Q1. According to the Indian Pharmacopoeia (IP), what is the mandatory recommended storage temperature range defined for “Cold” storage condition?
- (A) Between 2°C and 8°C
- (B) Between 8°C and 25°C
- (C) Below 0°C
- (D) Exactly at -20°C
Detailed Solution: Under the Indian Pharmacopoeia general notices:
- Cold: Any temperature between 2°C and 8°C (e.g., Insulin, Vaccines, Sera, Erythropoietin).
- Cool: Any temperature between 8°C and 25°C.
- Room Temperature: The temperature prevailing in a working area (usually 20°C to 30°C).
- Warm: Any temperature between 30°C and 40°C.
- Excessive Heat: Any temperature above 40°C.
Q2. In hospital inventory control, the ‘VED’ analysis technique classifies pharmaceutical stock based on:
- (A) Annual monetary consumption value
- (B) Criticality and clinical importance of drugs to patient survival
- (C) Rate of shelf-life movement and expiration
- (D) Procurement lead time from central medical stores
Detailed Solution: VED analysis categorizes hospital medicines into:
- V (Vital): Life-saving drugs whose absence cannot be tolerated even for a few minutes (e.g., Adrenaline, Atropine, Oxygen). Must have 100% availability.
- E (Essential): Drugs without which hospital functioning will suffer, causing serious inconvenience (e.g., Antibiotics, Analgesics).
- D (Desirable): Medicines for minor ailments, absence does not impair medical treatment (e.g., Multivitamin syrups).
In contrast, ABC analysis is based on annual monetary expenditure, while FSN analysis is based on rate of inventory consumption.
Q3. Which of the following anti-tubercular agents is notorious for causing dose-dependent Retrobulbar Optic Neuritis leading to loss of visual acuity and red-green color blindness?
- (A) Isoniazid
- (B) Rifampicin
- (C) Ethambutol
- (D) Pyrazinamide
Detailed Solution: Ethambutol causes optic neuritis resulting in decreased visual acuity, central scotoma, and early impairment of red-green color discrimination. It is contraindicated in children under 6 years of age because visual acuity cannot be reliably monitored. Isoniazid causes peripheral neuropathy (prevented by Pyridoxine / Vitamin B6), Rifampicin causes orange-red discoloration of body secretions, and Pyrazinamide causes hyperuricemia and arthralgia.
Q4. Under Schedule H1 of the Drugs and Cosmetics Rules, what is the mandatory retention period for the dedicated register containing records of Schedule H1 drug sales?
- (A) 1 Year
- (B) 2 Years
- (C) 3 Years
- (D) 5 Years
Detailed Solution: Schedule H1 was introduced under the Drugs and Cosmetics Rules in August 2013 to curb the misuse of third- and fourth-generation antibiotics, anti-TB drugs, and habit-forming psychoactive substances (contains 46 drugs). The registered pharmacist must maintain a separate register recording the patient’s name, doctor’s name, drug name, and quantity dispensed. This register must be preserved for a minimum period of 3 years and made available for inspection by Drug Inspectors.
Q5. What is the active metabolite of Spironolactone responsible for its extended potassium-sparing diuretic action?
- (A) Canrenone
- (B) Amiloride
- (C) Triamterene
- (D) Eplerenone
Detailed Solution: Spironolactone undergoes extensive first-pass hepatic metabolism into its principal active metabolite, Canrenone (and 7alpha-thiomethylspironolactone). While spironolactone itself has a short plasma half-life of ~1.5 hours, Canrenone has an elimination half-life of 16 to 18 hours, providing prolonged competitive antagonism of aldosterone receptors in the late distal tubule and collecting ducts.
Q6. Which law states that “The rate of dissolution of a solid drug particles is directly proportional to the concentration gradient and surface area of the drug”?
