Tolmetin and G-6-PD erythrocyte deficiency: research in vitro.

In thirty-two patients, divided into four groups: normal, G-6-PD deficient, beta-thalaxemic heterozygote and carriers of both anomalies, the variations in erythrocyte GSH were studied after incubation with APH and a non-steroidal anti-inflammatory drug: tolmetin sodium. The results obtained show a considerable fall in GSH after incubation with APH above all in the G-6-PD deficient patients and in the carriers of both anomalies. On the other hand, after incubation with the drug under examination there were no significant variations in the erythrocyte GSH.
