Trospium Chloride




Trospium Chloride Tablets, 20 mg

DESCRIPTION


Trospium Chloride is a quaternary ammonium compound with the chemical name of Spiro[8­azoniabicyclo[3,2,1]octane - 8,1' - pyrrolidinium] - 3 - [(hydroxydiphenylacetyl)oxy] - ,chloride(1α, 3β, 5α). The empirical formula of Trospium Chloride is C25H30ClNO3 and its molecular weight is 427.97. The structural formula of Trospium Chloride is represented below:



Trospium Chloride is a fine, colorless to slightly yellow, crystalline solid. The compound’s solubility in water is approximately 1 g/2 mL.


Each Trospium Chloride tablet contains 20 mg of Trospium Chloride and is to be given orally. Each tablet also contains the following inactive ingredients: microcrystalline cellulose, lactose monohydrate, corn starch, povidone, croscarmellose sodium, colloidal silicon dioxide, magnesium stearate, sucrose, copovidone, titanium dioxide, polyethylene glycol 6000, talc, hypromellose, macrogol, iron oxide yellow, iron oxide red.



CLINICAL PHARMACOLOGY


Trospium Chloride is a muscarinic antagonist.


Trospium Chloride antagonizes the effect of acetylcholine on muscarinic receptors in cholinergically innervated organs including the bladder. Its parasympatholytic action reduces the tonus of smooth muscle in the bladder. Receptor assays showed that Trospium Chloride has negligible affinity for nicotinic receptors as compared to muscarinic receptors at concentrations obtained from therapeutic doses.



Pharmacodynamics


Placebo-controlled studies employing urodynamic variables were conducted in patients with conditions characterized by involuntary detrusor contractions. The results demonstrate that Trospium Chloride increases maximum cystometric bladder capacity and volume at first detrusor contraction.



Pharmacokinetics


Absorption:

After oral administration, less than 10% of the dose is absorbed. Mean absolute bioavailability of a 20 mg dose is 9.6% (range: 4.0 to 16.1%). Peak plasma concentrations (Cmax) occur between 5 to 6 hours post-dose. Mean Cmax increases greater than dose-proportionally; a 3-fold and 4-fold increase in Cmax was observed for dose increases from 20 mg to 40 mg and from 20 mg to 60 mg, respectively. AUC exhibits dose linearity for single doses up to 60 mg. Trospium Chloride exhibits diurnal variability in exposure with a decrease in Cmax and AUC of up to 59% and 33%, respectively, for evening relative to morning doses.


Effect of Food:

Administration with a high fat meal resulted in reduced absorption, with AUC and Cmax values 70 to 80% lower than those obtained when Trospium Chloride was administered while fasting. Therefore, it is recommended that Trospium Chloride should be taken at least one hour prior to meals or on an empty stomach. (See DOSAGE AND ADMINISTRATION and PRECAUTIONS: Information for Patients).


Distribution:

Protein binding ranged from 50 to 85% when concentration levels of Trospium Chloride (0.5 to 50 ng/mL) were incubated with human serum in vitro. The 3H-Trospium Chloride ratio of plasma to whole blood was 1.6:1. This ratio indicates that the majority of 3H-Trospium Chloride is distributed in plasma. The apparent volume of distribution for a 20 mg oral dose is 395 (± 140) liters.


Metabolism:

The metabolic pathway of trospium in humans has not been fully defined. Of the 10% of the dose absorbed, metabolites account for approximately 40% of the excreted dose following oral administration. The major metabolic pathway is hypothesized as ester hydrolysis with subsequent conjugation of benzylic acid to form azoniaspironortropanol with glucuronic acid. Cytochrome P450 is not expected to contribute significantly to the elimination of trospium. Data taken from in vitro human liver microsomes investigating the inhibitory effect of trospium on seven cytochrome P450 isoenzyme substrates (CYP1A2, 2A6, 2C9, 2C19, 2D6, 2E1, and 3A4) suggest a lack of inhibition at clinically relevant concentrations.


