Arguments

• t: Time after dose (h)
• dose: Dose
• dur: Duration of zero-order absorption (h)
• tinf: Duration of infusion (h)
• ...: Passed to calc_derived_1cpt()

Returns

Concentration of drug at requested time (t) after a single dose, given provided set of parameters and variables.

Functions

• calc_sd_1cmt_linear_bolus(): Calculate C(t) for a 1-compartment linear model after a single IV bolus dose
• calc_sd_1cmt_linear_oral_1_lag(): Calculate C(t) for a 1-compartment linear model with first-order absorption after a single oral dose, with lag time
• calc_sd_1cmt_linear_infusion(): Calculate C(t) for a 1-compartment linear model after a single IV infusion
• calc_sd_1cmt_linear_oral_0(): Calculate C(t) for a 1-compartment linear model with zero-order absorption after a single oral dose
• calc_sd_1cmt_linear_oral_1(): Calculate C(t) for a 1-compartment linear model with first-order absorption after a single oral dose
• calc_sd_1cmt_linear_oral_0_lag(): Calculate C(t) for a 1-compartment linear model with zero-order absorption after a single oral dose, with lag time

Examples
