Quick Facts

Property Description
Active ingredient Bepridil (bepridil hydrochloride)
Form Tablet / Capsule
Pharmacological class Calcium Channel Blocker / Antiarrhythmic
Common route Oral (by mouth)
Origin Synthetic compound

A Specialized Regulator for the Heart

Vascol is a prescription medication primarily known as a Calcium Channel Blocker (CCB), and is also recognized as a specialized antiarrhythmic agent. Its core active component is the chemical compound bepridil, which is the International Nonproprietary Name (INN) for the substance. Bepridil acts to regulate the heart's electrical stability.

The medication is designed to help maintain a steady, normal electrical rhythm in the heart muscle.

Vascol is considered an atypical CCB because it influences multiple electrical channels within the heart muscle, a characteristic that differentiates it from older or more common CCBs. This specialized mechanism is tailored for patients requiring precise management of both heart muscle contraction and electrical rhythm. This single-entity drug is manufactured as a synthetic compound and is taken via the oral route, typically as a tablet or capsule, providing a standardized and reliable dosage.

General Purpose and Patient Benefit

The general purpose of Vascol is to lessen the heart’s workload and promote efficient function, a key goal in long-term cardiovascular support. By modulating the entry of ions, such as calcium, into heart cells, the medication reduces the force required for contraction and helps certain blood vessels widen. This action ultimately ensures the heart can pump blood with less strain and consumes less oxygen and energy.

As a cardiovascular regulator, the drug’s fundamental role is to help the heart muscle work more easily and rhythmically.

What side effects are possible with Vascol?

Side Effects and Safety Information

Clinical trials and post-marketing surveillance for products containing bepridil, the active ingredient in Vascol, have established a defined safety profile. This profile identifies a range of adverse reactions, some of which are common and others that are serious and clinically significant.

Adverse Reaction Category Frequency Classification Notable Reactions (Example SOC)
Common ge 1/100 to < 1/10 Dizziness (15%), Headache (11%), Asthenia (10-17%), Nausea (12%)
Uncommon to Rare < 1/100 Palpitations, Insomnia, Dry Mouth, Anorexia, Tremor

Serious and Clinically Significant Adverse Reactions

The most serious safety risk associated with this class of medication is Torsades de Pointes type ventricular tachycardia and other severe cardiac arrhythmias, which can be life-threatening. The risk is dose-related and significantly increases with marked prolongation of the QT interval on an electrocardiogram (ECG), as well as in the presence of hypokalemia (low potassium) or hypomagnesemia (low magnesium).

Other serious events reported have included agranulocytosis (a severe reduction in white blood cells) and rare cases of pulmonary fibrosis.

Safety Restrictions and Monitoring

Safety data indicate that Vascol should be reserved for individuals who have not responded optimally to or are intolerant of other anti-anginal treatments, due to the potential for serious ventricular arrhythmias. Routine monitoring of the ECG for QT interval and assessment of serum potassium levels are mandatory. Caution is also advised when administering the drug to patients with existing bundle branch block or serious hepatic or renal disorders, as the drug is highly metabolized and primarily excreted through the kidneys.

For specific populations, use in breastfeeding mothers is generally not recommended unless the potential benefit justifies the unknown risk to the infant, as the medication is secreted into breast milk.

Overdose and Emergency Response

Overdose and When to Seek Help

The official regulatory documents for bepridil (Vascol) establish a profile centered on severe cardiotoxicity and the mandatory requirement for advanced, specialized supportive care in the event of an overdose.

Overdose Scope

Domain Official Regulatory Statement
Documented overdose presentations Overdose may present as exaggerated adverse reactions, specifically clinically significant hypotension and high-degree atrioventricular (AV) block.
Physiological systems affected Primarily the cardiovascular system, leading to severe electrical and circulatory disturbances.
Emergency-response statements Treatment requires appropriate supportive measures, which may include gastric lavage, beta-adrenergic stimulation, and the use of vasopressor agents.
When immediate medical help is required Close observation in a cardiac care facility for a minimum of 48 hours is recommended due to the potential for severe, life-threatening outcomes.

