Teofilin/efedrin
Teofilin/efedrin (INN)[1] adalah formulasi kombinasi dosis tetap dari teofilin, suatu antagonis reseptor adenosin; dengan efedrin, suatu agen pelepas norepinefrin dan agen simpatomimetik yang bekerja secara tidak langsung; yang telah digunakan sebagai bronkodilator dalam pengobatan asma dan sebagai dekongestan hidung.[2][3][4][5][6][7][8][9] Obat ini pertama kali dipelajari dan digunakan untuk mengobati asma pada tahun 1930-an atau 1940-an dan kombinasi kedua obat tersebut kemudian digunakan secara luas.[10][11][12] Rasio teofilin dan efedrin 5:1 biasanya digunakan dalam kombinasi obat-obatan tersebut.[13] Penelitian selanjutnya menemukan bahwa kombinasi tersebut tidak lebih efektif untuk asma daripada teofilin saja tetapi menghasilkan lebih banyak efek samping.[14][15][16][17]
Kombinasi teofilin, efedrin, dan fenobarbital juga telah banyak digunakan untuk mengobati asma.[18][19][20][21] Banyak kombinasi tersebut telah dipasarkan dengan berbagai nama merek. Teofilin juga telah dipasarkan dalam kombinasi dengan simpatomimetik serupa efedrin lainnya seperti rasefedrin dan pseudoefedrin serta dengan barbiturat lainnya seperti amobarbital dan butabarbital.[22] Kombinasi teofilin, efedrin, dan hidroksizin telah dipasarkan juga.[23][24][25] Kombinasi teofilin, efedrin, dan barbiturat kemudian dihapuskan demi kombinasi teofilin dan efedrin saja.[26][27] Kombinasi dosis tetap teofilin dan efedrin ditinggalkan setelah tahun 1970-an karena tidak memungkinkan titrasi dosis dalam terapi asma akibat toksisitas efedrin.[28]
Efek teofilin/efedrin sebagai obat peningkat performa dalam latihan fisik dan olahraga telah dipelajari.[29][30] Penggunaan kombinasi teofilin/efedrin telah menyebabkan diskualifikasi atlet elit karena efedrin dilarang dalam olahraga kompetitif.[31]
