Drug Interaction Integrate drug-drug
interactions in your softwareAbiraterone The serum concentration of Guanine can be increased when it is combined with Abiraterone. Acebutolol The risk or severity of adverse effects can be increased when Acebutolol is combined with Guanine. Acetazolamide Acetazolamide may increase the excretion rate of Guanine which could result in a lower serum level and potentially a reduction in efficacy. Adalimumab The serum concentration of Guanine can be decreased when it is combined with Adalimumab. Adenosine The therapeutic efficacy of Adenosine can be decreased when used in combination with Guanine. Allopurinol The serum concentration of Guanine can be increased when it is combined with Allopurinol. Alprazolam The therapeutic efficacy of Alprazolam can be decreased when used in combination with Guanine. Amobarbital The serum concentration of Guanine can be decreased when it is combined with Amobarbital. Amphetamine The risk or severity of adverse effects can be increased when Amphetamine is combined with Guanine. Atenolol The risk or severity of adverse effects can be increased when Atenolol is combined with Guanine.
