Final answer:
Ketamine is a dissociative anesthetic with analgesic effects at subanesthetic doses, a weak bronchodilator effect, and can reduce bronchial secretions. It's used in both human and veterinary medicine.
Step-by-step explanation:
The drug 16A-109 Ketamine is known for its use as a dissociative anesthetic in both human and veterinary medicine. At subanaesthetic doses, ketamine has analgesic effects, providing pain relief without loss of consciousness. It is commonly administered intravenously or intramuscularly, but for illicit use, it is often converted into a powder form. Notably, ketamine does have a weak bronchodilator effect, but it is not primarily used as a spinal anesthetic. Instead, it's chosen for its ability to induce a state of general anesthesia characterized by immobility, analgesia, amnesia, and reduced autonomic responsiveness to noxious stimuli. Ketamine can also reduce bronchial secretions, adding to its list of effects.
