Standar pelayanan kefarmasian di Rumah Sakit terdiri dari pengelolaan sediaan farmasi, alat kesehatan, dan bahan medis habis pakai dan pelayanan farmasi klinik. Kegiatan pelayanan farmasi klinik salah satunya seperti pemantauan terapi obat (PTO) (Depkes RI, 2009). Pemantauan terapi obat (PTO) adalah suatu proses yang mencakup kegiatan untuk memastikan terapi obat yang aman, efektif dan rasional bagi pasien. Kegiatan tersebut mencakup: pengkajian pilihan obat, dosis, cara pemberian obat, respons terapi, reaksi obat yang tidak dikehendaki (ROTD), dan rekomendasi perubahan atau alternatif terapi (Kemenkes RI, 2016). Proses PTO merupakan proses yang komprehensif mulai dari seleksi pasien, pengumpulan data pasien, identifikasi masalah terkait obat, rekomendasi terapi, rencana pemantauan sampai dengan tindak lanjut (Depkes RI, 2009). Proses tersebut harus dilakukan secara berkesinambungan sampai tujuan terapi tercapai. Pelaksanaan pemantauan terapi obat di RSUP Fatmawati telah dilaksanakan sesuai tatalaksana terapi. Berdasarkan hasil yang diperoleh ditemukan beberapa interaksi obat yang digunakan pada pasien G3P0A2 Hamil 26 minggu namun gejala atau reaksi dari interaksi tersebut tidak muncul pada pasien.

Pharmaceutical service standards in hospitals consist of management of pharmaceutical preparations, medical devices and consumable medical materials and clinical pharmacy services. One of the clinical pharmacy service activities is Monitoring drug therapy (Depkes RI, 2009). Monitoring drug therapy is a process that includes activities to ensure safe, effective and rational drug therapy for patients. These activities include: reviewing drug choices, dosages, methods of drug administration, therapeutic response, unwanted drug reactions, and recommendations for changes or alternative therapies (Kemenkes RI, 2016). This process is a comprehensive process starting from patient selection, patient data collection, identification of drug-related problems, therapy recommendations, monitoring plans to follow-up (Depkes RI, 2009). This process must be carried out continuously until the therapeutic goal is achieved.
