Formulations and Routes of Administration for Eye Medicines:
For any condition, there are different routes of administration, which should be selected according to the condition and diagnosis. For dog eye conditions, there are three different routes of administration, i.e. topical, local or systemic.
Drugs are either administered through an oral route – as in cases of generalized illness such as fever. But for dog eye problems about 80% of medicines are administered through a local or topical route with administration directly into the eye.
Since dog eyes are delicate organs, local or topical eye medicines are specially specially formulated to work with the physiology of eye, i.e. in the form of eye drops, eye ointments, eye pads etc. These formulations contain an isotonic solution or buffering gel, combined with specific therapeutics such as antibiotics, corticosteroids, anti-inflammatory drugs, pain killers, pupil dilators/constrictors, anesthetics etc.
Dog Eye medicines usually are in the form of dog eye drops or dog eye ointments. The ointments last longer in the eye, so need to be applied with less frequency. The type of eye dog medicine varies based on the specific diagnosis and dog eye condition.

Types of Dog Eye Medicine:
Dog eye medicines are administered to treat specific conditions such as infections, to reduce inflammation, to eliminate or reduce pain and to regulate tear production. Similarly, other drugs may be used to reduce pressure over parts of the eye, to heal any injury and to manage abnormalities in focusing and dog eyesight.

administered locally (directly into the eye) in
the form of drops and ointments locally, and in the form of tablets and
if administered orally. Dog antibiotic eye drops usually contain one or
more antibacterial agents, administered according to the confirmatory

Different specific antibiotics such as oxytetracyclines, Bacitracin, neomycin, chloramphenical, erythromycin, gentamycin, polymyxin B, tobramycin etc are used individually or in combination for treating different species of bacteria that cause dog eye infections.
- Corticosteroids: Corticosteroids are used to reduce dog eye inflammatory response, thus symptoms of pain, redness, swelling, partial blindness and elevated temperature around dog eyes can be treated effectively. Different corticosteroids such as prednisolone and dextamethasome can be used in the eyes, but care is needed in terms of setting the dosage. Corticosteroids should never be used for dog eye ulceration or in viral or fungal infections before healing starts. Therefore, it is important to only use corticosteroids with a prescription and only after receiving a confirmatory diagnosis from a veterinarian.
- Atropine Sulfate: Atropine sulfate is
used to dilate or widen the eye
aperture. Eye medicine dog containing atropine as a base are used for
dilating dog eyes during injuries, for surgery and in order to treat
canine glaucoma. Eye dilation helps when operating during surgery and
when treating trauma. In canine glaucomas cases, dog eye pressure can
be reduced on the base of
Care should be taken when administering atropine. For example, it should not be administered to dogs with primary or severe canine glaucoma or those that are sensitive towards atropine. Similarly, once a dog is administered atropine in the eye, the dog should be kept in a dark environment and the eyes should not be exposed to bright light.
- Cyclosporines: These are ophthalmic preparations used to alter the immune response in canine eyes, i.e. reducing the chance of a severe immune response. It is usually prescribed in cases of Keratoconjunctivitis sicca or a dog dry eye condition.
- Synthetic Tears/Buffers: These are formulated as dog eye drops and ointments, used to replace or for ensuring adequate tear/lubricant supply over the eye surface. These are used either to support the eye during reduced tear flow over the surface of eye or for a dog dry eye condition. These special formulations are also used during surgery to keep the surface of the eye lubricated and moist. Buffered drops can also be used as a regular eye washing solution as well.
- Natural Remedies: Natural or herbal extracts are other ways to support dog eye health. Commercially available natural dog eye drops such as Eye Heal or dog eye area cleaning solutions such as i-Clenz can be effectively used to either treat minor eye conditions or to support specific therapeutics during the healing process. These remedies usually do not require a prescription and can be even more effective when used along with prescribed dog eye medicines.
