What does the shelf life of a drug mean?
Answers:
It means that the active ingedient in the drug hasn't been tested for efficacy beyond that point, or that testing has shown reduced efficacy beyond that point. In most cases the reason is the former, not the latter. Meaning that after the specified date the drug may be less effective than advertised, thereby requiring labeling showing known shelf life.In other words, if you have 500mg tablets of Prilosec (The Purple Pill) with an expiration date of March 1, 2007, that means that the drug has been tested to be effective as advertised from the time the process on that particular batch was complete until the expiration date.Consumption AFTER the expiration date doesn't indicate that the drug will have adverse effects. It indicates that the effects may be reduced.
Means that beyond that date you should not consume the drug.
Same as the date on a carton of milk.
It is guaranteed fresh %26 good until that date.
How long the drug will last till it goes bad and non-edible.
it is the length of time a drug is safe to consume. but it differs from expiry date. the shelf life means the quality is optimal and beyond that it is still safe to consume but quality is no longer guaranteed.
the shelf life of a drug is the span of time when the drug is still effective and can be administered without any side effects
I am a med lab technologist and patient care technician, I also have my home nursing degree, the expiry date is just that.it has expired.it wont kill you if you take it, beyong popular belief, pills do not go bad or get spoiled.it just loses its potency. The effectiveness of the drug is not guarenteed after that date.
it's the expiration date. it can only be on the shelf for a certain amount of time before the potency goes down
Shelf life of a drug product is defined as the length of time, under the specific storage conditions, the drug product remains within specifications established to ensure its identity, purity, quality, and strength.
Let me give you an example. I don't know that you would consider hydrogen peroxide a legit "drug", but you may use it like a topical drug. Hydrogen peroxide has a half life. After a few years, any bottle of proxide solution will turn into a bottle of water (plus oxygen, which would probably slowly leak out.). Any drug you come across may have similar half lifes.. (although I can't say for certain what they would be, I'm not a chemist). Some drugs have a much longer storage life than others. I think asprin has an incredibly long shelf life. But the second factor is time itself. Some drugs are sensitive to moisture In the case of hydrogen peroxide, Ultraviolet exposure. The chances that any particular drug may have had something happen to it increase over time, therefore the likelyhood that any one pill will be as effective as when it was originally bought is deminished.Finally, drugmakers would like turnover, so its rather profitable for them to set limited shelf lifes. Please note: Antibiotics are netoriously short in shelf life. If you have old antibiotic ointments lying around, get rid of them because they won't do you any good.
Shelf life is just that.It is the amount of time the store can keep it on the shelf.It loses some of its potential after that.
what does the RX on doctors prescription mean??
on doctors prescriptions there is always an RX sign at the beginning of the 1st line, u can c tis sign also in pharmacies, what does it mean, or what does it stands for??
Answers:
The simple, quick answer--but not the only (or most romantic) one--is that Rx is an abbreviation for the Latin word "recipere" or "recipe," which means "Take, thou."
The symbol "Rx" meaning "prescription" is a transliteration of a symbol resembling a capital R with a cross on the diagonal (鈩?.There are various theories about the origin of this symbol - some note its similarity to the Eye of Horus, others to the ancient symbol for Jupiter, both gods whose protection may have been sought in medical contexts. Alternatively, it may be intended as an abbreviation of the Latin "recipe", the imperative form of "recipere", "to take"[2], and it is quite possible that more than one of these factors influenced its form. Literally, "Recipe" means simply "Take.." and when a doctor writes a prescription beginning with "Rx", he or she is completing the command. This was probably originally directed at the pharmacist who needed to take a certain amount of each ingredient to compound the medicine, rather than at the patient who must "take" the medicine, in the sense of consuming it.
Prescription
Rx means exactly that, prescription.Rx - is a short form of some word in Latin, I think.

"鈩?quot; (also written as "Rx") and "medical prescription" are sometimes used interchangeably. The use of 鈩?in prescriptions originated as an astrological symbol that was written for talismanic reasons at the start of medical prescriptions. Later it changed into 鈩?(an uppercase R with its tail crossed), and was used as an abbreviation for the Latin word recipe = "take" (imperative), i.e. an instruction to the pharmacist to take the items listed in order to prepare the medicine. When printing came, it was rendered as "Rx"
Rx or legend drug is a legal description in the United States for drugs that are only available on prescription from a licensed medical practitioner but are not controlled substances.

what does the nervous system need most to function properly? fats, carbs.?
Answers:
It needs protein and the right types of fatty acids (eg Omega 3 types), in abundance, to form properly. It mostly uses simple sugars as fuel (eg glucose), AFAIK.Cats need taurine to develop their brains, BTW. It is an amino acid, but is not one of the 20 normally used to build proteins.
It normally functions on glucose, but it LOVES ketones. Also fats are important for myelinization.

