    摘要: Compositions and methods are provided for enhanced transdermal electrotransport of 17-hydroxy sterol compounds, including testosterone. The parent sterols are modified at the 17-hydroxy position by covalent attachment of a charged chemical modifier. The chemical modifier provides the parent sterol with enhanced transport properties and is hydrolyzed under physiological conditions to release the active parent compound.The composition comprises a 17-hydroxy sterol/chemical modifier complex, more generally represented by the formula (sterol--O--)C(O)--R--N(R.sup.1)(R.sup.2)(R.sup.3).sup.+. The portion of the complex derived from the chemical modifier is indicated by "C(O)--R--N(R.sup.1)(R.sup.2)(R.sup.3).sup.+ ", where N(R.sup.1)(R.sup.2)(R.sup.3).sup.+ represents a quaternary ammonium group and R.sup.1, R.sup.2, and R.sup.3 are independently selected from the group consisting of lower alkyl, alkyl, aryl, arylalkyl, cycloalkyl, heteroalkyl, and heteroarylalkyl; or R.sup.1 and R.sup.2 together with the nitrogen to which they are attached form a substituted heterocycle and R.sup.3 is lower alkyl, and R is a linking moiety, linking the (sterol--O)--C(O)-- to the nitrogen atom.

    摘要: A heating unit comprises a substrate having a first surface and a second surface. A chemical reactant material capable of undergoing an exothermic reaction is disposed on at least a portion of the first surface of the substrate. An igniter is in proximity with the chemical reactant material. A layer of adhesive material overlays at least a portion of at least one of the chemical reactant material and the first surface of the substrate. Other embodiments of the heating unit include a first and a second substrate, each having first and second surfaces positioned with the first surfaces opposing each other in a sandwich construction. A chemical reactant material is disposed on at least a portion of the first surface of at least one of the substrates. The first and the second substrates are sealed together to define a cavity containing the chemical reactant material and an igniter is provided in proximity with the chemical reactant material.

    摘要: Aerosol drug delivery devices incorporating percussively activated heat packages are disclosed. The heat packages include a percussive igniter and a fuel capable of undergoing an exothermic oxidation-reduction reaction when ignited by the percussive igniter. The drug delivery devices disclosed can be activated by an actuation mechanism to vaporize a thin solid film comprising a drug disposed on the exterior of a hat package. Metal coordination complexes of volatile drugs, and in particular nicotine, from which the drug can be selectively vaporized when heated are also disclosed. The use of aerosol drug delivery devices comprising thin films of nicotine metal salt complexes for the treatment of nicotine craving and for effecting smoking cessation are also disclosed.

    摘要: A new reporter mechanism for biospecific reactions is disclosed. This mechanism involves interligand metal ion transfer in which a metal ion is directly transferred from one chelate complex to another following the occurance of the biospecific reaction. The second chelate complex is separate from and detectably different than the first chelate complex. This invention can take the form of methods of chemical analysis and kits for conducting such methods. In preferred embodiments of this invention the detectable difference is a difference in fluorescence, such as an increase or decrease which occurs as a result of the formation of the second chelate. In further preferred embodiments the difference in fluorescence is detected using fluorescent background rejection methods.
