At the same time, carbon dioxide diffuses out of the blood and into the air through the respiratory membrane. The exchange of oxygen into the blood and carbon dioxide into the air allows the blood leaving the lungs to provide oxygen to the bodyâs cells, while depositing carbon dioxide waste into the air. Control of Breathing. Breathing is controlled by the brain and may be controlled both consciously and unconsciously.
Ninety patients were assigned into three groups and received atorvastatin (10-40 mg/day) or fenofibrate (160-200 mg/day) or combination of low-dose atorvastatin (5 mg/day) and fenofibrate (160 mg/day).o significant difference was reported in safety profile between the two groups. To conclude, the results suggest that combination therapy with low-dose atorvastatin and fenofibrate is more efficacious, with no increase in adverse effects when compared with monotherapies with individual drugs for mixed hyperlipidemia.
Plasma concentrations of total radioactivity (Lovastatin plus 14C-metabolites) peaked at 2 hours and declined rapidly to about 10% of peak by 24 hours postdose. Absorption of Lovastatin, estimated relative to an intravenous reference dose, in each of four animal species tested, averaged about 30% of an oral dose.
