Desfesoterodine
Desfesoterodine is a medication used in the treatment of overactive bladder (OAB) with symptoms of urinary incontinence, urgency, and frequency. It is a selective muscarinic receptor antagonist, which works by relaxing the bladder muscles to prevent urgent, frequent, or uncontrolled urination.
Mechanism of Action[edit | edit source]
Desfesoterodine is the active metabolite of fesoterodine, which is a prodrug. Once administered, fesoterodine is rapidly hydrolyzed by nonspecific esterases to its active form, desfesoterodine. Desfesoterodine exerts its effects by inhibiting the muscarinic receptors in the bladder, reducing bladder muscle contractions and increasing bladder capacity.
Pharmacokinetics[edit | edit source]
Desfesoterodine is well absorbed after oral administration. It reaches peak plasma concentrations within a few hours. The drug is primarily metabolized in the liver and excreted in the urine. The half-life of desfesoterodine is approximately 7-8 hours, allowing for once-daily dosing.