Excretion:

The plasma half-life for Trospium Chloride following oral administration is approximately 20 hours. After oral administration of an immediate-release formulation of 14 C-Trospium Chloride, the majority of the dose (85.2%) was recovered in feces and a smaller amount (5.8% of the dose) was recovered in urine; 60% of the radioactivity excreted in urine was unchanged trospium.


The mean renal clearance for trospium (29.07 L/hour) is 4-fold higher than average glomerular filtration rate, indicating that active tubular secretion is a major route of elimination for trospium. There may be competition for elimination with other compounds that are also renally eliminated (See PRECAUTIONS: Drug Interactions).


A summary of mean (± standard deviation) pharmacokinetic parameters for a single 20 mg dose of Trospium Chloride is provided in Table 1.

Pharmacokinetics in Special Populations

Age:


Age did not appear to significantly affect the pharmacokinetics of Trospium Chloride, however, increased anticholinergic side effects unrelated to drug exposure were observed in patients ≥ 75 years of age. (See PRECAUTIONS: Geriatric Use and DOSAGE AND ADMINISTRATION ).



Pediatric:

The pharmacokinetics of Trospium Chloride were not evaluated in pediatric patients.



Gender:

Studies comparing the pharmacokinetics in different genders had conflicting results. When a single 40 mg Trospium Chloride dose was administered to 16 elderly subjects, exposure was 45% lower in elderly females compared to elderly males. When 20 mg Trospium Chloride was dosed twice daily for 4 days to 6 elderly males and 6 elderly females (60 to 75 years), AUC and Cmax were 26% and 68% higher, respectively, in females without hormone replacement therapy than in males.



Race:


Pharmacokinetic differences due to race have not been studied.



Renal Impairment:


Severe renal impairment significantly altered the disposition of Trospium Chloride. A 4.2-fold and 1.8-fold increase in mean AUC0-∞ and mean Cmax, respectively, and the appearance of an additional elimination phase with a long half-life (~33 hr) was detected in patients with severe renal impairment (creatinine clearance < 30 mL/min) compared with healthy, nearly age-matched subjects. The different pharmacokinetic behavior of Trospium Chloride in patients with severe renal impairment necessitates adjustment of dosage frequency. The pharmacokinetics of Trospium Chloride have not been studied in people with creatinine clearance ranging from 30 to 80 mL/min). (See PRECAUTIONS: General and DOSAGE AND ADMINISTRATION).



Hepatic Impairment:


There is no information regarding the effect of severe hepatic impairment on exposure to Trospium Chloride. In a study of patients with mild (Child-Pugh score 5 to 6) and with moderate (Child-Pugh score 7 to 8) hepatic impairment, given 40 mg of immediate-release Trospium Chloride, mean Cmax increased 12% and 63%, respectively, and mean AUC0-∞ decreased 5% and 15%, respectively, compared to healthy subjects. The clinical significance of these findings is unknown. Caution should be used when administering Trospium Chloride to patients with moderate and severe hepatic impairment. (See PRECAUTIONS: General).



Electrophysiology


The effect of 20 mg twice daily and up to 100 mg twice daily Trospium Chloride on QT interval was evaluated in a single-blind, randomized, placebo and active (moxifloxacin 400 mg once daily) controlled 5 day parallel trial in 170 male and female healthy volunteer subjects aged 18 to 45 years. The QT interval was measured over a 24-hour period at steady state. The 100 mg twice daily dose of Trospium Chloride was chosen because this achieves the Cmax expected in severe renal impairment. Trospium Chloride was not associated with an increase in individual corrected (QTcI) or Fridericia corrected (QTcF) QT interval at any time during steady state measurement, while moxifloxacin was associated with a 6.4 msec increase in QTcF.


