Abstract:
Abiraterone and enzalutamide are in widespread clinical use because of their favorable safety and efficacy. Nonetheless, even with newer agents, resistance develops overtime. In this review, we discuss mechanisms of resistance to these newer agents as well as novel therapeutic agents. We also review the literature to help clinicians decide which agent to begin with and when to stop or switch androgen receptor agents.
Insights
Abiraterone and enzalutamide are effective but resistance develops. This review covers resistance mechanisms, new therapies, and guidance on using androgen receptor agents in prostate cancer treatment.
Area of Science:
- Oncology
- Pharmacology
- Urology
Background:
- Abiraterone and enzalutamide are widely used for prostate cancer due to safety and efficacy.
- Resistance to these androgen receptor–targeted therapies is a significant clinical challenge.
Purpose of the Study:
- To review mechanisms of resistance to abiraterone and enzalutamide.
- To discuss novel therapeutic agents for overcoming resistance.
- To provide clinical guidance on the use of androgen receptor agents.
Main Methods:
- Literature review of mechanisms of resistance.
- Review of novel therapeutic agents.
- Analysis of clinical decision-making for androgen receptor agents.
Main Results:
- Resistance mechanisms to newer agents are complex and varied.
- Novel therapeutic agents show promise in preclinical and early clinical studies.
- Evidence-based recommendations for agent sequencing and discontinuation are needed.
Conclusions:
- Understanding resistance mechanisms is crucial for developing effective treatment strategies.
- New therapeutic agents offer potential for improved outcomes in resistant prostate cancer.
- Clinical guidelines are essential for optimizing the use of androgen receptor agents.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
