Definitions
- This invention relates to a drug combination, its composition and its use in therapy, particularly in the therapy of cough.
- Cough is a protective reflex. Persistent cough can be distressing. Over- the-counter remedies are available but their effectiveness is doubtful.
- W098/42322 discloses the use of theobromine for the treatment of cough, to be given orally.
- Antihistamines namely diphenhydramine have been to shown to have efficacy in the citric acid-induced cough model in healthy human volunteers (Packman et. al., Int J Clin Pharmacol Ther Toxicol, 1991 ). However, a recent review article, Bjornsdottir et al. 2007 Dec, 29(6): 577-83 reports that presumptions about efficacy of diphenhydramine against cough in humans are not univocally substantiated in literature. In other words, there is no strong evidence that antihistamines have any efficacy in cough.
- the invention is based at least in part on data showing a synergistic antitussive effect for theobromine combined with the antihistamine chlorpheniramine, in a citric acid-induced cough model. Given the recent literature suggesting that antihistamines have no efficacy in cough, it was therefore surprising to find that a combination of theobromine and chlorpheniramine has an improved antitussive effect, compared to theobromine alone.
- an agent comprises theobromine and an antihistamine , as a combined preparation for simultaneous, sequential or separate use in therapy.
- a pharmaceutical composition comprises theobromine and an antihistamine.
- Figure 1 shows the effect of theobromine, and of a combination of theobromine and chlorpheniramine, on citric acid-induced cough in guinea-pig.
- antihistamine means an agent that inhibits the action of histamine via histamine receptors. This term represents a well-defined class of drugs that is well known to the skilled person.
- the antihistamine is an H-i-receptor antihistamine. Any suitable form of the antihistamine agent may be chosen. These include salts, prodrugs and active metabolites.
- the treatment of cough means any therapy that reduces the number and/or the severity of cough. Preferably, it means a reduction in the number of coughs, i.e. a direct antitussive effect that reduces the body's urge to cough. Therefore, according to a preferred embodiment of the invention, an agent comprises theobromine and an antihistamine, for use as an antitussive pharmaceutical composition.
- An agent of the invention is useful as an antitussive in the control of cough. Preferably, it is used in the control of nonproductive cough.
- the antihistamine may be used in an amount that is already known for its use, although combination according to this invention means that a reduced dose may be effective.
- the dose of the antihistamine that is administered with the theobromine will of course depend on the usual factors, including its potency, but is preferably at least 0.1 , e.g. at least 5, and may be up to 50 mg/kg/day. Preferably, it is dosed in a range of 0.1 to 30 mg/kg/day.
- any suitable form of theobromine can be chosen. These include salts, prodrugs and active metabolites.
- Theobromine may also be in the form of cocoa or chocolate.
- Suitable dose ranges for theobromine are known in the art and will depend on the usual factors (age etc); although the synergistic effect of the combination means that the effective dose may be reduced.
- a combination according to the invention may be provided in a single formulation or in separate formulations, for combined, simultaneous or sequential administration.
- This antihistamine may be chosen from the following drugs: diphenhydramine, loratadine, desloratadine, alimemazine, dimenhydrinate, doxylamine, meclizine, quetiapine, fexofenadine, pheniramine, cetirizine, promethazine, clemastine, chlorpheniramine, dexchlorpheniramine, levocetirizine, hydroxyzine, alimemazine, acrivastine, cyproheptadine, astemizole, fexofenadine, loratadine, cetirizine, levocetirizine, brompheniramine, dextrobrompheniramine, promethazine, mizolastine and triprolidine.
- the antihistamine is chlorpheniramine.
- the compounds of the invention may be administered by any available route, such as via the oral, inhaled, intranasal, sublingual, intravenous, rectal and vaginal routes.
- the compounds of the invention are preferably as combinations to be administered orally, for example as tables, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules.
- Preferred pharmaceutical compositions of the invention are tablets and capsules. Liquid dispersions for oral administration may be syrups, emulsions and suspensions. More preferably, the pharmaceutical composition of the combination is a pressed tablet or capsule with conventional excipients, examples of which are given below.
- compositions intended for oral use may be prepared according to any method known to the art for the manufacture of pharmaceutical compositions, and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavouring agents, colouring agents and preserving agents in order to provide pharmaceutically elegant and palatable preparations.
- Tablets contain the combined active ingredients in admixture with non-toxic pharmaceutically acceptable excipients which are suitable for the manufacture of tablets.
- excipients may be, for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example corn starch or alginic acid; binding agents, for example starch gelatin, acacia, microcrystalline cellulose or polyvinyl pyrrolidone; and lubricating agents, for example magnesium stearate, stearic acid or talc.
- the tablets may be uncoated or they may be coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period.
- a time delay material such as glyceryl monostearate or glyceryl distearate may be employed.
- Aqueous suspensions contain the combined active materials in admixture with excipients suitable for the manufacture of aqueous suspensions.
- excipients are suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinyl pyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally occurring phosphatide, for example lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long-chain aliphatic alcohols, for example heptadecaethyleneoxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids, for example polyoxyethylene sorbitan monooleate.
- suspending agents for example sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinyl pyrrolidone, gum tragacanth and gum
- the aqueous suspensions may also contain one or more preservatives, for example ethyl or n-propyl p- hydroxybenzoate, one or more colouring agents, one or more flavouring agents, and one or more sweetening agents, such as sucrose or saccharin.
- preservatives for example ethyl or n-propyl p- hydroxybenzoate
- colouring agents for example ethyl or n-propyl p- hydroxybenzoate
- flavouring agents such as sucrose or saccharin.
- sweetening agents such as sucrose or saccharin.
- Oily suspensions may be formulated by suspending the active ingredient in a vegetable oil, for example arachis oil, olive oil, sesame oil or coconut oil, polyoxyethylene hydrogenated castor oil, fatty acids such as oleic acid, or in a mineral oil such as liquid paraffin or in other surfactants or detergents.
- the oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol.
- Sweetening agents, such as those set forth above, and flavouring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an antioxidant such as ascorbic acid.
- Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the combined active ingredients in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable sweetening, flavouring and colouring agents may also be present.
- the combined pharmaceutical compositions of the invention may also be in the form of oil-in-water emulsions.
- the oily phase may be a vegetable oil, for example olive oil or arachis oil, or a mineral oil, for example liquid paraffin, or mixtures of these.
- Suitable emulsifying agents may be naturally occurring gums, for example gum acacia or gum tragacanth, naturally occurring phosphatides, for example soya bean, lecithin, and esters or partial esters derived from fatty acids and hexitol anhydrides, for example sorbitan monooleate and condensation products of the said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate.
