- the compounds of Formula I described in the present invention are a subset of those described in WO 01/60805.
- odour related adverse events were observed. These included abnormal smelling faeces, urine, sweat 0 and hair. We now propose that this adverse event was caused by degradation of the compounds in the acidic environment of the stomach to produce a degradation product containing a free thiol group. We further believe that this breakdown is less likely to occur in the less acidic intestinal environment.
- enteric polymer is a term of the art referring to a polymer which is preferentially soluble in the less acid environment of the intestine relative to the more acid environment of the stomach.
- the instant invention provides a pharmaceutical formulation 0 comprising a core which includes a pharmaceutically active ingredient which is a compound of formula (I):

- Lactose monohydrate, microcrystalline cellulose, the active ingredient, the hydroxypropyl methyl cellulose and half of the croscarmellose sodium were screened into a 10 Litre Fielder high-shear blender (any suitable high shear blender could be used) and blended for 5 minutes at 300 rpm with the chopper off. The mixture was then granulated by the addition of about 750 ml water whilst continuing to blend. The granules were dried in a Glatt 3/5 fluid bed drier , screened by Comil into a Pharmatec 5 Litre bin blender and then blended with any lactose anhydrous given in the formula plus the remainder of the croscarmellose sodium over 5 minutes at 20 rpm.
- Magnesium stearate was screened into the blender and the mixing process continued for a further 1 minute at 10 rpm.
- the lubricated mix was compressed using a Riva Piccola rotary tablet press fitted with 9.5mm round normal concave punches (any suitable tablet press could be used).
- the sealcoat, and subsequently the enteric coat are applied by spraying of an aqueous suspension of the coat ingredients in a Manesty 10 coater using parameters for the coating process as recommended by the manufacturers of the coating polymers (again, any suitable coater could be used).
- Eudragit® L30 D-55 The quantity listed represents the 30% solids content in Eudragit® L30 D-55. It is calculated to give approximately 10 mg/cm 2 dry polymer per t o o surface area.
- Compounds of Formula (I) hydrolyse, particularly under conditions where pH corresponds to that typically prevailing in the human stomach, to form a thiol and a uracil in a 1:1 stoichiometric ratio.
- the thiol has a smell characteristic of compounds of its class, the intensity of the smell increasing with the concentration of the thiol.
- concentration of the uracil is a surrogate marker for the intensity of the smell.
- the uracil produced by the active is N-[2-(diethylamino)ethyl]-2-(2,4-dioxo-2,3,4,5,6,7- hexahydro-lH-cyclopenta[c ]pyrimidin-l-yl)-N- ⁇ [4'-(trifluoromethyl)-4- biphenylyl]methyl ⁇ acetamide, as shown in Formula (II):
- the enteric coat will be destroyed under conditions whose pH correspond to that prevailing in the human intestine.
- active equivalent to 80mg was immersed in 250mL simulated intestinal fluid (corresponding to the fasted state in humans) held at 37°C and stirred at 50rpm in a USP2 dissolution apparatus. This is chemically equivalent to a tablet whose enteric coat has been destroyed and whose core has subsequently disintegrated.
- QL the concentration below which formula (II) cannot be precisely quantified (which was estimated experimentally to be 1.71 ng/mL).
- Comparative Example 7 Results of a study comparing adverse events seen with enterically coated tablets of hydrochloride salt and placebo.
- l-(N-(2-(Diethylamino)ethyl)-N-(4-(4-trifluoromethylphenyl)benzyl)aminocarbonylmethyl)- 2-(4-fluorobenzyl)thio-5,6-trimethylenepyrimidin-4-one (called “active” in this example) is an amine, and therefore, in humans, is less soluble at typical intestinal pH (pH 6.8) than at typical stomach pH (1 to 4). Therefore its availability is likely to be diminished by the application of an enteric coat to the tablet which will delay core dissolution until the tablet reaches the intestine.
- Alternative formulations have been developed, in which the particle size of active is reduced by milling.
- enteric-coated active tablets An in vitro three-armed study was performed on enteric-coated active tablets to test the hypothesis that particle size reduction increases dissolution rate.
- an enteric- coated tablet containing active equivalent to 80 mg was placed in 500 rnL simulated intestinal fluid (SIF, corresponding to the fasted state in humans, pH 6.8) held at 37°C and stirred at 100 rpm in a USP2 dissolution apparatus.
- SIF simulated intestinal fluid
- the concentration of active in solution is monitored by measuring its absorbance at a wavelength corresponding to its spectral maximum and using Beer's Law to calculate the fraction released.
- the data obtained (shown in Table 9 and Fig.l) confirm the aforementioned hypothesis:
