First synthesized in 1943, lidocaine is a prominent amide-class local anesthetic. The main ingredient in lidocaine is lidocaine hydrochloride, the active chemical compound responsible for its numbing effects. This key component works by temporarily blocking nerve signals to provide pain relief for various medical procedures.

While both affect ion channels in the body, phenytoin is primarily known for its role as a sodium channel blocker, not a calcium channel blocker. A critical distinction lies in their primary target: phenytoin stabilizes inactive sodium channels to control seizures, while calcium channel blockers inhibit the influx of calcium to manage conditions like hypertension and angina.

Mexiletine, an antiarrhythmic drug structurally similar to the anesthetic lidocaine but active orally, primarily works by blocking sodium channels. In the body, this action helps stabilize heart rhythms and can alleviate certain types of nerve-related pain and muscle stiffness by impacting electrical impulses in both cardiac and nervous systems.

In a significant medical breakthrough, the FDA approved Journavx (suzetrigine) in January 2025—the first new class of oral pain medication to come to market in over two decades. This groundbreaking drug directly answers the question, "What is the new painkiller that is not an op?", providing a long-awaited, non-addictive alternative for managing moderate to severe acute pain.

Flecainide is a potent Class IC antiarrhythmic drug used to prevent and treat various irregular heartbeats, including paroxysmal atrial fibrillation and supraventricular tachycardia. This prescription medication works directly on the heart's electrical system to slow nerve impulses and help maintain a normal, stable rhythm. Due to its potency and potential for serious side effects, flecainide is reserved for specific patient populations.

According to the FDA, over 50 million people in the United States suffer from chronic pain, fueling a high demand for safer pain management solutions. Against this backdrop, the recent approval of Journavx, **what is the new drug shown to relieve pain without getting addicted?**, marks a significant milestone in pharmacology, providing a much-needed non-opioid alternative for acute pain.

In January 2025, the U.S. Food and Drug Administration (FDA) approved Journavx (suzetrigine), marking the first new class of oral non-opioid pain medication in over 20 years. This groundbreaking development answers the question, "What is the new painkiller that is not an opioid?", offering a promising alternative for managing moderate to severe acute pain without the addiction risk of traditional opioids.

The U.S. Food and Drug Administration (FDA) approved suzetrigine (brand name Journavx) in January 2025, representing the first novel non-opioid pain medication approved in over two decades. This medication is used for the short-term treatment of moderate to severe acute pain in adults.

According to a 2023 review, lidocaine has reemerged as a second-line therapy for acute sustained ventricular tachyarrhythmias, especially those associated with myocardial ischemia. The question of **what does lidocaine do to the heart** is critical, as its targeted action on sodium channels is key to its therapeutic and adverse effects.

Journavx (suzetrigine) was officially approved by the FDA as a prescription-only medication in January 2025, confirming it is not available for purchase over the counter. This non-opioid drug is specifically indicated for the treatment of moderate-to-severe acute pain in adults and requires a doctor's oversight to ensure safe and effective use.
