What is the difference between Fenbid and Keto

1. Structure and pharmacokinetic differences

Their structural differences are key to understanding their mechanisms of action. Fenbid contains an atypical beta-receptor binding site in its molecular structure, which makes it more efficient in inhibiting atrial beta 1 receptors. The structure of ketonidine is mainly dependent on the traditional beta receptor binding site, so it is more prominent in inhibiting ventricular beta receptors.

From the perspective of pharmacokinetics, ketoprazole is usually administered orally, metabolism is mainly carried out in the liver, and the absorption and metabolism rate is relatively stable. Because of its different molecular structure, Fenbid is usually used as an intravenous drug, and its metabolic pathway includes liver and kidney, and its metabolic rate is relatively faster.

Use Scenarios and Clinical Applications

In clinical application, the main uses of these two drugs are different. Fenbid is commonly used in antidepressant and antiepileptic treatment, in which it is more selective in antidepressant, especially has less effect on atrial receptors. The application of ketonidine in anti-epilepsy is more inclined to inhibit ventricular receptors, and the effect is more durable.

In the treatment of atrial fibrillation, fenbid is often recommend for the prevention of atrial fibrillation due to its greater selectivity for atrial receptors. Ketone is more often used as an adjunct to atrial fibrillation, especially as a long-term rate control drug.

Safety and Precautions

In terms of safety, ketohexidine may present a higher pharmacokinetic risk when administered acutely, such as lactic acidosis. Fenbid, because of its metabolic pathway, may in some cases lead to an increased risk of metabolic alkalosis.

In the process of use, both drugs should pay attention to dose adjustment, especially for patients with basic diseases such as liver and kidney insufficiency. ᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏᵏ Hyde fáciltky.
