[0131] The term "plasticizer" as used herein includes any compounds capable of plasticizing or softening a polymer or a binder used in the paper help parts 5510114 present invention. A summary of the breakdown of each trial per part was described in Table 46. wherein said composition provides controlled release of said bupropion hydrobromide. Thus, the spraying air pressure can be increased in order to promote the formation of a homogeneous film of lipid matrix agent around the grains. 1oC and a smaller sharp peak at 205oC. [0190] In certain embodiments, the XL control-releasing coat further comprises a plasticizer. When the release rates of the tablets with the 30mg and the 28mg weight gains were compared, there was only a slight difference noticed in the release. 2 for paper help parts 5510114 2 hours, Acetate Buffer pH 4. [0117] "Controlled release dosage forms" or "control-releasing dosage forms", or dosage forms which exhibit a "controlled release" of the bupropion salt as used herein is defined to mean dosage forms administered once-or twice-daily that release the bupropion salt at a controlled rate and provide plasma concentrations of the bupropion salt that remain controlled with time within the therapeutic range of the bupropion salt over a 12 or 24-hour period. [0173] The granules can also be manufactured by using other processes known to the skilled artisan. In certain embodiments the paper help parts 5510114 moisture barrier coat comprises a plasticizer. [0545] In at least one embodiment, the core of the osmotic dosage form comprises bupropion hydrobromide. Keeping these inherent difficulties in mind, and using HLB values as a guide, one skilled in the art can readily identify surfactants having suitable hydrophilicity or lipophilicity for paper help parts 5510114 use in the present invention, as described herein. It is believed that bupropion works by inhibiting the reuptake of the neurotransmitters dopamine, serotonin, and norepinephrine, an action which results in more dopamine, serotonin, and norepinephrine made available to transmit messages to other nerves. A wide variety of low molecular weight and low viscosity hydrophilic polymers can be used in the osmotic subcoat. [0192] Preparation and application of the paper help parts 5510114 XL control-releasing coat can be as follows. an atomizing pressure of from 0. Typically the paper help parts 5510114 medicaments of the present invention are orally administrable. In embodiments where the mode of exit of the bupropion salt comprises a plurality of pores, the amount of pore forming agent employed to achieve the desired in-vitro dissolution rates can be readily determined by those skilled in the drug delivery art. [033] According to another aspect of the invention, there is provided a use of bupropion hydrobromide to prepare a medicament to treat conditions which benefit from administration of bupropion, wherein said medicament has greater stability than a corresponding medicament comprising bupropion hydrochloride. In all instances wherein prophetic examples are provided these compositions are intended to be exemplary and it should be understood that the paper help parts 5510114 specific procedures, constituents, amounts thereof and the like may be varied in order to obtain a composition possessing desired properties. 4,002,173, the anionic hydrogels of heterocyclic N-vinyl monomers as disclosed in U.
