Summary

Dr. David Rosenblum delivered a comprehensive lecture on gender differences in opiate effects and prescribing practices. He discussed several key studies examining how opiates affect males and females differently, both in animal models and humans. Dr. Rosenblum shared findings showing that morphine has stronger analgesic effects in males, while females experience longer-lasting effects. He also addressed racial disparities in opiate prescribing, noting that white patients are more likely to receive opiates. From his personal clinical experience in Brooklyn, Dr. Rosenblum observed that certain populations tend to be at higher risk for opiate abuse. The lecture covered gender-specific risk factors for opiate misuse, with women tending toward emotional/psychological factors and men showing more behavioral issues.

Dr. Rosenblum discussed his role in board preparation through painxam.com and nreppain.org. He emphasized that opiates are a frequently tested topic across different board examinations (FIP, ABPM, ABIP, ABA).

Gender Differences in Opiate Effects - Animal Studies

Dr. Rosenblum presented research showing that in animal studies, morphine exhibited stronger analgesic effects in males, while females showed longer-lasting effects and could tolerate higher doses. He noted that physical dependence was more severe in male rats during spontaneous withdrawal.

Racial and Gender Disparities in Opiate Prescribing

Dr. Rosenblum discussed a 2025 study revealing racial disparities in opiate prescribing, with white patients more likely to receive opiates. He shared his personal clinical experience in Brooklyn, noting that young white males were often higher-risk for abuse.

Gender-Specific Risk Factors for Opiate Misuse

Dr. Rosenblum detailed how women tend to show emotional and psychological risk factors for opiate misuse, while men demonstrate more behavioral risk factors. Women were more likely to report distress and past trauma, while men showed higher rates of criminal behavior and substance abuse history.
