During ophthalmic procedures, studies and operations, it is necessary to use such agents as eye drops. Tropicamide is a drug that dilates the pupil and temporarily immobilizes the apple. In addition, this drug is often used in complex treatment regimens for various inflammatory diseases.
Eye drops Tropicamide - composition and main properties
The active ingredient corresponds to the name of the drug, tropicamide. This substance is a blocker of m-cholinergic receptors and works like atropine. The change in the diameter of the pupil regulates the ciliary muscle. The droplets under consideration for a short time immobilizes it, which, accordingly, causes mydriasis - the dilatation of the pupil.
Auxiliary ingredients are hydrochloric acid, sodium chloride and benzalkonium, disodium salt and purified water for injection.
The essence of the action of Tropicamide lies in the paralyzing effect. After 7-10 minutes after instillation, the pupil dilates, the maximum of the midratic process is reached after 20 minutes. The drug lasts for 1-2 hours depending on the concentration of the drops.
Tropicamide eye drops are prescribed in such cases:
- examination of the fundus;
- definition of the refractive power of the eye (refraction);
- for cycloplegia and mydriasis in ophthalmologic diagnostics;
- elimination of fusion of the tissues of the eye and surrounding mucous membranes;
- in the complex therapy of inflammation.
The agent is injected into the lower conjunctival sac of each eye by 1-2 drops. Depending on the purpose of the study, 0.5 or 1% solution is used. To avoid negative side effects and absorption of Tropicamide into the blood, it is advisable to massage lacrimal sacs immediately after instillation for 2 minutes.
To stop inflammation and improve the patient's condition, the drug is used 5-6 times a day at the indicated dosage.
Do not use drops during glaucoma, as well as simultaneously with the installed contact lenses.

- violation of visual perception of reality (accommodation);
- attacks of increased intraocular pressure;
- photophobia (photophobia);
- tachycardia ;
- headache;
- burning and dry mouth ;

Is tropicamide a drug?
Drug dependent people often acquire the described drug to enhance the effect of the main substance used, most often heroin or poppy. The widespread opinion that this medicine in itself causes a state of intoxication, is mistaken. Even with intravenous administration of large doses of drops, the body does not experience any sensations, except for an easy retardation of reactions. Therefore, the release of Tropicamide from the pharmacy is free, without the prescription of an ophthalmologist.
Another myth about the drug: ingestion allows you to feel euphoria. In fact, the effect of the active ingredient does not appear due to the low concentration of this substance, as well as the neutralization of the agent by gastric juice.
