Levodopa Equivalent Dose Conversion Factors: An Updated Proposal Including Opicapone and Safinamide

A proposal for an updated neuropsychopharmacological nomenclature

Current psychopharmacological nomenclature remains wedded in an earlier period of scientific understanding, failing to reflect contemporary developments and knowledge, does not aid clinicians in selecting the best medication for a given patient, and tends to confuse patients by prescribing a drug that does not reflect their identified diagnosis (e.g. prescribe "antipsychotics" to depression). F...

Spotlight on opicapone as an adjunct to levodopa in Parkinson’s disease: design, development and potential place in therapy

Parkinson's disease (PD) is a progressive, chronic, neurodegenerative disease characterized by rigidity, tremor, bradykinesia and postural instability secondary to dopaminergic deficit in the nigrostriatal system. Currently, disease-modifying therapies are not available, and levodopa (LD) treatment remains the gold standard for controlling motor and nonmotor symptoms of the disease. LD is exten...

Randomized trial of safinamide add-on to levodopa in Parkinson's disease with motor fluctuations

Levodopa is effective for the motor symptoms of Parkinson's disease (PD), but is associated with motor fluctuations and dyskinesia. Many patients require add-on therapy to improve motor fluctuations without exacerbating dyskinesia. The objective of this Phase III, multicenter, double-blind, placebo-controlled, parallel-group study was to evaluate the efficacy and safety of safinamide, an α-amin...

Estimation of dose conversion factors Conversion factors from measurable to risk related quatities

Interventional cardiovascular procedures in Belgium: effective dose and conversion factors.

Effective dose (E), representing the risk of late radiation-induced effects, can be estimated by the use of conversion factors (CF), converting direct measurable quantities such as dose-area-product into E. Eight Belgian hospitals participated in the study with a total number of 318 procedures. E-values, calculated with PCXMC, were compared for the different hospitals for diagnostic and therape...
