Maximum Observed Plasma Concentration (Cmax) of Bisoprolol and Amlodipine
Time frame: Pre-dose (Baseline) and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 15, 24, 36, 48, 72, 96, 120, 144 and 168 hours post-dose for each treatment period
Time to Reach Maximum Plasma Concentration (Tmax) of Bisoprolol and Amlodipine
Time frame: Pre-dose (Baseline) and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 15, 24, 36, 48, 72, 96, 120, 144 and 168 hours post-dose for each treatment period
Apparent Terminal Half-life (t1/2) of Bisoprolol and Amlodipine
Apparent terminal half-life was defined as the time required for the plasma concentration of drug to decrease 50 percent in the final stage of its elimination. Terminal half-life was calculated as ln(2)/λz, where λz is a terminal rate constant, which was determined from the terminal slope of the log-transformed plasma concentration curve using linear regression on terminal data points of the curve.
Time frame: Pre-dose (Baseline) and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 15, 24, 36, 48, 72, 96, 120, 144 and 168 hours post-dose for each treatment period
Area Under the Plasma Concentration Time Curve From Time Zero to Infinity (AUC 0-inf) of Bisoprolol and Amlodipine
Time frame: Pre-dose (Baseline) and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 15, 24, 36, 48, 72, 96, 120, 144 and 168 hours post-dose for each treatment period
Extrapolated Part of Area Under the Plasma Concentration Curve From Time Zero to Infinity (AUCextra%) of Bisoprolol and Amlodipine
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
AUCextra% was calculated as area under the curve from time tlast extrapolated to infinity given as percentage of AUC 0-infinity. Here, tlast is the last sampling time at which the concentration is at or above the lower limit of quantification.
Time frame: Pre-dose (Baseline) and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 15, 24, 36, 48, 72, 96, 120, 144 and 168 hours post-dose for each treatment period
Apparent Terminal Elimination Rate Constant (λz) of Bisoprolol and Amlodipine
λz was determined from the terminal slope of the log-transformed plasma concentration curve using linear regression method.
Time frame: Pre-dose (Baseline) and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 15, 24, 36, 48, 72, 96, 120, 144 and 168 hours post-dose for each treatment period
Apparent Total Body Clearance From Plasma (CL/f) of Bisoprolol and Amlodipine
Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes.
Time frame: Pre-dose (Baseline) and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 15, 24, 36, 48, 72, 96, 120, 144 and 168 hours post-dose for each treatment period
Apparent Volume of Distribution During the Terminal Phase Following Extravascular Administration (Vz/f) of Bisoprolol and Amlodipine
Vz/f is defined as the distribution of a study drug between plasma and the rest of the body after oral dosing.
Time frame: Pre-dose (Baseline) and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 15, 24, 36, 48, 72, 96, 120, 144 and 168 hours post-dose for each treatment period
Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Serious TEAEs, AEs Leading to Death, and AEs Leading to Discontinuation
An Adverse event (AE) was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease associated with the use of study drug, whether or not considered related to the study drug or worsening of pre-existing medical condition, whether or not related to study drug. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. An AE was considered as 'treatment emergent' if it occurred after the first drug administration of each period or if it was present prior to drug administration but exacerbated after the drug administration. TEAEs included both Serious TEAEs and non-serious TEAEs.
Time frame: Baseline up to Day 29
