  • Steady State Area Under the Plasma Concentration Versus Time Curve From 0 to 12 Hours After Dosing (AUC0-12) of Oseltamivir and Oseltamivir Carboxylate [ Time Frame: Pre-dose; 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, and 12 hours post-dose on Day 5 ] [ Designated as safety issue: No ]
    Oseltamivir carboxylate is active metabolite of oseltamivir. AUC0-12 of oseltamivir and oseltamivir carboxylate were calculated following the administration of oseltamivir alone or in combination with rimantadine, using the linear trapezoidal rule.
  • Steady State Area Under the Plasma Concentration Versus Time Curve From 0 to 12 Hours After Dosing (AUC0-12) of Rimantadine [ Time Frame: Pre-dose; 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, and 12 hours post-dose on Day 5 ] [ Designated as safety issue: No ]
    AUC0-12 of rimantadine was calculated following the administration of rimantadine alone or in combination with oseltamivir, using the linear trapezoidal rule.
  • Effect of rimantadine on the pharmacokinetics of oseltamivir: AUC, Cmax [ Time Frame: Day 5 (pre-dose and during 12 hours post-dose) ] [ Designated as safety issue: No ]
  • Effect of oseltamivir on the pharmacokinetics of rimantadine: AUC, Cmax [ Time Frame: Day 5 (pre-dose and during 12 hours post-dose) ] [ Designated as safety issue: No ]

  • Maximum Plasma Concentration (Cmax) of Oseltamivir and Oseltamivir Carboxylate [ Time Frame: Pre-dose; 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, and 12 hours post-dose on Day 5 ] [ Designated as safety issue: No ]
    Oseltamivir carboxylate is active metabolite of oseltamivir. Cmax of oseltamivir and oseltamivir carboxylate were calculated following the administration of oseltamivir alone or in combination with rimantadine and was directly observed from the data.
  • Maximum Plasma Concentration (Cmax) of Rimantadine [ Time Frame: Pre-dose; 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, and 12 hours post-dose on Day 5 ] [ Designated as safety issue: No ]
    Cmax of rimantadine was calculated following the administration of rimantadine alone or in combination with oseltamivir and was directly observed from the data.
  • Number of Participants With Any Adverse Events (AEs) and Any Serious Adverse Events (SAEs) [ Time Frame: Up to 11 weeks ] [ Designated as safety issue: No ]
    An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered to be related to the medicinal product. An SAE is any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or results in a congenital anomaly/birth defect.
  • Number of Participants With Abnormal Vital Signs [ Time Frame: Screening (Days -28 to -2); pre-dose and 2h post-dose on D1 and D5 of each treatment period; at Follow-up visit (10 -14 days after last dose) for blood pressure and HR; Screening; Day -1 of each treatment period; Follow-up visit for temperature ] [ Designated as safety issue: No ]
    Vital signs included heart rate (HR), blood pressure (systolic blood pressure [SBP] and diastolic blood pressure [DBP]), and body temperature. Blood pressure and pulse rate were recorded when participants were rested in a supine position for at least 5 minutes and after standing for 2 minutes. Vital signs values that fall outside the investigator's normal ranges were recorded.
  • Number of Participants With Marked Abnormality in Laboratory Parameters [ Time Frame: Screening; Day -1 and Day 5 (pre-dose) of each treatment period; Follow-up visit ] [ Designated as safety issue: No ]

    Laboratory analysis included hematology (hemoglobin, hematocrit, erythrocytes, platelets counts, leukocytes counts, neutrophils, eosinophils, lymphocytes, basophils, and monocytes);, biochemistry (aspartate aminotransferase , alanine aminotransferase, gamma glutamyl trans peptidase, total bilirubin, alkaline phosphatase, lactate dehydrogenase, albumin, creatinine, urea, creatine phosphokinase, total protein, sodium, chloride, calcium, phosphate, potassium, glucose (fasting), amylase, lipase, total cholesterol, and calculated creatinine clearance); and urinalysis.

    Marked laboratory test values (high and low) falling outside the marked reference range and which also represents a clinically relevant change from baseline of at least a designated amount were recoded. In this study, marked abnormality ranges for phosphate as 0.75 - 1.60 millimole (mmol)/L and proteinuria (0 to 4+, and 1).

  • Number of Participants With Clinically Significant or Treatment Related Changes in Electrocardiogram (ECG) [ Time Frame: Screening; pre-dose on Day 1 and Day 5 of each treatment period; Follow-up visit ] [ Designated as safety issue: No ]
    ECG was recorded when participants were rested in a supine position for at least 5 minutes.
Safety and tolerability: Adverse events, laboratory parameters, vital signs, ECG [ Time Frame: up to 7 weeks ] [ Designated as safety issue: No ]

A Pharmacokinetic Study on Co-administration of Tamiflu (Oseltamivir) and Rimantadine in Healthy Volunteers
An Open-label, Multiple Dose, Randomized, Three-period Crossover Study in Healthy Subjects to Evaluate the Effect of Co-administration of Oseltamivir (Ro 64-0796) 75 mg Twice Daily and Rimantadine 100 mg Twice Daily on the Pharmacokinetic Properties of Oseltamivir and Rimantadine.
This open label, randomized, three-period crossover study will evaluate the effect of co-administration of Tamiflu (oseltamivir) and rimantadine on the pharmacokinetics of Tamiflu and rimantadine. Healthy volunteers will receive multiple oral doses of Tamiflu, rimantadine or Tamiflu plus rimantadine in random order, with a minimum wash-out period of 7 days between treatments. Anticipated time on study is up to 11 weeks.
