Agouron is planning to conduct a study of rifabutin which has similar, but generally less potent p inducing powers as rifampin. Alternative MAI prophylaxis regimens are suggested until results of the rifabutin study are known. Preliminary trough level measurements suggest that only minor increases in nelfinavir concentrations may occur during treatment with ketoconazole.

Based on these preliminary results, dose modification should not be required. Preliminary study in animals find that saquinavir blood levels increase fold when combined with nelfinavir. At the nevirapine FDA hearing last week, concerns were raised about nevirapine's interactions with protease inhibitors.

Boehringer Ingelheim, the developer of nevirapine listed indinavir, ritonavir, saquinavir -- but not nelfinavir -- as the drugs they will study for potential interaction. Recently, all the protease inhibitor developers have been discussing studying further the combination of two protease inhibitors in one therapy. Ergostat, Cafergot, Ercaf, Wigraine ergotamine or D. Hismanal astemizole or Seldane terfenadine Cholesterol-lowering drugs statins: Zocor simvastatin and Mevacor lovastatin Antipsychotics: It might be necessary to increase your dose of Viracept if you are taking any of these drugs.

We know that Norvir ritonavir increases the amount of Viracept in the bloodstream the recommended dose is two or three mg Viracept tablets combined with four mg Norvir capsules. Viracept increases Agenerase amprenavir and Lexiva fosamprenavir levels in the bloodstream no dose has been recommended. When Viracept is combined with Invirase saquinavir , blood levels of both drugs are increased the dose of Invirase should be mg twice daily and the dose of Viracept should be mg twice daily, with no Norvir added.

Viracept also increases Crixivan indinavir levels, but no dose has been confirmed. Sustiva efavirenz , Viramune nevirapine , and Rescriptor delavirdine can all increase Viracept levels in the bloodstream, although it's probably not necessary to change the doses. Rifadin rifampin can decrease Viracept levels in the bloodstream; these two drugs should not be used together.

Viracept can increase Mycobutin rifabutin levels and Mycobutin can decrease Viracept levels the Mycobutin dose should be reduced to mg every day and the Viracept dose should be increased to four mg tablets three times a day. It is not known if Viracept effects Biaxin clarithromycin levels in the bloodstream. The recommended dose of nelfinavir is mg 5 tablets twice a day or mg 3 tablets 3 times a day. Nelfinavir must be taken with a meal or light snack. In clinical study, nelfinavir was administered with meals containing to calories, of which to calories were derived from fat.

Nelfinavir tablets should be stored in a closed container and kept at a temperature of 59 [degrees] to 86 [degrees] F and protected from moisture. Do not heat the mixed dose once it has been prepared. Do not mix the powder with any acidic food or juice, such as orange or grapefruit juice, apple juice, or apple sauce, because this may create a bitter taste. Do not add water to bottles of oral powder. For help in determining the exact dose of powder for your child, please ask your doctor, nurse, pharmacist, or other healthcare provider.

What should I do if I miss a dose? However, if you skip the dose entirely, do not double the next dose. If you forget a lot of doses, talk to your healthcare provider about how you should continue taking your medicine. If you suspect that you took more than the prescribed dose of this medicine, contact your local poison control center or emergency room immediately.

These could cause serious side effects that could cause death. These include prescription and non-prescription medicines and herbal supplements. Also tell your healthcare provider if you have any known allergies to other medicines, foods, preservatives, or dyes.

Tell your healthcare provider if you are pregnant or plan to become pregnant. If you are breast-feeding, it is very important that you speak with your healthcare provider about the best way to feed your baby. If your baby does not already have HIV, there is a chance that it can be transmitted through breast-feeding.

Talk with your healthcare provider if you have liver or kidney disease. The hot melt granulation process of the present invention comprises blending the nelfinavir mesylate and the copolymer, and heating the blend to a temperature of from the copolymer melting point temperature to below the decomposition temperature of nelfinavir mesylate.

The hot melt granulation process results in a melt granulation which comprises granules of the drug embedded in the copolymer. The heated blend is mixed until such melt granules are obtained. Preferably, the blend is heated to a temperature at which the nelfinavir mesylate remains in solid form in the nelfinavir mesylate-copolymer mixture. A jacketed mixer or a hot melt extruder can be used to prepare a melt granulation.

One or more excipients can be included in the mixture of nelfinavir mesylate and copolymer. The excipient can be selected from the group of stabilizers, wetting agents, binders, disintegrants, diluents and solubilizers. Examples of additives for inclusion in the nelfinavir mesylate-copolymer mixture are povidone, polyethylene glycol, and polyoxyethylene sorbitan esters of C8-C18 fatty acids, e.

The heated blend is mixed and melt granules are formed, thus resulting in a melt granulation that includes one or more pharmaceutically acceptable excipients. The melt granulation can then be milled and mixed with one or more pharmaceutical excipients.

The excipient added to the milled granulation can be selected from the group of lubricants, disintegrants and diluents. The pharmaceutical excipient may be, for example, microcrystalline cellulose, corn starch, magnesium stearate, etc. The melt granulation, prepared with or without any additional pharmaceutical excipients, is then processed into a solid unit oral dosage form. For preparing tablets, the melt granulation can be processed into a solid unit oral dosage form by milling, lubricating, compressing tabletting , and, typically, aqueous film coating.

In an embodiment of the present invention, tablets are prepared as follows: A pharmaceutical dosage form of the invention, can alternatively be prepared by hot melt extrusion. Hot melt extrusion can be used to make molded tablets. The solid oral unit dosage form can be a tablet, capsule or caplet.
