      "claim_text": "past clinical response pattern matters in Losartan because a medicine that worked well but caused a specific problem creates a different decision from one that never achieved the therapeutic objective. For Losartan, documenting what improved, what did not improve, when medication-related problems appeared and whether doses were missed gives the next review something concrete to use. If Losartan is being researched after treatment failure, the useful question is whether the failure reflects dose, adherence, timing, interaction, wrong indication, intolerance or another clinical factor.",
