Cardiovascular Research with ALZET® Pumps

Animal models of human cardiovascular disease such as those for spontaneously hypertensive rats (SHR) or balloon injury have long represented an important area of research and discovery. Whether studying hypertension, restenosis, nitric oxide (NO) and NO synthase inhibitors, or the renin-angiotensin system, the use of ALZET osmotic pumps to deliver agents continuously provides a powerful tool for experimentation. ALZET pumps have been used to deliver antihypertensive drugs, angiogenic agents, compounds which inhibit vascular restenosis, and hormones with cardiovascular effects. The reference lists* shown below contain examples of these types of research.

If you are interested in a specific agent and did not find it listed above, check the index by Agent Administered.

Pump Advantages

  • Ensure around-the-clock exposure to test agents at predictable levels
  • Permit continuous administration of short half-life proteins and peptides
  • Provide a convenient method for the chronic dosing of laboratory animals
  • Minimize unwanted experimental variables and ensure reproducible, consistent results
  • Eliminate the need for nighttime or weekend dosing
  • Reduce handling and stress to laboratory animals
  • Small enough for use in mice or very young rats
  • Allow for targeted delivery of agents to virtually any tissue
  • Cost-effective research tool

 

What researchers are saying...

“In the majority of studies examining nicotine withdrawal, nicotine was delivered y an osmotic pump... The osmotic pump allows for the continuous delivery of nicotine at a controlled rate for a specified amount of time. An advantage of this delivery protocol is that nicotine levels in the bloodstream remain fairly constant, much like those of human chronic smokers. Discontinuing the delivery of nicotine by removal of the pump or interfering with nicotine’s effect on the central nervous system induces a withdrawal reaction... Accordingly, this experiment sought to replicate previous work using a rodent model of nicotine withdrawal developed by Malin et al. (1992) that has become widely used..., and which implements the osmotic pump as the nicotine delivery mechanism.” Besheer et al., Behavioral Neuroscience 2003;117(2):327-340.
