Such as, acidic urine in sufferers with urinary tract bacterial infections can boost the excretion of weakly acidic drugs like penicillin.
– Genetics: Genetic variations in drug-metabolizing enzymes, transporters, and drug targets can affect person responses to medications. Pharmacogenomic tests will help forecast drug efficacy and toxicity based on an individual’s genetic makeup.

Since it is difficult to grasp everything and Health care is often evolving, they are the moments when enhanced dosing information and facts gets to be crucial.
