Class I: Fast sodium (Na) channel blockers

  • Ia -Quinidine, procainamide, disopyramide (depress phase 0, prolonging repolarization)
  • Ib -Lidocaine, phenytoin, mexiletine (depress phase 0 selectively in abnormal/ischemic tissue, shorten repolarization)

Class 1 antiarrhythmic agents can suppress abnormal automaticity by decreasing the slope of phase 4, which is generated by pacemaker currents. The mechanism for this is not understood and is unrelated to blocking fast sodium channels. Indirect vagal effects

Class 1C antiarrhythmic drugs in atrial fibrillation and coronary artery disease In a limited population of AF patients with preserved left ventricle function and PET-CFC indicating occult CAD, treatment with 1C AADs appears not to increase mortality. A larger study would be required to confidently assess the safety of these drugs in this context.

Sodium-channel blockers comprise the Class I antiarrhythmic compounds according to the Vaughan-Williams classification scheme. These drugs bind to and block the fast sodium channels that are responsible for the rapid depolarization (phase 0) of fast-response cardiac action potentials. This type of action potential is found in non-nodal, ...

The five main classes in the Vaughan Williams classification of antiarrhythmic agents are: Class I agents interfere with the sodium (Na +) channel. Class II agents are anti- sympathetic nervous system agents. Most agents in this class are beta blockers. Class III agents affect potassium (K +) ...

landmark classification of antiarrhythmic drugs based on the actions of these drugs on cardiac action poten-tial (AP) components and their relationship to arrhyth-mias.1,2 This classification proved, and remains, central to clinical management. Thus, Class I drugs produce moderate (Ia), weak (Ib), or marked (Ic) Na+ channel

FAQ
📚
Stimulants including cocaine, meth, and ADHD medications are detectable for about 2 or 3 days. Benzodiazepines and MDMA generally flag a urine test for up to 4 days after last dose. Marijuana stays in the system a bit longer, with amounts being detectable for between 1 and 7 days after last use.
📚
To get high without using drugs, pick your favorite kind of exercise, like running, swimming, rowing, or biking, and try pushing yourself for a prolonged or extra difficult session to release endorphins, which make you feel naturally high. Alternatively, try breathing techniques to feel naturally high.
📚
However, according to the U.S. Food and Drug Administration, some average times that drugs will continue to show up in a urine drug test include the following: [1] Heroin: 1-3 days. Cocaine: 2-3 days. Marijuana/THC: 1-7 days. Meth: 2-3 days. MDMA: 2-4 days.
📚
More than 70,000 Americans died from drug-involved overdose in 2019, including illicit drugs and prescription opioids. The figure above is a bar and line graph showing the total number of U.S. drug overdose deaths involving any illicit or prescription opioid drug from 1999 to 2019.
📚
Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body. This allows the drugs to attach onto and activate the neurons.

📚
Most drugs of abuse stay in the body for at least a few days after the last use and are traceable with urine tests. Opioids like heroin and oxycodone are detectable for between 1 and 3 days after last use. Stimulants including cocaine, meth, and ADHD medications are detectable for about 2 or 3 days.