In this study, asymptomatic, non-specific T wave inversions were observed more often in subjects receiving Trospium Chloride than in subjects receiving moxifloxacin or placebo following five days of treatment. This finding was not observed during routine safety monitoring in 2 other placebo-controlled clinical trials in 591 Trospium Chloride-treated overactive bladder patients (See CLINICAL STUDIES ). The clinical significance of T wave inversion in this study is unknown. Trospium Chloride is associated with an increase in heart rate that correlates with increasing plasma concentrations. In the study described above, Trospium Chloride demonstrated a mean increase in heart rate compared to placebo of 9.1 bpm for the 20 mg dose and of 18.0 bpm for the 100 mg dose. In the two U.S. placebo-controlled trials in patients with overactive bladder, the mean increase in heart rate compared to placebo in Study 1 was observed to be 3.0 bpm and in Study 2 was 4.0 bpm.



CLINICAL STUDIES


Trospium Chloride was evaluated for the treatment of patients with overactive bladder who had symptoms of urinary frequency, urgency, and urge incontinence in two U.S. 12-week, placebo-controlled studies and one 9-month open label extension.


Study 1 was a randomized, double-blind, placebo-controlled, parallel-group study in 523 patients. A total of 262 patients received Trospium Chloride 20 mg twice daily and 261 patients received placebo. The majority of patients were Caucasian (85%) and female (74%) with a mean age of 61 years (range: 21 to 90 years). Entry criteria required that patients have urge or mixed incontinence (with a predominance of urge), urge incontinence episodes of at least 7 per week, and greater than 70 micturitions per week. The patient’s medical history and urinary diary during the treatment-free baseline confirmed the diagnosis. Reductions in urinary frequency, urge incontinence episodes and urinary void volume for placebo and Trospium Chloride treatment groups are summarized in Table 2 and Figures 2 and 3.

INDICATIONS AND USAGE


Trospium Chloride tablets, a muscarinic antagonist, are indicated for the treatment of overactive bladder with symptoms of urge urinary incontinence, urgency, and urinary frequency.



CONTRAINDICATIONS


Trospium Chloride is contraindicated in patients with urinary retention, gastric retention, or uncontrolled narrow-angle glaucoma and in patients who are at risk for these conditions.Trospium Chloride is also contraindicated in patients who have demonstrated hypersensitivity to the drug or its ingredients.



Warnings


Angioedema of the face, lips, tongue and/or larynx has been reported with Trospium Chloride. In one case, angioedema occurred after the first dose. Angioedema associated with upper airway swelling may be life threatening. If involvement of the tongue, hypopharynx, or larynx occurs, Trospium Chloride should be promptly discontinued and appropriate therapy and/or measures necessary to ensure a patent airway should be promptly provided.



PRECAUTIONS



General


Risk of Urinary Retention:

Trospium Chloride should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention.


Decreased Gastrointestinal Motility:

Trospium Chloride should be administered with caution to patients with gastrointestinal obstructive disorders because of the risk of gastric retention (See CONTRAINDICATIONS ). Trospium Chloride, like other anticholinergic drugs, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as ulcerative colitis, intestinal atony and myasthenia gravis.


Controlled Narrow-angle Glaucoma:

In patients being treated for narrow-angle glaucoma, Trospium Chloride should only be used if the potential benefits outweigh the risks and in that circumstance only with careful monitoring.


Patients with Renal Impairment:

Dose modification is recommended in patients with severe renal impairment (creatinine clearance < 30 mL/min). In such patients, Trospium Chloride should be administered as 20 mg once a day at bedtime (See DOSAGE AND ADMINISTRATION ).


Patients with Hepatic Impairment:

Caution should be used when administering Trospium Chloride in patients with moderate or severe hepatic impairment (See CLINICAL PHARMACOLOGY: Pharmacokinetics in Specific Populations).



Information for Patients


Patients should be informed that Trospium Chloride may produce angioedema which could result in life-threatening airway obstruction. Patients should be advised to promptly discontinue Trospium Chloride and seek immediate medical attention if they experience edema of the tongue, edema of the laryngopharynx, or difficulty breathing.


Patients should be informed that anticholinergic agents, such as Trospium Chloride, may produce clinically significant adverse effects related to anticholinergic pharmacological activity. For example, heat prostration (fever and heat stroke due to decreased sweating) can occur when anticholinergics such as Trospium Chloride are used in a hot environment. Because anticholinergics such as Trospium Chloride may also produce dizziness or blurred vision, patients should be advised to exercise caution. Patients should be informed that alcohol may enhance the drowsiness caused by anticholinergic agents.


