However, for torsemide and bumetanide, their oral bioavailability is consistently higher than 90%. Torsemide has a longer half life in heart failure patients (6 hours) than furosemide (2.7 hours). A 40 mg dose of furosemide is clinically equivalent to a 20 mg dose of torsemide and to a 1 mg dose of bumetanide. [6]
The allocation of a B category does not imply greater safety than C category; Medicines in category D are not absolutely contraindicated during pregnancy (e.g. anticonvulsants) The system, as outlined below, was developed by medical and scientific experts based on available evidence of risks associated with taking particular medicines while ...

Metolazone is frequently ...

[4] [5] The drug must not be combined with strong inhibitors of the liver enzyme CYP3A4 or with the immunosuppressant drug ciclosporin. [4] [5]
[11] [12] [185] These metabolites have much longer elimination half-lives than spironolactone of 13.8 hours, 15.0 hours, and 16.5 hours, respectively, and are responsible for the therapeutic effects of the medication. [11] [12] As such, spironolactone is a prodrug. [243]
