CERT-Based Explanations

Norethindrone (Antifertility Drug):

Norethindrone is a synthetic progesterone derivative.

Birth control pills generally contain mixtures of synthetic estrogen and progesterone derivatives.

$$\mathrm{Norethindrone}$$ is one of the commonly used antifertility drugs.

Salvarsan (Antibiotic):

Salvarsan, also known as arsphenamine, was developed by Paul Ehrlich as the first effective treatment for syphilis.

It was an important milestone in antibacterial therapy.

$$\mathrm{Salvarsan}$$ is therefore classified as an antibiotic.

Meprobamate (Tranquilizer):

Tranquilizers are neurologically active drugs used in the treatment of stress and mental disorders.

$$\mathrm{Meprobamate}$$ is a mild tranquilizer used to relieve tension and anxiety.

Alitame (Artificial Sweetener):

$$\mathrm{Alitame}$$ is a high-potency artificial sweetener.

It is nearly $$2000$$ times sweeter than cane sugar and is more stable than aspartame.
