CodeCAS 59-42-7

Characteristics of Phenylephrine

Phenylephrine hydrochloride - white or white with a slightly yellowish white crystalline powder and odorless. The easily soluble in water and alcohol.

Pharmacological Properties of Phenylephrine

Pharmachologic effect
vasoconstrictor, alpha-agonists.

Stimulates postsynaptic alpha-adrenergic receptors. Causes arteriolar narrowing, increased blood pressure (with a possible reflex bradycardia), increased peripheral vascular resistance. It has a slight stimulating effect on the brain and spinal cord. Reduces blood flow - kidney, skin, abdominal organs and limbs. Narrowing of the pulmonary blood vessels and increases blood pressure in the pulmonary artery. As has antikongestivnoe vasoconstrictor effect: reduces swelling and congestion of the nasal mucosa, the severity of the manifestations of exudative, restores free breathing; It lowers the pressure in the paranasal cavities and in the middle ear.

When applied topically in ophthalmology causes mydriasis, improves the outflow of intraocular fluid and constricts blood vessels of the conjunctiva. After instillation of phenylephrine reduces the iris dilator muscle, thereby causing expansion of the pupil, and the smooth muscle of the arterioles of the conjunctiva. Pupil size is reset for 4-6 hours. Since phenylephrine has little effect on the ciliary muscle, mydriasis occurs without cycloplegic. Phenylephrine is easily penetrates into the eye tissue, pupil dilation occurs within 10-60 minutes after a single instillation. Mydriasis is maintained for 4-6 hours. Due to the significant reduction in the iris dilator muscle, 30-45 minutes after instillation of moisture anterior chamber may be detected by the pigment particles from the pigment of the iris leaf.

Biotransformiroetsa in the liver and the gastrointestinal tract (without the participation of catechol-O-methyltransferase). Excreted by the kidneys as metabolites. The action begins immediately after the injection and lasts for 20 (after the on / in the introduction) - 50 minutes (p / injection) - 1-2 hours (after the / m injection). When applied topically exposed to systemic absorption.

The application of phenylephrine at subdural and inhalation anesthesia (to maintain adequate blood pressure and extension subdural anesthesia), anaphylaxis, in paroxysmal supraventricular tachycardia, reperfusion arrhythmias (Bertsolda-Jarisch reflex), priapism, secretory prerenal anuria.

Indications for Phenylephrine
For parenteral use: acute hypotension, shock states (including traumatic shock, toxic shock), vascular insufficiency (including on the background of an overdose of vasodilators), local anesthesia (as a vasoconstrictor).

In otorhinolaryngology (nasal drops, spray) to facilitate breathing through the nose - colds, flu, hay fever or other allergic diseases of the upper respiratory tract, accompanied by acute rhinitis or sinusitis.

In ophthalmology (eye drops): iridocyclitis (for the prevention of adhesions and rear reduce exudation); mydriasis during ophthalmoscopy and other diagnostic procedures necessary to monitor the state of the rear segment of the eye; holding provocative test in patients with narrow profile of anterior chamber angle and suspected closure glaucoma; differential diagnosis of the type of injection of the eyeball; in ophthalmic surgery in the preoperative preparation for the expansion of the pupil (10% solution); in laser interventions in the fundus and vitreoretinal surgery; treatment glaukomotsikliticheskih crises; treatment of "red eye syndrome" (2.5% solution) (to reduce redness and irritation of the eye membranes).

Contraindications for Phenylephrine

Hypersensitivity. Injection: hypertension (requires monitoring of blood pressure and rate of infusion), hypertrophic obstructive cardiomyopathy, ventricular fibrillation, decompensated heart failure, marked atherosclerosis, severe coronary artery disease, lesions of cerebral arteries, pheochromocytoma.

Eye drops: narrow-angle or angle-closure glaucoma, advanced age for serious violations of the cardiovascular or cerebrovascular system; additional mydriasis during surgery in patients with impaired eyeball integrity, as well as in violation of tear production; hyperthyroidism, hepatic porphyria, congenital deficiency of glucose-6-phosphate dehydrogenase, children under the age of 12 years and patients with aneurysms of the arteries (10% solution), children with reduced body weight (2.5% solution).

Nasal drops: diseases of the cardiovascular system (including koronaroskleroza, angina), hypertensive crisis, hyperthyroidism, diabetes mellitus.

