Background:
Anastrozole is a third-generation nonsteroidal aromatase inhibitor which is used in the treatment of breast cancers. Anastrozole has also been used in the treatment of dermatomyositis skin eruptions but its direct effects on skin have not been well documented.
Objective:
To study the effects of anastrozole administration on neonatal rat skin.
Methods:
Forty Sprague-Dawley female newborn rats were separated into two control groups and two experimental groups (n = 10). One day after birth the control group of newborn rats were given daily 0.02 ml saline subcutaneously for a period of 15 days. The first experimental group of rats were treated with 0.05 mg/100g/day anastrozole subcutaneously for 15 days whereas the second experimental group of rats were given 0.25 mg/100g/day anastrozole subcutaneously for 15 days. Histopathological assessments were made and compared with the control groups.
Results:
Increased keratinization, strippling, hypertrophic epidermal cells and disorganization of the epidermal cells were observed in the first experimental group. In the second experimental group in addition to these pathologic findings acantholysis was observed.
Conclusion:
The administration of anastrazole in newborn rats showed considerable harmful effects.
Insights
Anastrozole, used for breast cancer and skin conditions, caused harmful skin changes in newborn rats. Higher doses led to more severe effects like acantholysis, indicating potential risks.
Area of Science:
- Dermatology
- Pharmacology
- Neonatal Research
Background:
- Anastrozole is a nonsteroidal aromatase inhibitor used for breast cancer treatment.
- Its effects on skin, particularly in conditions like dermatomyositis, are not well-documented.
- This study investigates anastrozole's impact on neonatal skin.
Purpose of the Study:
- To evaluate the dermatological effects of anastrozole in a neonatal rat model.
- To assess dose-dependent skin alterations induced by anastrozole.
Main Methods:
- Forty Sprague-Dawley newborn rats were divided into control and experimental groups.
- Experimental groups received daily subcutaneous anastrozole (0.05 mg/100g or 0.25 mg/100g) for 15 days.
- Histopathological analysis was performed to compare skin changes.
Main Results:
- Anastrozole administration resulted in increased keratinization, epidermal stripping, and hypertrophic epidermal cells.
- The higher anastrozole dose (0.25 mg/100g) also induced acantholysis.
- These findings indicate significant pathological alterations in neonatal rat skin.
Conclusions:
- Neonatal exposure to anastrozole causes detrimental effects on skin development.
- The observed skin pathologies suggest potential risks associated with anastrozole in neonates.
