Pediatric doctors need to calculate the doses of every drug carefully. It is labor-intensive parts of pediatric medicine. It is tough enough remember all those drugs doses. Incorrect dosing in frequency and amount could result in harm rather than helping. Pediatric dose calculator app can be very useful in saving time. But you must have the basic idea behind the calculations done by the apps.
- Birth to 1 year of age has greater percentage of body water
- Age 1 to 12 years metabolizes drugs more readily than adults
There may be an overdose, toxic reactions, and even death for incorrect medication dosing. Because the children’s have immature physiological processes such as absorption, distribution, metabolism, excretion.
Remember-There is no standard dose. Safe Pediatric doses are calculated by Body weight and Body surface area. So knowing the weight is extremely important. The usual unit for weight is Kg. There is also Unit named by “Pound”. So the knowing the interrelation is quite necessary.
1 kg = 2.2 lb (Pound)
The doses can be written in several ways. It may be In a daily total to be divided into equal doses as for example 50mg/kg/day equally divided in three doses or Per dose like 30mg/kg TID.
All pediatric dosages have a recommended range in the drug guide. Like for Ceftriaxone it is 50-100mg/kg/day. These ranges are typically based on a 24-hour total amount of a dosage in mg, mcg, gm etc.
How to Calculate the Liquid or Syrup?
Desired Dose X quantity in ml divided by Dose on hand = volume to be administered
As for example, syrup contains 250/5ml. The order is 75mg. So the volume to be administered is 75*5/250= 1.5 ml.
Amoxicillin Dose for Children:
Amoxicillin is a penicillin group of drug good against streptococcal pharyngitis, pneumonia, and other Gram-Positive positive bacteria. Pediatric dose is 20-50mg/kg/day per oral divided into 3 doses. 50-100mg/kg/day in 3 divided doses for IM, IV Injections.
Available preparations are 250mg, 500mg cap, 125mg/5ml syrup and DS 250mg/5ml, 125mg/1.25ml oral drop, 250, 500mg IV/IM vial. A 10 Kg child will need 20*50=1000mg per day. Which if we divide into 3 doses, the rate is 333 mg per dose. So the dose will be 333*5/250=6.6 ml per dose.
This complex calculation can be solved by these pediatric dose calculator app. Note, this is only for Doctors and health care providers. I will not bear any responsibilities for misuse of any app or will not take any reponsibilities for the misuse of the information provided here.
