Monocrotaline-induced pulmonary hypertension


To assess the effect of antihypertensive agents on pulmonary artery pressure and right ventricular hypertrophy


Single injection of monocrotaline (MCT); a pyrrolizidine alkaloid which leads to endothelial dysfunction and damage associated with clinical pathogenesis of PAH in human. Severe PAH is observed after 28 days following the MCT injection.

Study Outcome

  • Hemodynamic parameters; mPAP, mSAP, RVSP, Pulse Pressure, PVR, Heart rate, saturation
  • Fulton’s index, Lung weight
  • Cardiac function parameters obtained by echocardiography; CO, SV, PAAT, Vmax, VTI, RV free wall thickness







We help you design the study you need.

At IPST we rise to the challenge of designing out-of-the-box inventive studies with new endpoints, novel routes of administration and pioneering models.

At IPST we recognize the need to customize every preclinical assay in order to maximize its predictivity.

Scientist Director

Charles-E. Laurent

Ph.D., Director of In-Vivo Pharmacology

“Over the past 13 years, I had the greatest opportunity to exploit my passion for science at IPST by contributing to the design, and validation of unique assays which are now routinely run and serve to quantify the efficacy in preclinical drug candidates. My greatest contribution was to see the increase in demand for efficacy services such as the rodent model of pulmonary arterial hypertension (PAH), as well as our intravascular thrombosis and hemostasis models.” Charles completed his doctorate in Pharmacology at the Université de Montreal followed by 4 years of post doctorate studies at the University of Pittsburgh in the Department of Molecular Genetics and Biochemistry. His field of expertise includes cardiovascular pharmacology and molecular biology.
