Abstract

The present invention relates to the process of preparing a stable fixed dose composition of anti-infective agent with micro organism as active ingredients. The process includes preparation of various dosage forms for oral route like capsule, tablet and liquid formulation. The process comprises providing an appropriate barrier by way of selected coating procedure to one of the active ingredients in such a way that micro organisms are not affected by anti-infective agetns. This results in a stable composition. The ratio of micro organism to anti-infective agents in a composition can be 1:2 to 1:25 by weight. The amount of coating is dependent on the type of coating technique, dosage form i.e. capsule, tablet or liquid and desired self life. The compositions eliminate gastro intestinal disturbances associated with anti-infective agents. The anti-infective agent may be ampicillin, amoxycillin, cloxacillin cephalexin, cefuroxime or cefixime and the micro organism is preferably a Lacto bacillus.

Description

The present invention relates to a process of manufacturing a formulation containing antiinfective agent(s) with viable organisms which are susceptible to anti-infective agents. Micro organisms are used to prevent adverse effects like diarrhoea caused by anti-intective agents.
The present invention is directed to manufacturing of a formulation where in anti-infective agents and susceptible viable organisms are combined in such a way so that micro organisms, through susceptible to anti-infective agent, remain viable for the self life of a formulation and/or till they are consumed. Susceptible organisms are usually combined with antiinfective agents to prevent or minimise adverse elects of anti-infective agents like diarrhoea, pseudomembranous colitis, mega colon, etc.
Organisms are classified as pathogens and commonsals. Pathogens are responsible for various infectious diseases and are not normally present in that part of the body. They are also known as infectious agents. Commonsals are normally present in various parts of body and perform useful functions. They provide vitamin K, B-12, Thiamine, Riboflavin etc. to body. They iiihibit the growth of pathogens by variety of mechanisms. Anti-infective agents are used to treat/prevent infectious diseases. They kill organisms by various ways. however they are not always specific @@@ patl0ogens and also kill commonsals. Destruction or reduction in number of commonsals results ill loss of function of commonsals and various effects of these are seen.2'5 These effects are known as adverse effects or side effects of antiinfective therapy. Diarrhoea with or without super-infection is one of such effecis seen with anti-infective therapy.3.4.6 Diarrhoea is seen as an adverse reaction to many antibiotics. But they are most commonly seen with broad spectrum antibiotics. The incidence of diarrhoea also depends on level of absorption from G.I. tract. They are less frequent with those getting completely absorbed compared to incompletely absorbed. They also depend on anlount of drug used. The antibiotics causing diarrhoea include clindamycin, ampicillin, amoxycillin, cephalosporins (e.g. cefuroxime axetil, cefixime, cepahiexin ceftriaxone), amoxycillin + clauvanic acid, ampicillin + salbeutam, fluoroquinolens and other combinations of broad spectrum antibiotics, e.g. amoxycillin + cloxacillin. 3.5.6.7.8.9.10.11.12.13.16.18 Diarrhoea can be benign and secondary to transient dysfunction of normal colonic flora due to anti-infective agents6 or super-infection by pathogens like clostridium difficile following alteration of normal flora by anti-ineffective agents.7.4.19.20 Management in such an event requires cessation of anti-infective therapy3.7.4 and use of other therapies. Other therapies which can be used include different kind of anti-infective agents e.g. metronidazole, vancomycin, 3.13.8 teicoplanin and/or use of organisms like lactobacilli, biofidobacterium. saccharomyies boulardili, streptococcus thermophilus, enterococcus facecium SF 68, L Casei GG etc.14.15.16 These can be combined with whole bowel irrigation with good results.'7 Organisms used9 eradicate or help in eradicating pathogens by variety of mechanisms which include production of hydrogen peroxide or inhibition or adherence of pathogens to intestinal cells. Anti-infective agents induced diarrhoea prolong treatment, increase cost of therapy by increased number of' drugs to be used.2 days of hospitalisation and 3consultations.
Sometimes they create life threatening situation e.g. pseudememberous colitis,4.13.20 toxic megacolon.
The organisms named above can be used 10 treat diarrhoea when it occurs. They can also be used to prevent diarrhoea.14.16.18 Commercially available preparations include lactobacillus alone (Lactiflora, Lactobacil, Lactocap, Lactovit, Sporlac) or in' combination with streptococcus (Lacticyn) or Sacchromyces (Laviest). To prevent diarrhoea organisms are given along with the anti-infective agents. This requires consumption of minimum two different drugs i.e. an anti-infective agent and an organism. This decreases compliance of à patient.
Attempts have been made to put organisms and an anti-infective agents into one formulation.
Some of these ore commercially available. Lactobacillus is commonly used organism. Antiinfective agents used in the formulation include ampicillin, (e.g. Alcillin plus from Alpine), amoxicycillin (e.g. Alox plus from Alpine), ampicillin + cloxacillin (e.g. Amplus from Jagsonpal, Elclox plus from Elder, Penmix plus from Dee Pharma, Pen plus from Systopic, Poxin Plus from Alpine), amoxicycillin + cloxacillin (e.g. Bicidal plus from Kee Pharma, Diclox from Croford Pharma, Twinclox plus from Alpine). They all are simple admixture of anti-infective agents and susceptible organisms. Ilowever, analysis of' cononoercially available, as well as prepared by us revealed that organisms incorporated into formulation does not remain viable and did not perform any useful function for which they were to be used. Neither organisms nor their activity could be detected as early as 7 days after putting lactobacilli with various antibiotics like ampicillin, amoxycillin, amoxycillin + cloxacillin etc. or in commercially available preparation. Through 60 million spores are put into formulation, none of them could be grown or demonstrated viable on glucose yeast extract agar plate. It also failed to produce lactic acid as evaluated by consumption of NaOH.

