What class of drug is Dipivefrin?

What class of drug is Dipivefrin?

Dipivefrin is a member of a class of drugs known as prodrugs. Prodrugs are usually not active in themselves and require biotransformation to the parent compound before therapeutic activity is seen.

What are Miotic drugs used for?

Miotics (drugs that cause the pupil to contract) improve the outflow of aqueous as part of the treatment of glaucoma and reduce the risk of a posteriorly luxated lens entering the anterior chamber.

How does Dipivefrin reduce intraocular pressure?

The IOP reduction with dipivefrin is comparable with that of epinephrine. The liberated epinephrine exerts its action by decreasing aqueous production and by enhancing outflow facility. The onset of action with dipivefrin occurs about 30 minutes after treatment, with maximum effect seen at about one hour.

Is Dipivefrin a prodrug?

Dipivefrin is a prodrug of epinephrine which is hydrolyzed to epinephrine after absorption into the eye.

Is Dipivefrin a cholinergic?

PROPINE® (dipivefrin) does not produce miosis or accommodative spasm which cholinergic agents are known to produce.

What are Cycloplegic drugs?

Cycloplegic drugs are generally muscarinic receptor blockers. These include atropine, cyclopentolate, homatropine, scopolamine and tropicamide. They are indicated for use in cycloplegic refraction (to paralyze the ciliary muscle in order to determine the true refractive error of the eye) and the treatment of uveitis.

What are miotic drugs examples?

Miotics, Direct-Acting

  • acetylcholine.
  • Akarpine.
  • carbachol.
  • IsoptoCarpine.
  • Miochol E.
  • Miostat.
  • pilocarpine ophthalmic.
  • Pilopine HS.

What is the best eye drop for glaucoma?

What types of eye drops can help glaucoma?

  • Prostaglandins, like Xalatan (latanoprost), Travatan Z (travoprost), Zioptan (tafluprost), and Lumigan (bimatoprost)
  • Rho kinase inhibitor, like Rhopressa (netarsudil)
  • Nitric oxides, like Vyzulta (latanoprostene bunod)

How does Dipivefrine increase trabecular outflow?

Pharmacology. Dipivefrine penetrates the cornea and is then hydrolysed to epinephrine by esterase enzymes. It increases outflow of the aqueous humour and also reduces its formation (mediated by its action on α1 and α2 receptors), thus reducing pressure inside the eye.

Where is adrenaline Synthesised?

adrenal medulla
Adrenaline is synthesized in the chromaffin cells of the adrenal medulla of the adrenal gland and a small number of neurons in the medulla oblongata in the brain through a metabolic pathway that converts the amino acids phenylalanine and tyrosine into a series of metabolic intermediates and, ultimately, adrenaline.

How do Cycloplegic drugs work?

Cycloplegics block the action of acetylcholine, a stimulatory neurotransmitter of the autonomic nervous system. So, they are known as anticholinergic or antimuscarinic drugs. 1 In the eye, acetylcholine receptors are located within the iris sphincter muscle as well as the ciliary body.

What is the usual dosage of dipivefrin hydrochloride ophthalmic solution?

The usual dosage of Dipivefrin Hydrochloride Ophthalmic Solution 0.1% is one drop in the eye (s) every 12 hours. When patients are being transferred to Dipivefrin from antiglaucoma agents other than epinephrine, on the first day continue the previous medication and add one drop of Dipivefrin to each eye every 12 hours.

What is ophthalmic dipivefrin?

Ophthalmic dipivefrin comes as a solution (liquid) to instill in the eye. Dipivefrin eye drops are usually applied every 12 hours.

What is Propine® (dipivefrin) used to treat?

PROPINE® (dipivefrin HCI ophthalmic solution, USP) is indicated as initial therapy for the control of intraocular pressure in chronic open-angle glaucoma. Patients responding inadequately to other antiglaucoma therapy may respond to addition of PROPINE® (dipivefrin) .

What class of drug is dipivefrin?

Clinical Pharmacology. Dipivefrin hydrochloride, is a member of a class of drugs known as prodrugs. Prodrugs are usually not active in themselves and require biotransformation to the parent compound before therapeutic activity is seen.
