Purpose: Doxecitine (deoxycytidine [dC]) and doxribtimine (deoxythymidine [dT]) powder for oral solution is a 1:1 mixture consisting of equal weights 2'-deoxycytidine (dC) and 2'-deoxythymidine (dT). Doxecitine and doxribtimine (referred to as study drug) is being developed as treatment for people with thymidine kinase 2 deficiency (TK2d). TK2d is an ultra-rare mitochondrial DNA depletion and multiple deletion syndrome characterized by progressive muscle weakness and premature death.

Fenfluramine is extensively metabolized; thus, patients with hepatic impairment (HI) might experience changes in exposure to fenfluramine or its metabolites. In this phase 1 study, we investigated the pharmacokinetics (PK) and safety of a single oral dose of 0.

The pharmacodynamics and efficacy of IPX203 were compared with immediate-release carbidopa-levodopa (IR CD-LD) in this open-label, rater-blinded, multicenter, crossover study in patients with advanced Parkinson disease (PD).
Methods: Twenty-eight patients were randomized to 2 weeks of treatment with IR CD-LD followed by IPX203 or IPX203 followed by IR CD-LD.
Objective: IPX203 is an investigational oral extended-release capsule formulation of carbidopa-levodopa (CD-LD). The aim of this study was to characterize the single-dose pharmacodynamics, pharmacokinetics, and safety of IPX203 in subjects with advanced Parkinson disease compared with immediate-release (IR) CD-LD and extended-release CD-LD (Rytary).
Methods: This was a randomized, open-label, rater-blinded, multicenter, single-dose crossover study.

Background And Objective: Nefopam is a non-opioid, non-steroidal, central analgesic thought to act via multiple mechanisms including potent inhibition of serotonin-norepinephrine reuptake and modulation of voltage-sensitive calcium and sodium channels. There has been a resurgence in its use for postoperative pain and neuropathic pain. Dosing route-dependent metabolism and clinical effects have been described following intravenous and oral nefopam.
