What are the uses of Siponimod?

Mayzent is a sphingosine 1-phosphate (s1p) receptor modulator indicated for the treatment of relapsing forms of multiple sclerosis (ms), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults.

How does Siponimod work?

• Siponimod is an S1P receptor modulator.
• Siponimod binds with high affinity to S1P receptors 1 and 5.
• Siponimod blocks the capacity of lymphocytes to egress from lymph nodes, reducing the number of lymphocytes in peripheral blood.
• The exact mechanism by which siponimod exerts therapeutic effects in multiple sclerosis is unknown, but may involve reduction of lymphocyte migration into the central nervous system.

Who Should Not Use Siponimod?

• Patients with a CYP2C93/3 genotype.
• In the last 6 months, experienced myocardial infarction, unstable angina, stroke, TIA, decompensated heart failure requiring hospitalization, or class III/IV heart failure.
• Presence of Mobitz type II second-degree, third-degree AV block, or sick sinus syndrome, unless patient has a functioning pacemaker.
• Warnings and precautions
• Infections: mayzent may increase the risk. Obtain a complete blood count (cbc) before initiating treatment. Monitor for infection during treatment. Do not start in patients with active infection.
• Macular edema: an ophthalmic evaluation is recommended before starting treatment and if there is any change in vision while taking mayzent. Diabetes mellitus and uveitis increase the risk.
• Bradyarrhythmia and atrioventricular conduction delays: mayzent may result in a transient decrease in heart rate; titration is required for treatment initiation. Consider resting heart rate with concomitant beta-blocker use; obtain cardiologist consultation before concomitant use with other drugs that decrease heart rate.
• Respiratory effects: may cause a decline in pulmonary function. Assess pulmonary function (e.G., spirometry) if clinically indicated.
• Liver injury: obtain liver enzyme results before initiation. Closely monitor patients with severe hepatic impairment. Discontinue if significant liver injury occurs.
• Cutaneous malignancies: periodic skin examination is recommended.
• Increased blood pressure: monitor blood pressure (bp) during treatment.
• Fetal risk: women of childbearing potential should use effective contraception during and for 10 days after stopping mayzent.
