Ivactin

Ivactin Uses, Dosage, Side Effects, Food Interaction and all others data.

Ivactin 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.

Ivactin 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. Ivactin 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

Ivactin is used for the treatment of the following infections:

Strongyloidiasis of the intestinal tract. Ivactin 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: Ivactin 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: Ivactin 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.

Ivactin 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 Ivactin works

Ivactin 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. Ivactin 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. Ivactin may also impair normal intrauterine development of O. volvulus microfilariae and may inhibit their release from the uteri of gravid female worms.

Diarrhoea, nausea, vomiting, dizziness, pruritus, urticaria, rash, arthralgia, fever, myalgia, asthenia, postural hypotension, tachycardia, oedema, lymphadenopathy, sore throat, cough, headache, somnolence, transient eosinophilia, raised liver enzyme values.

Toxicity

LD50 = 29.5 mg/kg (Mouse, oral). LD50 = 10 mg/kg (Rat, oral). Adverse effects include muscle or joint pain, dizziness, fever, headache, skin rash, fast heartbeat.

Precaution

Concurrent Loa loa infection, impaired blood-brain barrier function due to infection.

Interaction

Bioavailability may be increased by alcohol, levamisole.

Food Interaction

  • Take on an empty stomach.

Ivactin 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.

Volume of Distribution

The volume of distribution is 3 to 3.5 L/kg and it does not cross the blood-brain barrier.

Elimination Route

Moderately well absorbed. Improved absorption with high fat meal.

Half Life

16 hours (also reported at 22-28 hours)

Elimination Route

Ivactin is metabolized in the liver, and ivermectin and/or its metabolites are excreted almost exclusively in the feces over an estimated 12 days, with less than 1% of the administered dose excreted in the urine.

Pregnancy & Breastfeeding use

Category C: Either studies in animals have revealed adverse effects on the foetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the foetus.

Ivactin displays antidiabetic activities by reducing blood glucose and cholesterol levels, and also by improving insulin sensitivity in an FXR-dependent manner.

Who should not take Ivactin?

You will need to have a stool exam after taking Ivactin to make sure the infection is gone. Some patients may need to take another dose of Ivactin to treat the infection. Ivactin 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.

A lack of these nutrients can contribute to hair loss.

Does Ivactin cause blood clots?

Ivactin  has a minimal effect on coagulation and concern about mass treatment for this reason appears to be unjustified.

Ivactin did not induce anxiety-like behavior neither affected corticosterone levels of juvenile rats.

Can Ivactin help asthma?

This is the first study to demonstrate that Ivactin is an effective suppressor of inflammation and may be efficacious in the treatment of non-infectious airway inflammatory diseases such as allergic asthma.
