Route of Agent Administration

ALZET minipumps can be used for systemic administration when implanted subcutaneously or intraperitoneally. They can be attached to a catheter for intravenous, intra-arterial, or intrathecal infusion. ALZET pumps can also be cannected to brain cannulae for delivery to the cerebral ventricles or brain tissue. ALZET pumps have been used for targeted delivery of test agents to a wide variety of sites, including the spinal cord, spleen, liver, organ or tissue transplants, wound healing sites, etc.

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...

“We found recently that 21 d of treatment of rats with SSRIs, at clinically relevant and stable serum concentrations (achieved by the use of osmotic minipumps), caused robust downregulation of the SERT.”... “Studies on the effects of chronic antidepressants on the SERT have resulted in inconsistent reports (Owens and Nemeroff, 1998). Among the factors that may contribute to such inconsistency is the route of drug administration. In most studies of chronic administration of Ads to rats, the drugs are given intraperitoneally or subcutaneously, either once or twice daily. As rats metabolize these drugs more rapidly than humans, such dosage schedules can result in appreciable fluctuations in the serum concentration of drug throughout the day. For certain pharmacologic effects, sustained drug action may be needed” Benmansour et al. The Journal of Neuroscience 2002; 22(15):6766-6772.
