Interactions between Alfuzosin and Mayzent

The siponimod in Mayzent has a major potential interaction with Cardiovascular Conditions and Disorders.

Siponimod is contraindicated in patients who in the last 6 months experienced myocardial infarction, unstable angina, stroke, TIA, decompensated heart failure requiring hospitalization, or Class III or IV heart failure. It is also contraindicated in presence of Mobitz type II second- degree, third-degree AV block, or sick sinus syndrome, unless the patient has a functioning pacemaker. Siponimod causes a transient decrease in heart rate and atrioventricular conduction delays, and has not been studied in patients with significant QT prolongation (greater than 500 msec) or arrhythmias requiring Class Ia or Class III antiarrhythmic drugs. If treatment with siponimod is considered in these patients or in patients with ischemic heart disease, heart failure, history of myocardial infarction, cerebrovascular disease or uncontrolled hypertension, an advice from a cardiologist should be sought. It is recommended to obtain a baseline EKG, and to monitor patients very closely.

Alfuzosin has a moderate potential interaction with Cataract.

Intraoperative Floppy Iris Syndrome has been observed during cataract surgery in some patients on or previously treated with antiadrenergic agents. If a patient is undergoing cataract surgery, the ophthalmologist should be prepared for possible modifications of the surgical technique (iris hooks, iris dilator rings). There does not appear to be a benefit in stopping antiadrenergic agents therapy prior to the cataracts surgery.

The siponimod in Mayzent has a moderate potential interaction with Central Nervous System Disorders.

Rare cases of posterior reversible encephalopathy syndrome (PRES) have been reported in patients receiving a sphingosine 1-phosphate receptor modulator. It is recommended to promptly schedule a complete physical and neurological examination and should consider an MRI, if a patient develops any unexpected neurological or psychiatric symptoms/signs, any symptom/sign suggestive of an increase of intracranial pressure, or accelerated neurological deterioration. Delay in diagnosis and treatment may lead to permanent neurological sequelae. Exercise care when using this agent in patients with a history of ischemic stroke or cerebral hemorrhage. Treatment should be discontinued if PRES is suspected.

Alfuzosin has a moderate potential interaction with Dehydration.

Peripheral alpha 1- adrenergic receptor blocking agents (aka alpha 1- blockers) cause vasodilation and can produce marked hypotension, especially orthostatic hypotension with syncope or other postural symptoms such as dizziness, lightheadedness, and palpitations. Orthostatic effects are most common during initiation of therapy and often occur within 90 minutes after the first dose. However, they can also occur following a dosage increase or resumption of therapy after an interruption of more than a few days. Agents with alpha 1a specificity, such as tamsulosin, act primarily on the prostate but are not devoid of hypotensive effects. Therapy with peripheral alpha-1 blockers should be administered cautiously in patients with or predisposed to hypotensive or syncopal episodes. Caution is also advised in patients who are dehydrated (e.g., due to severe or prolonged diarrhea or vomiting), since they may be more sensitive to the hypotensive effect of the drugs. Therapy should be initiated with the lowest dosage possible and titrated gradually based on patient response and tolerance in accordance with the individual product package labeling. During initiation or reinstitution of therapy and following an increase in dosage, patients should be advised not to rise abruptly from a sitting or recumbent position and to avoid situations where injury could result if syncope occur. Concomitant use of alcohol, extensive periods of standing, prolonged or intense exercise, and exposure to heat can also precipitate orthostatic hypotension and should be minimized. If dizziness, lightheadedness or palpitations occur, the patient should sit or lie down, and seek medical attention if symptoms are recurrent or bothersome.

The siponimod in Mayzent has a moderate potential interaction with Diabetes Mellitus.

Macular edema was reported in 1.8% of patients receiving siponimod treatment, the majority of cases occurring within the first four months of therapy. Patients with a history of uveitis and patients with diabetes mellitus are at increased risk of macular edema during therapy. An ophthalmic evaluation of the fundus, including the macula, is recommended in all patients before starting treatment and at any time if there is any change in vision while taking siponimod. Patients with diabetes mellitus or a history of uveitis should have regular follow-up examinations during treatment. Continuation of therapy in patients with macular edema has not been evaluated, therefore, a decision on whether or not to discontinue treatment needs to take into account the potential benefits and risks for the individual patients.