Trospium Chloride should be taken 1 hour prior to meals or on an empty stomach. If a dose is skipped, patients are advised to take their next dose 1 hour prior to their next meal.



Drug-Drug Interactions


Trospium Chloride  is metabolized by ester hydrolysis and excreted by the kidneys through a combination of tubular secretion and glomerular filtration. Based on in vitro data, no clinically relevant metabolic drug-drug interactions are expected with trospium. However, some drugs which are actively secreted by the kidney may interact with trospium by competing for renal tubular secretion. Co-administration of 500 mg metformin immediate release tablets twice daily with Trospium Chloride 60 mg extended release tablets reduced the steady-state systemic exposure of trospium by approximately 29% for mean AUC0-24 and by 34% for mean Cmax.


The concomitant use of Trospium Chloride with other antimuscarinic agents that produce dry mouth, constipation, and other anticholinergic pharmacological effects may increase the frequency and/or severity of such effects. Trospium Chloride may potentially alter the absorption of some concomitantly administered drugs due to anticholinergic effects on gastrointestinal motility.


Concomitant use of Trospium Chloride  and digoxin did not affect the pharmacokinetics of either drug.


Drugs Eliminated by Active Tubular Secretion: Although demonstrated in a drug-drug interaction study not to affect the pharmacokinetics of digoxin, Trospium Chloride has the potential for pharmacokinetic interactions with other drugs that are eliminated by active tubular secretion (e.g. procainamide, pancuronium, morphine, vancomycin, and tenofovir).


Coadministration of Trospium Chloride with these drugs may increase the serum concentration of Trospium Chloride and/or the coadministered drug due to competition for this elimination pathway. Careful patient monitoring is recommended in patients receiving such drugs (See CLINICAL PHARMACOLOGY: Excretion).



Drug-Laboratory-Test Interactions


Interactions between Trospium Chloride and laboratory tests have not been studied.



Carcinogenesis, Mutagenesis, Impairment of Fertility


Carcinogenicity studies with Trospium Chloride were conducted in mice and rats for 78 weeks and 104 weeks, respectively, at maximally tolerated doses. No evidence of a carcinogenic effect was found in either mice or rats administered up to 200 mg/kg/day, approximately 9 times the expected clinical exposure levels at the maximum recommended human dose (MRHD) of 40 mg.


Trospium Chloride was not mutagenic nor genotoxic in tests in vitro in bacteria (Ames test) and mammalian cells (L5178Y mouse lymphoma and CHO cells) or in vivo in the rat micronucleus test.


No evidence of impaired fertility was observed in rats administered doses up to 200 mg/kg/day (about 16 times the expected clinical exposure at the MRHD, based on AUC).



Pregnancy:


Teratogenic Effects:

Pregnancy Category C: There are no adequate and well-controlled studies of Trospium Chloride in pregnant women.


Trospium Chloride was not teratogenic at statistically significant levels in rats or rabbits administered doses up to 200 mg/kg/day. This corresponds to systemic exposures up to approximately 9 and 16 times, respectively (based on AUC), the clinical exposure at the maximum recommended human dose (MRHD) of 40 mg. However, in rabbits, one fetus in each of the three treated dose groups (0.5, 0.3, and 16 times the exposures at the MRHD) demonstrated multiple malformations, including umbilical hernia and skeletal malformations. A no effect level (20 mg/kg/day in rats and rabbits) for maternal and fetal toxicity was observed at levels approximately equivalent to the clinical exposure at the MRHD. No developmental toxicity was observed in the offspring of female rats exposed pre- and post-natally to up to 200 mg/kg/day. Trospium Chloride should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.



Nursing Mothers


Trospium Chloride (2 mg/kg PO and 50 μg/kg IV) was excreted, to a limited extent (<1%), into the milk of lactating rats (primarily parent compound). It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Trospium Chloride is administered to a nursing woman.


