A "once a day administration" sustained-release theophylline formulation: disposition and pharmacokinetics.

The pharmacokinetics of a new sustained-release preparation of theophylline (Dilatrane à Action Prolongée capsules filled with homogenous microgranules) has been after its studied administration to 7 healthy volunteers at 8 p.m. in order to achieve therapeutic levels at night and in the morning. In separate trials the test dose of 500 or 600 mg was administered for 7 days, once daily at 8 p.m. Plasma theophylline levels were measured by capillary gas chromatography with a mass specific detector after pentylation, using internal standards labelled with stable isotopes (15N-1,3 and 13C-2 theophylline). The new sustained-release preparation showed a monophasic regular absorption phase with very low inter-individual variability. After administration, the plasma level stayed within 80% of the peak levels for 8.5 +/- 1.5 h. There was a good correlation between the dose and the steady state plasma level (r = 0.9587; p less than 0.05). This preparation can be chronically administered once daily day at 8 p.m. in order to achieve a therapeutic level during the night and the morning, and to provide sufficient protection during the nycterohemeral period, with a once dose a day schedule.

Factor VIII related antigen, coagulation tests and acute renal failure.

Coagulation factors were measured in 50 patients presenting with acute renal failure on the day of their admission (D1) and seven days later (D7). A number of changes were observed, particularly in those patients with a poor prognosis (decreased platelet counts and plasminogen concentrations and increased factor VIII related antigen concentrations). In the majority of cases it would appear that disseminated intravascular coagulation remains sub-clinical.
