crastinum bromide eye drop is a topical anti-muscarinic drug used to treat the symptoms of uveitis and other inflammatory conditions of the eye.

It acts by blocking M3 receptors on the smooth muscle cells of the iris, thereby reducing their contraction in response to acetylcholine. This results in relaxation of the iris sphincter and outflow facility of the aqueous humor within the eye.

The primary active ingredient in crastinum bromide eye drops is 0.5% ophthalmic solution of crastinum bromide (1% ointment).

Other ingredients include sodium chloride, benzalkonium chloride, hydrochloric acid, and water for injection.

The recommended dose is two to four drops per hour, depending upon the severity of the condition. The maximum concentration should not exceed 2%. In general, the frequency of use decreases as the disease improves.

The duration of use depends on the underlying condition and the patient's response to treatment. It may be necessary to continue using crastinum bromide eye drops intermittently even after the underlying condition has been treated.

The most common side effects associated with crastinum bromide eye drops are blurred vision, dry eyes, and increased intraocular pressure. These side effects usually resolve over time without causing permanent damage. However, if the side effects persist or worsen, it is important to consult with a healthcare professional.

The potential risks associated with crastinum bromide eye drops include increased intraocular pressure, blurred vision, dry eyes, and skin irritation. These risks can be minimized by following the manufacturer's instructions for use and consulting with a healthcare professional before using crastinum bromide eye drops.
