- an antitussive such as dextromethorphan hydrobromide
- a decongestant such as phenylephrine hydrochloride, pseudoephedrine hydrochloride or ⁇ ephedrine
- an antihistamine such as chlorpheniramine
- the composition can have an immediate release portion and a sustained release poition, such that the inhibition of mucus secretion, is therapeutically achieved for a period of approximately ⁇ 2 hours.
- the daily dose of guaifenesin can be 24O0mg.
- a method of treating an individual having a disease or condition characterized by increased mucin secretion with an effective amount of a composition which comprises guaifenesin as described in the first aspect of the present invention is provided.
- the disease of condition characterized by -increased mucin secretion infectious can be selected from inflammatory conditions of the airways.

- Fig, 6 is a graph showing the effect of guaifenesin on mucociliary clearance.
- Figs. 7a and 7b are graphs showing metabolic activity.
- Figs. 8a, 8 b and 8c are graphs showing mucus theology.
- Figs. 9a and 9b are graphs sho wing the vector sum of viscosity and elasticity against time and dose
- EpiAirway cultures normal human bronchial epithelial cells grown on Millipore Transwells, 1 or 4.2 cm 2 surface area. The cells were purchased from MatTek, and were cultured, at air-liquid interface for two (mucus synthesis and secretion) or three (mucociliary transport and mucus rheoiogy) weeks prior to use.
- a stock guaifenesin solution of 2 mg/mL in culture medium was prepared in the morning of each experiment, and kept cold until dilution into warmed medium to the target concentrations of 0,2, 2, 20 or 200 ⁇ g/mL.
- the medium in the basolateral compartment of each culture was replaced with the GGE-contammg medium, and the cultureswere returned to the 37°C, 5% CO 2 incubator for as the times indicated.
- the experiments were repeated three times on independent cultures.
- concentrations used in the in vitro experiments range from 0.2 ⁇ g/mL to 20 mg/mL and thus bracket the clinical doses used in humans.
- GUAIFENESIN solutions were prepared by dissolving in PBS .(phosphate buffered saline) immediately before treatment of the cells.
- MUC5AC mucins were quantified by BLISA using 45MI antibody (Lab vis ion, Fremont, CA).
- Confluent 1 cm * NHBE cells grown on an air/liquid interface were washed from the apical surface with 200 p.L PBS and incubated with fresh, complete growth medium added to the basal chamber. Cultures were incubated 24 hours to collect the apical fluid (pretreatment sample or PT) by adding 100 PBS to the apical, surface of the cultures.
- PBS was added to dilute the highly viscous, thin mucus layer on the surface. Because of the .small size of the insert, it was not feasible to collect a sufficient amount of mucus for both pharmacology and rheology without the addition of PBS.
- PT mucus samples
- cultures were divided into three groups (6 hr, 24 hr and 48 hr), 16 inserts per group, and treated with varying concentrations of guaifenesin (0, 0,2, 2, 20 ⁇ g/mL) for each time group, 4 inserts per each dose. Thus, a total of 48 inserts were used for this study ⁇ 4 inserts/dose x 4 doses/time point x 3 time points).
- the apical fluid was ' collected at 30 minutes following drug treatment front all the cultures to see whether guaifenesin affects the "secretion" of mucins.
- the apical, mucus sample was collected in two steps ⁇ first by adding 100 ⁇ . ⁇ PBS to the apical surface ( 1 st wash) and then by adding 100 ⁇ L ⁇ PBS containing 5 mM dilhiothreitol (DTT) (2" a wash). Samples from each wash were assayed for MUC5AC content and the sum of the two values (the 1 st and 2TM wash.) was expressed. -as the '"released MUC5AC" of the culture.
- Cultures (4.2 cm.') were exposed to basolaieral guaifenesin for 1 or 6 hr. The cultures were removed from the incubator and placed on. the stage of digital imaging microscopy system . Video data were collected for 10 seconds using a. 25x objective. The rate of movement of endogenous cell, debris -was analyzed on the video images using a transparent template overlay on the video images and a stopwatch to measure at least 5 particles on each culture, for a total of between 30 and 45 .measurements per condition.
- mucus was harvested from the apical surface of the cultures, without dilution.
- the rheologieal properties of apical mucus secretions (20 p.L) were measured using art ARI000 controlled stress rheometer (TA Instruments:, New Castle, DE) using a parallel plate ⁇ geometry.
- Rheologie data can also be presented using vectorial notation .as tangent ⁇ which is the ratio of viscosity to elasticity and G*, the vector sum of viscosity and elasticity (mechanical impedance).
- Fig. 3a the white boxes represent the amount of mucin associated with, the cell, whereas the black boxes represent the amount of mucin released during the given period of treatment. Therefore, the addition of the white box. and the black box represents the total amount of mucin produced during the given period.
- the total amounts ofMUC5 AC- were compared for statistical differences between control (no guaifenesin) and guaifenesin groups.
- guaifenesin appeared to increase the mobility of the cellular debris on the surface of cultures treated for 1 hr, but there was little evidence of a dose-response and in fact, only the effect of 2 ⁇ g/ l was statistically significant. However, at the 6 hr time point, there was a strong trend to a dose response and movement of the -surface material for all three concentrations tested was significantly faster than the control as illustrated -in.
- EpiAirway cultures were treated with the indicated concentrations of guaifenesin ⁇ b.r 1 or 6 his. Mucociliary clearance was assessed, by the rate of mo vement of endogenous debris on. the surfaces. *** indicates significantly different from- the control cultures- at the same time, p ⁇ 0.00.5.
- G* vector sum of viscosity and elasticity, at 1 rad-'s (Fig. 9a) arid 100 rad/sec (Fig. 9b), segregated by time as well as dose.
- Viscosity is the loss of energy from a rheoSogie probe or applied, stress and thus the resistance to flow.
- Elasticity storage modulus.
- the complex modulus, G* is also known as the mechanical impedance..
- G* measurement indicates -resistance lo deformation.
- Viscoelasiieity is a property of non-Newtonian fluids (gels). Dynaraie viseoelasticity measures •the strain response of mucus to an applied stress. Because mucus is subjected- to both low -stress (ciliary beat) and high stress (cough) conditions, we measure the strain developed in response to a dynamic stress.
