Just wondering.
IMO (and I could be wrong), but I think it would be the opposite - it would increase Cardiotoxicity if anything.Just wondering.
Ah gotcha.Yes, but only partially—and only in certain situations.
Amphetamine isn’t uniquely cardiotoxic. Like most stimulants, it stresses the heart mainly by activating the sympathetic nervous system (SNS). This means increased heart rate, higher blood pressure, and vasoconstriction. Over time, or in a massive overdose, this can strain the heart and circulation, sometimes leading to arrhythmias, heart attacks, or long-term heart muscle problems.
Amphetamine can also be directly toxic to heart cells, especially with chronic or high-dose use. It can cause oxidative stress, damage mitochondria, and contribute to structural changes in the heart (remodelling), which can eventually lead to cardiomyopathy. This is most well-documented with heavy methamphetamine use; standard prescription doses or infrequent use are much less risky in healthy hearts.
Benzodiazepines do reduce CNS and SNS activity, which can lower heart rate and blood pressure in the short term. However, they don’t protect against the direct, long-term damage amphetamine can cause to heart cells.
Practically speaking, benzodiazepines also blunt the psychoactive effects of amphetamine. So if the goal is reducing heart strain, a much safer strategy is simply using less amphetamine, rather than relying on a benzo to “protect” your heart.
