supplement:

Caffeine

Research Papers that Mention the Interaction

“Diltiazem (10 μmol/L) and verapamil (10 μmol/L) inhibited the hypercontractility induced by 3% halothane and 2 mmol/L caffeine in malignant hyperpyrexia susceptible (MHS) muscle.”
Clinical and experimental pharmacology & physiology  •  1989  |  View Paper
“The positive inotropic and the arrhythmogenic effects of caffeine could be diminished by pretreating the fibres with propranolol or Ca antagonists (diltiazem and verapamil).”
Cardiovascular research  •  1985  |  View Paper
“Application of 10 μm verapamil to the bath led to 30% and 52% reductions in the Ca2+ leak caused by the presence of caffeine for the peak and steady-state values of net Ca2+ fluxes, respectively.”
“The effects of Ca2+ channel blockers verapamil and gadolinium) were explored using 6 mm caffeine; both significantly reduced the action of caffeine on tension and on calcium fluxes.”

“The spontaneous rhythmic activity and a phasic contraction induced by caffeine , were blocked by verapamil (3 microM) or by removal of external Ca2+.”
Journal of smooth muscle research = Nihon Heikatsukin Gakkai kikanshi  •  1997  |  View Paper
“Pretreatment with verapamil (1 or 10 μm), nifedipine (0.1 μm) or incubation with Ca2+‐free, EGTA (0.1 mm)‐containing physiological salt solution (PSS) suppressed the contraction produced by caffeine or theophylline in PDA (5 μm)‐treated tissues.”
“ Verapamil (10 μm) prevented the effects of PDA against caffeine‐ or theophylline‐induced relaxation.”
British journal of pharmacology  •  1994  |  View Paper
“At 37 degrees C caffeine induced a phasic contraction and the contraction was inhibited by verapamil or in the absence of Ca.”

“ Caffeine (5 mM)-induced contraction in the presence of verapamil and phentolamine was significantly smaller in SHR than in WKY.”

“ Verapamil and manganese inhibited 4-AP, caffeine and quinine-induced contractures.”

“The spasmogenic activity of caffeine (10 mM) was evaluated in tracheal strips obtained from … (2.8 microM) and cooled to 20 degrees C. The contraction elicited by caffeine … verapamil (100 microM), trifluoperazine (100 and 500 microM) and dantrolene (50 … sensitized tissues but was unaffected by disodium cromoglycate (39 microM).”

“However, the potentiating effect of caffeine was not abolished by verapamil.”
