Well absorbed following oral administration.|MAX UPTAKE @ 1 HR FOR MOST RAT TISSUES WHILE BRAIN, DIAPHRAGM, STOMACH, & VEIN SHOWED MAX LEVELS @ 24 HR. LEVELS NEGLIGIBLE IN 28 DAYS.

(3-)-H-LABELED CYCLANDELATE WAS DETECTED & QUANTITATED. EFFECTIVE HALF-LIFE VALUES IN VARIOUS RAT TISSUES WERE 2.8-4.1 DAYS.

Cyclandelate produces peripheral vasodilation by a direct effect on vascular smooth muscle. Pharmacological action may be due to calcium-channel antagonism.|...MOST OF ITS PHARMACOLOGICAL PROPERTIES ARE VERY SIMILAR TO THOSE OF PAPAVERINE & OF MANY SYNTHETIC ANTISPASMODICS PROMOTED PRIMARILY FOR EFFECTS ON SMOOTH MUSCLE.|PAPAVERINE IS POTENT INHIBITOR OF CYCLIC NUCLEOTIDE PHOSPHODIESTERASE FOUND IN MANY TISSUES & CAN INCR CONCN OF CYCLIC ADENOSINE 3',5'-MONOPHOSPHATE (CYCLIC AMP). SINCE CYCLIC AMP HAS BEEN IMPLICATED AS POSSIBLE MEDIATOR OF BETA-ADRENERGIC RELAXATION OF SMOOTH MUSCLE, SUCH MECHANISM OF ACTION...IS PLAUSIBLE. /PAPAVERINE/

CYCLANDELATE APPEARS TO PRODUCE LITTLE SERIOUS TOXICITY. HOWEVER, ORAL DOSES OF 200 MG OR MORE ARE ASSOC WITH SIGNIFICANT INCIDENCE OF UNPLEASANT SIDE EFFECTS, INCL GASTROINTESTINAL UPSETS, FLUSHING, TINGLING, HEADACHE, DIZZINESS, & SWEATING.|SIDE EFFECTS INCLUDE...NAUSEA...& HYPOTENSION.|...IT HAS BEEN CLAIMED THAT CYCLANDELATE REDUCED OPHTHALMIC BLOOD PRESSURE BUT INCR FLOW IN RETINAL ARTERIES. IT APPEARS THAT CYCLANDELATE PRESENTS NO SIGNIFICANT THREAT OF RAISING OCULAR PRESSURE IN OPEN-ANGLE GLAUCOMA NOR ANY THREAT OF PRECIPITATING ANGLE-CLOSURE GLAUCOMA...
