The duration of individual pharmacotherapy is variable. The clinical studies on pentosan polysulfate sodium seem to suggest that maximal effects are not observed until the patient has been on drug therapy for 5-6 months. Other medications are dispensed and their effects are reevaluated as per the expected pharmacokinetics. For example, steady-state serum levels of many tricyclic antidepressants are not attained until 6-8 weeks of stable dosing. Only at this time can the drug dose be safely and reasonably adjusted.
