OBJECTIVE: The study aimed to evaluate efficacy of tiotropium as add-on therapy on top of standard regimens for uncontrolled asthma, specifically in terms of FEV1, morning and evening PEF, reduction in exacerbations, rescue medication use, and quality of life improvement.
METHODS: A search was done for eligible trials after which validity screen and data extraction was performed. Results were presented as mean differences, standard errors, and 95% confidence intervals, and graphically as forest plots. Estimates were pooled using the random effects model with I2 and Chi2 tests used to assess heterogeneity. Adverse events were reported as dichotomous variables.
RESULTS: Four studies were included totaling 1617 participants. The tiotropium group had statistically significant improvement in FEV1 (95% Cl, 0.14 [0.09, 0.19], p<0.00001), morning (95% Cl, 20.03 [11.71, 28.35], p<0.00001) with trend towards benefit in reduction of rescue medications (95% Cl, 0.12 [-0.17,0.4],p=0.42) and quality of life improvements (95% Cl, 0.1 [-0.05,0.25], p=0.20). Homogeneity (I2= 0%, Chi2= 0.47-3.22) was found across studies.
CONCLUSION: Tiotropium is associated with significant improvement in pulmonary function among patients with uncontrolled asthma, with possible benefit in reduction of rescue medications and quality of life improvement.

BACKGROUNDCompound anisodine (CA) is a compound preparation made from hydrobromide anisodine and procaine hydrochloride. The former is an M-choline receptor blocker with the function of regulating the vegetative nervous system, improving microcirculation, and so on. The latter is an antioxidant with the activities of neuroprotection. This study aimed to investigate the potential neuroprotection of CA, which affects the degeneration of the retinal ganglion cells (RGCs) in an animal model with chronic ocular hypertension.

METHODSFemale C57BL/6J mice (n = 24) were divided randomly into four groups: normal control group without any treatment (Group A, n = 6); CA control group with feeding the CA solution (Group B, n = 6); microbeads (MBs) control group with injecting MB into the anterior chamber (Group C, n = 6); CA study group with MB injection and with feeding the CA solution (Group D, n = 6). Intraocular pressure (IOP) was measured every 3 days after MB injection. At the 21st day, neurons were retrograde-labeled by Fluoro-Gold (FG). Animals were sacrificed on the 27th day. Retinal flat mounts were stained immunohistologically by α2-III-tubulin. FG-retrograde-labeled RGCs, α2-III-tubulin-positive RGCs, and α2-III-tubulin-positive nerve fibers were quantified.

RESULTSMice of Groups C and D expressed the incidence of consistent IOP elevation, which is above the IOP level of Group A with the normal one. There is no significant difference in IOP between Groups A and B (P > 0.05). On the 27th day, there were distinct loss in stained RGCs and nerve fibers from Groups C and D compared with Group A (allP < 0.001). The quantity was significantly higher in Group D as compared to Group C (allP < 0.001) but lower than Group A (allP > 0.001). There was no significant difference in the quantity of RGCs and nerve fibers between Groups A and B (allP > 0.05).

CONCLUSIONSThese findings suggest that CA plays an importantly neuroprotective role on RGCs in a mouse model with chronic ocular hypertension.

BACKGROUNDA pharmacokinetic study in an Asian population showed that tiotropium 5 µg via Respimat leads to the same plasma levels compared to 18 µg via HandiHaler. The objective of the trial was to compare the efficacy and safety of longterm treatment (1 year) with tiotropium bromide (5 µg) via Respimat® with placebo in patients with chronic obstructive pulmonary disease (COPD).

METHODSA total of 3991 patients were randomized in this double-blind, placebo controlled, parallel group study, while in China 338 patients (309 males, 29 females) received either tiotropium bromide (n = 167) or placebo (n = 171). Tiotropium bromide solution or matching placebo was delivered via Respimat® at a dosage of 5 µg (2×2.5 µg/puff) once daily for 48 weeks. Co-primary endpoints were trough forced expiratory volume in one second (FEV1) and the time to first exacerbation.

RESULTSStatistically significant improvements in trough FEV1 and trough forced vital capacity (FVC) in the tiotropium group were achieved at weeks 4, 24, and 48 compared with those in the placebo group. A statistically significant difference (P = 0.0027) in favour of tiotropium was also observed for the time to first exacerbation. The total numbers of exacerbations during treatment were 90 and 128 in the tiotropium and placebo groups, respectively, with a rate ratio of 0.69 (P = 0.0164). The difference between the treatment groups in the adjusted mean changes from baseline of St. George Respiratory Questionnaire (SGRQ) total score was -3.9 (95% CI: -7.5, -0.2) and was of statistical significance (P = 0.0367). The incidences of serious adverse events (SAEs) in the tiotropium and placebo groups were 16.2% and 17.0%, respectively. Seven deaths occurred whilst patients were on treatment, four in the tiotropium group and three in the placebo group, all of which were assessed as non-related study drugs by the investigators.

CONCLUSIONSTiotropium significantly improved lung function and quality of life, delayed the time to first exacerbation, reduced the number of exacerbations. Overall, tiotropium was well tolerated.

