Modafinil is a non-amphetamine central nervous system (CNS) stimulant used to improve wakefulness in patients with sleep apnea, narcolepsy, or shift work disorder. The exact mechanism of action is unclear, although in vitro studies have shown it to inhibit the reuptake of dopamine by binding to the dopamine reuptake pump, and lead to an increase in extracellular dopamine. The high concentration of dopamine activates D2 receptors on the post-synaptic membrane leading to activation of the Gi signaling cascade. This cascade is inhibitory and ultimately leads to the inhibition of sleep, promoting wakefulness. This action of modafinil is its primary clinically important property. Modafinil is generally a well-tolerated stimulant. The most commonly reported adverse effects of modafinil (less than 10% of users) are a headache, nausea, and decreased appetite. Other commonly reported adverse effects (5% to 10% of users) include anxiety, insomnia, dizziness, diarrhea, and rhinitis

Moexipril is an angiotensin-converting enzyme (ACE) inhibitor for the conversion of angiotensin I into angiotensin II. Angiotensin II is a critical circulating peptide hormone that has powerful vasoconstrictive effects and increases blood pressure. Moexipril is used to treat hypertension, high blood pressure, congestive heart failure, and chronic renal failure as it decreases blood pressure. Moexipril is converted into Moexiprilat through the liver after being ingested which travels in the blood to inhibit ACE which is from the lungs. Angiotensin has many vasoconstrictive effects by binding to angiotensin II type 1 receptor (AT1) in blood vessels, kidneys, hypothalamus, and posterior pituitary. In blood vessels AT1 receptors cause vasoconstriction in the tunica media layer of smooth muscle surrounding blood vessels increasing blood pressure. Less angiotensin II that is circulating lowers the constriction of these blood vessels. AT1 receptors in the kidney are responsible for the production of aldosterone which increases salt and water retention which increases blood volume. Less angiotensin II reduces aldosterone production allowing water retention to not increase. AT1 receptors in the hypothalamus are on astrocytes which inhibit the excitatory amino acid transporter 3 from up-taking glutamate back into astrocytes. Glutamate is responsible for the activation of NMDA receptors on paraventricular nucleus neurons (PVN neurons) that lead to thirst sensation. Since angiotensin II levels are lowered, the inhibition of the uptake transporter is not limited decreasing the amount of glutamate activating NMDA on PVN neurons that makes the individual crave drinking less. This lowers the blood volume as well. Lastly, the AT1 receptors on posterior pituitary gland are responsible for the release of vasopressin. Vasopressin is an anti-diuretic hormone that cases water reabsorption in the kidney as well as causing smooth muscle contraction in blood vessels increasing blood pressure. Less angiotensin II activating vasopressin release inhibits blood pressure from increasing. Overall, Moexipril inhibits the conversion of angiotensin I into angiotensin II, a powerful vasoconstrictor and mediator of high blood pressure so decreasing levels of angiotensin will help reduce blood pressure from climbing in individuals.

Moexipril (trade name: Univasc) belongs to the class of drugs known as angiotensin-converting enzyme (ACE) inhibitors and is used primarily to lower high blood pressure (hypertension). This drug can also be used in the treatment of congestive heart failure and type II diabetes. Moexipril is a prodrug which, following oral administration, undergoes biotransformation in vivo into its active form moexiprilat via cleavage of its ester group by the liver. Angiotensin-converting enzyme (ACE) is a component of the body's renin–angiotensin–aldosterone system (RAAS) and cleaves inactive angiotensin I into the active vasoconstrictor angiotensin II. ACE (or kininase II) also degrades the potent vasodilator bradykinin. Consequently, ACE inhibitors decrease angiotensin II concentrations and increase bradykinin concentrations resulting in blood vessel dilation and thereby lowering blood pressure.
