Moderate drug interactions

Moderate:

treprostinil riociguat

Applies to: treprostinil and riociguat

Riociguat may add to the blood pressure lowering effects of treprostinil.

You may experience headache, dizziness, lightheadedness, fainting, and/or changes in pulse or heart rate. Let your doctor know if you develop these symptoms and they do not go away after a few days or they become troublesome.

You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications.

Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position.

It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition.

It can be intentional, when combining drugs with similar actions adds demonstrated therapeutic benefit — or unintentional, such as when a patient sees multiple prescribers or fills prescriptions at more than one pharmacy, which can lead to adverse effects.

Duplication:

Agents for pulmonary hypertension

The recommended maximum number of medicines in the 'agents for pulmonary hypertension' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'agents for pulmonary hypertension' category:

  • riociguat
  • treprostinil

Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

riociguat Food/Lifestyle

Applies to: riociguat

Chemical substances present in cigarette smoke may reduce the blood levels of riociguat. This means that the medication may be less effective if you smoke during treatment.

Let your doctor know if you are a smoker, or if you start smoking or stop smoking during treatment with riociguat, because the dosage may need to be adjusted.

It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Food may affect the absorption and blood levels of riociguat.

To avoid significant fluctuations in blood levels of the medication, riociguat should be taken about the same time each day consistently either with or without food.

Disease interactions

13 potential interactions Applies to: 9 conditions, including High Blood Pressure, Hypotension, Diverticulitis, Pulmonary Edema, and Liver Disease.

Bleeding Associated with Coagulation Defect

Moderate:

treprostinil

Treprostinil has a moderate potential interaction with Bleeding Associated with Coagulation Defect.

Treprostinil injection inhibits platelet aggregation and increases the risk of bleeding. Close monitoring is recommended when using this agent in patients with bleeding disorders.

Diverticulitis

Moderate:

treprostinil

Treprostinil has a moderate potential interaction with Diverticulitis.

The tablet shell of the manufactured form of treprostinil, Orenitram does not dissolve and can lodge in the diverticulum of patients with diverticulosis. Care should be exercised when using this drug in patient with diverticulosis.

High Blood Pressure

Moderate:

riociguat

Riociguat has a moderate potential interaction with High Blood Pressure.

Riociguat reduces blood pressure. There is a potential for symptomatic hypotension or ischemia in patients with hypovolemia, severe left ventricular outflow obstruction, resting hypotension, autonomic dysfunction, or concomitant treatment with antihypertensive agents. Consider a dose reduction if the patient develops signs or symptoms of hypotension.

Hypotension

Moderate:

riociguat

Riociguat has a moderate potential interaction with Hypotension.

Riociguat reduces blood pressure. There is a potential for symptomatic hypotension or ischemia in patients with hypovolemia, severe left ventricular outflow obstruction, resting hypotension, autonomic dysfunction, or concomitant treatment with antihypertensive agents. Consider a dose reduction if the patient develops signs or symptoms of hypotension.

Moderate:

treprostinil

Treprostinil has a moderate potential interaction with Hypotension.

Treprostinil is a pulmonary and systemic vasodilator. In patients with low systemic arterial pressure, treatment with treprostinil injection may produce symptomatic hypotension. Care should be exercised when using this agent in patients at risk.

Interstitial Lung Disease

Major:

riociguat

Riociguat has a major potential interaction with Interstitial Lung Disease.

Use of riociguat is contraindicated in patients with pulmonary hypertension associated with idiopathic interstitial pneumonias (PH-IIP).

Liver Disease

Major:

treprostinil

Treprostinil has a major potential interaction with Liver Disease.

The use of the extended-release tablet formulation of treprostinil is contraindicated in patients with severe hepatic impairment (Child Pugh Class C). There is a marked increase in the systemic exposure to treprostinil in hepatically impaired patients. It is recommended to start patients with mild hepatic impairment (Child Pugh Class A) at 0.125 mg BID with 0.125 mg BID dose increments every 3 to 4 days and to avoid use of treprostinil in patients with moderate hepatic impairment (Child Pugh Class B).

Moderate:

riociguat

Riociguat has a moderate potential interaction with Liver Disease.

Use of riociguat is not recommended in patients with severe hepatic impairment (Child-Pugh C); safety and efficacy of riociguat have not been demonstrated in this population.

Moderate:

treprostinil

Treprostinil has a moderate potential interaction with Liver Disease.

Severe hepatic impairment (Child Pugh Class C) is a contraindication in patients taking the oral presentation of treprostinil. Treprostinil is substantially metabolized by the liver, primarily by CYP450 2C8. Treprostinil injection clearance is reduced in patients with hepatic insufficiency. In patients with mild or moderate hepatic insufficiency, decrease the initial dose of treprostinil injection to 0.625 ng/kg/min ideal body weight, and monitor closely. Treprostinil injection has not been studied in patients with severe hepatic insufficiency. It is recommended to titrate treprostinil injection slowly in patients with hepatic insufficiency, because such patients will likely be exposed to greater systemic concentrations relative to patients with normal hepatic or renal function.

Pulmonary Edema

Moderate:

riociguat

Riociguat has a moderate potential interaction with Pulmonary Edema.

Use of riociguat, a pulmonary vasodilator, is not recommended in patients with pulmonary veno-occlusive disease (PVOD) as it may significantly worsen cardiovascular status. If signs of pulmonary edema occur, the possibility of associated PVOD should be considered and, if confirmed, treatment should be discontinued.

Pulmonary Impairment

Moderate:

treprostinil

Treprostinil has a moderate potential interaction with Pulmonary Impairment.

The efficacy of treprostinil inhalant has not been established in patients with significant underlying lung disease. Patients with acute pulmonary infections should be carefully monitored to detect any worsening of lung disease and loss of drug effect.

Renal Dysfunction

Moderate:

riociguat

Riociguat has a moderate potential interaction with Renal Dysfunction.

Use of riociguat is not recommended in patients with CrCl less than 15 mL/min; safety and efficacy of riociguat have not been demonstrated in this population.

Moderate:

treprostinil

Treprostinil has a moderate potential interaction with Renal Dysfunction.

Treprostinil and its metabolites are excreted mainly through the urinary route. It is recommended to titrate treprostinil injection slowly in patients with renal insufficiency, because such patients will likely be exposed to greater systemic concentrations relative to patients with normal renal function. No dose adjustments are required in patients with renal impairment. Treprostinil is not cleared by dialysis.
