Compounded PDE-5 Inhibitor Compounded Formulations (Empower Pharmacy) by Dosage Form:
I. Buccal Troche
Definition: Troches are small lozenges that dissolve between the cheek and gum over a period of about 10-20 minutes. As the troche dissolves, the medication is gradually absorbed into the blood stream so that it can be absorbed more efficiently and in some cases more rapidly than if it was taken orally.
Anecdotal Benefits: Reported by some patients to have a faster onset than orally administered tablets.
Reported Negative: Some medications can leave a bitter aftertaste despite flavoring. Sometimes the troche does not completely dissolve and needs to be swallowed.
Route of Administration: Buccal administration refers to a topical route of administration by which drugs held or applied in the buccal area (in the cheek) diffuse through the oral mucosa (tissues which line the mouth) and enter directly into the bloodstream. If the troche is swallowed prior to dissolving, it will still absorb PO.
Storage: To prevent melting, troches should be stored at 70 degrees or lower. We suggest storing them in the refrigerator in warmer climates.
1. Sildenafil
Dosage form: Buccal troche
Available strength: 100 mg
Commercial version: Viagra; Revatio
Dose: Dissolve ½-1 troche between the gum and cheek (buccally) 60 min prior to sexual activity. Troches are small lozenges that dissolve between the cheek and gum over a period of about 10-20 minutes. As it dissolves, the medication is gradually absorbed into the bloodstream so that it can be absorbed more efficiently and in some cases faster than if the same medication was taken orally.
2. Tadalafil
Dosage form: Buccal troche
Available strength: 25 mg
Commercial version: Cialis
Dose: Dissolve one troche between the gum and cheek (buccally) 60 min prior to sexual activity. Do not take more than 25 mg every 36 hours. Tadalafil troches are scored and can be broken into smaller doses, this allows for a cost-effective method of administering smaller daily dosages.
3. Avanafil
Dosage form: Buccal troche
Available strength: 200 mg
Commercial version: Stendra
Dose: Dissolve one troche between the gum and cheek (buccally) 15-30 min prior to sexual activity.

The lowest dose that provides benefit should be used. The maximum recommended dosing frequency is once per day.

II. Capsules
Definition: Capsules have been used for administering medications to patients for more than a century and have an important role in drug delivery. When a primary care provider prescribes a tablet, the choice is usually, but not always, limited to commercially available products. A capsule, however, can be prepared extemporaneously, which provides dosing flexibility for the primary care provider and the pharmacist. Compounded capsules are usually gelatin based.
Benefits: Free of excipients and dyes. Can be made without fillers. Capable of sustained release, which alters the pharmacokinetics of the medication by slowing metabolism to lengthen duration of action.
Reported Negative: Cannot be broken into smaller dosages. The entire capsule must be administered at once.
Route of Administration: Taken by mouth (PO).
Storage: Room temperature.

Anecdotal Benefits: Faster onset of medication has been reported. Increased compliance in patients who have difficulty swallowing tablets. Can be taken without water.
Reported Negative: Some medications can leave a bitter aftertaste despite flavoring.
Route of Administration: Sublingual administration is when medication is placed under the tongue to be absorbed by the body. The word “sublingual” means “under the tongue.” Buccal administration involves placement of the drug between the gums and the cheek.
