Definitions
- the invention relates to a corticosteroid-containing pharmaceutical preparation intended for topical use.
- Corticosteroids constitute a large group of compounds with a pregnene or pregnadiene backbone and with versatile medical uses. In particular they are used topically as anti-inflammatory dermatological medicines.
- Examples of corticosteroids on the market include hydrocortisone, dexamethasone, betamethasone, methylprednisolone, prednisolone, prednisone, beclomethasone, fludrocortisone, triamsinolone, desonide, fluprednidene, clobetasone, alclomethasone, momethasone, desoxymethasone, fluosinonide, budesonide and fluosinolone .
- ester-form glucocorticoids such as betamethasonide propionate
- Carbomer i.e. carboxyvinyl polymer
- Hydrocortisone gels are not available on the market. Attempts to prepare a hydrocortisone gel by using conventional gellants such as Carbomer polymer have failed owing to the poor stability of hydrocortisone.
- a corticosteroid-containing pharmaceutical formulation according to the invention is characterized in that the formulation has been brought to gel form by means of a gellant, the gellant being hydroxyalkyl cellulose.
- the corticosteroid may be any pharmaceutically acceptable corticosteroid.
- the corticosteroid is hydrocortisone.
- the hydroxyalkyl cellulose used as the gellant is hydroxyethyl cellulose or hydroxypropyl cellulose, in particular hydroxyethyl cellulose.
- the solvent used is preferably a mixture of water and a lower alcohol, such as ethanol or propanol.
- a mixture of water and ethanol or of water and isopropanol is especially preferable .
- Glycerol or propylene glycol is preferably added to the formulation in order to prevent skin drying caused by the alcohol (ethanol).
- alcohol ethanol
- some oil component such as Cetiol SN (cetearyl- isononanoate)
- suitable perfumes and preservatives include methylparahydroxybenzoate, propyl- parahydroxybenzoate and benzyl alcohol.
- hydrocortisone-containing gel batches I, II, III and IV were prepared. Batches I and II were prepared on a laboratory scale (1000 g/batch) and batches III and IV were prepared on an industrial scale (150 kg/batch). The soft gels were packed into polyethylene tubes. The stability of the gels was monitored for 18 months (batch I), 12 months (batch II) and 3 months (batches III and IV).
- the gels were prepared as follows: HEC was added to a mixture of water and ethanol (containing only a portion of the ethanol) while stirring, and the mixture was allowed to gel. Thereafter the glycerol was added while stirring. The balance of the ethanol was added while stirring. Thereafter the active ingredient was added to the gel while stirring.
- the batches were stored at a relative humidity of 60 %.
- the temperature was 25 °C (batches I, III and IV) and respectively 20 °C (batch II).
- the amount of degradation products may be at maximum 5 %, the amount of hydrocortisone should be 9.0 - 11.0 mg/g, and the pH should be 5 - 8.5.
- hydrocortisone gel formulations A, B, C and D were prepared, in which the gellant used was carboxyvinyl polymer Carbomer 980 or Carbomer 940, or polymer Stabileze R QM, which is a copolymer of methylvinyl ether and maleic acid anhydride, cross- bridged with 1 , 9-decadiene .
- These gellants yield a very low pH value (the pH of a 1 % aqueous dispersion of Carbomer polymer is 2.5 - 3.0), and therefore sodium hydroxide was added to adjust the pH to the desired range.
- the auxiliary compositions and hydrocortisone concentrations of the preparations are shown in Table 1, which also shows the stabilities of the preparations .
- Table 1 shows that, already after three months of storage, a large quantity of degradation products of hydrocortisone had formed. After six months of storage the concentration of hydrocortisone degradation products in preparations A, B and D clearly exceeded the guideline values (guideline value at maximum 5 % ) , and the concentration of degradation products in preparation C was also very high (4 %).
