An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]
The risk of first dose phenomenon may be reduced or eliminated by gradual-dose titration, since the adverse effects of Prazosin are dose-related. [7] This is also the case for Tamsulosin and it may be assumed that the others alpha-1 blockers work in a similar manner, since Tamsulosin is an alpha-1-a blocker and Prazosin is an alpha-1 blocker ...
This postural hypotension usually happens shortly after the first dose is absorbed into the blood and can result in syncope (fainting). Syncope occurs in approximately 1% of patients given an initial dose of 2 mg prazosin or greater. This adverse effect is self-limiting and in most cases does not recur after the initial period of therapy or ...
Doxazosin is usually added to other antihypertensive therapy such as calcium channel antagonists, diuretics, beta-adrenoreceptor antagonists, angiotensin-converting enzyme inhibitors and angiotensin-2 receptor blockers. [7] Doxazosin is generally considered to be safe, well tolerated and effective as an add-on (adjunctive) antihypertensive drug ...
Terazosin, sold under the brand name Hytrin among others, is a medication used to treat symptoms of an enlarged prostate and high blood pressure. [1] For high blood pressure, it is a less preferred option. [1] It is taken by mouth. [1] Common side effects include dizziness, headache, feeling tired, swelling, nausea, and low blood pressure with ...
Doxazosin [5] Prazosin (inverse agonist) [6] Tamsulosin [7] Terazosin [8] Silodosin [9] Selective α 2-adrenergic receptor antagonists include: Atipamezole; Idazoxan; Mirtazapine; Yohimbine; Finally, the agents carvedilol and labetalol are both α and β-blockers. Below are some of the most common drugs used in the clinic.
A dose–response curve is a coordinate graph relating the magnitude of a dose (stimulus) to the response of a biological system. A number of effects (or endpoints) can be studied. The applied dose is generally plotted on the X axis and the response is plotted on the Y axis. In some cases, it is the logarithm of the dose that is plotted on the ...
Equivalent dose is a dose quantity H representing the stochastic health effects of low levels of ionizing radiation on the human body which represents the probability ...
