Semiquantitative sensitization safety assessment of extractable and leachables associated with parenteral pharmaceutical products

Extractable and leachables (E&Ls) associated with parenteral pharmaceutical products should be assessed for patient safety. One essential safety endpoint is local or systemic sensitization. However, there are no regulatory guidelines for quantitative sensitization safety assessment of E&Ls. A semiquantitative sensitization safety assessment workflow is developed to refine the sensitization safety assessment of E&Ls associated with parenteral pharmaceutical products. The workflow is composed of two sequential steps: local skin sensitization and systemic sensitization safety assessment. The local skin sensitization step has four tiers. The output from this step is the acceptable exposure level for local sensitization (AEL_ls) and this safety threshold can be used for local sensitization safety assessment. From the derived AEL_ls, the systemic sensitization safety assessment at step 2 proceeds in 2 tiers. The output from this workflow is the derivation of acceptable exposure level for systemic sensitization (AEL_ss). When the estimated human daily exposure (HDE) is compared with the AEL_ss, the margin of exposure is calculated to determine the sensitization safety of E&Ls following parenteral administration. The current work represents an initial effort to develop a scientifically robust process for sensitization safety assessment of E&Ls associated with parenteral pharmaceutical products.

Perception and attitude of adults toward cosmetic products amid COVID-19 pandemic in Malaysia

BACKGROUND

The use of cosmetics is growing among both male and female consumers due to the availability of different brands. While there is an increase in the usage of cosmetic products, it is concerning whether the consumers are aware of the safety of the products.

AIMS

This study aimed to widely explore consumers' perceptions and attitudes toward cosmetics within the context of the COVID-19 pandemic.

METHODS

A cross-sectional study was carried out among adults in Selangor, Malaysia. Thirty-three questions divided into three dimensions (socio-demographic parameters, assessment of perception, and assessment of attitude) were developed and validated to be answered by cosmetics consumers. Descriptive and inferential statistical analysis was done using SPSS.

RESULTS

A response rate of 87% was achieved, and the mean age of participants was 33 ± 7.2. The overall perception of consumers indicates low levels of perception and moderate level of attitude toward cosmetic products. There was a positive correlation and high relationship between participants' perception and attitude (p = 0.001, r = 0.72). A significant association was observed between demographic data of respondents and their attitude and perception toward cosmetic products. Participants were unaware that sharing of cosmetic products could lead to bacterial infection and possibly increased the chance of contracting COVID-19.

CONCLUSION

This study displayed a nonchalant perception and attitude of Malaysian adults toward cosmetic products by focusing on aesthetics rather than health safety. Therefore, it is recommended to raise awareness on the composition and effects of cosmetic products, increase the practice of hygiene and dissuade the sharing of cosmetics to reduce transmissions of COVID-19.
