Brief Summary:
Intramuscular injection and oral solution of tranexamic acid (TXA) would increase its use in situations where administration of intravenous drugs is difficult. The investigators aim to assess the population pharmacokinetics (PK) and pharmacodynamics (PD) of intravenous, intramuscular and oral TXA in women undergoing undergoing caesarean section (CS) with at least one known risk factor for postpartum haemorrhage (PPH)

Condition or disease Intervention/treatment Phase
Pregnancy, High Risk Drug: Tranexamic Acid 100Mg/Ml Inj Vil 10Ml Drug: Tranexamic Acid Oral Solution Drug: Tranexamic Acid Injectable Product Phase 2

Detailed Description:
An open label, randomised controlled trial to assess the pharmacokinetics and pharmacodynamics of intramuscular, intravenous and oral solution administration of tranexamic acid in women giving birth by caesarean section. 120 women (30 receiving oral liquid, 30 receiving intramuscular, 30 receiving intravenous and 30 receiving no TXA who have at least 6 evaluable PK samples will be randomised.

    Concentration of TXA in Maternal blood over time


Secondary Outcome Measures :
  1. Placenta transfer of TXA [ Time Frame: at birth of baby ]
    Concentrations of TXA in placenta cord blood

  2. Placenta transfer of TXA [ Time Frame: within 24 hours of birth ]
    Concentration of neonate TXA

  3. Concentration of D-dimer [ Time Frame: up to 24 hours after randomisation ]
    Maternal blood concentration over time

  4. Maternal blood volume lost [ Time Frame: from incision to 2 hours from CS ]
    total blood loss

  5. frequency of Injection site reaction from IM administration [ Time Frame: from randomisation up to 7 days after ]
    Local reactions at injection site

  6. Number of Adverse events (maternal and neonate) [ Time Frame: from randomisation up to 7 days after ]
    any untoward medical events

  7. Number of women with a clinical diagnosis of PPH [ Time Frame: up to 24 hours after giving birth ]
    total blood loss of >1000 mL or any blood loss sufficient to cause haemodynamic instability or requires treatment
