- X is H, Cl or F
- Y is H or Cl
- R is benzyl or thienyl, each optionally substituted with Cl or F; said tablet being coated with a coating containing a sufficient amount of yellow dye #6, red dye #40, red dye #3, yellow lake #6, red lake #40 and red lake #3 to inhibit photodecomposition of said pharmaceutically active ingredient.
- this invention comprises a coated tablet wherein said coating contains yellow dye #6 in sufficient amount to inhibit photodecomposition of said pharmaceutically active ingredient.
- this invention comprises a capsule comprising a pharmaceutically active ingredient selected from a compound of the formula
- X is H, Cl or F
- Y is H or Cl
- R is benzyl or thienyl, each optionally substituted with Cl or F; said capsule shell containing a sufficient amount of yellow dye #6, red dye #40, red dye #3, yellow lake #6, red lake #40 and red lake #3 to inhibit photodecomposition of said pharmaceutically active ingredient.
- Light absorbing means means materials which block all or most wave lengths of light such as opaque glass or metals; or materials which absorb light with wave lengths of less than 600 nm such as ultra violet stabilizers or dyes.
- the light absorbing means may be used in packaging materials such as blister packages, sachets or bottles.
- Chemical light absorbing means such as ultraviolet stabilizers may be incorporated in packaging material including blister packages, sachets or bottles or are preferably incorporated in capsule shells or tablet coatings. Chemical light absorbing means may also be mixed directly with the active ingredient prior to tableting or placing in a capsule shell.
- the compounds protected by this invention are acidic and form base salts. All such base salts are within the scope of this invention and can be formed as taught by these patents.
- Such suitable salts include both the organic and inorganic types and include, but are not limited to, the salts formed with ammonia, organic amines, alkali metal hydroxides, alkali metal carbonates, alkali metal bicarbonates, alkali metal hydrides, alkali metal alkoxides, alkaline earth metal hydroxides, alkaline earth metal carbonates, alkaline earth metal hydrides and alkaline earth metal alkoxides.
- bases which form such base salts include ammonia, primary amines, such as n-propylamine, n-butyiamine, aniline, cyclohexylamine, benzylamine, p-toluidine, ethanolamine and glucamine; secondary amines, such as diethylamine, diethanolamine, N-methylglucamine, N-methylaniline, morpholine, pyrroiidine and piperidine; tertiary amines, such as triethylamine, triethanolamine, N,N-dimethyianiline, N-ethylpiperidine and N-methyimorpholine; hydroxides, such as sodium hydroxide; alkoxides such as sodium ethoxide and potassium methoxide; hydrides such as calcium hydride and sodium hydride; and carbonates such as potassium carbonate and sodium carbonate.
- primary amines such as n-propylamine, n-butyiamine, ani
- Preferred salts are those of sodium, potassium, ammonium, ethanolamine, diethanolamine and triethanolamine. Particularly preferred are the sodium salts.
- the compounds to which this invention is applicable include soivates such as the hemihydrates and monohydrates of the compounds hereinabove described.
- Red and yellow dyes have been found effective in preventing contact of light and the associated light-induced degradation of 3-substituted oxindole-1-carboxamides.
- Preferred dyes are FD&C red #40, FD&C red #3 and FD&C yellow #6. Yellow #6 is especially preferred.
- the dyes are effective in preventing light-induced degradation of 3-substituted-oxindoie-1-carboxamides when mixed with the oxindole, applied to a preformed tablet in a coating, or in a gelatin capsule containing the oxindole.
- the preferred method is the coating of tablets.
- Film coating of pharmaceutical tablets is well known in the art and is described, for example, in United States Patents 4,828,841 ; 3,981 ,948; and 3,802,896 which are hereby incorporated by reference.
- Film coating materials such as white Opadry, Opadry II, Surelease, Aquacoat and Eudragit which are suitable for formulation with the selected dye are commercially available from Colorcon, West Point, PA; FMC Corp., Philadelphia, PA; Rohm Pharma, We ' iterstadt, Germany respectively.
- Dyes may also be formulated into gelatin capsules which are then filled with the oxindole.
- the technology for preparing capsules is well known to those of ordinary skill in this art. Capsules incorporating selected dyes are available commercially from
- 3,784,684 describes the incorporation of opacifers and dyes in gelatine capsule shells.
- the amount of dye in the coating or capsule shell is not critical except that sufficient dye must be incorporated to absorb any incident light. We have found that 1.2-2.8 mgAablet of yellow #6 prevented decomposition while in capsule shells 0.28 to 0.5 mg/capsule afforded light stability.
- a typical formulation of the coated tablets of this invention may be prepared as follows:
- LC assay results for these lots are summarized in the table below. All samples were analyzed in triplicate. Assay values for the uncoated tablets were close to the intended 100 mg/g. Levels of thiophene-2-carboxylic acid, 6-chloro-1H- quinazoline-2,4-dione, thiophene-2-carboxylic acid 1-carbamoyl-5-chloro-2-oxo-2,3- dihydro 1 H-indol-3-yl ester, 6-chloro-2-hydroxy-quinazoline-4-carboxylic acid and unknown #3 for the uncoated tablets increased significantly in the light cabinet (compared to 5°C control). No significant degradation was observed for the tablet cores stored at 5°C, 30°C or 50°C.
- the above ingredients were mixed and a portion roller compacted, then milled and reblended with the remaining ingredients, lubricated and encapsulated in gelatin capsules obtained from Capsugel, a division of Warner-Lambert Company.
- a preferred lubricant is sodium laurel sulfate.
- the capsules contained FD&C yellow dye 0.2651 % of total dry weight in the capsule body and 0.1768% in the cap.
