Ontwerp van doseringsschema’s: nomogrammen en tabellen

Nomograms are essential tools for quickly and accurately determining patient dosage regimens.

A nomogram helps clinicians calculate initial dosages or adjust regimens based on various patient factors, such as age, gender, body weight, and physiological state.

The creation of a drug nomogram involves collecting and analyzing population pharmacokinetic data using specific models such as compartmental or physiological models.

Complex equations are solved to simplify dosage calculations, and the results are presented diagrammatically on scaled axes or in tables.

Some nomograms incorporate physiological parameters, such as serum creatinine concentration, to modify dosage according to renal function.

Pharmaceutical manufacturers often provide dosage guidelines for their products in tables or nomograms.

For drugs with a narrow therapeutic range, guidelines for monitoring serum drug concentrations are available.

For instance, tobramycin sulfate, an aminoglycoside antibiotic primarily eliminated through renal clearance, requires dosage reductions proportional to creatinine clearance reductions.
