| | Naloxone hydrochloride dihydrate Usage And Synthesis |
| Chemical Properties | White or almost white, hygroscopic, crystalline powder. | | Uses | Antagonist (to narcotics). | | Uses | Naloxone Hydrochloride Dihydrate is a specific opioid antagonist. Narcotic antagonist. | | Brand name | Narcan (Bristol-Myers Squibb); Narcan (Endo). | | Biochem/physiol Actions | Competitive antagonist for μ, κ, δ, and σ opioid receptors; blocks the action of σ-agonists at opioid sites. Naloxone′s antagonistic effect last for about 45 min and thus, requires repeated dosage. It results in critical side effects such as pulmonary edema. | | Purification Methods | This opiate antagonist has been recrystallised from EtOH/Et2O or H2O. It is soluble in H2O (5%) and EtOH but insoluble in Et2O. The free base has m 184o (177-178o also reported) after recrystallisation from EtOAc, and [] D -194.5o (c 0.93, CHCl3). [Olofson et al.
