Correct Answer is C

Explanation

Choice A rationale

Antagonistic reactions occur when one drug interferes with the action of another, decreasing its effectiveness. This is not applicable in this case as aspirin and alcohol together increase the risk of bleeding rather than opposing each other's actions.

Choice B rationale

Synergistic reactions happen when two drugs enhance each other's effects. Aspirin and alcohol together can indeed increase the risk of gastrointestinal bleeding, but this is not referred to as a synergistic reaction.

Choice C rationale

Additive reactions occur when two drugs with similar effects add up to a greater effect. Aspirin and alcohol both increase the risk of bleeding, and their combined effect leads to gastrointestinal bleeding.

Choice D rationale

Neutral reactions imply that the drugs do not interact and have no combined effect, which is incorrect here as the combination of aspirin and alcohol leads to an increased risk of GI bleeding.

A. Tamsulosin (Flomax). B. Sildenafil (Viagra). C. Ethinyl estradiol and drospirenone (Yasmin). D. Finasteride (Proscar).

Correct Answer is ["B","C"]

Explanation

Choice A rationale

Tamsulosin is used to relax the muscles in the prostate and bladder neck, making it easier to urinate in men with BPH.

Choice B rationale

Sildenafil is primarily used to treat erectile dysfunction and pulmonary hypertension. It is not used to treat BPH.

Choice C rationale

Ethinyl estradiol and drospirenone are components of oral contraceptives and are not used for the treatment of BPH.

Choice D rationale

Finasteride is used to shrink an enlarged prostate by blocking the hormone that causes prostate growth, making it a common treatment for BPH.
