Description

Pediatrics is the medical specialty that deals with the treatment of new borns, children, and adolescents. A new-born’s physiological composition differs from that of an adult. Pediatricians are more concerned than adult physicians with congenital abnormalities, genetic variance, and developmental issues. Children are not just small grownups, according to a popular truism. The doctor must remember the infant or child developing physiology when analyzing symptoms, administering medications, and diagnosing illnesses.

The physiology of children has a direct impact on the pharmacokinetics effects of drugs that enter the body. Medications are absorbed, distributed, metabolised, and eliminated differently in developing children and adults. Despite of the result completed studies and reviews, more research is needed to better understand how these criteria should impact healthcare practitioners decisions when prescription and administering drugs to children.

Neonates and new born babies have a higher stomach pH due to their reduced acid output, which creates a more basic environment for drugs taken by mouth.

Several oral medicines require acid to be decomposed before they can be absorbed into the body. Children absorb more of these drugs than adults because of the slower breakdown and increased preservation in a less acidic stomach region. Similarly, children's stomachs empty at a slower rate, which decreases drug absorption. Drug absorption is boosted by enzymes that came in contact with the drug for the treatment as it goes through the body. The quantity of these enzymes rises as children's gastrointestinal tracts mature. Because children's proteins are still developing, their metabolism is slower and chemical levels in their blood are higher. Pro drugs, on the other hand, have the opposite effect because enzymes are required for their active form to enter systemic circulation.

The percentage of total body water and extracellular fluid volume both decrease as children grow and develop. Paediatric patients have a larger distribution volume than adults, which affects how hydrophilic medicines like beta-lactam antibiotics like ampicillin are dosed. To account for this important change in body composition, many medications are given at higher weight-based doses or with altered dosing intervals in youngsters. Infants and neonates have fewer plasma proteins. As a result, highly protein-bound medications have fewer opportunities to connect to proteins, leading to increased dispersion.

Drug metabolism is primarily mediated by enzymes in the liver, and it might differ depending on which enzymes are impacted at a given stage of development. Depending on their individual method of action, such as oxidation, hydrolysis, acetylation, or methylation, Phase I and Phase II enzymes mature and evolve at distinct speeds. Factors including enzyme capacity, clearance, and half-life determine differences in metabolism between children and adults. Even within the paediatric population, drug metabolism might change, differentiating neonates, infants, and young children.

Drug elimination is mostly dependent on the liver and kidneys. The bigger relative size of the kidneys in new born and young children leads to increased renal clearance of drugs that are removed by urine. Because preterm neonates and infants kidneys mature more slowly than fully matured kidneys, they are unable to pass as much medication. Lower doses and longer dosing intervals should be explored for this population because this can lead to unwanted drug build-up. Diseases that affect kidney function might have a comparable impact and requiring similar treatment.
