A possible interaction between d-1 propranolol and hyperparathyroid plasma ultrafiltrate on guinea pig auricles has been studied in "in vitro" experiments. Plasma ultrafiltrates have been samples in two patients on chronci haemodialysis before (pre-PTx) and after (post-PTx) parathyroidectomy. A significant inhibition of propranolol depressant activity on cardiac contractile strength has been observed in the presence of pre-PTx plasma ultrafiltrates. On the contrary, no such inhibition was noted in the presence of post-PTx plasma ultrafiltrates.
