Clinical effects and therapeutic usefulness of oxybutynin hydrochloride were evaluated in a long-term clinical trial on patients with unstable bladders and neurogenic bladders. Of the 46 patients entered into the trial, 37 were those diagnosed with an unstable bladder and 9 with a neurogenic bladder with overactive detrusor. In 37 of the cases (80%), the period of drug administration reached up to 12 weeks and in 16 cases (34%) the drugs were administered for more than 24 weeks. The average administration period was 165.9 days. The average total given dose was 1776.9 mg and average dose per day was 10.7 mg. Excellent and good responses were obtained in 76.3, 88.9 and 69.6% at 12 and 24 weeks after start of administration and at the time of discontinuing the drug, respectively. The cystometric changes at pre- and post-administration were evaluated on 23 cases and revealed a significant increase in volume at first sensation and maximum desire to void. Maximum resting intravesical pressure was significantly declined and uninhibited detrusor contractions were significantly suppressed. Side effects were noted in 11 of the 46 cases (23.9%), most of which were well tolerated by the patients. In 4 cases the drug had to be discontinued because of the side effects. Dry mouth was the most common side effect, occupying almost half of the incidents. No significant abnormality was noted on blood laboratory data, blood pressure or heart rate, following the drug administration. In one case slight increase in serum glutamic-oxalacetic transaminase and glutamic-pyruvic transaminase was encountered, but its relationship with the drug was obscure. The clinical usefulness of this drug (excellent and good) was 78.9, 88.9 and 69.6% at 12 and 24 weeks after start of administration, and at the time of drug discontinuation, respectively. The present long-term trial proved that oxybutynin hydrochloride is an exceedingly effective and safe agent for clinical management of unstable bladder and overactive neurogenic bladder.

The clinical trial development programme of mirtazapine (Org 3770), performed in Europe and the United States, demonstrated an outstanding safety profile of this compound. The evaluation of the safety was based on data from all patients who took at least one dose of study medication during studies comparing mirtazapine with placebo, amitriptyline or other active comparators. A general indication of mirtazapine's safety is the significantly lower percentage of patients (65%) who complained of any adverse clinical experiences compared with the placebo- (76%) or amitriptyline-treated group (87%). Moreover, drop-out rates due to adverse clinical experiences were significantly lower than in the amitriptyline-treatment group. Mirtazapine has virtually no anticholinergic, adrenergic or typical selective serotonin reuptake inhibitor (SSRI) side effects. The only significantly higher incidences versus placebo were seen in the adverse clinical effects of drowsiness (23% versus 14%), excessive sedation (19% versus 5%), dry mouth (25% versus 16%), increased appetite (11% versus 2%) and weight increase (10% versus 1%). These complaints were typically mild and transient in nature, and decreased over time despite increased doses of mirtazapine. In contrast, significantly higher incidences of headache (5% versus 10%) and weight decrease (2% versus 6%), symptoms commonly seen in depressed patients, were recorded in the placebo-treated patients. Also, typical SSRI adverse events, such as nausea, vomiting, diarrhoea and insomnia, and symptoms of sexual dysfunction were registered less frequently in mirtazapine-treated patients than in the placebo-treated patients. Approximately 10% of the mirtazapine-treated patients in the clinical trial programme were older than 65 years. The pattern of adverse clinical experiences seen in this group of patients is fully in line with that seen in the overall patient population. The analysis of vital sign indices, i.e. blood pressure and heart rate, showed that no changes occurred with mirtazapine treatment; this pattern was fully comparable to that seen with placebo. Furthermore, very low incidences of clinically relevant changes in laboratory indices, such as the liver enzymes alanine aminotransferase and aspartate aminotransferase or neutropenia, were recorded in each treatment group. Mirtazapine has a very low seizure-inducing potential: only one case was recorded in a patient with a history of seizures during previous treatment with clomipramine. The low seizure-inducing potential combined with a lack of cardiotoxic properties allows safety in an overdose of mirtazapine, even in elderly patients. The only symptom seen in the patients taking an overdose of mirtazapine alone or in combination with other drugs was excessive but transient somnolence, which resolved spontaneously within a few hours. In conclusion, the new antidepressant mirtazapine offers clinicians a unique combination of strong efficacy and good safety.

The safety and efficacy of one-year administration of propiverine hydrochloride (BUP-4 tablets) were assessed in facilities affiliated with the Department of Urology of Yokohama City University School of Medicine. Changes in subjective symptoms showed significant improvement in mean frequency of urination in the daytime from 10.3 +/- 4.0 times before administration to 7.1 +/- 2.9 times 1 year after the start of administration, in mean frequency of voiding at night from 4.2 +/- 1.7 times to 2.1 +/- 1.1 times and in mean incidence of urinary incontinence from 2.9 +/- 2.1 times to 0.7 +/- 1.0 times. The final degree of overall improvement rate was 82.0% (41/50 cases). Adverse effects were observed 26 times in 22 patients, the incidence being 15.6% (22/141 cases). They consisted of digestive symptoms in 9.9% (6 events of dry mouth, 4 of constipation, 2 of abdominal discomfort, 2 of diarrhea and 1 of gastritis), urinary tract symptoms in 3.5% (4 of dysuria and 1 of residual urine), abnormal laboratory findings in 1.4% (increase in glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase or lactate dehydrogenase levels) and others (1.4%). These results provide further evidence of the safety and efficacy of propiverine hydrochloride (BUP-4 tablets) even when administered for a long-term in the treatment of patients with pollakiuria and urinary incontinence.

A 16-year old girl presented with rapid onset of muscular weakness and a history of severe dysphagia, dysphonia and significant wasting. On examination, she was dystrophic (BMI 15.7) and had signs of myopathy. Laboratory findings confirmed myopathy (CPK 106.4 microkat/L (6384 IU/L), AST 2.86 microkat/L (171.6 IU/L), myoglobin 1582 microg/L). There was profound hypokalaemia (S-K 1.8 mmol/L) suggesting hypokalaemic paralysis. Diagnosis of distal renal tubular acidosis (dRTA) was based on combination of hyperchloremic metabolic acidosis, severe hypokalaemia, high urinary pH and positive value of urinary anion gap. There was evidence of other signs of renal tubular impairment (urinary beta-2-microglobulin 213 mg/L, glomerulotubular proteinuria 1.01g/24h). Autoimmune tests (rheumatoid factor, antinuclear antibodies, autoantibodies to Ro/SSA and La/SSB) together with symptoms of xerostomia with swallowing difficulties and atrophic glossitis suggested primary Sjogren's syndrome (SS) as the underlying cause of dRTA. The renal biopsy confirmed chronic tubulo-interstitial nephritis compatible with this diagnosis. Full recovery of muscle weakness and hypokalaemia and acidosis followed after potassium and alkali replacement therapy. Corticosteroids were administered with subsequent addition of cyclosporine A because of disease activity. In conclusion, primary SS is a rare diagnosis in childhood and adolescence and should be considered in patients presenting with hypokalaemic paralysis, as this might be due to dRTA, even in the absence of apparent sicca syndrome.
