Api rate pseudoephedrine hcl?

I’m not sure what you mean by “Api rate pseudoephedrine hcl.” The phrase could refer to very different things (API = active pharmaceutical ingredient, “rate” = dosage/strength or regulatory rate/limit, and pseudoephedrine HCl = the drug substance).

To answer accurately, tell me which one you’re asking about:

1) What’s the API strength/dosage rate of pseudoephedrine HCl in a product (e.g., tablets/syrup)?
2) What are the legal limits/regulated “rate” for pseudoephedrine HCl sales or transactions (e.g., daily/weekly limits)?
3) Are you asking about API production or batch “rate” (manufacturing throughput/specs)?
4) Are you looking for lab/API specs (purity, particle size, assay, CAS, grade)?

If you paste the exact context (a label, a sentence from a document, country/state, and whether you mean “rate” as dosage vs legal limit), I can give a precise answer.
