Effectiveness
How Verapamil Hydrochloride Affects Patients
Verapamil is a type of drug that helps to regulate the heart beat, reduce chest pain, and lower blood pressure. It comes in an immediate-release form that needs to be taken 3 or 4 times a day and an extended-release form that can be taken once daily. However, it does decrease the strength of the heart muscle, so it should not be used by people with weakened heart muscles or hypertrophic cardiomyopathy.
How Verapamil Hydrochloride works in the body
Verapamil works by blocking calcium channels in the heart, blood vessels, and other cells. This blocks the influx of calcium, causing the blood vessels to relax, reducing blood pressure and the load on the heart. It also slows the electrical activity of the heart, helping to stabilize a racing heart. It's possible that verapamil also works on other types of calcium channels, potassium channels, and adrenergic receptors, but this isn't clear.
When to interrupt dosage

Verapamil Hydrochloride Toxicity & Overdose Risk
The toxic dose of verapamil in women is 14.4mg/kg and 3.429mg/kg in men. The lethal dose in rats is 150mg/kg and 163mg/kg in mice. There is no antidote for an overdose of verapamil, so treatment focuses on providing supportive care. Symptoms of an overdose may include low blood pressure, slow heart rate, and irregular heartbeat. Patients who have taken a large overdose (up to 9 grams) may experience non-cardiogenic pulmonary edema. To treat an overdose, doctors may recommend gastrointestinal decontamination, cathartics, or bowel irrigation
