Objectives: The aim of this study was to evaluate the efficacy of various bowel preparations in accomplishing colonic cleansing for optimal mucosal visualization during colonoscopy.
Methods: The study included a cohort of 980 patients who underwent colonoscopy at our endoscopy center within the last 3 years. All of the study patients were subdivided into four groups. Each group included 245 patients, all receiving a different type of bowel preparation. The bowel preparations used in this study included: magnesium citrate (Group I), a combination of oral sodium phosphate (fleets) and powder PEG-3350 (Group II), powder polyethylene glycol-3350 (PEG-3350 powder for Group III), and oral sodium phosphate (fleets for Group IV). A Colon Prep Score (CPS) was devised to compare the quality of the different bowel preparations used. The colonoscopy results from all of these patients were tabulated and analyzed statistically and expressed as mean ± 1 standard deviation. Statistical analysis was performed using a one way ANOVA with Holm-Sidak method for intergroup analysis.
Results: Group I patients received magnesium citrate and had a mean CPS ± 1 SD of 3.11 ± 0.91. Group II patients (fleets and powder PEG-3350 combination) achieved a CPS of 3.37 ± 1.16. The patients in Group III (powder PEG-3350) actually showed the highest mean CPS of 3.44 ± 1.12. Group IV patients who used oral sodium phosphate alone reached a mean CPS of 3.23 ± 1.01. Group III patients (powder PEG-3350 only) demonstrated a statistically higher CPS (P<0.0006) in colon cleansing as compared to Group I patients (magnesium citrate). Similarly, Group II patients (oral sodium phosphate and powder PEG-3350 combination) also showed improved colon cleansing statistically (P<0.006) as compared to Group I patients (magnesium citrate).
Conclusions: Overall, all four colon preparations achieved an average CPS greater than 3.0 indicating clinically adequate colonic cleansing. However, powder PEG-3350 alone and in combination with oral sodium phosphate was observed to be statistically superior to magnesium citrate, when used for colon preparation for colonoscopy.

PARPi-FL is a molecularly specific fluorescent agent that targets poly ADP-ribose polymerase 1, a DNA repair enzyme overexpressed in the nuclei of tumor cells. This imaging agent is being investigated in a clinical trial (NCT03085147) for the detection of oral cancer. The PARPi-FL mouthwash formulation currently being used in the phase I/II clinical trial comprises 1,000 nM of PARPi-FL dissolved first in 4.

This review identified 126 commercially available antibodies approved globally between 1986 and February 2021 including 10 antibody drug conjugates, 16 biosimilars, and 3 antibody fragments. Prior to 2014 there were ≤ 5 approved each year, but after 2014 there have been ≥ 7 approved each year with the years 2017, 2019 and 2020 having the most at 17 each. A total of 136 products were identified of which 36 are lyophilized powders and 100 are solutions.

Purpose: To study and elucidate the effect of the intensity and duration of processing stresses on the possible solid-state changes during a hot melt extrusion granulation process.
Methods: Blends of α-indomethacin and PEG 3350 (w/w 4:1) were granulated using various screw sizes/designs on the melt extruder under different temperature regimes. Differential Scanning Calorimetry and X-ray Powder Diffraction were employed for characterization.

The purpose of this work was to investigate the application of different advanced continuous processing techniques (hot melt extrusion and spray drying) to the production of fixed-dose combination (FDC) monolithic systems comprising of hydrochlorothiazide and ramipril for the treatment of hypertension. Identical FDC formulations were manufactured by the two different methods and were characterised using powder X-ray diffraction (PXRD) and modulated differential scanning calorimetry (mDSC). Drug dissolution rates were investigated using a Wood's apparatus, while physical stability was assessed on storage under controlled temperature and humidity conditions.

Objectives: Electrolyte-free polyethylene glycol powder (PEG-3350) has been widely used for colonoscopy preparation (prep); however, limited safety data on electrolyte changes exists with 1-day prep regimens. The primary aim of this study was to determine the proportion of patients with significant serum chemistry abnormalities before and at the time of colonoscopy. Secondary aims included evaluation of prep tolerance and bowel cleansing efficacy.
