Clinical experience with the novel levodopa formulation entacapone + levodopa + carbidopa (Stalevo).
Levodopa is the main pharmacologic treatment for Parkinson's disease. However, the long-term administration of levodopa is associated with the development of motor complications which can seriously compromise patient function. Increasing evidence indicates that such problems are related to abnormal pulsatile stimulation of striatal dopamine receptors and that treatments providing more continuous stimulation reduce the risk of motor complications. It is possible that administering levodopa with a reversible catechol-O-methyl transferase inhibitor at frequent intervals might reduce the risk of these complications. Stalevo (Orion) combines levodopa, the dopa-decarboxylase inhibitor carbidopa and the catechol-O-methyl transferase inhibitor entacapone in a single tablet. This review provides an overview of the initial clinical experience gained with Stalevo during clinical trials, including several case studies.

Patient satisfaction with switching to Stalevo: an open-label evaluation in PD patients experiencing wearing-off (Simcom Study).
This study investigated the ease with which 52 Parkinson's disease patients already receiving adjunct entacapone to traditional levodopa were switched to Stalevo (levodopa/carbidopa/entacapone).. The switch to Stalevo was straightforward for most patients taking standard-release levodopa with 86% of these patients being able to replace their entire regimen without having to change the amount of levodopa taken. The majority of patients (54%, P = 0.162) preferred Stalevo; 31% preferred their prior treatment regimen; 15% had no preference. Patients found Stalevo more simple to dose (94%), more convenient to use (84%), easier to handle (84%), easier to remember (67%) and easier to swallow (59%), compared with their previous medication.. Stalevo was well tolerated, with a low incidence of adverse events. The study shows that Stalevo is an effective, preferred and well-tolerated means of delivering levodopa/carbidopa/entacapone in one easy-to-use tablet.

Treatment of end-of-dose wearing-off in parkinson's disease: stalevo (levodopa/carbidopa/entacapone) and levodopa/DDCI given in combination with Comtess/Comtan (entacapone) provide equivalent improvements in symptom control superior to that of traditional
The aim of this study was to evaluate the efficacy of the new optimised levodopa, Stalevo (levodopa, carbidopa and entacapone) in patients with Parkinson's disease experiencing end-of-dose wearing-off. Treatment with Stalevo was compared to treatment with traditional immediate-release levodopa and dopa-decarboxylase inhibitor (DDCI) formulations along with adjunct entacapone (Comtess/Comtan). A European, open, parallel-group, active treatment-controlled phase IIIb study evaluating 176 patients randomised to switch from their current regimen of levodopa/DDCI to either an equivalent dose of Stalevo or levodopa/DDCI plus entacapone. After 6 weeks, treatments were assessed using the Clinical Global Impression of Change, the Unified Parkinson's Disease Rating Scale and a Motor Fluctuations Questionnaire. Over 70% of patients in both the Stalevo and adjunct entacapone arms felt that they were clinically improved and over 80% experienced a reduction in fluctuations. Although there was no significant difference between Stalevo and levodopa/DDCI plus entacapone with regard to motor improvement and side effects, 81% of patients stated that they preferred treatment with Stalevo compared with taking two separate tablets (i.e. levodopa/DDCI and entacapone). Stalevo was well tolerated and safe when substituted for levodopa DDCI preparations.

Levodopa/carbidopa/entacapone (Stalevo).
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.

Determination of L-dopa, carbidopa, 3-O-methyldopa and entacapone in human plasma by HPLC-ED.
The aim of the study was the development of analytical methods suitable for the quantification of L-dopa, carbidopa and entacapone in plasma of Parkinsonian patients treated with Stalevo(®). The metabolite 3-O-methyldopa was also determined to obtain some indications on the pharmacokinetics of L-dopa. For the simultaneous analysis of L-dopa, 3-O-methyldopa and carbidopa, a RP C18 column as the stationary phase and a mixture of methanol and a pH 2.88 phosphate buffer (8:92, v/v) as the mobile phase were used. A feasible plasma pre-treatment based on protein precipitation was implemented, obtaining extraction yield higher than 94% for all the analytes. For the analysis of entacapone a RP C8 column and a mixture of methanol, acetonitrile and a pH 1.90 phosphate buffer as the mobile phase (17.5:22.5:60, v/v/v) were used. A plasma pre-treatment procedure was developed, based on solid phase extraction of entacapone using Oasis HLB cartridges. Extraction yields were good, being always higher than 96%. Both methods, based on HPLC-ED (V=+0.8V), have been fully validated. Good linearity was obtained over the following concentration ranges: 100-4000 ng mL(-1) for L-dopa, 200-10,000 ng mL(-1) for 3-O-methyldopa, 25-4000 ng mL(-1) for carbidopa and 20-4000 ng mL(-1) for entacapone. Precision data were satisfactory, being R.S.D.% values lower than 5.64%; accuracy also resulted very good with recovery data higher than 90%. The proposed methods have been successfully applied to the analysis of patient plasma samples and seem to be suitable for therapeutic drug monitoring purposes.
