Compound (I) contains a chirai carbon atom, and hence can exist in up to two stereoisomeric forms, the term Compound (I) encompasses all of these isomeric forms whether as individual isomers or as mixtures of isomers, including racemates. ;The insulin sensitiser or the biguanide antihyperglycaemic agent of choice is prepared according to known methods, such methods are found or are referred to in standard reference texts, such as 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) or as described in the above mentioned publications. ;When used herein the term 'conditions associated with diabetes' includes those conditions associated with the pre-diabetic state, conditions associated with diabetes mellitus itself and complications associated with diabetes mellitus. ;When used herein the term 'conditions associated with the pre-diabetic state' includes conditions such as insulin resistance, including hereditary insulin resistance, impaired glucose tolerance and hyperinsulinaemia. ;'Conditions associated with diabetes mellitus itself include hyperglycaemia, insulin resistance, including acquired insulin resistance and obesity. Further conditions associated with diabetes mellitus itself include hypertension and cardiovascular disease, especially atherosclerosis and conditions associated with insulin resistance. Conditions associated with insulin resistance include polycystic ovarian syndrome and steroid induced insulin resistance and gestational diabetes. ;'Complications associated with diabetes mellitus' includes renal disease, especially renal disease associated with Type II diabetes, neuropathy and retinopathy. ;Renal diseases associated with Type II diabetes include nephropathy, glomerulonephritis, glomerular sclerosis, nephrotic syndrome, hypertensive nephrosclerosis and end stage renal disease. ;As used herein the term 'pharmaceutically acceptable' embraces both human and veterinary use: for example the term 'pharmaceutically acceptable' embraces a veterinarily acceptable compound. ;For the avoidance of doubt, when reference is made herein to scalar amounts, including mg amounts, of Compound (I) in a pharmaceutically acceptable form, the scalar amount referred to is made in respect of Compound (I) per se: For example 2 mg of Compound (I) in the form of the maleate salt is that amount of maleate salt which contains 2 mg of Compound (I). ;Diabetes mellitus is preferably Type II diabetes. ;The particularly beneficial effect on glycaemic control provided by the treatment of the invention is indicated to be a synergistic effect relative to the control expected for the sum of the effects of the individual active agents. ;Glycaemic control may be characterised using conventional methods, for example by measurement of a typically used index of glycaemic control such as fasting plasma glucose or glycosylated haemoglobin (Hb Ale). Such indices are determined using standard methodology, for example those described in: Tuescher A, 5 Richterich, P., Schweiz. med. Wschr. 101 (1971), 345 and 390 and Frank P., 'Monitoring the Diabetic Patent with Glycosolated Hemoglobin Measurements', ;Clinical Products 1988. ;In a preferred aspect, the dosage level of each of the active agents when used in accordance with the treatment of the invention will be less than would have been 10 required from a purely additive effect upon glycaemic control. ;There is also an indication that the treatment of the invention will effect an improvement, relative to the individual agents, in the levels of advanced glycosylation end products (AGEs), leptin and serum lipids including total cholesterol, HDL-cholesterol, LDL-cholesterol including improvements in the ratios thereof, in 15 particular an improvement in serum lipids including total cholesterol, HDL-cholesterol, LDL-cholesterol including improvements in the ratios thereof. ;In the method of the invention, the active medicaments are preferably administered in pharmaceutical composition form. As indicated above, such compositions can include both medicaments or one only of the medicaments. 20 Accordingly, in one aspect of the invention there is provided a pharmaceutical composition comprising an insulin sensitiser, such as Compound (I) especially 2 to 12 mg thereof, a biguanide antihyperglycaemic agent and a pharmaceutically acceptable carrier therefor. ;Such compositions may be prepared by admixing an insulin sensitiser, such 25 as Compound (I) especially 2 to 12 mg thereof, the biguanide antihyperglycaemic agent and a pharmaceutically acceptable carrier therefor. ;Usually the compositions are adapted for oral administration. However, they may be adapted for other modes of administration, for example parenteral administration, sublingual or transdermal administration. 