The new J&J product, derived from esketamine, a form of ketamine, would be inhaled via a nasal spray, providing — according to reports — almost instantaneous relief from the symptoms of severe depression.
Intended to be used as a fast-acting antidepressant, patients would use the new drug to counteract incidences of major depression alongside suicidal tendencies by inhaling — snorting — an atomized liquid through the nose, noted Bloomberg in a recent report.
Billed as being the first prominent pharmaceutical breakthrough in the fight against depression since the 1987 advent of Prozac, J&J has hailed the new drug's speedy reaction time when compared to the several weeks required under standard drug-based therapies.
"The rates of response in this treatment-resistant population is better than we've seen," Dunn said, adding that the "rapid timeline of response is better."
"There's nothing approved that gets patients better this fast," he remarked, cited by Bloomberg.
Noting that the use of ketamine as a recreational drug is "relatively uncommon," the expert advisory panel pointed to hallucinogenic drug-abuse rates for LSD and ecstasy in the US as being much higher.
"Those of us who have seen it used know the adverse-event profile is large," Meisel said, cited by Bloomberg.
Remarkable for this particular drug-approval process was the panel's taking into account of the direct patient experience with the drug in trials.
"We don't take the patient voice into account enough," he agreed.
J&J will market the drug under the trade name Spravato, according to a statement from the multinational corporation.
Inducing an anesthetic trance-like state, ketamine was first discovered in 1962, tested on human subjects in 1964 and used liberally by the US thereafter in surgical procedures during the Vietnam War.
Gaining popularity in the latter part of the 20th century as a party drug, ketamine — often referred to as ‘Vitamin K' — in 1999 was classified as a controlled substance in the US.
