Description

v A 2198352 1 - PHARMACEUTICAL COMPOSITIONS 1 1 The present invention
relates to a pharmaceutical composition containing as active ingredient the histamine H2 antaoonist ranitidine.
Ranitidine, [N-[2-[[[5-(dimethylamino)methyl-2-furanyllmethyllthiolethyllN'-methyl-2-nitro-1,1-ethenediamine, and its physiologically acceptable salts are described in British Patent Specification No. 1565966. In that specification there is reference to liquid formulations for oral and parenteral administrations and there is a description of an aqueous based formulation for intravenous use and another of an oral syrup. Both of these formulations contained sufficient hydrochloric acid to achieve a pH of 5.0 and 'the syrups also contained SorlDitol solution BPC and a fiavour as required.
British Patent Application No. GB 2142820A describes aaueous based formulations containinq ranitidine and/or one or more of its physiologically acceptable salts thereof having a pH within the ranQe 6.57.5. In that specification there is reference to liquid formulations for oral and parenterai administration and there are examples of aoueous formulations for intravenous and oral use. These formulations contain ranitidine hyrochloride and are buffered to a pH of approximately 7 and for intravenous administration the formulations also contain phenol or sodium chloride. For oral administration the formulation also contains hydroxyproDylmethyl cellulose as a viscosity enhancing agent, a preservative (parabens), a sweetening aaent and a flavour. These compositions have a significantly oreater shelf-iife over those in British Patent No. 1565966.
We have now surprisinqly found that the stability of ranitidine in aqueous based formulations and more particularly aqueous based formulations for oral administration may be substantially enhanced by the addition of ethanol to the formulation.
Thus the present invention provides a pharmaceutical composition which is an aqueous formulation of ranitidine and/or one or more physioloqically acceptable salts thereof also containing ethanol. The aqueous formulation is prepared using ingredients of a purity such that it is suitable for administration to patients and will in qeneral 2 contain at least one conventional pharmaceutical excipient in addition to the ethanol and ranitidine and/or physiolooically acceptable salts thereof.
The amount of ethanol present in the formulation is such that the resulting formulation has the enhanced stability. Preferably the amount of ethanol in the composition on a weiaht/volume basis of the complete formulation, is within the ranae 2.5'0 to 10'0, and more particularly is between 5 to 1000 w/v, more esoecially 7-8% w/v.
Preferred compositions according to the invention are those in which the pH of the aoueous formulation is within the ranoe 6.5 to 7.5, particularly 6.8 to 7.4 and more especially 7 to 7.3. The required pH of the formulation is preferably obtained by the use of suitaoie Duffer salts for example, potassium oinydroqen orthophosphate and disocium hydroqen orthophosph2te or citric acid and disodium hydroQen ortnophosphate.
A preferred emoodiment of the invention is an aQueous formulation for oral administration. Such a fo:-mulation may comprise ranitidine and/or one or more of its physiolocically acceptable salts dissolved in water, ethanol, a preservative and a viscosity enh2ncinQ 2qent. Preferably the reouired pH of the formulation is obtained by the use Of appropriate buffer salts. Optionally the composition may also contain other conventional excioients such as 2 sweetener, a fiavour and/or flavourina aids.
Examples of suitable preservatives include one or more alkyl hydroxybenzoates such as methyl, ethyl, propyl and/or butyl hydroxybenzoates.
Examples of suitable viscosity enhancino aaents include Xanthan gum; sorbitol; glycerol; sucrose; or a cellulose derivative such as carboxymethy1cellulose or a salt thereof or a CI-4 alkyi and/or a hydrOXYC2-4alkyl ether of cellulose such as methylcelluiose, ethylceliulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxyethylmethylcellulose and hyaroxypropylmethylcellulose.
Examples of suitable sweeteners include saccharin sodium, sodium cyclamate, soroitol and sucrose.
Examples of suitable flavouring agents include 'mint' flavours such as peppermint flavouring agents.
1 1 t i 11 - 3 The concentration of ranitidine in the oral formulation, expressed as free base, is conveniently within the range 20-400mg per 10mi, for example 20-200 mQ per 10mi, more particularly 150mq per 10ml dose.
The amount of ethanol in the formulation for oral administration, expressed as a percentage of the complete formulation on a weiqht/volume basis, is preferably within the r2noe 2.5 to 10'50, and more particularly between 5 to 10%, more especially 7-8,o.
The amount of viscosity enhancina aaent in the formulation will preferably be sufficient to give a solution with a viscosity in the ranqe of 10 to 100 centipoises.
The aoueous formulations for oral administration are conveniently prepared by mixinQ an aqueous solution of ranitidine and/or one or more of its physiologically acceotaole salts together with ethanol and the excipients, with aqueous solution_or dispersion of the viscosity enhancing agent.
The aqueous formulations accoroinq to the invention are preferably prepared using ranitidine in the form of its hydrochloride sait.
An illustrative example of a formulation accordino to the invention is as follows. In this example the relative proportions of ranitidine hydrochloride and the buffer salts are such that the formulation has a pH of approximately 7.
Ranitidine oral liquid formulation (150ma/10m1) expressed as free base % w/v Ranitidine hydrochloride 1.68 Ethanol 7.5 Potassium dihydrogen orthophosphate 0.095 Disodium hydroqen orthophosphate anhydrous 0.350 Hydroxypropylmethylcellulose qs Preservative qs Sweetening agents qs Flavour qs Purified water BP to 100M1
