Arms and Interventions

Arm

Intervention/treatment

Experimental: diltiazem

Drug: TILACEM; 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.; Drug: ANGIOTROFIN; 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.

Outcome Measures

Primary Outcome Measures :

1. 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 ]
   AUC (0-t)= Area under the plasma concentration versus time curve from time zero (pre-dose) to time of last quantifiable concentration (0-t)
2. Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0-∞)] [ 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 ]
   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-∞).
3. Maximum Observed Plasma Concentration (Cmax) [ 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 ]
4. Time to Reach Maximum Observed Plasma Concentration (Tmax) [ 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 ]
5. Plasma Decay Half-Life (t1/2) [ 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 ]
   Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.
