Video abstract of original research paper “Stability of apomorphine in solutions containing selected antioxidant agents” published in the open access journal Drug Design, Development and Therapy by authors Ang, Boddy, Liu et al.

Abstract: Apomorphine in solution undergoes rapid autoxidation, producing greenish colored solutions, making it difficult to formulate as a stable pharmaceutical solution. To identify the optimum antioxidant agent/combination for apomorphine solution, a high performance liquid chromatography assay was used to study the stability of 50 µg/mL apomorphine HCl in 0.1% L-ascorbic acid (AA), 0.1% sodium metabisulfite (SMB), 0.1% EDTA, and in selected combinations at 25°C, 32°C, and 37°C over a period of 14 days. The stability of apomorphine HCl (10 mg/mL) in 0.1% AA solution and in 0.1% EDTA solution at 25°C and 37°C was also evaluated. Apomorphine HCl solution (50 µg/mL) in 0.1% AA plus 0.1% SMB solution retained 99.7% (at 25°C) and 95.9% (at 37°C) of the initial concentration, as 0.1% AA plus SMB solution minimized the reactive oxygen content in solution which, in turn, reduced the oxidation rate of apomorphine HCl, and there was no green coloration perceptible. Conversely, apomorphine HCl solution (50 µg/mL) in 0.1% SMB solution was unstable as only 0.53% (at 25°C) and 0.06% (at 37°C) of the initial concentration was retained after 14 days. All 10 mg/mL apomorphine HCl samples were stable in both studies. The initial concentration of apomorphine HCl solution markedly affected its rate of oxidation and discoloration. The addition of 0.1% AA to a current formulation of apomorphine HCl injection (Apomine®), which contains SMB as an antioxidant, was recommended as providing the most stable solution.

Antioxidants and Types of antioxidant systems

This video explains about Antioxidants and Types of antioxidant systems.

Antioxidants acts at different levels by:

Preventing the initiation of chain reactions by removing free radicals.

Interrupting chain sequence, Scavenging free radicals generated in chain reaction.

Removing peroxidases, thereby preventing further generation of reactive oxygen species (ROS).

There are three main types of antioxidant systems:

Enzymes antioxidant system

2. Vitamins antioxidant system

3. Minerals antioxidant system
