Isoprenaline was discovered in 1940 [5] and was developed in the 1940s. [7] It was first approved for medical use in 1947 in the United States. [15] Isoprenaline was one of the first synthetic sympathomimetic amines, was the first selective β-adrenergic receptor agonist, and was the first major sympathomimetic agent devoid of pressor effects ...
Prior to their discovery, the non-selective beta-agonist isoprenaline was used. The aim of the drug development through the years has been to minimise side effects, achieve selectivity and longer duration of action. The mechanism of action is well understood and has facilitated the development.
The mechanisms of sympathomimetic drugs can be direct-acting (direct interaction between drug and receptor), such as α-adrenergic agonists, β-adrenergic agonists, and dopaminergic agonists; or indirect-acting (interaction not between drug and receptor), such as MAOIs, COMT inhibitors, release stimulants, and reuptake inhibitors that increase the levels of endogenous catecholamines.

An adrenergic agonist is a drug that stimulates a response from the adrenergic receptors.The five main categories of adrenergic receptors are: α 1, α 2, β 1, β 2, and β 3, although there are more subtypes, and agonists vary in specificity between these receptors, and may be classified respectively.
In his famous work [5] Ahlquist chose six agonists, including epinephrine, norepinephrine, α-methyl noradrenaline and isoprenaline, and examined their effects on several organs, including blood vessels and the heart. He found that the six substances possessed different rank orders of potency that differed depending on the tissue. For example ...
Dichloroisoprenaline (DCI), also known as dichloroisoproterenol, was the first beta blocker ever to be developed. It is non-selective for the β 1-adrenergic and β 2-adrenergic receptors.
Example of some 200 mg ibuprofen tablets A 150 ml bottle (100 mg/5 ml dosage) of ibuprofen, sold in Greece. Ibuprofen is used primarily to treat fever (including postvaccination fever), mild to moderate pain (including pain relief after surgery), painful menstruation, osteoarthritis, dental pain, headaches, and pain from kidney stones.
