直接作用于肾素 - 血管紧张素系统的药物可以对发育中的胎儿造成损伤和死亡。
肾素由肾响应于血容量和肾灌注的减少而分泌。肾素裂解血管紧张素原以形成无活性的十肽血管紧张素I（Ang I）。 Ang I通过血管紧张素转换酶（ACE）和非ACE途径转化为活性八肽血管紧张素II（Ang II）。 Ang II是强大的血管收缩剂，并导致从肾上腺髓质和前功能性神经末梢释放儿茶酚胺。它还促进醛固酮分泌和钠重吸收。在一起，这些影响增加血压。 Ang II也抑制肾素释放，从而向系统提供负反馈。这个周期，从肾素通过血管紧张素到醛固酮及其相关的负反馈回路，被称为肾素 - 血管紧张素 - 醛固酮系统（RAAS）。阿利吉仑是直接肾素抑制剂，降低血浆肾素活性（PRA）并抑制血管紧张素原转化为Ang I.阿利吉仑是否影响其它RAAS组分，例如ACE或非ACE途径，是未知的。
所有抑制RAAS的药剂，包括肾素抑制剂，抑制负反馈回路，导致血浆肾素浓度的补偿性升高。当在用ACE抑制剂和ARB治疗期间发生这种上升时，结果是PRA水平增加。然而，在用阿利吉仑治疗期间，阻断增加的肾素水平的作用，使得无论阿利吉仑用作单一疗法还是与其它抗高血压药联合使用，PRA，Ang I和Ang II均降低。
HCTZ是噻嗪类利尿剂。噻嗪类影响电解质再吸收的肾小管机制，以大约相等的量直接增加钠和氯化物的排泄。间接地，HCTZ的利尿作用降低血浆体积，随之增加血浆肾素活性，增加醛固酮分泌，增加尿钾损失和血清钾降低。肾素 - 醛固酮联系由血管紧张素II介导，因此阻断血管紧张素II的产生或功能的试剂的共同给药倾向于逆转与这些利尿剂相关的钾损失。

This product is used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.This product contains 2 medications. Aliskiren works by relaxing blood vessels so blood can flow more easily. Hydrochlorothiazide is called a "water pill" (diuretic) and causes your body to get rid of extra salt and water. This effect may increase the amount of urine you make when you first start the medication.

Your doctor may direct you to start taking the individual medications first, and then switch you over to this combination product if this is the best dose combination for you.
