Timeline of Regulatory Milestones 2005: Exenatide (Byetta): First GLP-1 agonist approved, twice-daily injections 2010: Liraglutide (Victoza): Longer-lasting, once-daily injection 2014: Dulaglutide (Trulicity): Once-weekly injection arrives 2017: Semaglutide (Ozempic): First once-weekly injection for diabetes with powerful weight-loss effects 2019: Oral semaglutide (Rybelsus): First GLP-1 pill makes it past the stomachs defenses 2021: High-dose semaglutide (Wegovy): FDA approval for obesity treatment 2022: Tirzepatide (Mounjaro): First dual GLP-1/GIP agonist for diabetes 2023: Tirzepatide (Zepbound): Expanded approval for obesity 20232024 : Widespread shortages: Skyrocketing demand for GLP-1s leads to limited availability The shortage that began in late-2023, driven by soaring off-label demand and supply-chain bottlenecks left millions of patients unable to fill even maintenance scripts
Below is a snapshot of some supporting research: In one very small study on five people with mild to moderate Parkinsons disease and three controls, a high dose of NAC (a total of 6,000 mg/day taken orally which diminished the bioavailability of the dose) for a period of 4 weeks led to an increase of cysteine levels and antioxidant measures (GSH/GSSGa ratio of the reduced to oxidized glutathione which relates to oxidative stress with higher ratio levels associated with healthier cellsand catalase), but it did not demonstrate any improvement in the oxidative stress measurements (4HNE and MDA) nor did it increase the level of glutathione in the brains
These typically resolve within 8 to 24 hours but can lead to clinically significant complications, including dehydration, acute kidney injury, and electrolyte abnormalities
