Changes in blood chemistry in hypertensive patients during propranolol therapy.

Abstract:

:Propranolol induced changes in blood plasma chemistry were followed in thirty hypertensive patients (WHO I-II) who were seen each week during 14-15 weeks. The initial 4 weeks were a drug free period and the next 2 weeks were a drug adjustment period. After that the patients were on an unchanged propranolol dose for 8 weeks (40, 80 or 160 mg four times daily). For all observed changes the correlation was studied to (1) dose, (2) free and total simultaneously determined plasma concentration and (3) free and total average plasma concentration of unchanged drug during the preceding 24 h period. Total protein and albumin did not change significantly. After 4 and 8 weeks on the final dose orosomucoid was increased significantly (by 10%) compared with the value from the end of the drug free period. Creatinine rose significantly during the initial 4-6 weeks therapy to remain at the same level during the last 4 weeks. Urate was increased at the two lowest dose levels. Total cholesterol fell significantly (5%) while triglycerides increased significantly (16%). T4 rose significantly, T3 fell and r-T3 rose significantly in a dose dependent way. Interindividually r-T3 was the only biochemical change showing a significant relationship to the propranolol plasma concentration. The relationship reached the highest level of significance to the average 24 h free concentration.
