Sulfamethizole-induced inhibition of diphenlhydantoin, tolbutamide, and warfarin metabolism.

The influence of sulfamethizole on the metabolism of diphenylhydatoin (DPH) tolbutamide, and warefarian is examined. In 8 patients DPH means half-life (T/2) increased from 11.8 plus or minus 3.6 hr to 19.6 plus or minus 5.2 hr and mean metabolic clearance rate (MCR) decreased from 43.7 plus or minus 16,8 to 28.1 plus or minus 9.1 ml/min durus or minus 1.2 to 9.2 plus or minus 1.2 hr MCR decrease from 17.0 plus or minus 5.4 to 10.5 plus or minus 1.2 ml/min. In 2 patients warfarin T/2 increased fron an average of 64.7 to 92.7 hr and MCR decreased from 1.65 ml/min to 1.05 ml/min. In 4 patients on long-term DPH treatment after 1 wk on sulfamethizole inhibits hepatic metabolism of DPH, tolbutamide, and warfarin.

Age dependent changes in iodine metabolism and thyroid function.

Absolute iodine uptake (AIU), serum thyroxine (T4), free T4 index and serum triiodothyronine (T3) were studied in 48 women and 63 men aged 20 to 90 years. AIU decreased with age in both sexes to values in the oldest age groups of about 60% of the values in the youngest age groups. AIU values for females were about 75% of the values for males. Free T4 index was found to be unaltered with increasing age but serum T3 decreased with age. These findings and the previous demonstrated decrease in T4 degradation rate seem consistent with the assumption that T4 and T3 production decreases with advancing age.
