Tetracaine Hydrochloride Powder, telethiimazole, anthelmintic, etc., named as -2,3,5-tetra-tetrazole, tetracaine tetrazolochemical [2,1-b]thiophene salt, 12n2shcl, relative 24.75, cas5086 Molecular weight -7-8. White crystalline powder, none, tasteless, tasteless, with a bitter taste. A simple and fast, excellent selection of recipes. It doesn't seem to be of any type.
It is a high-efficiency broad-spectrum anthelmintic drug with an excellent curative effect on infections like roundworms, hookworms, and pinworms. Its levorotatory body, levamisole, is the influential body. In recent years, researchers believe that it has the potential to become an immune restorer. Tetraimidazole, an imidazole derivative, has been extensively studied since its anthelmintic effect was discovered in 1966. In particular, levamisole, the levamisole of tetramisole, has received significant attention because its deworming product is twice as strong as that of tetramisole. In my country, levamisole was synthesized in 1973. Through extensive deworming experiments, it was proved that it is an ideal drug for expelling major nematodes in livestock and poultry.
According to records, it has the advantages of a broad spectrum, high efficiency, good drug sources, and stable properties. The aqueous solution of levamisole hydrochloride will decompose after boiling for 5 days (ph=2～8). His 0.5% aqueous solution, stored at 25°C and pH4 for 2 years, lost 1.8% of activated carbon. It shows that the acid solution is very stable. In an alkaline solution, it can be hydrolyzed to form water-insoluble metabolite thiobendazoline. In recent years, it has been found that levamisole also has immunomodulatory effects, so it has received more attention from the medical and veterinary circles.
In vitro, Tetracaine Hydrochloride Powder is orally non-toxic and effective at low-dose injectable doses tested against all adult and juvenile gastrointestinal and lung nematodes in 14 different hosts. Tetramisole (10 μg/mL) acts on worms, causing sustained contractions of isolated muscles. Tetramisole acts on the Ascaris muscle, lowering its resting potential from 34 mV to 10 mV. It elicits an enhanced muscle twitch response in cats previously stimulated directly or indirectly with high K Tetramisole (0.1 mM). Tetramisole (0.1 mM) in chickens enhances the preparation of the twitch response and reverses the inhibitory effect of Tubocurarine, resulting in reversible neuromuscular blockade and muscle contractures.
In vivo studies, Tetracaine Hydrochloride Powder (2 mg/kg, i.v.) in cats produced a muscular contraction of the nictitating membrane after a 20-second delay, followed by a brief drop in blood pressure followed by a sustained rise lasting up to 20 minutes. Tetramisole (2 mg/kg) produced a more excellent contractile response than non-reserpine-treated cats. Tetramisole (5-10 mg/kg, i.v.) caused a transient acute drop in blood pressure in rabbits, partially antagonistic to atropine. After 3 weeks of treatment with Tetramisole (15 mg/kg), the number of fecal nematode eggs in the flock increased and continued to increase up to 12 weeks.
