Description
Sources: http://www.medicines.ie/medicine/2178/SPC/Arelix+Tablets+6mg/

Piretanide (INN, trade names Arelix, Eurelix, Tauliz) has been synthesized in 1973 at Hoechst AG (Germany) as a loop diuretic[2] compound by using a then-new method for introducing cyclic amine residues in an aromatic nucleus in the presence of other aromatically bonded functional groups. Studies of piretanide in rats and dogs in comparison with other high-ceiling diuretics such as furosemide and bumetanide found a more suitable dose/response rate (regression line) and a more favourable sodium/potassium excretion ratio. These findings led eventually to clinical studies in man and finally to the introduction as a saluretic and antihypertensive medication in Germany, France, Italy and other countries.

Sample Use Guides

In Vivo Use Guide

Oedema: The usual initial adult dose is 6mg daily, adjusted according to response to a maximum of 30mg. An initial dose of 3mg may be sufficient in some patients. Hypertension: The usual initial adult dose is 6mg daily in mild to moderate hypertension. This dose should be continued for 2-4 weeks then increased if necessary at 2-4 week intervals to a maximum of 18mg daily. The maintenance dose is usually 6mg daily.

Route of Administration: Oral

In Vitro Use Guide

To investigate the voltage and external Cl− concentration dependence of channel block, we used voltage-ramp protocols to acquire current–voltage (I–V) relationships To explore the time dependence of blockade, we bathed membrane patches in symmetrical Cl−-rich solutions and stepped voltage first from 0 to −100 mV and then from −100 to +100 mV before returning to 0 mV; the duration of each voltage step was 250 ms. We averaged multiple current records (5–30) acquired in the absence and presence of drugs before subtracting basal currents with no active channels recorded in the absence of PKA (75 nM) and ATP (1 mM) to isolate macroscopic CFTR Cl− currents.
