1Drug names ending in pam or lam are almost always benzodiazepines. It is a quick way to pick the class out of somebody's medication list.
The ending tracks a shared chemical backbone, so the shortcut is not a coincidence. Keep a rough rule alongside it: this class suits sharp fear better than it suits ongoing worry. It can take the top off a surge that arrives in minutes, and it does much less for the person whose anxiety hums along all week.
Islamic evidence
Moses, do not be afraid (Quran 27:10). The fear is met in the moment it arrives and answered without a word of rebuke, and that sudden kind of fear is what this class is for.
“Throw down your staff,’ but when he saw it moving like a snake, he turned and fled. ‘Moses, do not be afraid! The messengers need have no fear in My presence”
Qur'an 27:10
Psychological evidence
A review of the perseverative cognition idea argues that worry keeps physiological stress activation running both before and after events, which is a different shape of problem from a sudden surge. That difference is the reason a fast, short-lived agent fits one better than the other. The review is about worry and the body rather than a comparison of drugs, so the pairing is inference and not something measured.

Review detail
Why it works. A drug that acts within the hour matches a problem that arrives in minutes, not one that runs for months.
