- Brand Names
- Adempas
- Generic Name
- Riociguat
- DrugBank Accession Number
- DB08931
- Background
Riociguat is a soluble guanylate cyclase (sGC) agonist approved in the USA, Europe and several other regions for patients with group I PAH (pulmonary arterial hypertension) in WHO FC II or III; and for the treatment of patients with inoperable CTEPH (chronic thromboembolic pulmonary hypertension), or persistent/recurrent PH (pulmonary hypertension) after pulmonary endarterectomy in WHO FC II or III. Riociguat is marketed under the brand Adempas® by Bayer HealthCare Pharmaceuticals. Treatment with riociguat costs USD $7,500 for 30 days of treatment.

Pharmacology
- Indication
Riociguat is indicated for the treatment of adults with persistent/recurrent chronic thromboembolic pulmonary hypertension (CTEPH), (WHO Group 4) after surgical treatment, or inoperable CTEPH, to improve exercise capacity and WHO functional class. Riociguat is indicated for the treatment of adults with pulmonary arterial hypertension (PAH), (WHO Group 1), to improve exercise capacity, WHO functional class and to delay clinical worsening. Efficacy was shown in patients on Riociguat monotherapy or in combination with endothelin receptor antagonists or prostanoids. Studies establishing effectiveness included predominately patients with WHO functional class II–III and etiologies of idiopathic or heritable PAH (61%) or PAH associated with connective tissue diseases (25%).

- Mechanism of action
Riociguat is a stimulator of soluble guanylate cyclase (sGC), an enzyme in the cardiopulmonary system and the receptor for nitric oxide (NO). When NO binds to sGC, the enzyme catalyzes synthesis of the signaling molecule cyclic guanosine monophosphate (cGMP). Intracellular cGMP plays an important role in regulating processes that influence vascular tone, proliferation, fibrosis and inflammation. Pulmonary hypertension is associated with endothelial dysfunction, impaired synthesis of nitric oxide and insufficient stimulation of the NO-sGC-cGMP pathway.
Riociguat has a dual mode of action. It sensitizes sGC to endogenous NO by stabilizing the NO-sGC binding. Riociguat also directly stimulates sGC via a different binding site, independently of NO. Riociguat stimulates the NO-sGC-cGMP pathway and leads to increased generation of cGMP with subsequent vasodilation.
Target Actions Organism AGuanylate cyclase soluble subunit alpha-2 agoniststimulatorHumans - Absorption
The pharmacokinetics of riociguant are dose proportional from 0.5 mg to 2.5 mg. The absolute bioavailability is approximately 94%. After oral administration, peak plasma concentrations were achieved within 1.5 hours. Food does not affect the bioavailability of riociguat.
- Volume of distribution
Volume of distribution at steady state = 30 L
- Protein binding
95% with serum albumin and alpha-1–acidic glycoprotein being the main binding components.
- Metabolism
The active metabolite (M1) of riociguat is 1/3 to 1/10 as potent as riociguat.
- Route of elimination
Riociguat is eliminated in the urine (40%) and feces (53%), largely as metabolites.
- Half-life
About 12 hours in patients and 7 hours in healthy subjects.

EMBRYO-FETAL TOXICITY Do not administer Riociguat to a pregnant female because it may cause fetal harm. Females of reproductive potential: Exclude pregnancy before the start of treatment, monthly during treatment, and 1 month after stopping treatment. Prevent pregnancy during treatment and for one month after stopping treatment by using acceptable methods of contraception. For all female patients, Riociguat is available only through a restricted program called the Adempas Risk Evaluation and Mitigation Strategy.

Drug Interaction Integrate drug-drug
interactions in your softwareAbametapir The serum concentration of Riociguat can be increased when it is combined with Abametapir. Abatacept The metabolism of Riociguat can be increased when combined with Abatacept. Abemaciclib Abemaciclib may decrease the excretion rate of Riociguat which could result in a higher serum level. Abiraterone The metabolism of Riociguat can be decreased when combined with Abiraterone. Abrocitinib The serum concentration of Riociguat can be increased when it is combined with Abrocitinib. Acebutolol Acebutolol may increase the hypotensive activities of Riociguat. Aceclofenac The therapeutic efficacy of Riociguat can be decreased when used in combination with Aceclofenac. Acemetacin The therapeutic efficacy of Riociguat can be decreased when used in combination with Acemetacin. Acetylsalicylic acid Acetylsalicylic acid may decrease the antihypertensive activities of Riociguat. Adalimumab The metabolism of Riociguat can be increased when combined with Adalimumab.

- Avoid St. John's Wort. This herb induces the CYP3A4 metabolism of riociguat and may reduce its serum concentration.
- Take separate from antacids. Take at least 1 hour before or after antacids. Aluminum or magnesium hydroxide antacids may reduce riociguat absorption.
- Take with or without food.
