2. The Pharmacy Guild of Australia NSW Branch INCONTINENCE Involuntary loss of urine or stool in sufficient amount or frequency to constitute a social and or health problem.
A heterogeneous condition that ranges in severity from dribbling small amounts of urine to continuous urinary incontinence with concomitant faecal incontinence.
Prevalence increases with age, but it is not part of the normal aging
3. The Pharmacy Guild of Australia NSW Branch The statistics Incontinence occurs in
approximately 50% of nursing home residents
25-30% of community dwelling older women
10-15% of community dwelling older men.
545,000 or 2.8% of the Australian adult population have severe incontinence.
128,800 of the total live in care accomodation; requiring assistance including frequent leakage events and assistance due to mobility limitation
4. The Pharmacy Guild of Australia NSW Branch Urge-common in elderly
Stress
Overflow

TYPES OF INCONTINENCE URGE INCONTINENCE is usually due to detrusor muscle overactivity with leakage of urine because the bladder is perceived to be full. This common in the elderly; it occurs as an isolated event or secondary to local factors, e.g. bladder infection or stones, or to central factors, e.g. stroke, dementia or Parkinsons Disease.
STRESS INCONTINENCE occurs when the intra-abdominal pressure is increased, e.g. after a cough or sneeze and there is a weak pelvic floor or urethral sphincter. It is common in women after childbirth.
OVERFLOW INCONTINENCE occurs with leakage of urine from a full distended bladder. It occurs commonly in men with prostatic obstruction, following spinal cord injury or in women with cystoceles or after gynaecological surgery.
FUNCTIONAL INCONTINENCE. Passage of urine occurs owing to inability to get to a toilet because of disability, e.g. stroke, trauma, the unavailability of toilet facilities or dementia

5. The Pharmacy Guild of Australia NSW Branch Physical examination form local problems, e.g. prostatic enlargement in men, gynaecological disorders in women, and for central problems, eg neurological disorders or dementia
Urine analysis, e.g. glycosuria and culture for UTI
Treatment of contributing causes, e.g. constipation, drug therapy, other co-existing disease MANAGEMENT
6. The Pharmacy Guild of Australia NSW Branch Urge Incontinence
bladder training
anti-muscarinics, eg oxybutynin, fenosteride
Stress incontinence
pelvic floor exercises
Overflow
removal of obstruction
Functional
improve facilities
regular urine voiding
absorbent padding. MANAGEMENT (cont)
7. The Pharmacy Guild of Australia NSW Branch Medications can be a common cause of incontinence
Alpha-blockers (eg prazosin)
Diuretics
Sedatives
Calcium channel blockers
Sympathomimetic decongestants (eg pseudoephedrine)
Anticholinergics (doxepin, hyoscine, ipratropium, benztropine, chlorpromazine, imipramine, amitriptyline)
MEDICATIONS THAT CAN CONTRIBUTE TO INCONTINENCE
8. The Pharmacy Guild of Australia NSW Branch Urgency incontinence due to increased activity of the detrusor smooth muscle may be worsened by
poor mobility, resulting in patients not reaching the toilet in time
by urinary tract infection.
For symptomatic control, use:
oxybutynin
URGE INCONTINENCE
9. The Pharmacy Guild of Australia NSW Branch DOSE:
Elderly, start with 2.5 mg at night and increase slowly if necessary. (AMH 2008)
5 mg orally, 2 or 3 times daily (decrease dose in the elderly or debilitated to 2.5 mg twice daily, maximum (eTG)
ADVERSE EFFECTS: cognitive dysfunction
confusion, hallucinations, anxiety, paranoia
OXYBUTYNIN(Ditropan)
10. The Pharmacy Guild of Australia NSW Branch DOSE
Adult, initially, 5 mg once daily; if necessary, increase dose to 10 mg once daily.
Do not exceed 5 mg daily in people with moderate hepatic impairment, creatinine clearance <30 ml/minute or taking potent CYP3A4 inhibitors (eg itraconazole, ketoconazole, ritonavir).
Counselling:
Swallow tablet whole; do not crush or chew
Adverse Effects: anticholinergic eg dry mouth, urinary retention, constipation SOLIFENACIN (Vesicare)
11. The Pharmacy Guild of Australia NSW Branch May respond to:
prazosin 0.5 mg orally, twice daily, increasing to 2 mg, twice daily, if tolerated
OR
amitriptyline 25 mg orally, at night, increasing to 100 mg daily, if tolerated
STRESS INCONTINENCE
12. The Pharmacy Guild of Australia NSW Branch Relax smooth muscle in the bladder neck and prostate, decreasing resistance to urinary flow.
DOSE:
0.5 mg twice daily for 37 days, then increase according to clinical response up to 2 mg twice daily
dose must be adjusted according to individual response
if treatment is interrupted for several days, restart and titrate dosage as if starting for the first time
stop if there is no benefit after 46 weeks of maximal treatment
Adverse Effects
first dose hypotension is common with the selective alpha-blockers; it is most serious in the elderly and in patients with fluid depletion or who are taking diuretics
PRAZOSIN (Minipress, Pressin)
13. The Pharmacy Guild of Australia NSW Branch Relax smooth muscle in the bladder neck and prostate, decreasing resistance to urinary flow.
DOSE: 400 mg once daily, in the morning.
Counselling: Swallow whole, with or after food
Adverse Effects: postural hypotension, dizziness, priapism,
TAMSULOSIN (Flomaxtra)
14. The Pharmacy Guild of Australia NSW Branch In terminal illness (eg due to complete sphincter dysfunction from spinal cord compression) can be managed with absorbent padding or an indwelling catheter.
Involvement of a urologist or continence clinical nurse consultant can be helpful
OTHER FORMS OF INCONTINENCE
15. The Pharmacy Guild of Australia NSW Branch BPH is the most common prostatic disorder; can cause urinary obstruction with symptoms such as hesitancy, dribbling after urination, nocturia, frequency and urgency and may culminate in urinary retention.
Neither the presence or absence of residual urine nor the size of the prostate are related to symptom severity, degree of obstruction or treatment outcome.
BENIGN PROSTATIC HYPERTROPHY
16. The Pharmacy Guild of Australia NSW Branch Exclude prostate cancer, UTI and renal failure.
Differentiate nocturia from polyuria (use a fluid balance diary). Heart failure may cause nocturia.
Consider using a scoring system to assess symptoms and monitor progress, eg International Prostate Symptom Score,
Mild symptoms, not causing undue discomfort, where surgery is not indicated, do not need active treatment, but watchful waiting with periodic reassessment.
BPH Before starting treatment
17. The Pharmacy Guild of Australia NSW Branch Reduces prostate size but appears to be effective only if the prostate is significantly enlarged (>40 cm3). Full clinical response may take 6 months or more. Generally well tolerated, although may cause sexual dysfunction. Less cost effective than selective alpha-blockers.
Drug Handling: Women who are or may become pregnant should not handle broken or crushed tablets without gloves (ADEC category X)
FINASTERIDE (PROSCAR)
18. The Pharmacy Guild of Australia NSW Branch Management of UTI in the elderly can be difficult. Sometimes over prescribing of antibiotics, with associated risk of adverse effects and development of resistance.
Key messages include:
Asymptomatic bacteriuria is common in the elderly.
Cloudy or malodorous urine in a patient without symptoms or signs does not require investigation or treatment.
Elderly patients with signs and symptoms of sepsis require urgent treatment. URINARY TRACT INFECTION
