Bimat ingredients include one active salt, i.e. Bimatoprost, and one inactive component, Benzalkonium Chloride. 

Bimatoprost is the active ingredient of Bimat eye drops. 

The Bimat-T eye drop is another variant of Bimat eye drops whose ingredients include Bimatoprost, Timolol maleate, and Benzalkonium chloride.

What do these terms (Bimatoprost, Timolol, Benzalkonium) mean?

Let’s find out! 

What is Bimatoprost?

Bimatoprost Ophthalmic is an active component in the list of Bimat ingredients.

It is used to treat Glaucoma and Ocular Hypertension. 

Glaucoma is a condition in which high pressure in the eye can lead to a gradual loss of vision.

Ocular Hypertension refers to increased pressure in the eye without any optic nerve damage or vision loss. 

Bimatoprost belongs to a medicinal class known as Prostaglandin Analogs.

It helps in lowering eye pressure by increasing the flow of natural eye fluids out of the eye.

In 2008, FDA also approved Bimatoprost to treat eyelash Hypotrichosis.

Eyelashes Hypotrichosis is a disorder characterized by an inadequate amount of eyelashes. 

One case study found that a 60-year-old woman who used Bimatoprost 0.03% solution on her eyebrows daily got great results.

Bimatoprost is an effective treatment for growing eyelashes and making them longer, thicker, and darker.

It has also been demonstrated to be beneficial to regrow eyebrows and addresses the Hypotrichosis of the eyebrows.

Working of Bimatoprost

Intraocular pressure is caused by the excessive buildup or high pressure of fluid (aqueous humour) in the eyes.

This aqueous fluid fills the space in the anterior chamber of the eyeball between the lens and cornea.

Bimatoprost functions by unclogging blocked ocular drainage channels.

Consequently, it promotes fluid drainage and decreases intraocular pressure.

This process relaxes and relieves strain on the optic nerve. This helps in treating different eye disorders. 

Bimatoprost as an eyelash serum functions by interacting with Prostaglandin receptors in the hair follicle and accelerating the transition from resting (telogen phase) to growing follicles (anagen phase).

It also improves the proportion and length of hair during the growth phase, resulting in eyelash growth.

What is Benzalkonium chloride?

Benzalkonium Chloride (BAC) is an inactive component in the list of Bimat ingredients.

It is used as a preservative in eyedrops and helps maintain Ophthalmic bottle sterility, which is important to prevent microbial contamination of the eye.

It is included in over 70% of Ophthalmic medications.

Several studies have concluded that BAC may also have altering effects on the bacterial flora of the conjunctiva.

Although BAC is a preservative with excellent antibacterial properties, harmful effects on the ocular surface have been demonstrated. 

Usual concentrations of BAC range from 0.004 to 0.01%. 

Higher concentrations may cause dry eye symptoms and trabecular meshwork degeneration. 

Bimat contains 0.005% of BAC, whereas Bimat-T contains 0.01% of BAC.

What is Timolol Maleate?

Timolol is one of the active Bimat ingredients present in Bimat-T eye drops (A variant of Bimat eye drops).

This medicine manages Glaucoma or other eye diseases that cause high pressure inside the eye (such as Ocular Hypertension).

Lowering high pressure inside the eye helps in preventing blindness. 

Working of Timolol Maleate

Timolol Maleate belongs to a medicinal class known as Beta-blockers.

It blocks the sympathetic nerve endings in the ciliary epithelium, which causes a fall in the production of aqueous humor. 

This decreases the amount of fluid within the eye.

Thus, lowering the pressure in the eye. 


The main Bimat ingredients are Bimatoprost and Aqua.

Bimatoprost is a scientifically backed medication that can be used for eye disorders and cosmetic purposes. 

Bimatoprost and Timolol are usually prescribed together when neither medicine alone is sufficient to treat the symptoms of Glaucoma or Ocular Hypertension (also known as Intraocular Hypertension).
