Final answer:
To fulfill the prescription of Prozac at 60 mg per day for thirty days with 20 mg tablets, 90 tablets need to be dispensed. Prozac is a Selective Serotonin Reuptake Inhibitor that increases serotonin levels and is used in the treatment of depression.
Step-by-step explanation:
The question pertains to the calculation of the number of tablets needed when a physician prescribes a specific daily dosage of Prozac. Prozac (fluoxetine) tablets are available in 20 mg doses. The prescription is for 60 mg per day for a duration of thirty days. To calculate the number of tablets needed, one must divide the daily prescribed dosage by the dosage of each tablet. Therefore, 60 mg/day divided by 20 mg/tablet equals 3 tablets per day. Over the course of thirty days, this would result in a total of 90 tablets required to meet the patient's needs. This calculation ensures that the patient has an adequate supply of medication, as prescribed by the healthcare provider.
Prozac is a type of Selective Serotonin Reuptake Inhibitor (SSRI), which helps to treat depression by increasing the levels of serotonin in the central nervous system. It is considered an agonist for serotonin since it promotes the action of serotonin at the synapse. Prozac is one of several SSRIs, which also include medications such as sertraline (Zoloft) and paroxetine (Paxil).
