Comparative Stability of Compounded Omeprazole Suspension Versus Commercial Omeprazole Kit When Stored in Oral Syringes Under Refrigerated Conditions.

Omeprazole is a proton pump inhibitor used to manage gastrointestinal disorders. Special populations may require omeprazole to be given as an oral suspension. The purpose of this project was to compare the stability of omeprazole in the FIRST kit product to a traditionally compounded omeprazole suspension, when stored in refrigerated unit-dosed syringes.

Labelling accuracy in low nicotine e-cigarette liquids from a sampling of US manufacturers.

Objectives: To assess labelling accuracy for low nicotine concentration e-cigarette liquids.

Methods: Nicotine concentration in twelve e-liquids, available in 3 and 6 mg/ml strengths, was assayed (5 replicates each) using liquid chromatography-tandem mass spectrometry.

Key Findings: Average nominal concentrations of nicotine were lower than reported in 23/24 products tested, with 2/12 products labelled 3 mg/ml, and 3/12 of the 6 mg/ml products showing statistically significant differences from controls.
