Dipivefrine, or dipivefrin, also known as epinephrine pivalate and sold under the brand name Propine among others, is a sympathomimetic medication which is used in the treatment of open-angle glaucoma. [2] [3] It is available as a 0.1% ophthalmic solution (eye drop). [1] [4]

Contents

Side effects of dipivefrine include local eye reactions among others. Dipivefrine is a prodrug of epinephrine (adrenaline) and hence acts as a non-selective adrenergic receptor agonist. [5] It is a substituted phenethylamine and catecholamine and is an ester of epinephrine with much greater fat solubility. [6] [7] [8]

Dipivefrine was first described by 1975. [9] It is widely marketed throughout the world. [10] However, it is no longer available in the United States. [11]

Medical uses

Dipivefrine is used in the treatment of open-angle glaucoma. [2]

Contraindications

Use in narrow-angle glaucoma may be dangerous because it could make the eye susceptible to an attack of angle closure, [3] causing an increase in pressure and pain and possibly loss of vision.

Side effects

The most common side effects of dipivefrine are burning, stinging, and other irritations of the eye. Possible but uncommon side effects are the same as those of epinephrine and include tachycardia (fast heartbeat), hypertension (high blood pressure) and arrhythmias (irregular heartbeat). [3]

Pharmacology

Dipivefrine penetrates the cornea and is then hydrolysed to epinephrine by esterase enzymes. [8] It increases outflow of the aqueous humour and also reduces its formation (mediated by its action on α1- and α2-adrenergic receptors), thus reducing pressure inside the eye. It also increases the conductivity of trabecular filtering cells (a β2-adrenergic-receptor-mediated action). It is preferred to epinephrine because it is longer-acting, more consistent in its action, and better-tolerated. [2]

Chemistry

Dipivefrine, also known as epinephrine dipivalate or as 3,4-dipivalyloxy-β-hydroxy-N-methylphenethylamine, is a substituted phenethylamine and catecholamine. [6] It is the 3,4-dipivalate ester of epinephrine (adrenaline). [6]

The experimental log P of dipivefrine is 1.7 and its predicted log P ranges from 1.49 to 3.71. [6] [1] [12] It is dramatically more lipophilic (600-fold) than epinephrine, [7] [8] [4] which is highly hydrophilic and has a log P of -1.37. [13] The lipophilicity of dipivefrine allows it to penetrate the cornea much more readily (17-fold) than epinephrine. [7] [8] [4] Eye drops containing 0.1% dipivefrine have similar effectiveness to conventional eye drops containing 2% epinephrine in lowering intraocular pressure. [4]

Dipivefrine is used pharmaceutically mainly as the hydrochloride salt. [14] [10]

A similar compound that was never marketed is pivenfrine, which is the 3-pivalate ester of phenylephrine. [14]

History

Dipivefrine was first described in the scientific literature by 1975. [9]

Beta blockers, also spelled β-blockers, are a class of medications that are predominantly used to manage abnormal heart rhythms (arrhythmia), and to protect the heart from a second heart attack after a first heart attack. They are also widely used to treat high blood pressure, although they are no longer the first choice for initial treatment of most patients.

<span class="mw-page-title-main">Pilocarpine</span> Medication used to treat glaucoma and dry mouth

Pilocarpine is a lactone alkaloid originally extracted from plants of the Pilocarpus genus. It is used as a medication to reduce pressure inside the eye and treat dry mouth. As an eye drop it is used to manage angle closure glaucoma until surgery can be performed, ocular hypertension, primary open angle glaucoma, and to constrict the pupil after dilation. However, due to its side effects, it is no longer typically used for long-term management. Onset of effects with the drops is typically within an hour and lasts for up to a day. By mouth it is used for dry mouth as a result of Sjögren syndrome or radiation therapy.

<span class="mw-page-title-main">Phenylephrine</span> Decongestant medication

Phenylephrine, sold under the brand names Neosynephrine and Sudafed PE among numerous others, is a medication used as a decongestant for uncomplicated nasal congestion, used to dilate the pupil, used to increase blood pressure, and used to relieve hemorrhoids. It can be taken by mouth, as a nasal spray, given by injection into a vein or muscle, applied to the skin, or as a rectal suppository.

An adrenergic agonist is a drug that stimulates a response from the adrenergic receptors. The five main categories of adrenergic receptors are: α1, α2, β1, β2, and β3, although there are more subtypes, and agonists vary in specificity between these receptors, and may be classified respectively. However, there are also other mechanisms of adrenergic agonism. Epinephrine and norepinephrine are endogenous and broad-spectrum. More selective agonists are more useful in pharmacology.

<span class="mw-page-title-main">Betaxolol</span> Chemical compound

Betaxolol is a selective beta1 receptor blocker used in the treatment of hypertension and angina. It is also a adrenergic blocker with no partial agonist action and minimal membrane stabilizing activity. Being selective for beta1 receptors, it typically has fewer systemic side effects than non-selective beta-blockers, for example, not causing bronchospasm as timolol may. Betaxolol also shows greater affinity for beta1 receptors than metoprolol. In addition to its effect on the heart, betaxolol reduces the pressure within the eye. This effect is thought to be caused by reducing the production of the liquid within the eye. The precise mechanism of this effect is not known. The reduction in intraocular pressure reduces the risk of damage to the optic nerve and loss of vision in patients with elevated intraocular pressure due to glaucoma.

<span class="mw-page-title-main">Adrenaline</span> Hormone and medication

Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions. It appears as a white microcrystalline granule. Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata. It plays an essential role in the fight-or-flight response by increasing blood flow to muscles, heart output by acting on the SA node, pupil dilation response, and blood sugar level. It does this by binding to alpha and beta receptors. It is found in many animals, including humans, and some single-celled organisms. It has also been isolated from the plant Scoparia dulcis found in Northern Vietnam.
