Nadolol was administered concomitantly with ephedrine to healthy volunteers. Nadolol completely inhibited changes in heart rate and plasma glucose due to it’s blockade of beta-1 and beta-2 receptors. However, the thermogenic effect of ephedrine was testicular dysfunction still at about 43%. This means that at least 40% of ephedrine’s testicular dysfunction thermogenic effects are due to beta-3 activation. This alone does not explain ephedrine’s effects after long term use. |

| advantages to using a non-specific beta agonist are two fold. First, although ephedrine binds questions to other adrenergic receptors, it seems that the most beneficial questions adrenergic effects, such as thermogenesis, are actually enhanced after chronic use.2,3 This may be explained by chronic stimulation of alpha receptors by NA and Adr. This chronic alpha-adrenergic stimulation may questions activate thyroxin deiodinases leading to the peripheral conversion of T4 to T3. In fact, significant increases in the ratio of T3 to T4 have been shown to occur after 4 weeks of chronic treatment of ephedrine.2 Increased levels of T3 can sensitize adrenergic sensitivity to NA and Adr. It should be noted that the same study showed that this ratio decreased below initial values after week 12 of treatment.Another explanation of its increased efficacy after chronic treatment is it’s interaction with the beta-3 receptor. |
