Safety of psuedoephedrine drug products

A drug product comprising:

• a drug substance consisting of an organic acid addition salt of an active pharmaceutical wherein said active pharmaceutical is selected from the group consisting of pseudoephedrine and ephedrine and said organic acid addition salt is defined by Structure A
• wherein R1-R4 are independently selected from H, alkyl of 1-6 carbons, adjacent groups may be taken together to form a cyclic alkyl, cyclic alkyl-aryl, or cyclic aryl moiety;
• R5 is selected from H, or an alkali earth cation;
• R6 and R7 are independently selected from H, alkyl of 1-6 carbons, an alkali earth cation, and aryl of 6 to 12 carbons, in a number sufficient to complete the valence bonding of X, and
• wherein X is selected from nitrogen, oxygen or sulfur;
• and
• an additive selected from the group consisting of alditol acetal and an organic acid defined by Structure H:
• wherein R8-R11 are independently selected from H, alkyl or substituted alkyl of 1-6 carbons, adjacent groups may be taken together to form a cyclic alkyl, cyclic alkyl-aryl, or cyclic aryl moiety;
• R12 is selected from H, or an alkali earth cation;
• R13 and R14 are independently selected from H, alkyl of 1-6 carbons, an alkali earth cation, and aryl of 6 to 12 carbons, in a number sufficient to complete the valence bonding of X1;
• and
• wherein X1 is selected from nitrogen, oxygen or sulfur;
• and
• wherein said drug product is in a dose form selected from solid and liquid.
