Causes Of Vasodilation
Difference of Verapamil & Diltiazem? Does Diltiazem cause more Vasodilation? "an intermediate class between phenylalkylamine and dihydropyridines"???
Too many individual: response variables; https://en.wikipedia.org/wiki/Calcium_channel_blocker has reasonable group overview. Be aware: all the calcium channel blockers, except amlodipine (neutral), in outcome tracking databases, ↑mortality. Best outcomes & lowest mortality rates: optimize NMR lipoproteins, HbA1c ≤ 5.0%, ACE inhibitors (Aceon/Altace) or ARBs combined with carvedilol, carefully adjusted to responses. ...Read more
Vasodilation refers to the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, particularly in the large veins, large arteries, and smaller arterioles. The process is essentially the opposite of vasoconstriction, which is the ...Read more
Do IsosorbideMN & Nifedipine cause cerebral vasodilation or constriction? Dothey dilate some of bodys vessels/capllaries/veins and constrict others?
Isdn, nifedipine: These both are blood vessel dilators. They don't cause constriction. ...Read more
?: Do you mean inserting an IV? There would be no effect because medicines that vasodilate tend to work on arterioles, not superficial veins. ...Read more
Alcohol: Alcohol is not a blood thinner- it cause vasodilation.However if you drink significant amount, significant liver impairment/ liver failure/cirrhosis can happen. Besides, alcohol can affect the bone marrow and decease production of blood cells-inc platelet. Spleen enlargement can happen compensating to liver failure. Your risk for bleeding will be high when u have liver failure & low platelet level. ...Read more
No...: Anxiety is usually associated with higher levels of adrenaline like hormones which typically cause constriction of vessels. Prolonged hyperventilation which can be associated with anxiety, can cause changes in ph, calcium and potassium levels which may alter these responses. Veins are much less affected by these changes. ...Read more
Not really: You mean, "Does your brain have that cute little red nose and rosy cheeks" appearance? Although some degree of vasodilation can occur in cerebral vessels...the majority of cerebrovascular dilation or constrictions controlled by the nervous system itself and will not respond to normal levels of alcohol. That is because BP within the confines of the brain are EXTREMELY tightly controlled. ...Read more
Ergometrime n oxytocine used together for postpasturm bleeding. But oxytocin causes vasodilation while erg. Cause vasoconstrict?So how they work?
Muscle contraction: The uterus is a remarkable organ. After stretching to an incredible size (from normal), it then contractss or tightens upon itself to close the large blood vessels developed during pregnancy to prevent excessive bleeding after childbirth. Oxytocin stimulates and enhances this contractile activity ergotamine also causes uterine contractions as well as blood vessel constriction, reducing bleeding. ...Read more
Can prescription or OTC drugs that cause vasodilation worsen peripheral neuropathy? I have had to stop taking norvasc, (amlodipine) garlic, and ginkgo biloba due to this.
Yes, possibly: Peripheral neuropathy often comes from damaged nerves sending aberrant impulses--tingling, pins/needles, burning, cold, or numbness. Vasodilation which increases blood flow to peripheral nerves usually helps restore normal function of the nerves; sometimes an undesirable side effect is for numbness to lessen, unmasking more painful neuropathic sensations. ...Read more
If verapamil is a vasodilator how can it be a headache medicine when vasodilation caused headaches?
What type of medication are the most effective in treating hypotension with arterial or venous vasodilation being the cause of the hypotension ?
Dilatation: Or relaxing of the walls or enlargement or engorgement with blood, of blood vessels, usually small arteries that have muscular walls. These kind of mean the same thing. Blood flow increases through these dilated vessels in response to many stimuli. ...Read more
See below: Vasodilation refers to the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, particularly in the large veins, large arteries, and smaller arterioles. The process is essentially the opposite of vasoconstriction, which is the narrowing of blood vessels. ...Read more
