Ivernew
Ivernew Uses, Dosage, Side Effects, Food Interaction and all others data.
Ivernew selectively binds and with high affinity to glutamate-gated chloride ion channels, which occur in invertebrate nerve and muscle cells leading to an increase in the permeability of cell membranes to chloride ions with hyperpolarization of the nerve or muscle cell and, ultimately, death of the parasite.
Ivernew is a semisynthetic, anthelminitic agent. It is an avermectin which a group of pentacyclic sixteen-membered lactone (i.e. a macrocyclic lactone disaccharide) derived from the soil bacterium Streptomyces avermitilis. Avermectins are potent anti-parasitic agents. Ivernew is the most common avermectin. It is a broad spectrum antiparasitic drug for oral administration. It is sometimes used to treat human onchocerciasis (river blindness). It is the mixture of 22,23-dihydro-avermectin B1a (at least 90%) and 22,23-dihydro-avermectin B1b (less than 10%).

Uses
Ivernew is used for the treatment of the following infections:
Strongyloidiasis of the intestinal tract. Ivernew is used for the treatment of intestinal (i.e., nondisseminated) strongyloidiasis due to the nematode parasite Strongyloides stercoralis.
This indication is based on clinical studies of both comparative and open-label designs, in which 64-100% of infected patients were cured following a single 200-mcg/kg dose of ivermectin.
Onchocerciasis: Ivernew is used for the treatment of onchocerciasis due to the nematode parasite Onchocerca volvulus.
This indication is based on randomized, double-blind, placebo-controlled and comparative studies conducted in 1427 patients in onchocerciasis-endemic areas of West Africa. The comparative studies used diethylcarbamazine citrate (DEC-C).
NOTE: Ivernew has no activity against adult Onchocerca volvulus parasites. The adult parasites reside in subcutaneous nodules which are infrequently palpable. Surgical excision of these nodules (nodulectomy) may be considered in the management of patients with onchocerciasis, since this procedure will eliminate the microfilariae-producing adult parasites.
Ivernew is also used to associated treatment for these conditions: Acne Rosacea, Ascaris lumbricoides infection, Cutaneous larva migrans, Demodicidosis, Gnathostomiasis, Mansonella ozzardi infection, Mansonella streptocerca infection, Oesophagostomiasis, Onchocerciasis, Pediculosis Capitis, Scabies, Trichuriasis, Wuchereria bancroftii infection
How Ivernew works
Ivernew binds selectively and with high affinity to glutamate-gated chloride ion channels in invertebrate muscle and nerve cells of the microfilaria. This binding causes an increase in the permeability of the cell membrane to chloride ions and results in hyperpolarization of the cell, leading to paralysis and death of the parasite. Ivernew also is believed to act as an agonist of the neurotransmitter gamma-aminobutyric acid (GABA), thereby disrupting GABA-mediated central nervous system (CNS) neurosynaptic transmission. Ivernew may also impair normal intrauterine development of O. volvulus microfilariae and may inhibit their release from the uteri of gravid female worms.

Food Interaction

Ivernew Alcohol interaction
[Moderate] GENERALLY AVOID:
Alcohol may increase the plasma concentrations of ivermectin.
The mechanism of interaction is unknown.
In 20 healthy, nonsmoking patients with onchocerciasis, mean plasma ivermectin concentrations at 1, 3 and 4 hours post-dose (150 mcg/kg) were approximately 34% to 40% higher in the group given the medication with 750 mL of beer (4.5% v/v alcohol) than in controls who ingested the medication with water.
There were no side effects in either study or control subjects.
However, there have been anecdotal reports of increased central nervous system adverse effects and postural hypotension in patients who combined ivermectin with alcohol.
Patients receiving ivermectin therapy should preferably avoid the consumption of alcohol to prevent any undue adverse effects of ivermectin.
Ivernew Drug Interaction
Unknown: diphenhydramine, diphenhydramine, ubiquinone, ubiquinone, acetylcysteine, acetylcysteine, bioflavonoids, bioflavonoids, acetaminophen, acetaminophen, cyanocobalamin, cyanocobalamin, ascorbic acid, ascorbic acid, cholecalciferol, cholecalciferol, zinc sulfate, zinc sulfate, cetirizine, cetirizine

Who should not take Ivernew?
You will need to have a stool exam after taking Ivernew to make sure the infection is gone. Some patients may need to take another dose of Ivernew to treat the infection. Ivernew may make you feel dizzy. To lower the chance of feeling dizzy or passing out, rise slowly if you have been sitting or lying down. Be careful going up and down stairs.
