These studies suggest that atorvastatin and simvastatin can lower Lp(a) levels, with atorvastatin being more effective, and that apomorphine and d-amphetamine can mitigate hyperactivity and attention deficits caused by damage to dopaminergic A10 neurons in rats.

Understanding the Effects of Atorvastatin and Apomorphine on Health
Atorvastatin 10 mg (A10) and Lipoprotein(a) Levels
Atorvastatin's Impact on Lipoprotein(a) in Hypercholesterolemic Patients
Atorvastatin, commonly prescribed at a dosage of 10 mg/day (A10), has been studied for its effects on lipoprotein(a) [Lp(a)] levels in hypercholesterolemic patients who are at high cardiovascular risk. Research indicates that atorvastatin significantly reduces Lp(a) levels in these patients. In a study involving 391 hypercholesterolemic patients, those treated with A10 showed a 6% reduction in Lp(a) levels after six weeks of treatment. This reduction was statistically significant (P<0.001), highlighting atorvastatin's efficacy in lowering Lp(a) levels, which is a crucial factor in managing cardiovascular risk.
Comparison with Simvastatin
The same study compared the effects of atorvastatin with simvastatin (20 mg/day, S20). Both medications were effective in reducing Lp(a) levels, but atorvastatin showed a slightly greater reduction. Simvastatin-treated patients experienced a 0.02% reduction in Lp(a) levels (P=0.046). Despite the differences in the magnitude of reduction, both statins were effective, and their efficacy did not significantly differ in lowering Lp(a) levels.
Apolipoprotein(a) Fragment Levels
Interestingly, the study also measured the levels of apolipoprotein(a) [apo(a)] fragments before and after treatment. Neither atorvastatin nor simvastatin significantly altered the levels of apo(a) fragments in the patients. This suggests that while atorvastatin effectively reduces Lp(a) levels, it does not impact the fragmentation of apo(a), indicating a specific action on Lp(a) rather than on its fragments.
Apomorphine and Dopaminergic A10 Neurons
Apomorphine's Role in Reducing Locomotor Hyperactivity
Apomorphine (APO), administered in small doses, has been studied for its effects on locomotor hyperactivity caused by lesions in the dopaminergic A10 neurons area. Research involving rats with lesions in the ventral mesencephalic tegmentum region (VMT) demonstrated that very low doses of APO (30 microgram/KG) significantly reduced the behavioral deficits associated with these lesions. This reduction in hyperactivity suggests that APO can effectively mitigate the symptoms caused by the destruction of DA-A10 neurons.
Chronic Administration of d-Amphetamine
In addition to APO, chronic administration of d-amphetamine (d-AMPH) has also been shown to reduce locomotor hyperactivity in rats with VMT lesions. Administering d-AMPH twice daily for 43 days brought the activity levels of lesioned rats back to control levels. These findings support the hypothesis that dopaminergic A10 neurons play a primary role in the VMT behavioral syndrome and that both APO and d-AMPH can help in reactivating DA postsynaptic receptors and strengthening the remaining DA-A10 neurons' function.
Conclusion
In summary, atorvastatin at a dosage of 10 mg/day is effective in reducing Lp(a) levels in hypercholesterolemic patients, although it does not affect apo(a) fragment levels. On the other hand, apomorphine, in small doses, and chronic administration of d-amphetamine can significantly reduce locomotor hyperactivity caused by lesions in dopaminergic A10 neurons. These findings highlight the specific actions of these medications in managing cardiovascular risk and behavioral syndromes, respectively.
