Triamcinolone is used to treat a number of different medical conditions, such as eczema , Lichen sclerosus , psoriasis , arthritis , allergies , ulcerative colitis , lupus , sympathetic ophthalmia , temporal arteritis , uveitis , ocular inflammation , Urushiol-induced contact dermatitis , aphthous ulcers (usually as triamcinolone acetonide ), visualization during vitrectomy and the prevention of asthma attacks. It will not treat an asthma attack once it has already begun. [2] [3] [4] It has also been used off-label for macular degeneration . [5]



When to worry:
Anaphylaxis is an emergency and must be seen immediately by a vet. Often the reaction occurs in the vet clinic (sometimes within seconds of vaccination) or soon after the animal has left the clinic, although it can take up to 24 hours to manifest (so you should keep a close eye on the animal at home). The vet will usually rush the dog straight out to a treatment room, where it will receive oxygen, IV fluids, anti-histamines, adrenaline, anti-inflammatories and sometimes other drugs to aid in the treating of low blood pressure.



QNASL Nasal Aerosol is a pressurized, nonaqueous solution in a metered-dose aerosol device intended ONLY for intranasal use. It contains a solution of beclomethasone dipropionate in propellant HFA-134a (1,1,1,2-tetrafluoroethane) and dehydrated ethanol. QNASL 40 mcg Nasal Aerosol delivers 40 mcg of beclomethasone dipropionate from the nasal actuator and 50 mcg from the valve. QNASL 80 mcg Nasal Aerosol delivers 80 mcg of beclomethasone dipropionate from the nasal actuator and 100 mcg from the valve. Each strength delivers 59 mg of solution from the valve with each actuation. Each canister of QNASL 40 mcg or 80 mcg Nasal Aerosol, contains  g of drug and excipients and each provides 120 actuations after priming. Additionally, QNASL 40 mcg Nasal Aerosol contains g of drug and excipients and provides 60 actuations after priming.

As a glucocorticoid , the lipophilic structure of prednisolone allows for easy passage through the cell membrane where it then binds to its respective glucocorticoid receptor (GCR) located in the cytoplasm. Upon binding, formation of the GC/GCR complex causes dissociation of chaperone proteins from the glucocorticoid receptor enabling the GC/GCR complex to translocate inside the nucleus. This process occurs within 20 minutes of binding. Once inside the nucleus, the homodimer GC/GCR complex binds to specific DNA binding-sites known as glucocorticoid response elements (GREs) resulting in gene expression or inhibition. Complex binding to positive GREs leads to synthesis of anti-inflammatory proteins while binding to negative GREs block the transcription of inflammatory genes. [28]
