Select a Dose. ZUBSOLV is contraindicated in patients with a history of hypersensitivity to buprenorphine or naloxone, as serious adverse reactions, including anaphylactic shock, have been reported. Addiction, Abuse, and Misuse: Buprenorphine can be abused in a similar manner to other opioids. Monitor patients for conditions indicative of diversion or progression of opioid dependence and addictive behaviors. Multiple refills should not be prescribed early in treatment or without appropriate patient follow-up visits.

Respiratory Depression: Life-threatening respiratory depression and death have occurred in association with buprenorphine use.

Buprenorphine can cause severe, possibly fatal respiratory depression in children. Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patients off of the opioid.

Risk of Opioid Withdrawal with Abrupt Discontinuation: If treatment is temporarily interrupted or discontinued, monitor patients for withdrawal and treat appropriately. Risk of Hepatitis; Hepatic Events: Monitor liver function tests prior to initiation and during treatment and evaluate suspected hepatic events.

Precipitation of Opioid Withdrawal Signs and Symptoms: An opioid withdrawal syndrome is likely to occur with parenteral misuse of ZUBSOLV by individuals physically dependent on full opioid agonists or by sublingual administration before the agonist effects of other opioids have subsided. Geriatric Patients: Monitor for sedation and respiratory depression. Adverse events commonly observed with the sublingual administration of ZUBSOLV are headache, nausea, vomiting, hyperhidrosis, constipation, signs and symptoms of withdrawal, insomnia, pain, and peripheral edema.

Antiretrovirals: Patients who are on chronic buprenorphine treatment should have their dose monitored if NNRTIs are added to their treatment regimen. Monitor patients taking buprenorphine and atazanavir with and without ritonavir, and reduce dose of buprenorphine if warranted.

Serotonergic Drugs: Concomitant use may result in serotonin syndrome. Please see full Prescribing Information for a complete list.

Interspecies allometric scaling for dose conversion from animal to human studies is one of the most controversial areas in clinical pharmacology. Allometric approach considers the differences in body surface area, which is associated with animal weight while extrapolating the doses of therapeutic agents among the species. This review provides basic information about translation of doses between species and estimation of starting dose for clinical trials using allometric scaling.

The method of calculation of injection volume for parenteral formulation based on human equivalent dose is also briefed. Safe and effective drug dosing is necessary, regardless of its purpose of administration. There are several instances, wherein the initial dose of a particular drug is unavailable in a specific species. Therefore, choosing starting dose of such drugs for research, experiments, or clinical trials in animals and humans is a concern.

This is primarily because the biochemical, functional systems in species vary which in turn alter pharmacokinetics. Therefore, extrapolation of dose from animals to humans needs consideration of body surface area, pharmacokinetics, and physiological time to increase clinical trial safety. There are four different methods namely dose by factor, similar drug, pharmacokinetically guided, and comparative approaches are described in literature to assess the initial dose. In similar drug approach, the existing pharmacokinetics data for another drug of the same pharmacological category may be used.

Allometric scaling is an empirical approach where the exchange of drug dose is based on normalization of dose to body surface area. Drugs with lesser hepatic metabolism, low volume of distribution, and excreted by renal route are ideal candidates for scaling of dose by this approach.

Typically, MRSD is calculated from preclinical toxicology studies and applying a factor. NOAEL, the highest dose level that does not cause significant adverse effects, is a typical index for safety obtained from proper animal experiments to determine a safe starting dose. The next step is selection of most appropriate species to use in calculation of MRSD. In general, animal species with the lowest HED is considered most sensitive species for determining human risk and is usually selected.

On the other hand, a specific animal that is more sensitive toward adverse effect can also be a suitable species. In step 4, the HED is divided by a factor value of 10, to increase safety of first human dose. This safety factor is accountable for differences in physiological and biological processes between human and animal species.

In the final step, the value obtained is converted to pharmacologically active dose in humans. The dose by factor method applies an exponent for body surface area 0. Thus, HED is determined by the equation:. To calculate the starting dose for human studies, use Equation 1.In the actual NCLEXthese type of dosage calculations are usually formatted as a fill-in the blank question type.

Make sure to take a look at our ibuprofen dosage calculator and the paracetamol dosage calculator! Depending on the route of administration, dosage forms come in several different types. The most popular route of administration is oral, however, in some medical situations this route is unavailable, ineffective or associated with a high number of adverse reactions.

That is why patients may receive drugs through parenteral means this includes: subcutaneous, intramuscular, intraosseous, intravenous, etc. Moreover, some drugs are only given topically - they're applied directly onto the skin or eye, into the rectum or vagina, or as an inhalation. You should know that the route of administration of a drug dramatically influences its dosage and efficacy.

You should thus always check if you are administering the appropriate drug to the appropriate person through the appropriate route in the appropriate dose! When treating a patient, or just taking a medication by yourself, we always need to wonder what is the exact dose of the drug we choose. And the truth is that we dose or should dose nearly everything in our life, from cooking dinner to taking medications!

This calculator should be used as a reference for oral benzodiazepine conversions. Equipotent benzodiazepine doses are reported as ranges due to paucity of literature supporting exact conversions, thus reported ranges are based on expert opinion and clinical experience published in psychiatric literature. This calculator does not account for age, organ function, and inter-patient variability that may alter the pharmacokinetics, peak effect, and duration of action.

Selecting doses on the lower end of the reported range may result in lower risk of unwanted oversedation. Dosing conversions may not be adequate when treating such conditions as status epilepticus or alcohol withdrawal. Disease-state specific guidelines should be utilized. Please fill out required fields. Abrupt discontinuation of benzodiazepines should be avoided as this can precipitate withdrawal symptoms, including severe agitation and seizure activity.