30 The compositions may be in the form of tablets, capsules, powders, granules, ;lozenges, suppositories, reconstitutable powders, or liquid preparations, such as oral or sterile parenteral solutions or suspensions. ;In order to obtain consistency of administration it is preferred that a composition of the invention is in the form of a unit dose. ;35 Unit dose presentation forms for oral administration may be tablets and capsules and may contain conventional excipients such as binding agents, for example syrup, acacia, gelatin, sorbitol, tragacanth, or polyvinylpyrrolidone; fillers, for example lactose, sugar, maize-starch, calcium phosphate, sorbitol or glycine; ;-5- ;tabletting lubricants, for example magnesium stearate; disintegrants, for example starch, polyvinylpyrrolidone, sodium starch glycollate or microcrystalline cellulose; or pharmaceutically acceptable wetting agents such as sodium lauryl sulphate. ;The compositions are preferably in a unit dosage form in an amount 5 appropriate for the relevant daily dosage. ;Suitable unit dosages of the Compound of formula (I) comprise 1,2,3,4,5, 6, 7, 8,9,10,11 or 12 mg of Compound (I). ;The composition of the invention may be administered from 1 to 6 times a day, but most preferably 1 or 2 times per day. ;10 Particular dosages of Compound (I) are are 2mg/day, 4mg/day, including ;2mg twice per day, and 8 mg/day, including 4mg twice per day. ;Suitable unit dosages of the insulin sensitiser or the biguanide antihyperglycaemic agent, such as metformin, include the known doses for these compounds as described or referred to in reference texts such as the British and US 15 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) or the above mentioned publications. ;Suitable dosages of metformin include up to 3000mg per day, in unit doses of 20 500mg (for example two or three times per day) or 850mg (for example two times per day), one example of a dosage for metformin is 500mg once building to five times per day per day. ;Thus, one example of the method comprises the administration of 4 or 8mg of Compound (I) (at 2mg twice per day or 4mg twice per day respectively) and 25 lOOOmgor 25OOmg of metformin (at 500mg twice per day or 500mg five times per day respectively). ;The solid oral compositions may be prepared by conventional methods of blending, filling or tabletting. Repeated blending operations may be used to distribute the active agent throughout those compositions employing large quantities 30 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, in particular with an enteric coating. ;Oral liquid preparations may be in the form of, for example, emulsions, syrups, or elixirs, or may be presented as a dry product for reconstitution with water 35 or other suitable vehicle before use.

In preparing solutions the compound can be dissolved in water for injection and filter sterilized before filling into a suitable vial 10 or ampoule and sealing. Advantageously, adjuvants such as a local anaesthetic, a preservative and buffering agents can be dissolved in the vehicle. To enhance the stability, the composition can be frozen after filling into the vial and the water removed under vacuum. Parenteral suspensions are prepared in substantially the same manner, except that the Compound (I)s suspended in the vehicle instead of being 15 dissolved, and sterilization cannot be accomplished by filtration. The compound can be sterilized by exposure to ethylene oxide before suspending in the sterile vehicle. Advantageously, a surfactant or wetting agent is included in the composition to facilitate uniform distribution of the compound. ;Compositions may contain from 0.1% to 99% by weight, preferably from 20 10-60% by weight, of the active material, depending upon the method of administration. ;Compositions may, if desired, be in the form of a pack accompanied by written or printed instructions for use. ;The compositions are formulated according to conventional methods, such as 25 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). ;30 In a further aspect, the present invention also provides a pharmaceutical composition comprising an insulin sensitiser such as Compound (I) especially 2 to 12 mg thereof, a biguanide antihyperglycaemic agent and a pharmaceutically acceptable carrier therefor, for use as an active therapeutic substance. ;In particular, the present invention provides a pharmaceutical composition 35 comprising an insulin sensitiser such as Compound (I) especially 2 to 12 mg thereof, a biguanide antihyperglycaemic agent and a pharmaceutically acceptable carrier therefor, for use in the treatment of diabetes mellitus, especially Type II diabetes and conditions associated with diabetes mellitus. ;-7- ;A range of 2 to 4mg includes a range of 2.1 to 4,2.2 to 4, 2.3 to 4,2.4 to 4, 2.5 to 4,2.6 to 4,2.7 to 4,2.8 to 4,2.9 to 4 or 3 to 4mg. ;A range of 4 to 8mg includes a range of 4.1 to 8,4.2 to 8, 4.3 to 8,4.4 to 8, 4.5 to 8,4.6 to 8,4.7 to 8,4.8 to 8,4.9 to 8,5 to 8, 6 to 8 or 7 to 8mg. ;5 A range of 8 to 12 mg includes a range of 8.1 to 12, 8.2 to 12, 8.3 to 12,8.4 ;to 12, 8.5 to 12, 8.6 to 12,8.7 to 12,8.8 to 12, 8.9 to 12,9 to 12,10 to 12 or 11 to 12mg. ;No adverse toxicological effects have been established for the compositions or methods of the invention in the abovementioned dosage ranges. ;10 The following example illustrates the invention but does not limit it in any way. ;-8- ;Example ;This study evaluated the pharmacokinetics (PK) of Compound (I) and metformin (M) administered alone and in combination.
