Seratrodast 80mg

Seratrodast 80mg – Quick Overview

Seratrodast 80mg is a thromboxane A2 receptor antagonist used for the prophylactic (preventive) management of mild to moderate bronchial asthma. It works by blocking thromboxane A2 signaling, which reduces airway constriction and inflammation. Seratrodast 80mg is a prescription-only medicine and is not approved by the FDA for use in the United States; it should only be used under a doctor’s supervision where locally available.

Medical Supervision & Regulatory Status

Seratrodast is a thromboxane A2 (TXA2) receptor antagonist that was the first TP receptor antagonist developed as an anti-asthmatic drug, receiving marketing approval in Japan in 1997, and it is currently marketed in Japan and India as an add-on controller therapy for asthma management. Seratrodast 80mg is not approved by the U.S. FDA and is not available in the United States; it is prescription-only in the countries where it is marketed, and use requires physician evaluation and prescription.

Clinical Context

Asthma is a chronic airway condition in which the airways narrow, become inflamed, and produce excess mucus, leading to coughing, wheezing, chest tightness, and difficulty breathing. Left poorly controlled, asthma can significantly limit daily activity and increase the risk of flare-ups.

Thromboxane is a substance produced in the lungs of people with asthma, and when it signals through the thromboxane receptor, it leads to bronchoconstriction and vasoconstriction, contributing to breathing difficulty. Seratrodast 80mg is used as a preventive, long-term controller rather than a rescue treatment for sudden symptoms.

As a TP-receptor antagonist, Seratrodast 80mg is one option doctors may consider for mild-to-moderate asthma management, typically alongside other standard asthma therapies and regular follow-up care.

How Seratrodast 80mg Works

Seratrodast belongs to the thromboxane A2 receptor antagonist drug class. It exerts its anti-inflammatory effects through antagonism of the thromboxane A2 receptor (TP receptor), and the R-(+)-enantiomer of seratrodast is the pharmacologically active moiety.

By inhibiting the thromboxane receptor, Seratrodast 80mg helps block airway inflammation and prevents the bronchoconstriction and vasoconstriction that contribute to asthma symptoms.

After oral administration, seratrodast is rapidly and dose-dependently absorbed, with peak plasma concentrations increasing proportionally with dose and reaching steady state within 7 days of regular use. This supports its role as a daily preventive therapy rather than an as-needed treatment.

What is Seratrodast 80mg?

• Drug Class: Thromboxane A2 (TXA2) receptor antagonist
• Active Ingredient: Seratrodast
• Mechanism: Blocks thromboxane A2 receptor signaling to reduce airway inflammation and bronchoconstriction
• Form: Oral tablet
• Dosing Frequency: Once daily
• Regulatory Status: Prescription-only where marketed (Japan, India, and select Asian markets); not FDA-approved in the United States

Uses / Indications

• Prophylactic Management of Mild to Moderate Asthma: Indicated for the prophylactic management of mild to moderate asthma, helping reduce the frequency and severity of asthma symptoms over time.
• Add-On Controller Therapy: Used as an add-on controller therapy in asthma management, typically alongside other prescribed asthma treatments as directed by a doctor.

How to Use / Dosage

Seratrodast 80mg is generally taken with or without food, once daily, or as advised by a doctor, and should be swallowed whole with a glass of water, without crushing, breaking, or chewing the tablet. A doctor determines the correct dose and duration based on asthma severity. Seratrodast 80mg is not intended for treatment of acute asthma attacks; it is used for long-term, ongoing management rather than immediate symptom relief.

If a dose is missed, it should be taken as soon as remembered unless it is nearly time for the next dose, in which case it should be skipped rather than doubled. Seratrodast 80mg should not be stopped suddenly without medical guidance, as this may result in reduced asthma control.

Side Effects

Most patients tolerate Seratrodast 80mg reasonably well, though side effects can occur and should be discussed with a doctor.

Common side effects may include gastrointestinal disturbance, headache, palpitations, drowsiness, and hypersensitivity reactions.

Serious side effects can include hepatitis and increased liver enzymes, which require prompt medical evaluation if symptoms of liver problems develop.

Emergency Warning Signs — seek immediate medical attention if you experience:

• Yellowing of the skin or eyes, dark urine, or unusual fatigue (possible liver problems)
• Severe abdominal pain or persistent vomiting
• Signs of a severe allergic reaction (swelling, rash, difficulty breathing)
• Sudden worsening of breathing or a severe asthma attack
• Irregular or rapid heartbeat
• Severe or persistent headache with visual changes

Warnings & Precautions

Seratrodast 80mg is contraindicated in patients with hypersensitivity to seratrodast or any of its ingredients, and in patients with hepatic (liver) failure. It may lead to elevation in liver enzyme levels, so it should be administered with caution in patients with hepatic impairment, and periodic liver function monitoring may be recommended by the prescribing doctor.

Regarding drug interactions, use with paracetamol (acetaminophen) or with cephem antibiotics increases the risk of liver damage, and use with aspirin increases the bioavailability of seratrodast. Patients should disclose all current medications, including over-the-counter pain relievers, before starting treatment.

There are no adequate and well-controlled studies of seratrodast in pregnant women, so the drug should be used in pregnancy only if the potential benefits justify the risk to the fetus, and it should not be used during lactation. The safety and efficacy of seratrodast has not been established in children under 18 years of age.

Who Should Not Use This Medication

• Patients with a known hypersensitivity to seratrodast or any tablet ingredient
• Patients with hepatic (liver) failure
• Patients under 18 years of age, in whom safety and efficacy have not been established
• Breastfeeding patients
• Patients experiencing an acute asthma attack (not intended for rescue use)
• Patients without a valid prescription and medical evaluation

Storage Instructions

Store Seratrodast 80mg tablets below 30°C, protected from light and moisture. Keep the container tightly closed. Store out of reach and sight of children and pets, and dispose of unused medication safely rather than in household trash.
