ALZET® Osmotic Pumps

DURECT manufactures and sells ALZET Osmotic Pumps and accessories on a worldwide basis. We market the ALZET product line directly in the U.S. and through a network of distributors outside the U.S.

The ALZET product line consists of miniature implantable pumps and a range of accessories for experimental research in mice, rats, and other laboratory animals. ALZET pumps continuously deliver drugs, hormones, and other test agents at controlled rates for durations ranging from 1 day to 6 weeks. They eliminate the need for external connections, frequent handling, or repeated dosing. In laboratory research, these infusion pumps can be used for systemic administration when implanted under the skin or in the body. They can also be attached to a catheter for intravenous, intracerebral, or intra-arterial infusion, or for targeted delivery, where the goal is to localize the effects of a drug or test agent to a particular tissue or organ. The wide use and broad application of the ALZET product line is evidenced by more than 16,000 references in the scientific literature.

ALZET pumps are neither approved nor intended for human use.
