What’s Alfenta (Alfentanil)? Buy Alfenta (Alfentanil) online without prescription

Alfentanil (R-39209, trade name Alfenta, Rapifen in Australia) is a potent but short-acting synthetic opioid analgesic drug, used for anaesthesia in surgery. It is an analogue of fentanyl with around 1/4 to 1/10 the potency of fentanyl and around 1/3 of the duration of action, but with an onset of effects 4x faster than fentanyl. Alfentanil has a pKa of approximately 6.5, which leads to a very high proportion of the drug being uncharged at physiologic pH. This unique characteristic is responsible for its rapid onset. It is an agonist at mu opioid receptors.


ALFENTA (alfentanil) is indicated:

  • as an analgesic adjunct given in incremental doses in the maintenance of anesthesia with barbiturate/nitrous oxide/oxygen.
  • as an analgesic administered by continuous infusion with nitrous oxide/oxygen in the maintenance of general anesthesia.
  • as a primary anesthetic agent for the induction of anesthesia in patients undergoing general surgery in which endotracheal intubation
  • and mechanical ventilation are required.
  • as the analgesic component for monitored anesthesia care (MAC).
