WebThe interaction of phenytoin and valproic acid was studied in four adults. We studied serial changes in total phenytoin concentrations, protein binding, urinary hydroxyphenylphenylhydantoin (HPPH) excretion, and half-life. In all four patients valproic acid caused an increase in the free fraction of phenytoin. WebIncreases levels/effect of dopamine, ticlopidine. Valproic acid may displace phenytoin from binding sites; and affect phenytoin serum concentrations. Transiently increases the hypothrombinaemia response to warfarin initially, followed by an inhibition of the response. WebFurosemide competes for T4-binding sites on TBG, prealbumin, and albumin, so that a single high dose can acutely lower the total T4 level. Phenytoin and carbamazepine reduce serum protein binding of levothyroxine, and total and free T4 may be reduced by 20% to 40%, but most patients have normal serum TSH levels and are clinically euthyroid. epikur software \u0026 it-service gmbh
