A concept of a Probable Autoinjector for Bio-threat Agents

Chemical and biological weapons can be used during conflicts and by terrorists to injure or kill humans and animals. Chemical weapons contain toxic chemicals and biological weapons contain pathogenic organisms. With proper protective equipments and training, the lethal effects of chemical and biological warfare agents can be minimised. First aid kit is available that contain detection, decontamination and medical protection for chemical warfare agents including autoinjectors, for rapid administration and faster absorption of drugs. The autoinjectors are safe and available for life saving drugs like atropine sulphate and pralidoxime chloride (nerve agent poisoning), epinephrine (anaphylaxis), diazepam (seizures) and sumatriptan (migraine). For bio-threat agents doxycycline alone is available as a broad spectrum antibiotic in the first aid kit. Majority of the bacterial agents are gram negative and hence amikacin drug cartridge was developed for the existing autoinjector. The advantage of amikacin is its safety, stability, can be given prophylactically and supplemented with other antibiotics when medical attention arrives. The usability and tolerability of amikacin administered repeatedly through autoinjector was studied using various haematological, biochemical and oxidative stress parameters in animal models. The results are promising and as there is no antibiotic autoinjector available, amikacin autoinjector can be considered for bio-threat agents.
