Seratrodast is a potent, long-acting, stereospecific thromboxane A2/prostaglandin endoperoxide receptor antagonist. The R-(+)-enantiomer of Seratrodast is the pharmacologically active moiety. Seratrodast appears to exert its anti-inflammatory effects through antagonism of the thromboxane Areceptor (TP receptor). In addition, seratrodast blocks the broncho-constrictor effects of PGF2?, PGD2 and 9?,1l?-PGF2 mediated through activation of thromboxane Areceptor (TP receptor).


Following single and repeated oral administration, seratrodast is rapidly and dose-dependently absorbed. The peak plasma concentrations of seratrodast increase proportionally with dose reaching steady-state concentration within 7 days of administration. Following once-daily doses of 80mg for 15 days in patients with mild to moderate asthma, the peak plasma concentration of Seratrodast is 8.80 ?g/ml with an average Tmax of 2.4 hours. The area under the plasma concentration-time curve (AUC) for Seratrodast is 22.96 ? and the average apparent volume of distribution is 33 litres.

Seratrodast has a high protein binding capacity (more than 99%). It is metabolized to 5-methyl hydroxy seratrodast and 4-hydroxyseratrodast by cytochrome P450 (CYP) isoenzymes. It is also partially (35%) glucuronidated in plasma and may be subjected to enterohepatic recycling.

Following oral administration of 40 to 120 mg/day in healthy subjects, the renal clearance of seratrodast ranges from 5.10 to 8.94 ml/hr (average 7.0 ml/hr) after a single dose and at steady-state respectively. The percentage of the dose excreted as unchanged drug in the urine ranges from 0.42% to 1.37% (average 0.83%) after a single dose and at steady-state. The plasma concentrations decline bi-exponentially with an average half-life of 20 and 36 hours after single and multiple administrations, respectively.


Setra is indicated in

  • Prophylactic management of mild to moderate asthma


  • An average dose of 80 mg once daily is recommended
  • Setra has been shown to be well-tolerated following repeated once-daily oral doses of up to a maximum of 320 mg
  • In elderly patients, the treatment should be started with a lower dose of 40mg/day


  • Hypersensitivity to Seretra or any of the ingredients
  • Patients with hepatic failure


Pregnancy and Lactation

There are no adequate and well-controlled studies in pregnant women. Serena should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Serena should be avoided during lactation.

Pediatric Use (< 18 years of age)

The safety and efficacy of Seretra have not been established in children and should not be used in this age group.


Seretra may lead to an elevation in the levels of the hepatic enzymes. Therefore, it has to be administered with caution in patients with hepatic impairment.


  • Use cautiously with other anti-inflammatory analgesics, cephalosporin antibiotics and drugs that have been reported to cause hemolytic anaemia.
  • As aspirin can compete for serum protein binding, it may increase the concentration of the unbound drug (seratrodast) by 26%.


Adverse reactions are generally rare, but if present, range from mild to moderate in severity.

0.1 to 5% Less than   0.1% (rare)
Hypersensitivity Rash, Itching.
Hepatic Elevated liver enzymes
Gastrointestinal Nausea, loss of appetite, stomach discomfort, abdominal pain, diarrhoea, dry mouth Vomiting
Hematologic Anaemia Thrombocytopenia, epistaxis
Neuropsychiatric Drowsiness, headache Insomnia, tremor, numbness
Other Palpitations, malaise Hot flashes, oedema


There have been no reports of overdosage with Seretra. In cases of overdosage, the stomach should be emptied by aspiration and gastric lavage. Vital parameters should be managed symptomatically.


Store in a cool, dry and dark place. Keep out of reach of children.
