In situ cross-linked matrix tablets for sustained salbutamol sulfate release - formulation development by statistical optimization.[Pubmed:25932903]

Polim Med. 2014 Oct-Dec;44(4):221-30.

BACKGROUND: The use of natural polymers in designing of matrix tablets for sustained-release drug delivery systems has received much attention. OBJECTIVES: The study involves the development and optimization of in situ cross-linked matrix tablets for sustained Salbutamol Sulfate release. MATERIAL AND METHODS: In situ cross-linked matrix tablets of Salbutamol Sulfate were prepared by direct compression and optimized by response surface methodology based on 32 factorial design. The influence on sodium alginate and a calcium salt (calcium carbonate) amounts in Salbutamol Sulfate matrix tablets on the properties like drug release and hardness of Salbutamol Sulfate sustained release matrix tablets were analyzed by response surface plots and corresponding contour plots. Drug contents, weight variations, hardness, and in vitro drug release with release kinetic analysis of these newly developed matrix tablets were also investigated. RESULTS: All these in situ cross-linked Salbutamol Sulfate matrix tablets showed satisfactory drug contents, weight variations, hardness and prolonged sustained release of Salbutamol Sulfate over 6 h. CONCLUSIONS: The developed Salbutamol Sulfate matrix tablets might be beneficial over the conventional tablets to decrease the dosing frequency and enhanced patient compliance.

Quantitative determination of salbutamol sulfate impurities using achiral supercritical fluid chromatography.[Pubmed:27915194]

J Pharm Biomed Anal. 2017 Feb 5;134:170-180.

In the last years, supercritical fluid chromatography has largely been acknowledged as a singular and performing technique in the field of separation sciences. Recent studies highlighted the interest of SFC for the quality control of pharmaceuticals, especially in the case of the determination of the active pharmaceutical ingredient (API). Nevertheless, quality control requires also the determination of impurities. The objectives of the present work were to (i) demonstrate the interest of SFC as a reference technique for the determination of impurities in Salbutamol Sulfate API and (ii) to propose an alternative to a reference HPLC method from the European Pharmacopeia (EP) involving ion-pairing reagent. Firstly, a screening was carried out to select the most adequate and selective stationary phase. Secondly, in the context of robust optimization strategy, the method was developed using design space methodology. The separation of Salbutamol Sulfate and related impurities was achieved in 7min, which is seven times faster than the LC-UV method proposed by European Pharmacopeia (total run time of 50min). Finally, full validation using accuracy profile approach was successfully achieved for the determination of impurities B, D, F and G in Salbutamol Sulfate raw material. The validated dosing range covered 50 to 150% of the targeted concentration (corresponding to 0.3% concentration level), LODs close to 0.5mug/mL were estimated. The SFC method proposed in this study could be presented as a suitable fast alternative to EP LC method for the quantitative determination of salbutamol impurities.

Effects of salbutamol aerosol combined with magnesium sulfate on T-lymphocyte subgroup and Th1/Th2 cytokines of pediatric asthma.[Pubmed:28123478]

Exp Ther Med. 2017 Jan;13(1):117-120.

The aim of the study was to analyze the effects of the intravenous infusion of salbutamol aerosol combined with magnesium sulfate in the treatment of pediatric asthma and the subsequent effects on the levels of T-lymphocyte subgroups and Th1/Th2 cytokines. A total of 86 patients with pediatric asthma, first diagnosed and treated at the Xuzhou Children's Hospital, were continuously selected and randomly divided into an observation group of 44 cases and control group of 42 cases. The patients in the control group were treated with budesonide atomization inhalation, while the children in the observation group were treated with intravenous infusion of salbutamol aerosol combined with magnesium sulfate. The therapeutic effects in the groups were compared. After treatment, the levels of serum CD3(+) and CD8(+) decreased when compared to before treatment; the levels of CD4(+) and CD4(+)/CD8(+) also increased, but the observation group had more significant improvement. Differences were statistically significant (P<0.05). After treatment, the levels of serum interleukin-2 (IL-2) and interferon-gamma (IFN-gamma) increased when compared to before, while levels of IL-4 and IL-6 decreased, and the observation group had more significant improvement. The differences were statistically significant (P<0.05). After treatment, the levels of VT, t-PTEF/t-E, MTIF/MTEF and TEF75/PTEF increased when compared to before; the observation group had more significant improvement. The differences were statistically significant (P<0.05). The effective rate and degree of treatment for the observation group were significantly higher than those of the control group and differences were statistically significant (P<0.05). The intravenous infusion of salbutamol aerosol combined with magnesium sulfate in the treatment of pediatric asthma can significantly improve therapeutic effects and lung functions, improve immune functions and relieve inflammatory reactions. Therefore, it indicates better clinical application and promotion value.

