Imprinted polymers are now being increasingly considered for active biomedical uses such as drug delivery. In this work, the use of molecularly imprinted polymers (MIPs) in designing new drug delivery devices was studied. Imprinted polymers were prepared from methacrylic acid (functional monomer), ethylene glycol dimethacrylate (cross-linker), and bromhexine (as a drug template) using bulk poly...

Bromhexine hydrochloride ion-selective electrodes (conventional type) based on bromhexinium tetraphenyl borate (I) and bromhexinium-phosphotungstate (II) were prepared. The electrodes exhibited mean slopes of calibration graphs of 59.4 mV and 59.8 mV per decade of bromhexine concentration at 25 C for electrode (I) and (II), respectively. Both electrodes could be used within the concentration ra...

Since its introduction to the market in 1963, bromhexine, an over-the-counter drug, has been investigated for its activity in animal models and in humans with diverse respiratory conditions. Bromhexine is a derivate of the Adhatoda vasica plant used in some countries for the treatment of various respiratory diseases. Bromhexine has been found to enhance the secretion of various mucus components...

Fungi is a well-known model used to study drug metabolism and its production in in vitro condition. We aim to screen the most efficient strain of Cunninghamella sp. among C. elegans, C. echinulata and C. blakesleeana for bromhexine metabolites production. We characterized the metabolites produced using various analytical tools and compared them with mammalian metabolites in Rat liver microsomes...

Existing treatment for Sjögren's syndrome is unsatisfactory, and uncontrolled observations have suggested that bromhexine may be effective. Twenty-nine patients with Sjögren's syndrome were therefore assigned to two randomised double-blind crossover trials with bromhexine and placebo, each comprising two two-week periods. In the first trial bromhexine 24 mg/day was given by mouth; in the second...

Background and aims. Xerostomia is one of the most common complications of head and neck radiotherapy. The aim of this study was to evaluate and compare the efficacy of pilocarpine and bromhexine in improving radiotherapy-induced xerostomia and its associated symptoms. Materials and methods. In this single-blind, randomized crossover study, pilocarpine and bromhexine tablets were used by twenty...

A simple reverse phase liquid chromatographic method has been developed and subsequently validated for simultaneous determination of salbutamol sulphate and bromhexine hydrochloride. The separation was carried out using a mobile phase consisting of acetonitrile, methanol and phosphate buffer, pH 4 in the ratio 60:20:20 v/v. The column used was SS Wakosil-II C-18 with a flow rate of 1 ml/min and...

Mucus was collected daily from open-ended pouches established surgically in three mini-pigs. After a five day control period bromhexine hydrochloride (BHCl) was administered to each pig at dose levels of 0.5, 1.0 and 2.0 mg.kg-1 twice daily for five days. Each study period was followed by a five day washout period, when mucus was collected but no drug given. The viscoelastic properties of each ...

Bromhexine was compared with a placebo in a double-blind clinical trial in bronchitic inpatients with mucoid sputum. Oral bromhexine 16 mg. thrice daily for 11 days compared with placebo resulted in a significant increase in sputum volume and significant decrease in sputum viscosity, and changed markedly the rheological characteristics of the sputum. There was, however, no improvement in ventil...
