摘要:
A topical spray or foam, methods of making the formulation, and methods of use thereof, has been developed. In one preferred embodiment, the composition includes one or more active agents and exhibits both antibacterial activity and antifungal activity. Excipients such as chemical disinfectants, anti-pruritic agents to minimize itching, and skin protective compounds may be added. The composition may be formulated to be dispensed as a spray or foam and the spray or foam may be administered either by a hand pump or by an aerosolizing propellant. A second single phase formulation has also been developed. The formulation comprises a first drug which is water soluble or hydrophilic and a second drug which is lipid soluble or hydrophobic, wherein at least one of the drugs is bound to an ion-exchange resin. The use of binding resins, such as ion-exchange resins, allows drugs with incompatible solvent requirements to be prepared in a single-phase formulation.

The invention includes an apparatus and method for transdermal delivery of bupropion base. In the method of this invention, patient is administered parenterally a bupropion base in an amount effective to alleviate withdrawal symptoms and to prevent or reduce craving of nicotine in said patient. Alternatively, an effective amount of bupropion base is delivered to alleviate depression in a patient. A transdermal delivery system includes a bupropion base. The bupropion base can be mixed with an acceptable pharmaceutical carrier.

Aerosol spray formulations capable of delivering high concentrations of active agent-containing materials and/or excipient are described herein. The formulation contains a carrier fluid, a propellant and a therapeutic, prophylactic, cosmeticeutical and/or inert solid suspended, dissolved, or dispersed in the formulation. The active ingredient may be an antibiotic, an antihistamine, an anesthetic, an anti-inflammatory, and/or an astringent. In one embodiment, the active agent is an antifungal agent. In another embodiment, the active agent is a cosmeticeutical. The active agent can optionally be dispersed on, or associated with, a carrier powder. The carrier fluid is a highly volatile silicone liquid, which evaporates in less than 10 minutes after application of the formulation to the patient's skin. The formulation may also contain one or more pharmaceutically acceptable excipients The formulation can be packaged in a conventional aerosol spray can.

Formulations are described for the treatment by enzymatic debridement of wounds and ulcers. The formulations have a clear, transparent composition that allows for easy visualization of the wound, and are non-staining for easy clean up. These formulations can also exhibit increased enzymatic debridement activity, improved post-treatment lubricity and coating occlusivity, and stability. The formulations, optionally containing non-animal source biologics, may be in the form of lotions, aerosols to provide a spray, or a foam. A non-reactive substrate may be used as a composition carrier. A non-aqueous lotion formulation having improved enzymatic activity is provided. The non-aqueous lotion viscosity is adjusted to achieve high enzymatic activity while maintaining the application benefits of high viscosity non-aqueous lotions. The lotion formulation may be delivered in a patch.

A stable topical aerosol foam is provided. The foam-forming formulation includes a HFA propellant and an active agent in an emulsion. The emulsion has an oil phase and an aqueous, i.e. water-containing, phase. The active agent may be present in either phase or dispersed in the emulsion. The oil phase may consist at least in part of the HFA propellant. Either or both of the oil phase and the aqueous phase may contain one or more surfactants, emulsifiers, emulsion stabilizers, buffers, and other excipients. In an alternative embodiment, the aqueous phase contains a water-soluble active agent, for example, a local anesthetic, and the oil phase contains a water-insoluble second active agent. The foam is stable on the skin, for example for at least 10 minutes at body temperature, and will disappear into the skin upon rubbing or after prolonged standing. The formulation has the advantage of an inert non-flammable hydrofluorocarbon propellant without requiring the use of additional co-solvents or co-propellants. The composition is administered to the skin or mucous membranes.
摘要:
Novel pharmaceutical dosage forms provide for pulsatile delivery of an antiarrhythmic agent that releases the drug in spaced apart “pulses.” The dosage forms are comprised of first, second and optional third dosage units, with each dosage unit having a different drug release profile. The dosage forms may comprise capsules housing compressed tablets or drug-containing beads, granules, or particles or may comprise a single tablet with the first, second and optional third dosage units incorporated therein, or a “coated core” dosage form. Methods of treatment using the pharmaceutical dosage forms are provided as well.
摘要:
A kit to alleviate tobacco-smoking withdrawal symptoms in a patient is disclosed which comprises: (a) a therapeutically effective amount of nicotine, at least one active nicotine metabolite, a combination of nicotine and an active nicotine metabolite, or an azapirone, or a pharmaceutically acceptable salt thereof; (b) a transdermal delivery system consisting essentially of a bupropion base in a therapeutically effective amount; and (c) a packaging material surrounding (a) and (b).

摘要:
Compositions containing both a sedative compound and a non-sedative antihistamine are provided. More particularly, compositions for administration at bedtime containing a sedating antihistamine or other sedating compound in immediate release form and a non-sedating antihistamine in delayed-release form are described. Alternatively, a composition, for administrating upon awakening, containing a non-sedating antihistamine in immediate release form, and a sedating antihistamine or other sedative in delayed-release form is described. Methods of inhibiting the release of histamines by administration of the compositions to a mammalian subject are also provided. The dosage forms may comprise other medications, such as leukotriene receptor antagonists, to enhance the suppression of histamine symptoms.
摘要:
Pharmaceutical compositions for transdermal administration containing a fatty acid salt, a dicarboxylic acid salt, an alkyl sulfonic acid salt, an aryl sulfonic acid salt, or an alkyl aryl sulfonic acid salt of an unstable active agent, such as bupropion free base or a derivative of burpropion free base, such as bupropion free base or derivative of bupropion free base, paroxetine, fluvoxamine, fluoxetine, sertraline, venlafaxine, duloxetine, and metabolites and derivatives thereof are described herein. The composition may also contain one or more antioxidants. The compositions can be prepared by forming the bupropion salt followed by addition of the antioxidant. Alternatively, bupropion can be combined first with the antioxidant followed by addition of the acid to form the salt. The compositions can be administered as a gel, cream, lotion, ointment, or patch and typically contain a pharmaceutically acceptable carrier and optionally one or more pharmaceutically acceptable excipients. The compositions described herein are expected to be more stable than bupropion free base and should exhibit excellent dermal penetration.
