Phenobarbital lowers the plasma levels of dicumarol and causes a reduce in anticoagulant exercise as calculated with the prothrombin time. Barbiturates can induce hepatic microsomal enzymes causing improved metabolism and diminished anticoagulant reaction of oral anticoagulants (e.
Symptoms of barbiturate dependence are just like These of chronic alcoholism. If a person appears to get intoxicated with alcohol to the degree that is radically disproportionate to the quantity of alcohol in her or his blood, using barbiturates should be suspected.
