Fesoterodine is a competitive muscarinic receptor antagonist with muscle relaxant and urinary antispasmodic properties. Fesoterodine is rapidly hydrolyzed in vivo into its active metabolite 5-hydroxy methyl tolterodine, which binds and inhibits muscarinic receptors on the bladder detrusor muscle, thereby preventing bladder contractions or spasms caused by acetylcholine. This results in the relaxation of bladder smooth muscle and greater bladder capacity, in addition to a reduction in involuntary muscle contractions and involuntary loss of urine. The active metabolite does not interact with alpha-adrenergic, serotonergic, histaminergic and excitatory amino acid receptors and is eliminated via renal excretion.

4.2 Drug Indication

For the treatment of overactive bladder (with symptoms of urinary frequency, urgency, or urge incontinence).


FDA Label


Treatment of the symptoms (increased urinary frequency and / or urgency and / or urgency incontinence) that may occur in patients with overactive-bladder syndrome.


5 Pharmacology and Biochemistry
5.1 Pharmacology

In-vivo the fesoteridine prodrug is broken down into its active metabolite, 5-hydroxymethyl tolterodine (5-HMT), by plasma esterases. The 5-hydroxymethyl metabolite, which exhibits an antimuscarinic activity. Both urinary bladder contraction and salivation are mediated via cholinergic muscarinic receptors. Therefore, acting as a competitive muscarinic receptor antagonist, fesoterodine ultimately acts to decrease the detrusor pressure by its muscarinic antagonism, thereby decreasing bladder contraction and consequently, the urge to urinate.


5.2 MeSH Pharmacological Classification

Muscarinic Antagonists

Drugs that bind to but do not activate MUSCARINIC RECEPTORS, thereby blocking the actions of endogenous ACETYLCHOLINE or exogenous agonists. Muscarinic antagonists have widespread effects including actions on the iris and ciliary muscle of the eye, the heart and blood vessels, secretions of the respiratory tract, GI system, and salivary glands, GI motility, urinary bladder tone, and the central nervous system. (See all compounds classified as Muscarinic Antagonists.)


Urological Agents

Drugs used in the treatment of urological conditions and diseases such as URINARY INCONTINENCE and URINARY TRACT INFECTIONS. (See all compounds classified as Urological Agents.)

5.4 Absorption, Distribution and Excretion

Absorption

Tmax (5-HMT): 5 hours post-adminitration of fesoterodine. AUC (0,)= 49.5 ngh/ ml Bioavailability, 5-HMT = 52%


Route of Elimination

Renal: 70% of fesoterodine was recovered in urine as 5-HMT; 35% carboxy metabolite; 18% carboxy-N-desisopropylmetabolite, and 1% N-desisopropyl metabolite Fecal: 7% Hepatic: fesoterodine elimination via CYP2D6 and CYP3A4


Volume of Distribution

IV, 5-HMT: 169 L


Clearance

5-HMT, healthy subjects: 14.4 L/h 5-HMT is also secreted into the nephron.


5.5 Metabolism/Metabolites

Metabolized by ubiquitous, nonspecific esterases to transform fesoterodine into 5-HMT Extensive metabolism via CYP2D6 and CYP3A4 into inactive metabolites


5.6 Biological Half-Life

7-8 hours for the active metabolite 5-hydroxymethyl tolterodine


5.7 Mechanism of Action

Fesoterodine, once converted to its active metabolite, 5-hydroxymethyltolterodine, acts as a competitive antagonists at muscarinic receptors. This results in the inhibition of bladder contraction, decrease in detrusor pressure, and an incomplete emptying of the bladder.
