Researchers in Italy have identified a possible connection between the erectile dysfunction drug Cialis (tadalafil) and muscle regeneration. The findings were published in the journal Molecular Biology Reports. In the study, the drug was tested on mouse muscle cells in a laboratory setting.
Over a span of seven days, researchers examined tadalafil’s impact on muscle cell growth, survival, and development. They observed an increase in muscle precursor cells, which are crucial in the early stages of muscle formation, along with an improvement in their survival rates. The drug also aided muscle repair by fostering growth and minimizing cell death.
Despite these promising insights, tadalafil appeared to delay the development of fully mature muscle cells. This suggests that while the drug may help create and sustain cells for muscle regeneration, it doesn’t necessarily enhance muscle size or function in humans.
The research was limited by its use of mouse models, indicating potential differences when applied to human subjects. Additionally, the study’s duration of just seven days highlights the need for further investigation to understand long-term effects.
Dr. Cristina Antinozzi, a study co-author and researcher at the University of Rome Foro Italico, described the findings as an “encouraging look at how tadalafil might be repurposed to support muscle tissue repair and regeneration.” However, she emphasized the necessity of more research to confidently determine the drug’s effects on people. She also noted the importance of monitoring the potential misuse of such mechanisms in sports and performance contexts.
Dr. Kien Vuu, a radiologist and founder of VuuMD Performance and Longevity in Los Angeles, acknowledged the study as an “intriguing early finding.” He noted that while tadalafil aided muscle precursor cell growth and survival, it also hindered their maturation into muscle fibers. Vuu pointed out that successful muscle regeneration requires cell maturation to form functional tissue, a step not established in this experiment.
From a longevity perspective, Vuu believes this area is “worth studying” since age-related muscle loss contributes significantly to frailty, metabolic dysfunction, and loss of independence. However, he stressed the importance of reliable practices such as resistance training, adequate protein intake, and quality sleep for muscle protection as people age.
Vuu warned against the premature use of tadalafil for muscle-building based on these preliminary findings. He cautioned about the risks associated with tadalafil, especially the potential for dangerous blood pressure reductions when combined with nitrates.
