Materials and Methods instrument A Hewlett-Packard HP ; Palo Alto, CA ; 5890 gas chromatograph with splitless injection and a 5970 mass selective detector were used. The capillary column used was a J&W Scientific Folsom, CA ; DB-1 [15 m 0.32 mm i.d. ; , 0.25- m-thick film]. Helium was the carrier gas at a flow rate of 0.7 mL min and a linear velocity of 38 cm The temperature program was: initial temperature, 150 C for 1.5 min; ramp at 20 C min to 250 C; injection temperature, 250 C; and transfer line, 280 C. materials Codeine, morphine, hydrocodone, and hydromorphone used to prepare calibrators and controls were obtained from Sigma Chemical Co. St. Louis, MO ; and Radian Austin, TX ; . Deuterated codeine, morphine, hydrocodone, and hydromorphone used as internal standards ; and oxycodone, oxymorphone, and norcodeine used for interference studies ; were obtained from Radian. Hydroxylamine hydrochloride and Helix pomatia type H-2 ; -glucuronidase were obtained from Sigma Chemical Co. BSTFA with 10 mL L trimethylchlorosilane TMCS ; was from Regis Chemical Co. Morton Grove, IL ; . All other solvents and reagents were of reagent or HPLC-grade. extraction and derivatization A 2.0-mL volume of urine calibrators, controls, samples ; was combined with 100 L of a mg L internal standard solution deuterated codeine, morphine, hydrocodone, and hydromorphone ; and 100 L of 2.0 mol L acetate buffer pH 4.8 ; in an appropriately labeled 16 100 mm screw cap tube. All samples were vortex-mixed. Conjugates were hydrolyzed by the addition of 100 L of -glucuronidase solution 99.2 U L ; to all calibrators, controls, and donor samples and incubation at 56 C for 2 h. After hydrolysis, extraction derivatization of ketoopiates was performed by the addition of 100 L of aqueous hydroxylamine 100 g L ; to each tube, then heating for 15 min at 56 C. All tubes were centrifuged, and the supernatant was placed on solid-phase bonded silica extraction columns [Varian Palo Alto, CA ; Bond ElutTM or United Chemical Technology Bristol, PA ; Clean ScreenTM], previously activated by the sequential addition and elution of 3 mL both methanol and and prednisone. The formation of oxymorphone, but not noroxycodone, is mediated by cytochrome p450 2d6 and, as such, its formation can, in theory, be affected by other drugs see drug-drug interactions. Department of Pharmaceutical Sciences, College of Pharmacy, University of Kentucky, Lexington, KY In the United States, oxycodone is available exclusively as oral formulations.4 In some cases, however, the oral route might not be the best choice for the patient, owing to difficulties with swallowing, or when a faster onset of action is required. Furthermore, parenteral administration may not offer a suitable alternative, owing to decreased venous access. In recent years a growing interest in alternative dosage forms for drug administration has emerged. Accordingly, other novel routes of drug administration have been investigated. In this respect, oxycodone has been administered to humans intramuscularly, 5 intranasally, 6 orally using immediate release solutions or as tablets and controlled-release tablets, 7-9 subcutaneously, 10 and rectally.11 The rectal administration may result in greater variability compared with oral administration, and while the transdermal route may result in minimal presystemic hepatic elimination, it may exhibit a slow onset of action. Drug delivery via the oral mucous membranes is considered to be a promising alternative to the oral route. In terms of permeability, the sublingual area of the oral cavity ie, the floor of the mouth ; is more permeable than the buccal cheek ; area, which in turn is more permeable than the palatal roof of the mouth ; area.12 These differences in permeability are generally based on the relative thickness, the blood supply, and degree of keratinization of these membranes. In addition to the differences in the permeability of the various mucous membranes, the extent of drug delivery is also affected by the physicochemical properties of the drug to be delivered. The sublingual route physiological pH ~6.5 ; 13 has the potential for providing an alternative to intravenous dosing for rapid delivery of drugs to the systemic circulation. Sublingual drug delivery bypasses gastrointestinal and hepatic presystemic elimination and is an acceptable form of drug delivery applicable in patients with swallowing problems. Furthermore, the high potency of oxycodone makes it suitable for sublingual delivery, owing to limitation in the dose that can be administered. Also, sublingual drug administration is simple and relatively cost-effective. The purpose of this study was to develop a sublingual spray drug delivery formulation of oxycodone for acute pain management, using rabbit as the animal model, and to evaluate the effect of formulation pH on the sublingual absorption of oxycodone.
