Furthermore, BEC is a slow-binding inhibitor of arginase, which is still in the preclinical stage (Pudlo et al., 2017)

Notably, two such trials with low dose NAC, 600 mg/day over 3 years demonstrated some efficacy in inhaled corticosteroid (ICS)-nave patients only ( High-dose NAC (1,200 mg/day) showed superior outcomes, improving lung volumes [Forced Vital Capacity (FVC), Residual Volume/ Total Lung Capacity (RV/TLC), Inspiratory Capacity (IC)] and exercise tolerance( 2575% ), reactance at 6 Hz, and resonant frequency over 1 year, while these declined with placebo ( The PANTHEON trial, a large double-blind RCT in GOLD defined COPD patients with severe airflow obstruction and a history of 2 COPD exacerbations in the previous year, found that NAC 600 mg BID reduced exacerbation rates in NAC group (497 acute exacerbations in 482 patients, 1.16 AcEx/pt/yr) versus placebo (641 acute exacerbations in 482 patients, 1.49 AcEx/Pt/yr), p 1 log 10 ) compared to untreated controls (67)
For best results, consider taking both on an empty stomachespecially before bedso they can work in harmony and deliver maximum benefits
Compared with the COPD rats treated with NAC + oe-VWF + sh-NC, levels of IL-6 and TNF- elevated in serum of COPD rats treated with NAC + oe-VWF + sh-p38 MAPK (Fig