Trospium Chloride should be used during lactation only if the potential benefit justifies the potential risk to the newborn.



Pediatric Use


The safety and effectiveness of Trospium Chloride in pediatric patients have not been established.



Geriatric Use


Of the 591 patients with overactive bladder who received treatment with Trospium Chloride in the two U.S., placebo-controlled, efficacy and safety studies, 249 patients (42%) were 65 years of age and older.


Eighty-eight Trospium Chloride-treated patients (15%) were ≥75 years of age.


In these 2 studies, the incidence of commonly reported anticholinergic adverse events in patients treated with Trospium Chloride (including dry mouth, constipation, dyspepsia, UTI, and urinary retention) was higher in patients 75 years of age and older as compared to younger patients. This effect may be related to an enhanced sensitivity to anticholinergic agents in this patient population (See CLINICAL PHARMACOLOGY: Pharmacokinetics in Special Populations and DOSAGE AND ADMINISTRATION ). Therefore, based upon tolerability, the dose frequency of Trospium Chloride may be reduced to 20 mg once daily in patients 75 years of age and older.



Adverse Reactions


The safety of Trospium Chloride was evaluated in Phase 2 and 3 controlled clinical trials in a total of 2975 patients, who were treated with Trospium Chloride (N=1673), placebo (N=1056) or active control medications (N=246). Of this total, 1181 patients participated in two, 12-week, Phase 3, U.S., efficacy and safety studies and a 9-month open-label extension. Of this total, 591 patients received Trospium Chloride 20 mg twice daily. In all controlled trials combined, 232 and 208 patients received treatment with Trospium Chloride for at least 24 and 52 weeks, respectively.


In all placebo-controlled trials combined, the incidence of serious adverse events was 2.9% among patients receiving Trospium Chloride 20 mg twice daily and 1.5% among patients receiving placebo. Of these, 0.2% and 0.3% were judged to be at least possibly related to treatment with Trospium Chloride or placebo, respectively, by the investigator.


Table 4 lists treatment emergent adverse events from the combined 12-week U.S. safety and efficacy trials that were judged to be at least possibly related to treatment with Trospium Chloride by the investigator, were reported by at least 1% of patients, and were reported more frequently in the Trospium Chloride group than in the placebo group.


The two most common adverse events reported by patients receiving Trospium Chloride 20 mg twice daily were dry mouth and constipation.


The single most frequently reported adverse event for Trospium Chloride, dry mouth, occurred in 20.1% of Trospium Chloride treated patients and 5.8% of patients receiving placebo. In the two Phase 3 U.S. studies, dry mouth led to discontinuation in 1.9% of patients treated with Trospium Chloride 20 mg twice daily. For the patients who reported dry mouth, most had their first occurrence of the event within the first month of treatment.

OVERDOSAGE



Management of Overdosage


Overdosage with antimuscarinic agents, including Trospium Chloride, can result in severe anticholinergic effects. Supportive treatment should be provided according to symptoms. In the event of overdosage, ECG monitoring is recommended.


A 7-month-old baby experienced tachycardia and mydriasis after administration of a single dose of trospium 10 mg given by a sibling. The baby’s weight was reported as 5 kg. Following admission into the hospital and about 1 hour after ingestion of the trospium, medicinal charcoal was administered for detoxification. While hospitalized, the baby experienced mydriasis and tachycardia up to 230 beats per minute. Therapeutic intervention was not deemed necessary. The baby was discharged as completely recovered the following day.



DOSAGE AND ADMINISTRATION


The recommended dose is 20 mg twice daily.


Trospium Chloride tablets should be dosed at least one hour before meals or given on an empty stomach.


Dosage modification is recommended in the following patient populations:


  • For patients with severe renal impairment (creatinine clearance < 30 mL/min), the recommended dose is 20 mg once daily at bedtime (see PRECAUTIONS: General).

  • In geriatric patients ≥75 years of age, dose may be titrated down to 20 mg once daily based upon tolerability (see PRECAUTIONS: Geriatric Use).
