Levodopa/carbidopa/entacapone 200/50/200 mg (Stalevo ® 200) in the treatment of Parkinson's disease: a case series
Cases journal, 2009Co-Authors: Kapil D. Sethi, Robert A. Hauser, Stuart Isaacson, Terry McclainAbstract:Levodopa continues to be the most efficacious and widely used treatment for Parkinson's disease. Levodopa dosing is understood to be critical for the optimal control of symptoms, and increasing the levodopa dose is a common method to treat advancing disease. Escalating levodopa dosages coupled with disease progression is associated with increasing likelihood of developing levodopa-induced dyskinesia. Moreover, frequent and complicated dosing schemes, combined with limited dose availability, leads to increasing pill burden and its associated impairment of patient adherence issues. Levodopa/carbidopa/entacapone has been shown to improve the pharmacokinetic profile of levodopa and provide superior symptomatic control compared with conventional levodopa/dopa decarboxylase inhibitor therapy. We report four case histories describing clinical experience of using levodopa/carbidopa/entacapone 200/50/200 mg, one of the latest doses of this formulation, in a range of patients with Parkinson's disease. These cases illustrate that levodopa/carbidopa/entacapone 200/50/200 mg provides improvements in symptomatic control and convenience, and that switching to this dose was not associated with safety concerns.

Double-blind trial of levodopa/carbidopa/entacapone versus levodopa/carbidopa in early Parkinson's disease†‡
Movement disorders : official journal of the Movement Disorder Society, 2009Co-Authors: Robert A. Hauser, Michel Panisset, Giovanni Abbruzzese, Linda Mancione, Nalina Dronamraju, Algirdas KakariekaAbstract:We performed a 39-week, randomized, double-blind, multicenter study to compare the efficacy, safety, and tolerability of levodopa/carbidopa/entacapone (LCE, Stalevo) with levodopa/carbidopa (LC, Sinemet IR) in patients with early Parkinson's disease (PD). Four hundred twenty-three patients with early PD warranting levodopa were randomly assigned to treatment with LCE 100/25/200 or LC 100/25 three-times daily. The adjusted mean difference in total Unified Parkinson's disease Rating Scale (UPDRS) Parts II and III between groups using the analysis of covariance model (prespecified primary outcome measure) was 1.7 (standard error = 0.84) points favoring LCE (P = 0.045). Significantly greater improvement with LCE compared with LC was also observed in UPDRS Part II activities of daily living (ADL) scores (P = 0.025), Schwab and England ADL scores (blinded rater, P = 0.003; subject, P = 0.006) and subject-reported Clinical Global Impression (CGI) scores (P = 0.047). There was no significant difference in UPDRS Part III or investigator-rated CGI scores. Wearing-off was observed in 29 (13.9%) subjects in the LCE group and 43 (20.0%) in the LC group (P = 0.099). Dyskinesia was observed in 11 (5.3%) subjects in the LCE group and 16 (7.4%) in the LC group (P = 0.367). Nausea and diarrhea were reported more frequently in the LCE group. LCE provided greater symptomatic benefit than LC and did not increase motor complications.

levodopa carbidopa entacapone Stalevo
Neurology, 2004Co-Authors: Robert A. HauserAbstract:A levodopa/carbidopa/entacapone combination product (Stalevo) was recently approved to treat patients with idiopathic Parkinson’s disease (PD) who experience end-of-dose “wearing-off.” Stalevo is available in dose combinations of levodopa/carbidopa/entacapone 50/12.5/200 mg (Stalevo 50), 100/25/200 mg (Stalevo 100), and 150/37.5/200 mg (Stalevo 150). A series of pharmacokinetic studies demonstrated bioequivalence between Stalevo and corresponding dosages of levodopa/carbidopa plus entacapone. A clinical advantage of Stalevo is that patients can take one pill rather than two (or more) separate tablets. In addition, Stalevo 50 and 100 tablets are smaller than entacapone tablets. These advantages may be particularly beneficial for patients taking many pills, those who have difficulty following complex medication regimens, and those with swallowing difficulty. Most PD patients taking levodopa/carbidopa immediate-release (IR) plus entacapone can be directly switched to the corresponding dose Stalevo product. For fluctuating PD patients taking levodopa/carbidopa IR without entacapone, switching to the corresponding Stalevo tablet is analogous to adding entacapone. In switching patients who are receiving levodopa/carbidopa controlled-release (CR), it should be noted that the bioavailability of levodopa from levodopa/carbidopa CR is approximately 70–75% that of levodopa/carbidopa IR products, including Stalevo.

Cost-effectiveness of levodopa/carbidopa/entacapone (Stalevo) compared to standard care in UK Parkinson's disease patients with wearing-off.
Current medical research and opinion, 2005Co-Authors: Leslie J Findley, Andrew J. Lees, Marjo Apajasalo, Anna Pitkänen, Heidi TurunenAbstract:ABSTRACTBackground and methods: A Markov model was developed to evaluate the cost-effectiveness of levodopa/carbidopa/entacapone (LCE;Stalevo*), in the treatment of patients with Parkinson's disease (PD) and end-of-dose motor fluctuations (wearing-off). LCE, with or without other antiparkinsonian medications, was compared to UK standard care, comprising traditional levodopa/dopa-decarboxylase inhibitor (DDCI) with other antiparkinsonian medications (e.g. selegiline or dopamine agonists) added as needed. The costs and outcomes of both treatments were projected over a period of 10 years from the perspective (a) of society as a whole and (b) of the UK National Health Service (NHS). Sensitivity analyses, including second-order Monte Carlo simulations, were performed to assess the confidence level of the primary results.Results: Treatment with LCE produced an average gain of +1.04 quality-adjusted life-years (QALYs) per patient (2.57 vs. 1.53) in the base-case analysis (discount rate 3.5%). This gain was accom...

conversion from sustained release carbidopa levodopa to carbidopa levodopa entacapone Stalevo in parkinson disease patients
Clinical Neuropharmacology, 2006Co-Authors: Kelly E. Lyons, Rajesh PahwaAbstract:Objectives: This study was performed to determine if conversion from sustained release carbidopa/levodopa (SR-CL) with or without entacapone to carbidopa/levodopa/entacapone (CLE; Stalevo) improves motor functioning and quality of life in Parkinson disease (PD) patients and to assess patient tolerance and drug preference. Methods: PD patients reporting suboptimal symptom control with SR-CL were converted to CLE. The basic conversion was 1 SR-CL 25/100 to 1 25/100/200 CLE and 1 SR-CL 50/200 to 1 37.5/150/200 CLE with additional changes as necessary. Results: There were 62 patients with an average age of 68 years and an average disease duration of 11 years. CLE was preferred by 42 patients and SR-CL was preferred by 20 patients. In those that preferred CLE, Unified Parkinson Disease Rating Scale (UPDRS) mentation and motor subscores, Parkinson Disease Questionnaire-39 (PDQ-39) quality-of-life activities of daily living (ADL) and bodily discomfort subscores, and Epworth Sleepiness Scale (ESS) scores were significantly improved. There were no significant changes in any measures in the group that preferred SR-CL. Common adverse effects in the group that preferred CLE included nausea, vomiting, increased dyskinesia or off time, dizziness, and somnolence. The most common adverse events in the group preferring SR-CL were increased off time or dyskinesia, nausea, and vomiting. Conclusions: A majority of patients suboptimally controlled on SR-CL can be successfully converted to CLE with improvements in motor function, quality of life, and sleepiness. Older patients, with longer disease duration not previously exposed to entacapone, may better tolerate CLE after the addition of entacapone.
