What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TILACEMDrug
At 08:00 hours on day 1, CIF-BIOTEC personnel will start to administer the study drug. Each volunteer will receive a single dose of 60 mg of Diltiazem. The study drugs will be ingested with 250 mL of drinking water. Research Pharmacy personnel will inspect the volunteer's oropharynx to ensure that he/she has swallowed the tablet and record their observations in the corresponding forms.
ANGIOTROFINDrug
At 08:00 hours on day 1, CIF-BIOTEC Pharmacy personnel will start to administer the study drug. Each volunteer will receive a single dose of 60 mg of Diltiazem. The study drugs will be ingested with 250 mL of drinking water. Research Pharmacy personnel will inspect the volunteer's oropharynx to ensure that he/she has swallowed the tablet and record their observations in the corresponding forms.

What is being measured
The primary outcome is the main question the study is designed to answer.
Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-t)]
AUC (0-t)= Area under the plasma concentration versus time curve from time zero (pre-dose) to time of last quantifiable concentration (0-t)
Measured: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12, 24 hours post dose
Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0-∞)]
AUC (0-∞) = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-∞). It is obtained from AUC (0-t) plus AUC (t-∞).
Measured: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12, 24 hours post dose
Maximum Observed Plasma Concentration (Cmax)
Measured: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12, 24 hours post dose
Time to Reach Maximum Observed Plasma Concentration (Tmax)
Measured: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12, 24 hours post dose
Plasma Decay Half-Life (t1/2)
Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.
Measured: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12, 24 hours post dose

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing TILACEM and ANGIOTROFIN in people with Healthy, run by Pfizer at 1 site in Mexico.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Sep 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Mexico. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 22 Aug 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-t)] (time frame: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12, 24 hours post dose). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Sep 2011.
