A pharmaceutical composition comprising tyrosine and a polymerised allergen is prepared by (a) polymerising an allergen, (b) mixing an aqueous solution of the allergen with a solution of tyrosine in a strong aqueous acid, (c) neutralising the mixture of solutions, thereby co-precipitating tyrosine and polymerised allergen, and (d) optionally, mixing the product with a physiologically acceptable carrier. |
