Which drugs can cause reflex tachycardia?
The three drugs available in this country are verapamil, diltiazem, and nifedipine. Pharmacological studies have shown that verapamil has the most negative chronotropic and inotropic effects of the three, with nifedipine producing the most vasodilation and having the potential for causing reflex tachycardia.
Why does nifedipine cause reflex tachycardia?
Nifedipine is a dihydropyridine calcium channel blocker, the short acting formulation of which has been associated with reflex sympathetic nervous system (SNS) activation leading to flushing, tachycardia, worsening myocardial ischemia, and cerebrovascular ischemia; therefore only longer acting formulations should be …
Why does hydralazine cause reflex tachycardia?
Hydralazine, which is highly specific for arterial vessels, reduces systemic vascular resistance and arterial pressure. Indirect cardiac stimulation (e.g., tachycardia) occurs with hydralazine administration because of activation of the baroreceptor reflex.
Why ACE inhibitors do not cause reflex tachycardia?
Angiotensin converting enzyme inhibitors decrease blood pressure without causing reflex tachycardia in hypertensives, but do not always do so in normotensives.
What causes reflex tachycardia?
If blood pressure decreases, the heart beats faster in an attempt to raise it. This is called reflex tachycardia. This can happen in response to a decrease in blood volume (through dehydration or bleeding), or an unexpected change in blood flow.
Does prazosin cause reflex tachycardia?
It has been found that, for similar decreases in blood pressure, prazosin causes less reflex tachycardia than non-selective alpha blockers or direct vasodilators, and that it is as efficacious as other conventional antihypertensive agents (alpha-methyldopa, hydralazine, beta blockers, etc.)
Does amlodipine cause reflex tachycardia?
Amlodipine is a dihydropyridine calcium channel blocker that does not cause a reflex increase in heart rate.
What is the most common cause of tachycardia?
Common causes of Tachycardia include: Heart-related conditions such as high blood pressure (hypertension) Poor blood supply to the heart muscle due to coronary artery disease (atherosclerosis), heart valve disease, heart failure, heart muscle disease (cardiomyopathy), tumors, or infections.
Why does prazosin cause tachycardia?
Prazosin-induced tachycardia and renin release were attenuated by propranolol. It appears that prazosin produces renin release and tachycardia via stimulation of the beta-adrenergic adrenoceptor.
Does Norvasc cause rapid heartbeat?
Edema (swelling or a collection of fluid) around the lower legs, particularly the ankles, is the main side effect of Norvasc. Shortness of breath, dizziness, fast or irregular heartbeat, flushing, sleepiness, and wheezing have also been reported.
How does amlodipine affect heart rate?
Amlodipine is a calcium channel blocker. It affects the movement of calcium into the cells of the heart and blood vessels. This relaxes the blood vessels and lowers blood pressure. A lower blood pressure will increase the supply of blood and oxygen to the heart.
What medicine helps tachycardia?
Beta blockers If you’ve been diagnosed with tachycardia, your doctor may prescribe a beta-blocker. Beta-blockers stop the action of the hormone adrenaline. This can relieve your tachycardia by slowing your heart rate. It can also lower your blood pressure and decrease the stress on your heart.
Can You give Me list of drugs that may cause tachycardia?
Nicotine and illegal drug use. Nicotine and illegal drugs, such as amphetamines and cocaine , may profoundly affect the heart and trigger an episode of supraventricular tachycardia.
What medications can cause tachycardia?
Alcohol can also be a trigger, and possibly in smaller amounts than caffeine. Certain medications have been known to trigger the pounding heart rhythm of SVT. These include: Digoxin ( Digitek, Digox, Lanoxin), for treating heart failure. Theophylline (Elixophyllin, Norphyl, Phyllcontin), for treating asthma and other lung problems.
What drugs can cause a gag reflex?
What drugs can cause a gag reflex. There was a recent study between honey and robitussin in coughing, and honey was equally effective at soothing a cough. I agree with Dr. Phophalia (and your friends) that the lisinopril (in fact, all angiotensin converting enzyme inhibitors – ACE Inhibitors) class of drugs can cause an idiopathic (for no apparent reason) cough in some people.
What medications increase heart rate?
Sympathomimetics. Norepinephrine bitartrate works on alpha-adrenergic receptor sites in the body and stimulates the sympathetic nervous system,causing effects similar to what a person experiences when frightened or in danger.
