Propafenone

1-(2-(2-Hydroxy-3-(propylamino)propoxy)phenyl)-3-phenyl-1-propanone

C21H27NO3 (341.1991)


Propafenone is only found in individuals that have used or taken this drug. It is an antiarrhythmia agent that is particularly effective in ventricular arrhythmias. It also has weak beta-blocking activity. The drug is generally well tolerated. [PubChem]The electrophysiological effect of propafenone manifests itself in a reduction of upstroke velocity (Phase 0) of the monophasic action potential. In Purkinje fibers, and to a lesser extent myocardial fibers, propafenone reduces the fast inward current carried by sodium ions, which is responsible for the drugs antiarrhythmic actions. Diastolic excitability threshold is increased and effective refractory period prolonged. Propafenone reduces spontaneous automaticity and depresses triggered activity. At very high concentrations in vitro, propafenone can inhibit the slow inward current carried by calcium but this calcium antagonist effect probably does not contribute to antiarrhythmic efficacy.

Propafenone also has high affinity for the β receptor (IC50=32 nM)[1]. Propafenone blocks the transient outward current (Ito) and the sustained delayed rectifier K current (Isus) with IC50 values of 4.9?μm and 8.6?μm, respectively[2]. Propafenone suppresses esophageal cancer proliferation through inducing mitochondrial dysfunction and induce apoptosis[3].

   

Amiodarone

{2-[4-(2-butyl-1-benzofuran-3-carbonyl)-2,6-diiodophenoxy]ethyl}diethylamine

C25H29I2NO3 (645.0237)


Amiodarone is only found in individuals that have used or taken this drug. It is an antianginal and antiarrhythmic drug. It increases the duration of ventricular and atrial muscle action by inhibiting Na,K-activated myocardial adenosine triphosphatase. There is a resulting decrease in heart rate and in vascular resistance. [PubChem]The antiarrhythmic effect of amiodarone may be due to at least two major actions. It prolongs the myocardial cell-action potential (phase 3) duration and refractory period and acts as a noncompetitive a- and b-adrenergic inhibitor.

Dihydroergotamine

C33H37N5O5 (583.2795)


Dihydroergotamine is only found in individuals that have used or taken this drug. It is a 9,10alpha-dihydro derivative of ergotamine. It is used as a vasoconstrictor, specifically for the therapy of migraine disorders. [PubChem]Two theories have been proposed to explain the efficacy of 5-HT1D receptor agonists in migraine: 1) activation of 5-HT1D receptors located on intracranial blood vessels, including those on arterio-venous anastomoses, leads to vasoconstriction, which correlates with the relief of migraine headache and 2) activation of 5-HT1D receptors on sensory nerve endings of the trigeminal system results in the inhibition of pro-inflammatory neuropeptide release.

Potassium

Liver regeneration factor 1

K+ (38.9637)


Potassium is an essential electrolyte. Potassium balance is crucial for regulating the excitability of nerves and muscles and so critical for regulating contractility of cardiac muscle. Although the most important changes seen in the presence of deranged potassium are cardiac, smooth muscle is also affected with increasing muscle weakness, a feature of both hyperkalaemia and hypokalaemia. Physiologically, it exists as an ion in the body. Potassium (K+) is a positively charged electrolyte, cation, which is present throughout the body in both intracellular and extracellular fluids. The majority of body potassium, >90\\%, are intracellular. It moves freely from intracellular fluid (ICF) to extracellular fluid (ECF) and vice versa when adenosine triphosphate increases the permeability of the cell membrane. It is mainly replaced inside or outside the cells by another cation, sodium (Na+). The movement of potassium into or out of the cells is linked to certain body hormones and also to certain physiological states. Standard laboratory tests measure ECF potassium. Potassium enters the body rapidly during food ingestion. Insulin is produced when a meal is eaten; this causes the temporary movement of potassium from ECF to ICF. Over the ensuing hours, the kidneys excrete the ingested potassium and homeostasis is returned. In the critically ill patient, suffering from hyperkalaemia, this mechanism can be manipulated beneficially by administering high concentration (50\\%) intravenous glucose. Insulin can be added to the glucose, but glucose alone will stimulate insulin production and cause movement of potassium from ECF to ICF. The stimulation of alpha receptors causes increased movement of potassium from ICF to ECF. A noradrenaline infusion can elevate serum potassium levels. An adrenaline infusion, or elevated adrenaline levels, can lower serum potassium levels. Metabolic acidosis causes a rise in extracellular potassium levels. In this situation, excess of hydrogen ions (H+) are exchanged for intracellular potassium ions, probably as a result of the cellular response to a falling blood pH. Metabolic alkalosis causes the opposite effect, with potassium moving into the cells. (PMID: 17883675) [HMDB].
