How is fentanyl activated?
Volunteers were administered naltrexone to antagonize the opioid effects of fentanyl. Absorption At the initiation of each dose, an electrical current is activated, which moves a dose of fentanyl from the drug-containing reservoir through the skin and into the systemic circulation.
How do you give a fentanyl infusion?
Fentanyl 50 micrograms/ml Solution for Injection/Infusion may also be administered as an intravenous infusion. Ventilated patients may be given a loading dose as a fast infusion of approximately 1 microgram/kg/minute for the first 10 minutes, followed by an infusion of approximately 0.1 microgram/kg/minute.
Can iontophoresis deliver clinically significant doses of fentanyl in humans?
Although this study demonstrates that iontophoresis can be used to deliver clinically significant doses of fentanyl in humans, the pharmacokinetics of this system should be defined more clearly.
What is the potential of iontophoresis in transdermal delivery?
The potential of iontophoresis has been exploited for the transdermal delivery of many drugs with poor penetration properties e.g., high molecular weight electrolytes such as proteins, peptides and oligonucleotides which are normally difficult to administer except through parenteral route.
What is the role of iontophoresis in Drug Administration?
Iontophoresis may be used as a route of administration for systemic drugs or as local therapy. Indeed, cutaneous iontophoretic delivery is faster than the usual topical routes and allows the administration of high concentrations in the target tissue while limiting systemic toxicity.
Is iontophoresis safe and effective?
Iontophoresis is safe, effective and inexpensive. Battery-powered direct current (DC) and mains-powered alternating current (AC) iontophoresis devices are available. Individual machines vary, and the instructions provided by the manufacturer should be followed carefully. Two mechanisms are involved in iontophoretic transport.