The siponimod in Mayzent has a major potential interaction with Heart Disease.

Siponimod is contraindicated in patients who in the last 6 months experienced myocardial infarction, unstable angina, stroke, TIA, decompensated heart failure requiring hospitalization, or Class III or IV heart failure.

Siponimod causes a transient decrease in heart rate and atrioventricular conduction delays, and has not been studied in patients with significant QT prolongation (greater than 500 msec) or arrhythmias requiring Class Ia or Class III antiarrhythmic drugs. If treatment with siponimod is considered in these patients or in patients with ischemic heart disease, heart failure, history of myocardial infarction, cerebrovascular disease or uncontrolled hypertension, an advice from a cardiologist should be sought. It is recommended to obtain a baseline EKG, and to monitor patients very closely.

The siponimod in Mayzent has a major potential interaction with History - Cerebrovascular Disease.

Siponimod is contraindicated in patients who in the last 6 months experienced myocardial infarction, unstable angina, stroke, TIA, decompensated heart failure requiring hospitalization, or Class III or IV heart failure. It is also contraindicated in presence of Mobitz type II second- degree, third-degree AV block, or sick sinus syndrome, unless the patient has a functioning pacemaker. Siponimod causes a transient decrease in heart rate and atrioventricular conduction delays, and has not been studied in patients with significant QT prolongation (greater than 500 msec) or arrhythmias requiring Class Ia or Class III antiarrhythmic drugs. If treatment with siponimod is considered in these patients or in patients with ischemic heart disease, heart failure, history of myocardial infarction, cerebrovascular disease or uncontrolled hypertension, an advice from a cardiologist should be sought. It is recommended to obtain a baseline EKG, and to monitor patients very closely.

The siponimod in Mayzent has a major potential interaction with History - Myocardial Infarction.

Siponimod is contraindicated in patients who in the last 6 months experienced myocardial infarction, unstable angina, stroke, TIA, decompensated heart failure requiring hospitalization, or Class III or IV heart failure. It is also contraindicated in presence of Mobitz type II second- degree, third-degree AV block, or sick sinus syndrome, unless the patient has a functioning pacemaker.

Alfuzosin has a moderate potential interaction with Hypotension.

Peripheral alpha 1- adrenergic receptor blocking agents (aka alpha 1- blockers) cause vasodilation and can produce marked hypotension, especially orthostatic hypotension with syncope or other postural symptoms such as dizziness, lightheadedness, and palpitations. Orthostatic effects are most common during initiation of therapy and often occur within 90 minutes after the first dose.

If dizziness, lightheadedness or palpitations occur, the patient should sit or lie down, and seek medical attention if symptoms are recurrent or bothersome.

The siponimod in Mayzent has a moderate potential interaction with Infection.

Siponimod causes a dose-dependent reduction in peripheral lymphocyte count to 20%-30% of baseline values because of reversible sequestration of lymphocytes in lymphoid tissues. Initiation of treatment should be delayed in patients with severe active infection until resolution. Before initiating treatment with siponimod, results from a recent complete blood count (i.e., within 6 months or after discontinuation of prior therapy) should be reviewed. Effective diagnostic and therapeutic strategies should be employed in patients with symptoms of infection while on therapy. Suspension of treatment should be considered if a patient develops a serious infection.

Alfuzosin has a major potential interaction with Liver Disease.

Alfuzosin is contraindicated for use in patients with moderate or severe hepatic impairment (Child Pugh B and C). The pharmacokinetics of alfuzosin have not been studied in patients with mild hepatic impairment and caution should be exercised if it is administered to such patients.

The siponimod in Mayzent has a moderate potential interaction with Liver Disease.

Elevations of transaminases may occur in siponimod- treated patients, therefore, transaminase and bilirubin levels should be reviewed before initiation of therapy. Patients who develop symptoms suggestive of hepatic dysfunction, such as unexplained nausea, vomiting, abdominal pain, fatigue, anorexia, rash with eosinophilia, or jaundice and/or dark urine during treatment, should have liver enzymes checked. Siponimod should be discontinued if significant liver injury is confirmed. Although there are no data to establish that patients with preexisting liver disease are at increased risk to develop elevated liver function test values when taking siponimod, caution should be exercised when using the medication in patients with a history of significant liver disease.

