Psychiatric Comorbidities in Parkinson's Disease: A Moroccan Perspective on Anxiety and Depression. (PubMed, Diseases) - "L-DOPA alone was used to treat half of the patients, while combinations of Trivastal, Sifrol, anticholinergics, or antidepressants were given to the other half. Regardless of the method of treatment or stage of the disease, psychiatric symptoms are prevalent. For PD patients to benefit from early interventions and achieve an improved quality of life, routine screening is crucial."

Remarkable therapeutic effects of methylphenidate in periodic limb movement disorder comorbid with excessive daytime sleepiness: a case report. (PubMed, Front Neurosci) - "Initially, we used levodopa 250 mg per night for 12 weeks, then piribedil 50 mg per night was arranged as the second drug for 12 weeks, and the third drug, pramipexole, was prescribed at a dosage of 0.25 mg per night for 12 weeks, but the EDS was persistent despite the periodic leg movement index (PLMI) returning to normal. A 2.5-year follow-up was scheduled for taking methylphenidate; the symptoms of EDS were steadily well controlled, and PLMI was still kept in the normal range. This finding suggests that methylphenidate is an optimal therapeutic approach for the management of PLMD comorbid EDS."

Multigenetic pharmacogenomics-guided treatment shows greater improvements on motor symptoms compared to usual therapy in Parkinson's disease: a small real-word prospective cohort study. (PubMed, Front Pharmacol) - "These differences remained significant after adjusting for increases in levodopa equivalent daily dose (p = 0.011 and p = 0.002, respectively) and piribedil use (p = 0.006 and p = 0.004, respectively)...Additionally, we identified several SNPs associated with the responsiveness to chronic administration of multiple anti-parkinsonian drugs. However, to confirm these findings, well-designed studies with larger, well-characterized samples are necessary."

A novel arylpiperazine derivative (LQFM181) protects against neurotoxicity induced by 3- nitropropionic acid in in vitro and in vivo models. (PubMed, Chem Biol Interact) - "In the pursuit of novel antioxidant therapies for the prevention and treatment of neurodegenerative diseases, three new arylpiperazine derivatives (LQFM181, LQFM276, and LQFM277) were synthesized through a molecular hybridization approach involving piribedil and butylated hydroxytoluene lead compounds...Interestingly, using the same in vivo model, LQFM181 also reduced locomotor behavior and memory dysfunction through its ability to decrease cholinesterase activity. Consequently, LQFM181 emerges as a promising candidate for further investigation into its neuroprotective potential, positioning it as a new therapeutic agent for neuroprotection."

Prescription patterns in treatment of Parkinson's disease in tertiary centers in Poland (CONy 2024) - "465 patients were treated with LD (mean dose 810.58mg), 292 with DA (ropinirole – 176 (mean dose 8.64mg), pramipexole – 105 (mean dose 1.76mg), piribedil - 8, rotigotine - 3), 202 with MAO-B inhibitors (rasagiline 198, selegiline 4), 197 with amantadine, 7 with entacapone and 4 with anticholinergics. Patients were divided into subgroups depending on their HY score, age and duration of the disease, then pharmacotherapy of each group was analyzed showing that in every group levodopa was most often prescribed drug and remains a gold standard in treatment of PD in tertiary centers in Poland. Dopamine agonists were the second most frequently prescribed group of medications in our study, although they were less frequently used in older population (70 years old) and with HY score of 3 or more."

Stereoselective synthesis of C-substituted piperazines mediated by an iridium catalyst (ACS-Fall 2023) - "Piperazine is considered a privileged scaffold in medicinal chemistry,[1] which has been used in a vast number of drugs across different areas, such as indinavir for HIV treatment, imatinib for chemotherapy, and piribedil for antiparkinsonian treatment. However, their synthesis is often accompanied by stereoselectivity problems and, in some cases, challenging multi-step synthetic processes. Therefore, selective, atom-economical methods for forming C-substituted piperazines from easily synthesized precursors, which can be modified to obtain a range of different piperazines, are highly desirable.[2] Recent research has shown significant progress in this area, such as the synthesis of C-substituted piperazines starting from imines containing aromatic substituents using an aluminum complex, as reported by Mendoza et al.[3]Herein, we report a stereoselective catalytic method for synthesizing C-substituted piperazines from imines with both aromatic and aliphatic substituents,..."

Comparative efficacy and safety of six non-ergot dopamine-receptor agonists in early Parkinson's disease: a systematic review and network meta-analysis. (PubMed, Front Neurol) - "Novel long-acting formulations of NEDAs including pramipexole extended-release (ER), ropinirole prolonged-release (PR), and rotigotine transdermal patch have been developed. In addition, the incidence of adverse reaction of ropinirole IR was relatively high (nausea: 0.678; somnolence: 0.752; dizziness: 0.758; fatigue: 0.890). In this systematic review and network meta-analysis of six NEDAs, piribedil exhibited better efficacy, especially as monotherapy, and ropinirole IR was associated with a higher incidence of adverse events in patients with early PD."

[VIRTUAL] Deterioration in oral health status potentially associated with apomorphine pump initiation: a case report (MDS Congress 2021) - "However, little is known about the effects of continuous subcutaneous apomorphine infusion (CSAI) on oral status...Concomitant treatment included rasagiline, levodopa/benserazide, piribedil, alfuzosine, domperidone and metformine... This case warrants further investigation on the effect of CSAI on the oral cavity. It also illustrates the necessity of multidisciplinary follow-up in PD patients, as underreporting is a major limitation to drug safety surveillance."
