The structure-activity relationship of the drug class has been explored to a reasonable extent. The optimal substitution pattern is fairly tightly defined (i.e. N,N-diethyl on the amine nitrogen, 4-ethoxy on the benzyl ring and 5-nitro on the benzimidazole ring), but even derivatives incorporating only some of these features are still potent opioids.
Benznidazole is an antiparasitic medication used in the treatment of Chagas disease. [2] While it is highly effective in early disease, the effectiveness decreases in those who have long-term infection. [3] It is the first-line treatment given its moderate side effects compared to nifurtimox. [1] It is taken by mouth. [2] Side effects are ...
Some patients request to be switched to a different narcotic due to stigma associated with a particular drug (e.g. a patient refusing methadone due to its association with opioid addiction treatment). [4] Equianalgesic charts are also used when calculating an equivalent dosage of the same drug, but with a different route of administration.
It is a member of the benzimidazole family of medications for worms. [1] Triclabendazole was approved for medical use in the United States in 2019. [3] [4] It is on the World Health Organization's List of Essential Medicines. [5] For human use, it can be obtained from the World Health Organization. [2] It is also used in animals. [6]
Benzimidazole was discovered during research on vitamin B 12. The benzimidazole nucleus was found to be a stable platform on which drugs could be developed. [3] Benzimidazole is produced by condensation of o-phenylenediamine with formic acid, [4] or the equivalent trimethyl orthoformate: C 6 H 4 (NH 2) 2 + HC(OCH 3) 3 → C 6 H 4 N(NH)CH + 3 CH ...
Albendazole is a broad-spectrum antihelmintic and antiprotozoal agent of the benzimidazole type. [3] It is used for the treatment of a variety of intestinal parasite infections, including ascariasis, pinworm infection, hookworm infection, trichuriasis, strongyloidiasis, taeniasis, clonorchiasis, opisthorchiasis, cutaneous larva migrans, giardiasis, and gnathostomiasis, among other diseases.
Melarsoprol (for treatment of sleeping sickness caused by Trypanosoma brucei) Eflornithine (for sleeping sickness) Metronidazole (for vaginitis caused by Trichomonas) Tinidazole (for intestinal infections caused by Giardia lamblia) Miltefosine (for the treatment of visceral and cutaneous leishmaniasis, currently undergoing investigation for ...
It is a systemic benzimidazole fungicide that is selectively toxic to microorganisms and invertebrates (especially earthworms), but relatively nontoxic toward mammals. [3] Due to the prevalence of resistance of parasitic fungi to benomyl, it and similar pesticides are of diminished effectiveness. Nonetheless, it is widely used.
