Effectiveness

How Tropicamide Affects PatientsTropicamide is a drug that helps with dilation of the pupil and relaxation of the eye muscles. It takes 10-15 minutes to start working, and its effects can last up to 24 hours. It can also raise the pressure inside the eye, but this is usually not associated with serious side effects. Tropicamide has been used to reduce symptoms of excessive saliva (sialorrhea) in people with Parkinson's Disease, and can be used to reduce tremulous jaw movements in rodent models.
How Tropicamide works in the bodyTropicamide is a drug that relaxes the muscles that control the pupil size and lens shape of the eye. It works by blocking muscarinic receptors in the eye, which are responsible for pupil constriction and accommodation. It also blocks salivary gland receptors, reducing saliva production. By blocking these receptors, tropicamide helps to reduce sialorrhea.

Tropicamide Reviews: What are patients saying about Tropicamide?

Tropicamide for Dilated Pupil
This is an excellent way to dilate your pupils with no other known side effects. It's both safe and effective, which makes it a great option overall.

Tropicamide for Dilated Pupil
These eye drops caused an intense burning sensation that made it difficult to open my eyes for some time. Even days later, my eyes were still sensitive to light. This has never happened before during my annual eye examinations, so I'm not sure if the medicine has changed or if it was just too strong this time around.

Tropicamide for Dilated Pupil
After using this medication, my eyes stayed dilated for six to eight hours. This was a problem because it made bright light intolerable. Additionally, my eyes were sensitive to light for two to three days following useage; it seems like the drug's effects and side-effects last too long.

Patient Q&A Section about tropicamide

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

How does tropicamide work in the eye?

"Tropicamide is a non-selective muscarinic antagonist that prevents the pupil from constricting by binding to muscarinic receptors, as well as prevents the eye from focusing by blocking the muscarinic receptors of the ciliary body."

Answered by AI

Is tropicamide eye drops safe?

"Tropicamide ophthalmic may cause blurred vision or make your eyes very sensitive to light. Be careful if driving or doing anything that requires clear vision. This effect may last up to 24 hours. Protect eyes from bright light while pupils are dilated."

Answered by AI

What type of drug is tropicamide?

"Tropicamide is a medication that is used to widen the pupil in preparation for certain eye examinations. It is an anticholinergic that works by relaxing the eye muscles."

Answered by AI

What is tropicamide used for?

"Tropicamide is used in order to increase the size of the pupil so that the doctor can clearly see the back of the eye. It is commonly used before examinations such as cycloplegic refraction and examination of the fundus of the eye. In some cases, tropicamide may also be used before and after eye surgery."
