'S DISEASE: A BAYESIAN NETWORK META-ANALYSIS (ADPD 2026) - "Randomized controlled trials evaluating QoL using PDQ-39 or PDQ-8 in patients treated with MAO-B inhibitors (rasagiline, selegiline, safinamide) or COMT inhibitors (entacapone, opicapone, tolcapone) were included. This network meta-analysis provides evidence that MAO-B inhibitors, particularly rasagiline and safinamide, may offer broader QoL benefits in patients with PD, especially in NMS such as emotional well-being. These findings support a more symptom-oriented and individualized treatment approach should be provided to patients with PD. Further well-designed head-to-head studies using standardized QoL measures and extended follow-up are needed to confirm these findings and guide clinical practice."

Pharmacokinetics and pharmacodynamics of anti-Parkinson drugs in geriatric patients : Key for optimization of treatment (PubMed, Z Gerontol Geriatr) - "The decarboxylase inhibitors benserazide and carbidopa possess different t1/2...Absorption and elimination of entacapone and opicapone are similar to levodopa...Rasagiline and selegiline are irreversible inhibitors of monoamine oxidase B. Therefore, in spite of their short t1/2 they are dosed once daily...Clinically established dopamine agonists activate D1/D5 dopamine motor receptors less strongly than the dopaminergic receptors of D2/D3/D4group. This is a probable reason for their numerous adverse effects particularly in older people with Parkinson's disease."

Early start of opicapone in Parkinson's disease: evidence from a pooled analysis of phase 3 trials for sustained benefit in patients with recent onset of motor fluctuations. (PubMed, Front Neurol) - "Early initiation of opicapone in PD patients with recently diagnosed motor fluctuations leads to sustained reductions in OFF-time and improvements in ON-time, without increasing dyskinesia or requiring escalation of levodopa doses. These exploratory findings support revising treatment strategies to include earlier use of opicapone, maximizing long-term benefits for patients with fluctuating PD."

Faith, fasting, and well-being: Emirates Neurology Society consensus guidelines on safe Ramadan fasting in Parkinson's disease. (PubMed, Front Neurol) - "Long-acting dopaminergic therapies, including Dopamine Agonists (rotigotine patches and other extended-release (ER) oral agents), adjunctive agents (opicapone, rasagilline and safinamide), and Device-Aided Treatments (DAT; subcutaneous foslevodopa-foscarbidopa, subcutaneous continous subcutaneous apomorphine infusion, levodopa-carbidopa intestinal gel and deep brain stimulation) can help stabilize motor and non-motor fluctuations. Safe Ramadan fasting in PD requires comprehensive pre-Ramadan assessment, stage-specific therapeutic strategies, and proactive management of both motor and non-motor complications. Shared decision-making that integrates medical, psychological, and religious considerations is vital to optimize patient outcomes while respecting spiritual values."

Treatment strategies for motor fluctuations in Parkinson's disease: a systematic review of efficacy, functionality, and drug accessibility with a focus on Latin America. (PubMed, Front Pharmacol) - "High-certainty evidence supports the efficacy of extended-release levodopa (IPX066), opicapone, pramipexole, rotigotine, and safinamide in reducing OFF-time, although improvements in functional disability and quality of life were modest or inconsistent. Moderate-certainty evidence supports device-aided therapies, including levodopa-carbidopa intestinal gel (LCIG), subcutaneous foslevodopa-foscarbidopa, and continuous apomorphine infusion, which achieved larger effects on OFF-time and functional outcomes...In contrast, several newer therapies-such as IPX066, opicapone, istradefylline, and foslevodopa-foscarbidopa-were unavailable in most Latin American markets, and price differentials for controlled-release or add-on therapies were often several-fold higher after PPP adjustment...The Latin American region exemplifies these disparities, with limited regulatory availability, heterogeneous pricing, and insufficient inclusion of novel agents in national formularies...."

Nocturnal Hypokinesia and Early Morning OFF in Parkinson's Disease: State-of-the-Art and Systematic Review of Treatment Availability. (PubMed, Curr Neurol Neurosci Rep) - "Pharmacologic treatments include standard and sustained-release levodopa, dopamine agonists (rotigotine, ropinirol, pramipexole, and apomorphine), MAO-B inhibitors (rasagiline, safinamide), COMT inhibitors (opicapone), and rescue therapies like inhaled or dispersible levodopa or apomorphine injection. For mild, disturbing symptoms in early PD, inhaled or dispersible levodopa or apomorphine injection are advised. In moderate to advanced stages, treatment options include long-acting dopamine agonists, MAO-B inhibitors, sustained-release levodopa, or COMT inhibitors selected based on factors such as daytime motor symptoms, and non-motor symptoms."

Treatment Stability Across Different ADD-ON Therapies in Fluctuating Parkinson's Disease (MDS Congress 2025) - "Objective: This study investigates the efficacy and tolerability of selegiline (SL), rasagiline (RS), safinamide (SF), and opicapone (OP) in fluctuating PD patients, focusing on treatment stability and demographic influences. No single add-on therapy demonstrated superior stability, highlighting comparable efficacy across options. Sex significantly influenced therapy adjustments, with females requiring more frequent modifications. These findings underscore the importance of personalized treatment strategies in fluctuating PD management."
