Testing Potential Synergistic Effects of Albuterol and Caffeine on Metabolic Rate.
Study Overview
Status
Conditions
Detailed Description
The study consists of 2 screening visits and 8 study visits. Screening visit 1: about 1 hour fasting from 9pm the prior night. Height and weight is measured, vital signs taken and questionnaires completed. Women will have a urine pregnancy test. Blood draw for chemistry panel and blood count.
Screening visit 2: about 1 hour, Medical history, physical examination, and electrocardiogram (a heart tracing).
Visit 1-8 about 4 hours each. 8 separate occasions, with about 7 days between each visit. ON each visit, blood pressure, pulse and temperature is recorded. A resting metabolic rate (RMR) is measured. After a baseline measurement of about 30 minutes of breathing is taken , a pill will be swallow and metabolism(measured by breathing with a clear plastic hood over the upper body to measure metabolic rate ( the oxygen inhaled and the carbon dioxide exhaled).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
A change is being assessed for the combination of Albuterol and Caffeine on Metabolic rate.
Time Frame: Participants will be followed at Baseline and the duration of the study, an expected average of 10 weeks.
|
The order of which 8 combinations will be determined randomly (like flipping a coin) and neither the participant nor the study personnel will know what is in the pills.
The identity of the pills can be determined by breaking the code in the case of an emergency.
1. Albuterol 2mg; 2. Albuterol 4mg; 3. Caffeine 100mg; 4. Caffeine 200mg; 5. Albuterol 2mg and Caffeine 100mg; 6. Albuterol 2mg and Caffeine 200mg; 7. Albuterol 4mg and Caffeine 100mg; 8. Albuterol 4mg and Caffeine 200mg.
The data will be analyzed by computing the metabolic rate.
Metabolic rate is measured by breathing with a clear plastic hood over the upper body to measure the oxygen inhaled and the carbon dioxide exhaled.
|
Participants will be followed at Baseline and the duration of the study, an expected average of 10 weeks.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Respiratory Quotient (RQ)
Time Frame: Participants will be followed at Baseline and the duration of the study, an expected average of 10 weeks.
|
The respiratory quotient (RQ) is calculated from a ratio indicating the relation of the volume of carbon dioxide given off in respiration to that of the oxygen consumed.
|
Participants will be followed at Baseline and the duration of the study, an expected average of 10 weeks.
|
Pulse rate
Time Frame: Participants will be followed at Baseline and the duration of the study, an expected average of 10 weeks.
|
Pulse is the rate at which the heart beats.
The pulse is usually called heart rate, which is the number of times the heart beats each minute.
|
Participants will be followed at Baseline and the duration of the study, an expected average of 10 weeks.
|
Blood Pressure
Time Frame: Baseline to 8 time points of dose
|
When the heart beats, it contracts and pushes blood through the arteries to the rest of your body.
This force creates pressure on the arteries.
This is called systolic blood pressure or the top number.
A systolic blood pressure or the bottom number indicates the pressure in the arteries when the heart rests between beats.
|
Baseline to 8 time points of dose
|
Temperature
Time Frame: Participants will be followed at Baseline and the duration of the study, an expected average of 10 weeks.
|
An oral temperature is when the thermometer is placed in the mouth to measure the body heat.
|
Participants will be followed at Baseline and the duration of the study, an expected average of 10 weeks.
|
Safety Assessments (lab, adverse events, physical exams and electrocardiograms)
Time Frame: Participants will be followed at Baseline and the duration of the study, an expected average of 10 weeks.
|
Labs, adverse events, physical exams and electrocardiograms (ECG or EKG) are assessed to make sure nothing is out of normal range.
|
Participants will be followed at Baseline and the duration of the study, an expected average of 10 weeks.
