Which of the following best describes a controlled experiment?  

Match the following drugs with the mechanisms of action. Each drug may be used more than once or not at all:

The efficacy of oral contraceptives and progestin implants may be reduced by the  following drug:                                                                             1.                           Dolutegravir2.                           Efavirenz3.                           Oseltamivir4.                           Acyclovir5.                           Valacyclovir

The following antiviral drug classes are associated with increased risk of abnormal lipid profile:                                                                                                                                                                                                  1.          Protease inhibitors 2.          Neuraminidase inhibitors3.          Viral DNA polymerase inhibitors4.          Integrase strand transfer inhibitors 5.          Entry blockers

 40.    The following drug is a selective inhibitor of the neuraminidase of influenza A and B  viruses:                                                                                                                                        TenofovirRitonavirOseltamivirAcyclovirEmtricitabine

Folic acid may decrease the efficacy of the following agent during toxoplasmosis  treatment:                                                                                                                           1.        Azithromycin2.        Folinic acid3.        Clindamycin4.        Pyrimethamine5.        Suramin

As drowsiness may occur during treatment, patients should be warned not to drive or operate machinery while on the following drug:                                                             AlbendazoleDoxycyclineIvermectinArtemether/lumefantrineBenzyl benzoate

Praziquantel is indicated for:                                                                       1.        Scabies2.        Onchocerciasis3.        Babesiosis4.        Cysticercosis5.        Priapism

The following drug is indicated for the treatment of cytomegalovirus:                                                   1.        Lamivudine2.        Oseltamivir 3.        Ribavirin4.        Ganciclovir5.        Darunavir

The following is the mechanism of action of proguanil:                                                            1.        It inhibits the detoxification of the heme in the erythrocyte2.        Its metabolites produce reactive oxygen species which are fatal to the malaria parasite3.        Its metabolites inhibit nucleic acid synthesis by oxidizing plasmodial DNA4.Inhibits plasmodial protein synthesis by binding to 30S ribosomal subunits5.        It inhibits plasmodial dihydrofolate reductase enzyme action