Overdose Classifications

Classification Official Regulatory Statement
Severity classification Associated with severe cardiac outcomes, including ventricular tachycardia and the risk of Torsades de pointes, classifying the event as life-threatening.
Overdose-context constraints No specific antidote is known; management is strictly limited to symptomatic and supportive treatment.

Resulting Overdose Structure

Official overdose statements:

  • The most severe outcomes of overdose include ventricular tachycardia and high-degree AV block.
  • Monitoring is mandated, specifically involving the QTc interval and the correction of any detected hypokalemia.
  • Specific supportive management includes parenteral calcium solutions, vasopressor agents, and cardioversion, as needed.

Connection to the overall overdose profile (2–4 sentences): Regulatory documents define the bepridil overdose profile by emphasizing severe cardiotoxicity and the potential for circulatory collapse. This documented risk necessitates that patients experiencing overdose seek immediate medical attention to ensure access to the documented procedural interventions and specialized cardiac monitoring over a minimum period of 48 hours.

Therapeutic Uses of Vascol

What Vascol Treats: Main Uses and Benefits

Vascol is a therapeutic agent used for cardiovascular disease, commonly used to help with certain symptoms related to organ-specific functional stress. It is commonly used across conditions presenting with localized discomfort, namely chronic stable angina and certain persistent heart rhythm disturbances.

The medication is generally applied in clinical settings that involve acute or unstable symptom patterns, especially for individuals with angina who may have persistent symptoms despite other management strategies. The therapeutic role contributes to easing the overall symptom load and supports the maintenance of functional stability. This includes being relevant for easing symptoms related to physical discomfort, such as recurrent chest discomfort used when symptoms create noticeable physiological strain, and is applied in addressing symptoms related to heightened physiological activity, such as sustained atrial fibrillation and ventricular tachyarrhythmia.


Quick Fact: Symptom Management Focus

Feature Description
Symptoms it helps manage Recurrent chest discomfort, symptoms of abnormal heart rhythm
Condition Categories Chronic stable angina, relevant in conditions characterized by periods of heightened symptoms

What should I know about interactions with other medicines?

Interactions with other medicines and products

This section describes formally documented interaction patterns for Vascol (bepridil) as stated in government regulatory labeling. The primary area of concern involves agents that affect the heart's electrical stability and conduction.

Contraindicated Combinations

The most significant restriction is the formal contraindication of co-administration with other agents that prolong the QT interval. This includes all Class IA and Class III antiarrhythmic drugs (such as quinidine or procainamide), as well as any other medication known to cause Torsades de Pointes. This prohibition is established due to the risk of severe, additive prolongation of the QT interval.

Documented Pharmacodynamic Effects

Co-administration with Beta-blocking Agents may lead to excessive bradycardia and conduction abnormalities because of their additive effects on cardiac function. An indirect risk is documented when Vascol is combined with potassium-wasting diuretics; the diuretic-induced hypokalemia (low potassium) increases the risk of Bepridil-related ventricular arrhythmias. Furthermore, Ethanol (alcohol) may result in additive effects in lowering blood pressure.

Exposure and Metabolic Interactions

Vascol has been associated with modest increases in the steady-state serum concentrations of Digoxin. A specific drug–food interaction is noted with Grapefruit juice, which may increase the plasma concentrations of Bepridil due to interference with first-pass metabolism.

Mechanism of Action

Bepridil engages a multichannel blockade mechanism by interacting with multiple ion channels, affecting the electrophysiological and contractile processes of the myocardium.

Multi-Channel Blockade and Action Potential Kinetics

This domain involves the simultaneous inhibition of L-type Calcium Channels (CaV1.2), fast inward Sodium Channels (NaV), and specific outward Potassium Channels (IKr, IKs) in the heart muscle. The blockade exhibits a frequency-dependent nature, meaning its inhibitory effect on ion currents is intensified at higher heart rates. This action alters the kinetics of the cardiac action potential, resulting in an increased effective refractory period by slowing conduction and prolonging the repolarization phase.

