- the compositions may be in the form of tablets, lozenges, suppositories, or capsules. Usually the compositions are adapted for oral administration. However, they may be adapted for other modes of administration, for example sublingual or transdermal administration.
- the invention also provides a process for preparing a pharmaceutical composition comprising a thiazolidinedione, such as Compound (I), metformin hydrochloride and a pharmaceutically acceptable carrier, wherein the thiazolidinedione is formulated onto the surface of the metformin hydrochloride, which process comprises:
- Suitable carriers for the metformin hydrochloride comprises one or more components selected from: a binding agent, preferably PVP, a filler, a lubricants, a glidant, a disintegrant and a wetting agent.
- the carrier for the metformin hydrochloride is as indicated preferably PVP but optionally at least one additional binder, for example hydroxypropylmethyl cellulose (or HPMC) is also used.
- additional binder for example hydroxypropylmethyl cellulose (or HPMC)
- HPMC hydroxypropylmethyl cellulose
- the amount of PVP is the minimum required providing the required compressibility for metformin.
- the thiazolidinedione is dissolved or dispersed in a liquid and then applied to the surface of the metformin HCl.
- the liquid may be water or a suitable organic solvent, such as ethanol.
- a film-coating agent such as Opadry, is admixed with the thiazolidinedione solution or dispersion and this is applied to the surface of the metformin HCl.
- the thiazolidinedione solution or dispersion is applied to the metformin HCl and then the solution or dispersion of film coating agent is applied.
- the compositions are in unit dosage form.
- Unit dosage presentation forms for oral administration may as necessary contain conventional excipients such as binding agents, fillers, lubricants, glidants, disintegrants and wetting agents.
- binding agents include acacia, alginic acid, carboxymethylcellulose calcium, carboxymethylcellulose sodium, dextrates, dextrin, dextrose, ethylcellulose, gelatin, liquid glucose, guar gum, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methylcellulose, magnesium aluminium silicate, maltodextrin, methyl cellulose, polymethacrylates, polyvinylpyrrolidone, pregelatinised starch, sodium alginate, sorbitol, starch, syrup, and tragacanth.
- fillers include calcium carbonate, calcium phosphate, calcium sulphate, carboxymethylcellulose calcium, carboxymethylcellulose sodium, compressible sugar, confectioner's sugar, dextrates, dextrin, dextrose, dibasic calcium phosphate dihydrate, dibasic calcium phosphate, fructose, glyceryl palmitostearate, glycine, hydrogenated vegetable oil-type 1, kaolin, lactose, maize starch, magnesium carbonate, magnesium oxide, maltodextrin, mannitol, microcrystalline cellulose, polymethacrylates, potassium chloride, powdered cellulose, pregelatinised starch, sodium chloride, sorbitol, starch, sucrose, sugar spheres, talc, tribasic calcium phosphate, and xylitol.
- lubricants include calcium stearate, glyceryl monostearate, glyceryl palmitostearate, magnesium stearate, microcrystalline cellulose, sodium benzoate, sodium chloride, sodium lauryl sulphate, stearic acid, sodium stearyl umarate, talc, and zinc stearate.
- glidants examples include colloidal silicon dioxide, powdered cellulose, magnesium trisilicate, silicon dioxide, and talc.
- disintegrants examples include alginic acid, carboxymethylcellulose calcium, carboxymethylcellulose sodium, colloidal silicon dioxide, croscarmellose sodium, crospovidone, guar gum, magnesium aluminium silicate, microcrystalline cellulose, methyl cellulose, polyvinylpyrrolidone, polacrilin potassium, pregelatinised starch, sodium alginate, sodium lauryl sulphate, and sodium starch glycollate.
- An example of a pharmaceutically acceptable wetting agent is sodium lauryl sulphate.
- compositions may be prepared by conventional methods of blending, tabletting, or encapsulation. Repeated blending operations may be used to distribute the active agent throughout those compositions employing large quantities of fillers. Such operations are of course conventional in the art.
- the tablets may be coated according to methods well known in normal pharmaceutical practice.
- compositions are formulated according to conventional methods, such as those disclosed in standard reference texts, for example the British and US Pharmacopoeias, Remington's Pharmaceutical Sciences (Mack Publishing Co.), Martindale The Extra Pharmacopoeia (London, The Pharmaceutical Press) (for example see the 31st Edition page 341 and pages cited therein) and Harry's Cosmeticology (Leonard Hill Books).
- compositions for use in a method for the treatment of diabetes mellitus, preferably Type 2 diabetes, and conditions associated with diabetes mellitus.
- Compositions may, if desired, be in the form of a pack accompanied by written or printed instructions for use.
- Compound I is added to an Opadry coating suspension and applied to the surface of a preformed metformin tablet.
- the Opadry I barrier and sealing coat are of identical formulation and are prepared as 15% w/w solid suspension.
- the Opadry I plus Compound (I) suspension is prepared as a 15% w/w solid suspension with a 2:1 ratio of Opadry to Compound (I).
- Metformin HCl tablet (equivalent to 500mg metformin HCl)
- Metformin HCl tablet (equivalent to 500mg metformin HCl) 520 Opadry Barrier Coat ( 1 % of tablet core) 5.20 Opadry plus Compound (I) (equivalent to 4mg Compound (I)) 15.90 Opadry I Sealing Coat (2% of tablet core) 10.80
