Bupivacaine
Bupivacaine has been studied in 4 papers since 2016: 2 trials in people, 1 in cells, 1 review. The newest paper, Oct 21, 2025: “Surgical site injection of liposomal bupivacaine reduces 90-day incidence of major complications after hip fracture: a nonrandomized trial”.
“Patients in the LB group had a reduced incidence of major complications within 90 days [19 (14.2%) patients vs. 167 (24.6%) patients] compared with patients in the control group, with an adjusted hazard ratio (HR) of 0.55 [95% confidence interval (CI) 0.34-0.89, P = .014].”

What did lifespan studies of Bupivacaine find?
DrugAgeDrugAge records 4 results from 1 paper: 2 in C. elegans and 2 in D. melanogaster. Average lifespan is the mean or the median, as each paper reports it.
What did studies of Bupivacaine find?
3Studies of Bupivacaine measured 3 outcomes; the most studied are delirium (1 study), weight bearing (1) and mortality (1).
Delirium
no changein humans1
1 study
Delirium
no changein humans1
Bupivacaine has no effect on delirium in humans (4.5% vs 7.2%, P = 0.254).
“The incidence of delirium was similar between the two group [LB group 6 patients (4.5%) vs. control group 49 (7.2%) patients, P = 0.254].”

Weight bearing
upin humans1OR 2.4
Bupivacaine improves weight bearing in humans (OR 2.40 (1.64-3.51), 54.5% vs 33.1%).
“Seventy-three patients in the LB group (54.5%) achieved weight-bearing within 24, while 225 patients in the control group (33.1%) achieved this goal, with an odds ratio of 2.40 (1.64-3.51, P < 0.001).”

Mortality

Bupivacaine has no effect on mortality in humans (HR 0.74 (0.35-1.56), 6.0% vs 8.5%).
“death occurred in 8 (6.0%) patients of the LB group and 58 (8.5%) of the control group, with an HR of 0.74 (0.35-1.56, P = 0.432).”

What is Bupivacaine linked with?
1Studies link Bupivacaine with 1 measure, most often major complications (1 study).

Major complications

Bupivacaine lowers the risk of major complications in humans (adjusted HR 0.55 (95% CI 0.34-0.89), 14.2% vs 24.6%).
“Patients in the LB group had a reduced incidence of major complications within 90 days [19 (14.2%) patients vs. 167 (24.6%) patients] compared with patients in the control group, with an adjusted hazard ratio (HR) of 0.55 [95% confidence interval (CI) 0.34-0.89, P = .014].”
