Homatropine
Homatropine
Homatropine (pronounced as ho-MAT-ro-peen) is a type of drug used in ophthalmology and optometry to dilate the pupil and paralyze accommodation. It is a muscarinic antagonist that is often used as a cycloplegic and mydriatic agent.
Etymology
The term "Homatropine" is derived from the Greek words "homo" meaning "same" and "atropine", a type of alkaloid found in the deadly nightshade plant. The "same" refers to its similar effects to atropine.
Usage
Homatropine is used to dilate the pupil during an eye examination. It works by relaxing the muscles in your eyes to allow them to widen (dilate). This helps the doctor to examine the back of your eye, including the retina and vitreous humour. It is also used to relieve pain caused by swelling and inflammation of the eye.
Related Terms
- Atropine: A naturally occurring alkaloid extracted from the deadly nightshade plant, which has similar effects to homatropine.
- Cycloplegic: A drug that paralyzes the ciliary muscle of the eye, resulting in loss of accommodation.
- Mydriatic: A drug that dilates the pupil of the eye.
Side Effects
Like all medicines, homatropine can cause side effects, although not everybody gets them. Some common side effects include blurred vision, sensitivity to light, and eye irritation or redness. If you experience any severe or persistent side effects, you should contact your healthcare provider immediately.
Precautions
Before using homatropine, tell your doctor if you have any allergies or if you have any other eye conditions. It is also important to inform your doctor about all the medications you are currently taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
