Preparations
Cromoglicic acid is available in multiple forms:
- as a nasal spray (Rynacrom(UK), Nasalcrom, Prevalin (Netherlands)) to treat allergic rhinitis.
- in a nebulizer solution for aerosol administration to treat asthma.
- as an inhaler (Intal) for preventive management of asthma. The maker of Intal, King Pharmaceuticals, has discontinued manufacturing the inhaled form, cromolyn sodium inhalation aerosol, due to issues involving CFC-free propellant. As stocks are depleted, this inhaler preparation will no longer be available to patients. In the EU it is manufactured without CFCs by Sanofi-Aventis, although it must be imported from Canada for USA residents.
- as eye drops (Opticrom and Optrex Allergy (UK), Crolom) for allergic conjunctivitis
- in an oral form (Gastrocrom) to treat mastocytosis, dermatographic urticaria and ulcerative colitis. Another oral product, Intercron (sodium cromoglicate in distilled water, from Zambon France), is used for food allergies.

Famous quotes containing the word preparations:
“The most evident difference between man and animals is this: the beast, in as much as it is largely motivated by the senses and with little perception of the past or future, lives only for the present. But man, because he is endowed with reason by which he is able to perceive relationships, sees the causes of things, understands the reciprocal nature of cause and effect, makes analogies, easily surveys the whole course of his life, and makes the necessary preparations for its conduct.”
—Marcus Tullius Cicero (106–43 B.C.)
“In all the important preparations of the mind she was complete; being prepared for matrimony by an hatred of home, restraint, and tranquillity; by the misery of disappointed affection, and contempt of the man she was to marry. The rest might wait. The preparations of new carriages and furniture might wait for London and the spring, when her own taste could have fairer play.”
—Jane Austen (1775–1817)
“At the ramparts on the cliff near the old Parliament House I counted twenty-four thirty-two-pounders in a row, pointed over the harbor, with their balls piled pyramid-wise between them,—there are said to be in all about one hundred and eighty guns mounted at Quebec,—all which were faithfully kept dusted by officials, in accordance with the motto, “In time of peace prepare for war”; but I saw no preparations for peace: she was plainly an uninvited guest.”
—Henry David Thoreau (1817–1862)
