A synthetic, bacteriostatic, antimycobacterial agent, ethambutol’s exact mechanism of action is not known. Ethambutol is only active against actively dividing mycobacteria. It enters mycobacterial cells and interferes with RNA synthesis. Ethambutol does not have appreciable activity against other bacteria or fungi. Resistance can occur and is thought to develop in a step-wise manner. Cross-resistance with other antimycobacterial agents has not been reported.
The principal use of ethanol in veterinary medicine is for the treatment of ethylene glycol or methanol toxicity. While fomepizole (4-methyl pyrazole) is now the treatment of choice for ethylene glycol poisoning, alcohol is a readily available and an economical alternative when patients present within a few hours after ingestion. Percutaneous injection of ethanol 95% has been used successfully to treat feline hyperthyroidism. Ethyl alcohol has also been used in aerosol form as a mucokinetic agent in horses.
