You are requested to assess a 38-year-old woman who is in her 38th week of pregnancy. She is scheduled to have a Caesarean section due to fetal distress caused by placental abruption.

During the examination, you observe that she is of average build with a body mass index of 27 kg/m2 and a heart rate of 95 beats per minute. Her blood pressure is 132/78 mmHg, and her respiratory rate is 18 breaths per minute. There is no jugular venous distension, and her apex beat is in the fifth intercostal space. She has a mid-systolic click and a late systolic murmur at the apex that radiates towards the axilla. Apart from the gravid uterus, the rest of her physical examination is unremarkable.

The patient has no significant medical history except for a previous episode of skin wheals and pruritis following the ingestion of amoxicillin. The symptoms resolved after treatment with chlorpheniramine maleate.

What is the most appropriate prophylactic regimen for endocarditis in this patient?
