The procedure is to take the child's weight in pounds, divide by 150 lb, and multiply the fractional result by the adult dose to find the equivalent child dosage.For example, if an adult dose of medication calls for 30 mg and the child weighs 30 lb, divide the weight by 150 (30/150) to obtain 1/5 and multiply 1/5 times 30 mg to get 6 mg.
Lipinski's rule of five, also known as Pfizer's rule of five or simply the rule of five (RO5), is a rule of thumb to evaluate druglikeness or determine if a chemical compound with a certain pharmacological or biological activity has chemical properties and physical properties that would likely make it an orally active drug in humans.
Oral drugs are normally taken as tablets or capsules. The drug (active substance) itself needs to be soluble in aqueous solution at a controlled rate.Such factors as particle size and crystal form can significantly affect dissolution.
An example for a simple case (mono-compartmental) would be to administer D=8 mg/kg to a human. A human has a blood volume of around V b l o o d = {\displaystyle V_{blood}=} 0.08 L/kg . [ 7 ] This gives a C 0 = {\displaystyle C_{0}=} 100 μg/mL if the drug stays in the blood stream only, and thus its volume of distribution is the same as V b l o ...
K is the clearance [mL/min] or [m 3 /s] C is the concentration [mmol/L] or [mol/m 3 ] (in the United States often [mg/mL]) From the above definitions it follows that d C d t {\displaystyle {\frac {dC}{dt}}} is the first derivative of concentration with respect to time, i.e. the change in concentration with time.