The prevention of and the controlling of symptoms, reductions in the frequency of exacerbations, and disease severity are central to the pharmacologic therapy of chronic obstructive pulmonary disease (COPD). COPD patients are inclined to be older, have more comorbidities, and use polypharmacy as a result. Long-acting inhaled muscarinic antagonists (LAMAs) is a preferred treatment modality. However, the cardiovascular (CV) safety of anti-cholinergics, including LAMA, has been an issue. In contrast, the results of the UPLIFT trial and a pooled analysis of data from 30 trials of tiotropium illustrates the association of tiotropium with reductions in the risk of all cause mortality, CV mortality and CV events. And, the UPLIFT trial provides clues regarding the additive advantages of tiotropium in COPD patients who already are using long-acting inhaled beta2 agonists and inhaled corticosteroids. Following the contribution of tiotropium as a first LAMA, new LAMAs such as aclidinium and glycopyrrolate (NVA-237) seem to be emerging.

OBJECTIVETo evaluate the therapeutic effect of compound anisodine (CA) for patients with primary open angle glaucoma (POAG).

METHODSAccording to the modified Hodapp-Parrish-Anderson Visual Fields Grading System, 46 patients with moderate stage POAG were randomized to receive compound anisodine injection (CA group) or venoruton tablets (control group). Visual acuity (VA), IOP, fundus, visual fields (VF) and the blood flow of optic nerve were observed.

RESULTSThe mean of defect (MD) was decreased in CA group after treatment. The PSV and EDV of ophthalmic artery were remarkably improved in both groups, as well as the PSV, EDV and RI of retinal central artery. Compound anisodine was superior in improving hemodynamics of ophthalmic artery and retinal central artery to venoruton.

CONCLUSIONCompound anisodine can protect optic nerve of POAG through improving the visual function and blood supply of optic nerve.

OBJECTIVETo observe the therapeutic effect of tiotropium bromide powder inhalation on stable bronchiectasis.

METHODSTwenty-two patients with stable bronchiectasis received inhalation of totropium bromide powder at the daily dose of 18 microg, and on days 1 and 28, the patients were examined for forced expiratory volume in one second (FEVl), predicted value [FEVl(%)], forced expiratory volume (FEV), and FEVl/FVC. The symptom score and BODE index were also recorded.

RESULTSAfter 1 month of inhalation therapy, the FEV1% of the patients showed a moderate increase but the increment was not statistically significant (t=-1.875, P>0.05); the symptom score and BODE index decreased significantly after the therapy (t=7.091, P<0.001; t=2.982, P<0.05).

CONCLUSIONLong-term inhalation of tiotropium bromide powder can improve the clinical symptoms and BODE index and enhance the exercise tolerance and quality of life of the patients with bronchiectasis.

BACKGROUND: A combination of salmeterol and fluticasone propionate (SFC) and tiotropium bromide (TIO) is commonly prescribed for COPD patients but there is little data on their effectiveness, particularly in COPD patients with bronchial hyperresponsiveness. This study compared the spirometric improvement based on the change in FEV1, FEV1/FVC, and IC as well as the clinical outcomes of the therapeutic strategies with SFC and TIO versus the individual components in patients with severe COPD and bronchial hyperresponsiveness. METHODS: This study examined the spirometric data and clinical outcomes of 214 patients with COPD and hyperresponsiveness, who were divided into three groups according to the therapeutic regimen (TIO only, SFC only, and a triple therapy regimen). RESULTS: All regimen groups showed early improvement in the FEV1 and IC (at 3- and 6 months after treatment). However, long-term beneficial effects were observed only in the SFC group (at 24 months after treatment). However, these beneficial effects decreased after a 36-month follow up. In all spirometric results, the 12-, 24-, and 36-months data showed a similar degree of improvement in the three groups. The triple therapy group showed higher St. George's Respiratory Questionnaire scores and lower acute exacerbations and hospitalization. CONCLUSION: SFC can be a more important component in the pharmacological treatment of severe COPD patients with hyperresponsiveness than TIO, particularly in the spirometric and clinical outcomes.

BACKGROUND/AIMS: Cimetropium bromide has been used widely as a premedication for endoscopy; however, there are no subjective data pertaining to the effects of cimetropum bromide as a premedication. Thus, the current study was undertaken to compare the effects of cimetropum bromide with placebo as a premedication for esophagogastroduodenoscopy (EGD). METHODS: Two hundred ninety-nine consecutive outpatients who had undergone EGD were enrolled in this study. Thirty minutes before EGD, the patients were randomly given an intramuscular injection of cimetropium bromide (5 mg) or saline using a placebo-controlled, double-blind, randomized technique. Immediately after EGD, all the patients and endoscopists were requested to fill out the questionnaire form. RESULTS: One-hundred patients were injected with cimetropium bromide and 150 patients were injected with placebo. There was no statistically significant difference in the degree of residual gastric secretions, the peristaltic activity detected by endoscopists, and the comfort experienced by the patients in each study group. CONCLUSIONS: The intramuscular injection of cimetropium bromide (5 mg) as a premedication for EGD was not significantly superior to placebo, at least with respect to subjective parameters, in spite of its broad use.
