Salicylate poisoning, also known as aspirin poisoning, is the acute or chronic poisoning with a salicylate such as aspirin. [1] The classic symptoms are ringing in the ears , nausea , abdominal pain , and a fast breathing rate . [ 1 ]
Antihypertensive agents comprise multiple classes of compounds that are intended to manage hypertension (high blood pressure). Antihypertensive therapy aims to maintain a blood pressure goal of <140/90 mmHg in all patients, as well as to prevent the progression or recurrence of cardiovascular diseases (CVD) in hypertensive patients with established CVD.

Labetalol is a beta blocker, or an antagonist of the β-adrenergic receptors. It is specifically a non-selective antagonist of the β 1-and β 2-adrenergic receptors. [17] Labetalol has intrinsic sympathomimetic activity. [17] It is also an antagonist of the α 1-adrenergic receptor, and hence is additionally an alpha blocker.
These medications work through a variety of mechanisms. Labetalol is a beta-blocker with mild alpha antagonism, decreasing the ability of catecholamine activity to increase systemic vascular resistance, while also decreasing heart rate and myocardial oxygen demand.
Aspirin is also used long-term to help prevent further heart attacks, ischaemic strokes, and blood clots in people at high risk. [11] For pain or fever, effects typically begin within 30 minutes. [11] Aspirin works similarly to other NSAIDs but also suppresses the normal functioning of platelets. [11] One common adverse effect is an upset ...
In toxicology, the median lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 is a toxic unit that measures the lethal dose of a given substance. [1] The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration.
Additionally, aspirin induces the formation of NO-radicals in the body, which have been shown in mice to have an independent mechanism of reducing inflammation. This reduces leukocyte adhesion, which is an important step in immune response to infection. There is currently insufficient evidence to show that aspirin helps to fight infection. [18]
