Caffeine + theophylline + L-theanine. L-theanine (an amino acid unique to tea) modulates glutamate and produces an 'alpha-wave' calming overlay on caffeine's stimulation, hence tea's reputation as a 'cleaner' stimulant than coffee. (1) ·
Highly β1-selective adrenergic antagonist. Greater selectivity than metoprolol or atenolol. (1) ·
Primary alkaloid is (S)-(-)-cathinone, a phenylpropanolamine close kin to amphetamine. Releases dopamine and norepinephrine. Also contains cathine (=norpseudoephedrine) and norephedrine. (1) ·
The d-enantiomer is a highly β1-selective antagonist; the l-enantiomer triggers endothelial nitric-oxide–mediated vasodilation. Unique among beta blockers for this NO mechanism. (1)
