摘要:
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.
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).

The invention includes a patch and method for transdermal delivery of bupropion base. In the method of this invention, a patient is administered 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 or to treat obesity. A transdermal patch includes a bupropion base. The bupropion base can be mixed with an acceptable pharmaceutical carrier.
摘要:
New pharmaceutical compositions in unit dosage form are disclosed for both intraoral and oral administration to a patient, said unit dosage form configured to be placed intraorally of said patient, which comprises: (a) as a first portion, at least one discrete molded triturate tablet comprising a therapeutically effective amount of at least one pharmaceutically active ingredient capable of intraoral administration; and (b) as a second portion located around the said first portion, a therapeutically effective amount of at least one pharmaceutically active ingredient capable of oral administration and which is releasable and orally ingestible by the patient after the molded triturate tablet has disintegrated or has dissolved intraorally.
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.
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.
摘要:
A composition for anesthetizing oral or buccal tissues, especially periodontal pockets, is provided. The composition has a high concentration of topical anesthetic carried in a non-aqueous liquid vehicle containing a gelling agent. The anesthetics are optionally stabilized in the solution by ion-exchange complexation. The composition can anesthetize the gingivae for an extended period, such as 30 minutes or longer. Preferred anesthetics include tetracaine, benzocaine, butamben, and mixtures of these.