What does the HCl that is included in many medication names refer to?
Answers:
I know HCL as hydrochloric acid. However, I do not know any medication that makes use of HCL. Perhaps you could tell me the name of your medicine? (My guess is that those are orally ingested HCL tablets) HCL is actually found in the stomach and has a pH value of 2: highly acidic and corrosive. HCL activates the zymogens, pepsinogen and prorennin into pepsin and rennin. Besides, I have an interesting fact for you. Your stomach digests only PROTEINS. NO other stuff. Interesting it is right? Such a bag digests only protein!Zymogens are inactivated enzymes.
Enzymes help to digest food at a faster rate
Inactive enzymes cannot digest food
H = hydrogen
Cl = chloride
together they = hydrochloric acid
HCl is actually the short name or formula for hydrochloric acid.
first of all, HCl is not included in medications at the finished product, I mean its acidic effects does not exist, but its relative to its salt component, such as drug-HCl, because salts of HCl are easily dissolved in the media of stomach and intestine. so Drug-HCl is only means that itis the salt of medication, the cl is negative and the medication is positively charged in an acqeous solution.
HCL= [H] Hydrogen [CL] Chlorine.Combined HCL is pronounced
hydrochloric acid which of course is an acid.It is a amolecule having one atom of hydrogen and one atom of chlorine.When in a drug its acidic properties are next to nil.The HCl is present to make the drug soluble in water and digestive juices.
You ROCK Mr Pharm D Jtvone !Hydrochloride
The chemical compound hydrochloric acid is the aqueous (water-based) solution of hydrogen chloride (HCl) gas. It is a strong acid, the major component of gastric acid and of wide industrial use. As a highly corrosive liquid, hydrochloric acid should be handled only with appropriate safety precautions.Hydrochloric acid, or muriatic acid by its historical but still occasionally used name, has been an important and frequently-used chemical from early history, and was discovered by the alchemist Jabir ibn Hayyan around the year 800. It was used throughout the Middle Ages by alchemists in the quest for the philosopher's stone, and later by several European scientists including Glauber, Priestley, and Davy, to help establish modern chemical knowledge.During the Industrial Revolution, it became an important industrial chemical for many applications, including the large-scale production of organic compounds, such as vinyl chloride for PVC plastic and MDI/TDI for polyurethane, and smaller-scale applications, such as production of gelatin and other ingredients in food, and leather processing. At present, production is approximately 20 million metric tonnes annually (20 Mt/a) of HCl gas.
what does the expiration date on drugs mean?
specifically i have ibuprofen with an expiration date of february 05. does the drug mutate into something harmful or does it just lose potency? if it is just a decrease in potency what would the current potency be as a percentage of the full strength?
Answers:
It really depends. For most drugs, the expiration date is not the actual "expiration" date, that is, the drug loses its potentcy/kills you, but the date you should discard it while you remember. As a matter of fact, most of the expired drugs, sometimes for years, are being donated by medical corporations to third world countries and a great majority of them are still effective. HOWEVER, this does not encourage you to take expired medicine. Depending on the drug you are having, it could be deadly. So to answer your question, don't try expired medicine unless you are in Africa (Yes, I know it sounds messed up).
It probably just loses potency. But be careful. Your body might have a crazy reaction to it. I took expired pills once thinking they'll still work. My body rejected it and I threw up. EWW! Gross!
The drugs were lab tested and their effective potency can be assured under normal storage conditions until the expiration date. Ibuprofen is inexpensive, take what you need for pain now (keep it under 800mg) and go get a new bottle.
With scripts it's the toss date, but over-the-counter drugs which are just a fraction of the potency; I usually keep another six months.
an expiration date on drugs mean they are no good. They are no longer in service to smoke. Don't smoke them, you can get really sick from it!
Expiration date on drugs means that after that date, it will START to decrease its potency until such time that the drug will lose its efficacy. AFTER that, it will start to become a harmful substance.Therefore, if possible, refrain from using expired drugs because you might not get the correct dosage that you need and it might even be harmful to your health.
The expiry date of drugs are the date when drugs start to rot..
It means the drug will probably not be as effective because the ingrediants have started to break down. Taking them could give you a reaction. It is possible that nothing else could happen because the drugs simply have lost their effectiveness.
