• S-Sätze Betriebsanweisung:

  S22:Staub nicht einatmen.
  S24/25:Berührung mit den Augen und der Haut vermeiden.

• Verwenden

  Rilmenidine hemifumarate ┬аis an antihypertensive agent that selectively binds nonadrenergic imidazoline-binding site I1 receptor.

• Biologische Aktivität

  rilmenidine is an antihypertensive agent that has been shown to lower arterial pressure in various animal models by inhibiting the tonic activity of sympathoexcitatory neurons in the rostral ventrolateral medulla [1].

• Biochem/physiol Actions

  Selective I1 imidazoline receptor agonist.

• in vitro

  bilateral microinjection of rilmenidine into the c1 area of the rostral ventrolateral medulla (rvl) elicited dose-dependent falls in arterial pressure and heart rate. in rvl, rilmenidine competed with binding to imidazole and α2-adrenergic binding sites with a 30-fold selectivity for the imidazole binding sites [2]. rilmenidine, a new antihypertensive agent, appeared 2.5 and 3.5 times more selective than clonidine and guanfacine, respectively, for medullary ipr sites than for cortical α-adrenoceptors [3]. rilmenidine targeted the nonadrenergic imidazoline-binding site i1 receptor with the ki value of 7.1 nm and demonstrated weaker affinity for the i2 receptor with the ki value of 5.2 μm [4].

• in vivo

  in rat model of hypertension associated with insulin resistance, rilmenidine ameliorated the deleterious effects of a high-fructose diet, such as weight gain, hypertension, and resistance to the effects of insulin [5]. in a mouse model of huntington's disease, rilmenidine induced autophagy, attenuated toxicity of polyglutamine expansions and the signs of disease, reduced the mutant huntingtin fragment levels [6].
