Abstract:
A 3-year-old, male castrated domestic shorthair cat presented for sudden onset of severe lethargy and loss of balance a few hours after potentially ingesting capsules containing progesterone. Elevated serum progesterone was confirmed. Supportive care and time resulted in complete resolution of the clinical signs with no long-term complications or recurrence of clinical signs noticed after 1-month follow-up. This is the first description of progesterone intoxication inducing neurological signs in a cat.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