Alfuzosin has a moderate potential interaction with Long QT Syndrome.

Alfuzosin should be used with caution in patients with acquired or congenital QT prolongation, or who are taking medications that prolong the QT interval.

The siponimod in Mayzent has a moderate potential interaction with Multiple Sclerosis.

Rare cases of severe exacerbation of multiple sclerosis (MS), including disease rebound, have been reported after discontinuation of sphingosine 1-phosphate receptor modulator in MS treated patients. The possibility of severe exacerbation of disease should be considered after stopping treatment with these agents. Patients should be observed for a severe increase in disability upon discontinuation and appropriate treatment should be instituted, as required.

Alfuzosin has a moderate potential interaction with Renal Dysfunction.

Caution should be exercised when alfuzosin is administered in patients with severe renal impairment as safety data is limited on these patients (CrCl < 30 mL/min).

The siponimod in Mayzent has a moderate potential interaction with Skin Cancer.

Cases of malignancies, including skin malignancies have been reported in patients treated with some sphingosine -1-receptor (S1P) receptor modulators. Skin examinations are recommended prior and during treatment in all patients, particularly in those with risk factors for skin cancer. Suspicious skin lesions should be promptly evaluated, and patients at increased risk should wear protective clothing and use sunscreen with high protection factor.

Alfuzosin has a moderate potential interaction with Syncope.

Peripheral alpha 1- adrenergic receptor blocking agents (aka alpha 1- blockers) cause vasodilation and can produce marked hypotension, especially orthostatic hypotension with syncope or other postural symptoms such as dizziness, lightheadedness, and palpitations. Orthostatic effects are most common during initiation of therapy and often occur within 90 minutes after the first dose. However, they can also occur following a dosage increase or resumption of therapy after an interruption of more than a few days. Agents with alpha 1a specificity, such as tamsulosin, act primarily on the prostate but are not devoid of hypotensive effects. Therapy with peripheral alpha-1 blockers should be administered cautiously in patients with or predisposed to hypotensive or syncopal episodes. Caution is also advised in patients who are dehydrated (e.g., due to severe or prolonged diarrhea or vomiting), since they may be more sensitive to the hypotensive effect of the drugs. Therapy should be initiated with the lowest dosage possible and titrated gradually based on patient response and tolerance in accordance with the individual product package labeling. During initiation or reinstitution of therapy and following an increase in dosage, patients should be advised not to rise abruptly from a sitting or recumbent position and to avoid situations where injury could result if syncope occur. Concomitant use of alcohol, extensive periods of standing, prolonged or intense exercise, and exposure to heat can also precipitate orthostatic hypotension and should be minimized. If dizziness, lightheadedness or palpitations occur, the patient should sit or lie down, and seek medical attention if symptoms are recurrent or bothersome.

The siponimod in Mayzent has a moderate potential interaction with Uveitis.

Macular edema was reported in 1.8% of patients receiving siponimod treatment, the majority of cases occurring within the first four months of therapy. Patients with a history of uveitis and patients with diabetes mellitus are at increased risk of macular edema during therapy. An ophthalmic evaluation of the fundus, including the macula, is recommended in all patients before starting treatment and at any time if there is any change in vision while taking siponimod. Patients with diabetes mellitus or a history of uveitis should have regular follow-up examinations during treatment. Continuation of therapy in patients with macular edema has not been evaluated, therefore, a decision on whether or not to discontinue treatment needs to take into account the potential benefits and risks for the individual patients.

The siponimod in Mayzent has a moderate potential interaction with Vaccination.

The use of live attenuated vaccines should be avoided while patients are taking siponimod and for 4 weeks after stopping treatment. Vaccinations may be less effective if administered during treatment. Siponimod treatment discontinuation 1 week prior to and until 4 weeks after a planned vaccination is recommended. Additionally, patients without a healthcare professional confirmed history of chickenpox or without documentation of a full course of vaccination against varicella zoster virus (VZV) should be tested for antibodies to VZV before initiating siponimod treatment. A full course of vaccination for antibody- negative patients with varicella vaccine is recommended prior to commencing treatment, following which initiation of treatment with siponimod should be postponed for 4 weeks to allow the full effect of vaccination to occur.
