Abstract: The invention pertains to a method for preparing diphenhydramine tannate by reacting diphenhydramine free base at a temperature of about 75 to about 150° C. with tannic acid neat or as an aqueous slurry containing up to about 20 wt. % water. The diphenhydramine free base may be obtained by reacting a commercially available diphenhydramine salt such as diphenhydramine maleate with a base such as aqueous sodium hydroxide. The resultant diphenhydramine tannate has extended release properties and is useful in pharmaceutical compositions as an antihistamine for human beings.

Abstract: The invention pertains to a method for preparing dexchlorpheniramine (“dexchlor”) tannate by reacting dexchlorpheniramine free base at a temperature of about 75 to about 150° C. with tannic acid neat or as an aqueous slurry containing up to about 20 wt. % water. The dexchlorpheniramine free base may be obtained by reacting a commercially available dexchlorpheniramine salt such as dexchlorpheniramine maleate with a base such as aqueous sodium hydroxide. The resultant dexchlor tannate has extended release properties and is useful in pharmaceutical compositions as an antihistamine for human beings.

Abstract: Intranasal delivery methods and compositions for the delivery of dopamine receptor agonists are provided which are effective for the amelioration of erectile dysfunction in a mammal without causing substantial intolerable adverse side effects to the mammal. Nasally administered compositions for treating male erectile dysfunction in a mammal are also provided which include a therapeutically effective amount of a dopamine receptor agonist which has been dispersed in a system to improve its solubility and/or stability.

Abstract: The invention pertains to a method for preparing diphenhydramine tannate by reacting diphenhydramine free base at a temperature of about 75 to about 150° C. with tannic acid neat or as an aqueous slurry containing up to about 20 wt. % water. The diphenhydramine free base may be obtained by reacting a commercially available diphenhydranine salt such as diphenhydramine maleate with a base such as aqueous sodium hydroxide. The resultant diphenhydramine tannate has extended release properties and is useful in pharmaceutical compositions as an antihistamine for human beings.

Abstract: Intranasal delivery compositions and methods for the delivery of dopamine receptor agonists are provided which are effective for the treatment14 of sexual dysfunction in a mammal without causing substantial intolerable adverse side effects to the mammal, in particular adverse nasal effects. Nasally administered compositions for treating sexual dysfunction in a mammal are also provided which include a therapeutically effective amount of a dopamine receptor agonist which has been dispersed in a system to improve its solubility and/or stability.

Abstract: The present invention relates to a pharmaceutical formulation for intranasal administration comprising morphine or pharmaceutically acceptable salt thereof at a pH from about 3.0 to about 7.0. Such formulations provide enhanced absorption of morphine or pharmaceutically acceptable salts thereof. In one embodiment, the present invention provides a method for eliciting an analgesic or anesthetic response in a mammal which includes nasally administering a therapeutically effective amount of morphine or pharmaceutically acceptable salt thereof at a pH from about 3.0 to about 7.0.

Abstract: The invention pertains to a novel composition comprising dextrochlorpheniramine tannate and to a method for preparing such tannate by reacting dextrochlorpheniramine free base at a temperature of about 60 to about 150° C. with tannic acid preferably neat or as an aqueous slurry containing about 5 to about 30 wt. % water. The dextrochlorpheniramine tannate has extended release properties and is useful in pharmaceutical compositions as an antihistamine for human beings.