Dual Regulation of Myocardial Effort

The mechanism exerts a dual, partially offsetting functional consequence on myocardial contraction. The calcium channel blockade restricts calcium influx, which decreases the intrinsic force of myocardial contraction (negative inotropy). Concurrently, Bepridil acts on the intracellular protein Troponin C, enhancing the sensitivity of the muscle filaments to the available calcium. This balance, combined with effects on the vascular smooth muscle that promote vasorelaxation, leads to a reduction in the required myocardial effort and oxygen consumption.

Dosage and Administration Information

How to Use Vascol

Vascol (bepridil hydrochloride) is a medication that is administered orally as a tablet. Its use follows an established protocol concerning dosage initiation, adjustment intervals, and maximum daily intake.

Administration Guideline Guideline
Route Oral (by mouth)
Dosing Frequency Once daily
Initial Daily Dose 200 mg
Maximum Daily Dose 400 mg

The usual starting dose for adults is 200 mg once daily. The typical maintenance range spans from 300 mg to 400 mg daily. The drug is available in strengths of 200 mg, 300 mg, and 400 mg tablets. A defining aspect of its administration is the minimum 10-day waiting period required between any dosage adjustments. This is a procedural constraint to allow the medication to reach necessary stable concentrations in the body before a new dose is evaluated.

Regarding intake conditions, Vascol may be consumed without regard to food—meaning it can be taken with meals or on an empty stomach. For specific populations, while the starting dose for older adults is consistent with younger adults, patients with hepatic impairment (changes in liver function) may require a modification to the initial dosage. The protocol is designed for long-term maintenance use.

Recent Clinical Evidence

Research Evidence / Overview of Studies for Vascol

Evidence for Use in Chronic Stable Angina

Research into Vascol's use has primarily involved short-term randomized controlled trials (RCTs). These are studies where people are randomly assigned to receive either Vascol or an inactive treatment (placebo), allowing researchers to explore how symptoms change over time. The main outcomes research examined related to outcomes reflecting daily functioning or activity level, such as measurements of exercise duration and the time until chest discomfort occurred. Studies also monitored patient-reported outcomes describing perceived discomfort, specifically tracking the weekly number of angina attacks and the amount of short-acting rescue medication recorded.

Research explored short-term symptom changes in adult patients with established chronic stable angina who had persistent symptoms despite other management strategies. The studies reported patterns observed in how symptoms changed in the observed populations during the study period. Research describes patterns observed in measurements of physical activity and functional capacity over defined time intervals.

Evidence for Use in Heart Rhythm Disturbances

Vascol was evaluated in specialized clinical trials and electrophysiological studies related to its electrical properties. Research examined temporary physiological imbalance related to heart rhythm. The outcomes studied related to systemic or functional imbalance and focused heavily on electrical measurements taken from an electrocardiogram (ECG). Specifically, studies monitored a key electrical biomarker called the QTc interval and tracked the occurrence of certain types of fast or irregular heart rhythms (ventricular tachyarrhythmias).

Research describes the changes measured during the study period regarding the heart's electrical parameters. The evidence provides context related to observed symptom patterns and the heart's electrical parameters.

Research Gaps and Areas of Uncertainty

One major limitation is that the long-term effects are not fully established regarding major clinical outcomes like preventing heart attacks or overall survival. The primary research was designed to look at outcomes related to physical discomfort and daily functioning, not these larger endpoints. Due to the short structure of the research, long-term effects are not fully established, and there is limited information for long-term outcomes related to major cardiovascular events. Furthermore, data for certain groups remain insufficient. Overall, the existing evidence provides limited certainty in areas outside of the specific, short-term functional and symptom outcomes initially studied.
