HCI at the end of a drug name means hydrochloride.
Hydrochloride is a salt of hydrochloric acid that is used as a vehicle for drug administration which makes the drug more soluble as well as easier to absorb.
Hydrochloric acid or HCI is a strong acid which, when combined with an organic base, forms a hydrochloride salt.
Many drugs including prescription drugs and some over the counter drugs as well as some street drugs also contain hydrochloride.
Hydrochlorides are used for administering drugs because they are more soluble in water than the free base form of the drug.
Examples of medications that contain hydrochloride salts are bupropion hydrochloride, oxycodone hydrochloride and metformin hydrochloride.
The drugs that contain hydrochloride is absorbed more quickly and efficiently into your bloodstream and allows the drug or medication to work faster and more effectively.
CD on a prescription means controlled delivery.
On some drugs the CD may also mean controlled drugs but for most other medications, the CD means controlled delivery.
TR on a prescription means time release and LA on a prescription means long acting.
A controlled delivery medication is a medication that releases the correct dose of the drug directly into the desired zone and during the required period of time which allows for maximizing the efficacy of the therapeutic and minimizing any possible side effects.
ER on a prescription means that the prescription medication is extended release.
Extended release medications are designed to last longer in the body.
As a result of the extended release the medication last longer and allows you to take the medication less often when compared to the IR version of the medication.
With an ER or Extended Release medication you may only need to take 1 to 2 doses of the medication a day when compared to the possible 3 to 4 doses of the medication in IR version.
IR on a prescription means immediate release which means that the medication is immediately released in your body and does not stay as long in the body so you may need to take more of the medication when compared to extended release medication.
The standard dosage form of most oral medication is the IR or immediate release version.
So if your medication says IR it means it's immediate release and if your medication says ER or XR it means that the medication is a longer acting extended release medication.
Immediate release medications are not as long acting as extended release medications are.
