Dapiprazole[edit]
Dapiprazole is a pharmaceutical drug that acts as an alpha-adrenergic antagonist. It is primarily used in ophthalmology to reverse the effects of mydriasis, which is the dilation of the pupil. This dilation is often induced by mydriatic agents during eye examinations to allow better visualization of the retina and other internal structures of the eye.
Mechanism of Action[edit]
Dapiprazole works by blocking the alpha-1 adrenergic receptors in the iris dilator muscle. This action counteracts the effects of mydriatic agents such as phenylephrine and tropicamide, which are commonly used to dilate the pupil. By inhibiting these receptors, dapiprazole causes the pupil to constrict, thereby reversing mydriasis.
Clinical Use[edit]
Dapiprazole is administered topically in the form of eye drops. It is used after diagnostic procedures that require pupil dilation, such as fundoscopy or slit lamp examination. The drug helps to restore normal pupil size more quickly, reducing the duration of light sensitivity and blurred vision that can result from prolonged mydriasis.
Side Effects[edit]
Common side effects of dapiprazole include:
- Eye irritation
- Conjunctival hyperemia (redness of the eye)
- Headache
- Brow ache
These side effects are generally mild and transient. However, patients with certain conditions, such as glaucoma, should use dapiprazole with caution.
Pharmacokinetics[edit]
Dapiprazole is absorbed through the cornea and acts locally in the eye. Its onset of action is typically within minutes, and the effects can last for several hours. The drug is metabolized locally in the eye tissues, and systemic absorption is minimal.
