About this trial

The purpose of this study is to compare over the counter and alternative prescription urinary alkalinizing agents to slow release potassium citrate in their ability to modify urinary parameters associated with stone formation.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Adults aged 18 and older.

with or without a history of stone disease.

Disqualifiers

They are unable to take any of the medications due to health reasons.

Participants are pregnant or nursing.

Participants are unable to adhere to the metabolic diet.

Participants had a prior adverse event from one or more of the medications.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Potassium citrate

    Drug

    Slow release potassium citrate UroCit-K. Participants will take 20mEq twice daily.

  • Sodium bicarbonate

    Drug

    650mg tabs. Take 3 tabs twice daily.

  • Litholyte

    Dietary supplement

    One packet is taken with 170ml of water. Two packets daily.

  • Crystal Lite

    Dietary supplement

    The classic lemonade contains 21.7mEq/liter of alkali Therefore, patients will take 2 litres daily to have the 40mEq of alkali daily needed.

  • Potassium Bicarbonate

    Drug

    20 mEq tablets, one tablet twice daily

Secondary outcomes

1

# of patient who adherence to 100% Medication

Patient's adherence to medication for duration of study.

Time frame
At the end of study approximately 10 weeks after start of study.
2

Total out of pocket cost

Calculate and compare treatment costs for the different interventions (in American dollars).

Time frame
At the end of study approximately 10 weeks after start of study.
3

Patient's Satisfaction Survey

Patient satisfaction survey, adapted from the Treatment Satisfaction Questionnaire for Medication-14. Patients are queried on their satisfaction, with 9 questions for each medication.

Time frame
At the end of study approximately 10 weeks after start of study.
4

Patient's GI Distress

Patient's GI distress symptom scale measures patients GI distress. There are 18 questions with descriptive answers ranging from "none", "mild", "moderate", "quite a lot" and "unbearable". There are no numerical scores, rather just descriptive scores. "None" means no GI distress, "unbearable" means that you are in a lot of distress from your GI symptoms.

Time frame
At the end of study approximately 10 weeks after start of study.
