Prazosin

Prazosin is a prototype selective a antagonist dilates both resistance and capacitance vessels; effect on the former predominating. The haemodynamic effects—reduction in t.p.r. and mean BP with only slight decrease in venous return and c.o. are similar to that produced by a direct acting vasodilator. However, there is little reflex cardiac stimulation and renin release

Hydralazine side effects are frequent and mainly due to vasodilatation. 1. The most common hydralazine side effects are facial flushing, conjunctival injection, throbbing headache, dizziness, palpitation, nasal stuffiness, fluid retention, edema, CHF. 2.

Hydralazine Dose

Hydralazine Dose is affected by its pharmacokinetics. Hydralazine is well absorbed orally, and is subjected to first pass metabolism in liver. The chief metabolic pathway is acetylation which exhibits a bimodal distribution in the population there are slow and fast acetylators. Bioavailability is higher in slow acetylators, but these patients are more prone to develop

Hydralazine

Hydralazine or Dihydralazine is a directly acting arteriolar vasodilator with little action on venous capacitance vessels; reduces t.p.r. It causes greater reduction of diastolic than systolic BP. Reflex compensatory mechanisms are evoked which cause tachycardia, increase in c.o. and renin release — increased aldosterone — Na and water retention. The disproportionate cardiac stimulation appears to

Reserpine

Reserpine is an alkaloid from the roots of Rauwofia serpentina (sarpgandha) indigenous to India which has been used in ‘Ayurvedic’ medicine for centuries. The pure alkaloid was isolated in 1955 and later formed to act by causing CA and 5-HI depletion. Reserpine was a popular antihypertensive of the late 1950s and early 1960s, but is

Guanethidine

Guanethidine is an adrenergic neural blocker that has been used for treating hypertension. Guanethidine is a polar guanidine compound which is taken up into the adrenergic nerve endings by active amine transport, and has three important facets of action: (a) It displaces NA (noradrenaline) from storage granules stoichiometrically. (b) Inhibits nerve impulse coupled release of

Antihypertensive drug

Antihypertensive drug refers to the important class of drugs used for treating blood pressure. They have remarkably improved in the last 50 years. Different classes of drugs have received prominence with passage of time in this period. Before 1950 hardly any effective and tolerated antihypertensive drug was available. Veratrum and Sod. thiocyanate could lower BP,

Antihypertensives

Antihypertensives are drugs used to lower BP in hypertension. Hypertension is a very common disorder, particularly past middle age and hence antihypertensives are very commonly employed drugs in medical practice.. It is not a disease in itself, but is an important risk factor for cardiovascular mortality and morbidity. The cut off manometric reading between normotensives