The further objective of present invention is to minimise side effects of anti-infective agents resulting from destruction/alteration of normal flora by provising viable organisms along with anti-infective agent(s).
The further objective of present invention is to provide a pharmaceutical composition which is effective after longer period of storage.
The further objective of this present invention is to increase compliance by reduction / elimination in side effects of anti-infective agents.
The turther objective of the present invention is to improve compliance by providing two drugs in one pharmaceutical composition.
The further objective of present invention is to provide at a desired site.
The following specification particularly describes and ascertain the nature of this invention and manner in which it is to be performed.
The anti-infective agent and organisms are to be identified. Their dosage route of administration and dosage fornl is finalised.
The susceptible organism are combined into the formulation in such a way that organisms remain viable for the self life of a formulation inspite of being in contact with anti-infective agent. To protect susceptible organisms from effect of anti-infective agent a protective barrier is created around organisins or anti-infective agent, in such a way that anti-infective agent cannot have effect on oräanisnos. This results in viable organisms in presence of antiinfective agent. The organism remain viable as long as the barrier is maintained. This is like applying paint or a film on a substance to prevent corrosion by isolating it from surroundings.
The protective barrier is selected depending on route ot' administration and dosage form of the pharmaceutical composition (anti-infective agent + organism) The pharmaceutical composition so manufactured is evaluated for stability and efficacy.
The pharmaceutical composition so manufactured is evaluated at different test conditions of temperature and humidity (45"C, 37"C at 80% relative humidity and ambient temperature) for time interval extending upto 12 months.
The samples of formulation were taken for study at 3 weeks intervals. Samples were analysed for presence of organisms by quantitative and qualitative microbiological techniques.
These values were found to be comparable with amount of organisms introduced into formulation.
The samples ol formulation were also analysed for presence of anti-infective agent by quantitative estimation. The values of anti-infective agents forms wwere found to be comparable to those introduced into the formulation.
Thus findings indicate presence of organism and anti-infective agent in same amount when formulation was evaluated at different time interval after it was exposed to different environment.
The formulations so created were wound to have improved therapeutic efficacy in term of reduction/elimination of antibiotic induced diarrhoea.
Usually ampicillin causes maximum diarrhoea amongst penicillin. The reported incidence is as high as 20% with ampicillins. In 40 patients when ampicillin + lactobacilli were given in a pharmaceutical composition prepared as described in this application, none of them developed diarrhoea and everybody could complete the full course of antibiotic therapy.

2. Following are examples of providing barrier to organisms for different dosage forms.
1-lowever, it is not intended that the scope of this invention be limited by these examples.
Example 1 Capsules: i) Organisms can be lumped together and formulated into a tablet. The tablet coated with a barrier film. The film protected organisms are introduced into the capsule independently. Anti-infective agent is put in the capsule containing organisms protected by a barrier film. It can be vice versa. ii) Organisnis can be granulated. Granules colOtaining organisnis iu-e coated barrier film. Barrier film coated granules are mixed with anti-infective agent before filling them into capsules.
Example II Tablets i) Layered tablets Orgtnisms are coated and compressed into a layer of tablet. The other layer(s) of tablet contains anti-infective agent. ii) Tablet containing mixture Granules of organisms are coated with barrier film and mixed with granulated material of anti-infective agents and compressed into a tablet. iii) Coated Tablets Anti-infective agents are formulated into compressed tablet. They are coated.
During coating stage organisms are introduced in the coating. Tlie coating should be capable of protecting organisms from anti-infective agents. It can be vice versa i.e. anti-infective agent is included in coating. iv) Tablet with a hole is produced containing anti-infective agent. The hole of the tablet is filled with organisms. The tablet so obtained may be coated for final finishing.
Coating/barrier protection is not so much necessary as it is in a capsule form as long as Inoisture content is controlled and physical separation is maintained in a same tablet. Formulated tablet can be dispersible tablet or simple tablet.
Example III Liquid formulations : i) The organisms are coated with barrier film mixed with other ingredients (dry form) of formulation including anti-infective agent. The product is reconstituted before use by addition of adequate amount of liquid. ii) The organisms arc coated with barrier film and suspended in a liquid containing anti-infective agents or vice versa. Tlie barrier film is stable in liquid formulation but disintegrates in body due to alteration in surrounding, e.g. pH 3. Following are examples of coating agents which can be used in making stable fixed dose pharmaceutical composition containing anti-infective agent(s) and micro organism. Ilowever, it is not intended that the scope of this invention be limited by these examples.
