Pseudovent Capsule Concentrations

Please provide the names and dosages of long acting capsules [12 to 24 hour type] with more Pseudophedrine than 60 mg [over the counter level] but less than the concentration of Pseudophedrine found in Pseudovent Capsules [120mg?]?

The Pseudovent Capsule prescription is too strong for me and I want to find a lower dosage capsule for my doctor to prescribe. He asked me to check with the drug store and they did not have the time to help me.

Thanks, Tom