Nasal spray: diseases of the cardiovascular system (including the expressed atherosclerosis, angina pectoris, tachycardia), thyroid gland (hyperthyroidism), diabetes, hypertension, children under 6 years.

Restrictions apply

Injection: metabolic acidosis, hypercapnia, hypoxia, atrial fibrillation, angle-closure glaucoma, hypertension in the pulmonary circulation, hypovolemia, severe aortic stenosis, a shock in myocardial infarction, tachyarrhythmia, ventricular fibrillation, bradycardia, occlusive vascular disease (divided into . history) - arterial thrombosis, atherosclerosis, thromboangiitis obliterans (Buerger's disease), Raynaud's disease, susceptibility to vascular spasms (including with frostbite), diabetic endarteritis, hyperthyroidism, advanced age, the age of 18 years; nasal drops: children up to 6 years.

Pregnancy and breast-feeding

Application of pregnancy and lactation is possible only if the potential benefit to the mother outweighs the potential risk to the fetus and child.

Category effects on the fetus by FDA - C.

Side effects of Phenylephrine

systemic effects

Cardio-vascular system and blood (blood, hemostasis): increase or decrease in blood pressure, chest pain, palpitations, tachycardia, cardiac arrhythmias, including ventricular, arterial hypertension, reflex bradycardia, coronary artery occlusion, pulmonary embolism, myocardial infarction (in some cases using a 10% solution of eye drops in elderly people who have had the disease of the cardiovascular system).

From the nervous system and sensory organs: headache, dizziness, agitation, anxiety, irritability, fatigue, insomnia, tremor, paresthesia; eye drops - intraocular pressure increase, reactive miosis (the next day after the application, at which time repeated instillation of drugs may produce mydriasis less pronounced than before, the effect often seen in elderly patients).

Other: nausea or vomiting, respiratory depression, oliguria, acidosis, pale skin, sweating.

Local reactions: injection - local ischemia of the skin at the injection site necrosis and scab formation in contact with the tissues or s / c injection; eye drops - burning sensation (at the beginning of the application), blurred vision, irritation, discomfort, lacrimation; nasal dosage forms: burning, tingling or tingling in the nose.

Interaction

Oxytocin, MAO inhibitors (including procarbazine, selegiline), tricyclic antidepressants, ergot alkaloids, sympathomimetics enhance pressor effect, and arrhythmogenic last phenylephrine. Alpha-blockers (phentolamine), phenothiazines, furosemide and other diuretics inhibit vasoconstriction. Against the background of reserpine possible hypertension (due to catecholamine depletion in adrenergic neurons increased sensitivity to sympathomimetics). Thyroid hormones increase the (mutually) the risk of coronary heart disease (especially in coronary atherosclerosis). Mydriatic effect of phenylephrine is enhanced by the local application of atropine. Using a 10% solution of phenylephrine in combination with systemic use of beta blockers may cause severe hypertension.

Overdose

Manifested ventricular premature beats and short paroxysms of ventricular tachycardia, a feeling of heaviness in the head and limbs, a significant increase in blood pressure.

Treatment: in / with the introduction of alpha-blockers (such as phentolamine) and beta-blockers (for heart rhythm disturbances).

Precautions

During treatment should monitor the ECG, blood pressure, wedge pressure in the pulmonary artery, cardiac output, blood circulation in the limbs and at the injection site. When hypertension is necessary to maintain the garden level of 30-40 mmHg lower than usual. Before the start of or during the treatment of states of shock obligatory correction of hypovolemia, hypoxia, acidosis, hypercapnia. The sharp increase in blood pressure, bradycardia or tachycardia, persistent cardiac arrhythmias require discontinuation of treatment. To prevent re-BP reduction after the drug dose should be reduced gradually, especially after prolonged infusion. The infusion is resumed If the garden is reduced to 70-80 mm Hg

During therapy eliminated a potentially hazardous activities that require speed motor and mental reactions.

When applied topically after absorption through mucosal phenylephrine can cause systemic effects. In this connection it should avoid the use of phenylephrine 10% in the form of eye drops in infants and elderly patients. Use of 10% or 2.5% solution of phenylephrine with MAO inhibitors, as well as 21 days after the cancellation must be done with care, because may develop systemic adrenergic effects.