The efficacy of nebulized magnesium sulfate alone and in combination with salbutamol in acute asthma.[Pubmed:27354766]

Drug Des Devel Ther. 2016 Jun 9;10:1927-33.

OBJECTIVE: Evaluation of the efficacy of nebulized magnesium sulfate (MgSO4) alone and in combination with salbutamol in acute asthma. METHODS: A double-blind randomized controlled study was conducted in Chest and Emergency Departments. Thirty patients of acute attack of bronchial asthma were randomized into three groups: MgSO4 nebulization (group A), salbutamol nebulization (group B), and their combination (group C). All patients were monitored before and after nebulization (each 20 minutes) for peak expiratory flow rate (PEFR), respiratory rate (RR), heart rate (HR), blood pressure, pulsus paradoxus, oxygen saturation, clinical examination, and Fischl index. RESULTS: A highly significant improvement in PEFR, PEFR percentage, and Fischl index and significant decrease in RR and HR was observed in all groups. A similar improvement in PEFR was observed in group A and group B (P=0.389). The difference in peak expiratory flow (PEF) improvement was insignificant between group B and group C (P=0.101), while there was a significant difference between group A and group C (P=0.014) in favor of group C. CONCLUSION: Nebulized MgSO4 alone or combined with salbutamol has a clinically significant bronchodilator effect in acute asthma and leads to clinical improvement, increase in PEFR, reduction in HR, and reduction in RR. The response to nebulized MgSO4 alone (PEFR improvement 54+/-35.6 L/min, P=0.001) is comparable (P=0.389) to that of nebulized salbutamol (PEFR improvement 67.0+/-41.9 L/min, P=0.001) and is significantly less than (P=0.014) that of nebulized combination (PEFR improvement 92.0+/-26.9 L/min, P=0.000).

Salmeterol-induced desensitization, internalization and phosphorylation of the human beta2-adrenoceptor.[Pubmed:9517390]

Br J Pharmacol. 1998 Feb;123(4):701-11.

1. Partial agonists of the beta2-adrenoceptor which activate adenylyl cyclase are widely used as bronchodilators for the relief of bronchoconstriction accompanying many disease conditions, including bronchial asthma. The bronchodilator salmeterol has both a prolonged duration of action in bronchial tissue and the ability to reassert this activity following the temporary blockade of human beta2-adrenoceptors with antagonist. 2. We have compared the activation and desensitization of human beta2-adrenoceptor stimulation of adenylyl cyclase induced by salmeterol, adrenaline and salbutamol in a human lung epithelial line, BEAS-2B, expressing beta2-adrenoceptor levels of 40-70 fmol mg(-1), and in human embryonic kidney (HEK) 293 cell lines expressing 2-10 pmol mg(-1). The efficacy observed for the stimulation of adenylyl cyclase by salmeterol was only approximately 10% of that observed for adrenaline in BEAS-2B cells expressing low levels of beta2-adrenoceptor, but similar to adrenaline in HEK 293 cells expressing very high levels of receptors. Salmeterol pretreatment of these cells induced a rapid and stable activation of adenylyl cyclase activity which resisted extensive washing and beta2-adrenoceptor antagonist blockade, consistent with binding to a receptor exosite and/or to partitioning into membrane lipid. 3. The desensitization and internalization of beta2-adrenoceptors induced by the partial agonists salmeterol and salbutamol were considerably reduced relative to the action of adrenaline. Consistent with these observations, the initial rate of phosphorylation of the receptor induced by salmeterol and salbutamol was much reduced in comparison to adrenaline. 4. Our data suggest that the reduction in the rapid phase of desensitization of beta2-adrenoceptors after treatment with salmeterol or salbutamol is caused by a decrease in the rate of beta2-adrenoceptor kinase (betaARK) phosphorylation and internalization. In contrast, the rate of cyclic AMP-dependent protein kinase (PKA)-mediated phosphorylation by these partial agonists appears to be similar to adrenaline.

Function and regulation of the beta 3-adrenoceptor.[Pubmed:8979772]

Trends Pharmacol Sci. 1996 Oct;17(10):373-81.

The cloning, sequencing and expression in model systems of the previously unidentified beta 3-adrenoceptor recently led to an extensive functional characterization. Ligand binding and adenylate cyclase activation studies helped define a specific profile that is quite distinct from that of the beta 1- and beta 2-adrenoceptors, but strongly reminiscent of most of the 'atypical' beta-adrenoceptor-mediated responses reported in earlier pharmacological studies. More recently, a naturally occurring variation in the human beta 3-adrenoceptor has been correlated with hereditary obesity and with increased dynamic capacity to add on weight and develop non-insulin dependent diabetes in Western obese patients. Donny Strosberg and France Pietri-Rouxel describe how results now provide a consistent picture of an important role for the human beta 3-adrenoceptor in the regulation of lipid metabolism and as an obvious target for drugs to treat some forms of obesity and diabetes.
