47. Which route of administration is appropriate for Lovenox?

Answer: D

Explanation:

Subcutaneous administration is appropriate for Lovenox.

Lovenox, a low molecular weight heparin, is typically administered via the subcutaneous route due to its pharmacokinetic properties, which allow for effective absorption when injected into the fatty tissue.

A) Rectal

Rectal administration is not appropriate for Lovenox as it is not designed for absorption through the rectal mucosa. This route would also lead to unpredictable bioavailability and is not typically used for anticoagulants.

B) Sublingual

Sublingual administration is incorrect for Lovenox because this route is primarily used for medications that can be absorbed quickly through the mucous membranes under the tongue. Lovenox requires subcutaneous delivery to ensure proper absorption and therapeutic effect.

C) Oral

Oral administration is not suitable for Lovenox since it would be subject to first-pass metabolism, greatly reducing its efficacy. Lovenox is specifically formulated for injection, which bypasses the gastrointestinal tract.

D) Subcutaneous

Subcutaneous administration is the correct route for Lovenox as it allows for the medication to be absorbed directly into the bloodstream without the complications associated with oral or other non-injection routes. This method provides reliable anticoagulation.

Conclusion

Subcutaneous administration is the only appropriate route for Lovenox, ensuring optimal absorption and therapeutic efficacy. The other options—rectal, sublingual, and oral—are unsuitable and would compromise the drug's effectiveness due to various pharmacokinetic limitations.
