43. Furosemide is commercially available as a:

Answer: A

Explanation:

Furosemide is commercially available as a 20 mg tablet.

Furosemide is primarily available in a 20 mg tablet form, which is commonly prescribed for treating conditions such as edema and hypertension.

A) 20 mg tablet

This option is correct as furosemide is indeed commercially available as a 20 mg tablet. This formulation is widely used in clinical practice for its efficacy in diuresis.

B) 30 mg tablet

This option is incorrect because furosemide is not typically available in a 30 mg tablet form. The standard dosages are usually lower or higher than this specific amount, with 20 mg being a common formulation.

C) 20 mg suppository

This option is incorrect as furosemide is not available in a suppository form. The medication is predominantly provided in oral and injectable forms, but not as a suppository.

D) 30 mg suppository

This option is also incorrect for the same reason as option C. Furosemide does not come in a suppository form, and the available formulations do not include a 30 mg suppository.

Conclusion

The correct answer is clearly option A, as furosemide is commercially available in a 20 mg tablet form, which is a standard dosage prescribed for various medical conditions. All other options fail because they either suggest incorrect formulations or dosages that are not available.