- (A) Fick’s First Law of Diffusion
- (B) Noyes-Whitney Equation
- (C) Henderson-Hasselbalch Equation
- (D) Stokes’ Law
Detailed Solution: The Noyes-Whitney equation (dC/dt = DA/h * (Cs – C)) governs the dissolution rate of solid dosage forms, where D is diffusion coefficient, A is surface area, h is stagnant diffusion layer thickness, Cs is saturation solubility, and C is concentration in the bulk dissolution medium. Stokes’ law governs the sedimentation rate of suspensions. Henderson-Hasselbalch calculates pH and ionization of weak acids/bases.
Q7. Why must sublingual Nitroglycerin (Glyceryl Trinitrate) tablets be dispensed strictly in original amber glass containers with tight-fitting metal screw caps?
- (A) To prevent photolytic oxidation of the nitrate ester
- (B) Nitroglycerin has high vapor pressure and undergoes rapid volatilization and sorption into plastic
- (C) To prevent hygroscopic moisture absorption and tablet swelling
- (D) To avoid chemical polymerization into dinitro-derivatives
Detailed Solution: Nitroglycerin is a highly volatile aliphatic ester with significant vapor pressure. It rapidly evaporates or adsorbs/absorbs into conventional plastic containers and pill boxes, resulting in substantial loss of potency. Patients must be counseled never to store NTG with cotton plugs or transfer tablets into plastic dispensers, and to discard unsealed bottles after 3 to 6 months.
Q8. Under the Drugs & Cosmetics Rules 1945, which statutory cautionary statement must be printed in a box with a red border on the label of Schedule G drugs?
- (A) ‘To be sold by retail on the prescription of a Registered Medical Practitioner only’
- (B) ‘Caution: It is dangerous to take this preparation except under medical supervision’
- (C) ‘Warning: To be sold by retail only on the prescription of a Registered Medical Practitioner’
- (D) ‘Narcotic & Psychotropic Drug — Lock & Key Storage Required’
Detailed Solution: Schedule G drugs (mostly hormonal substances and antineoplastics like Metformin, Glibenclamide, Hydroxyurea, Testosterone) require the specific warning: “Caution: It is dangerous to take this preparation except under medical supervision”. In contrast, Schedule H and H1 carry the standard prescription warning with the red ‘Rx’ or ‘Rx in red box’.
Q9. Co-administration of broad-spectrum oral antibiotics with Warfarin significantly elevates the patient’s prothrombin time (INR) and bleeding risk because:
- (A) Antibiotics displace Warfarin from plasma albumin binding sites
- (B) Antibiotics eradicate intestinal gut flora responsible for synthesizing Vitamin K2
- (C) Antibiotics directly induce hepatic cytochrome CYP2C9 enzymes
- (D) Antibiotics enhance gastrointestinal absorption of Warfarin tablets
Detailed Solution: Intestinal commensal bacteria synthesize menaquinones (Vitamin K2), which provide up to 50% of the body’s daily vitamin K requirement necessary for gamma-carboxylation of clotting factors II, VII, IX, and X. Broad-spectrum antibiotics (e.g., Cephalosporins, Fluoroquinolones, Tetracyclines) eradicate gut flora, precipitating acute Vitamin K deficiency and markedly potentiating Warfarin’s anticoagulant effect, leading to elevated INR and severe hemorrhage.
Q10. Which of the following specific chelating agents is indicated for acute Iron poisoning in pediatric emergency admissions?
- (A) D-Penicillamine
- (B) Deferoxamine (Desferrioxamine)
- (C) Dimercaprol (BAL)
- (D) Calcium Disodium EDTA
Detailed Solution: Deferoxamine has an exceptionally high and selective affinity for ferric iron (Fe3+). It binds free circulating iron and iron from ferritin/hemosiderin to form a stable, water-soluble, nontoxic chelate called Feroxamine, which is excreted renally, imparting a characteristic vin-rosé (reddish) color to urine. D-Penicillamine is used for Copper (Wilson’s disease), BAL for Arsenic/Mercury, and EDTA for Lead.
Q11. In prescription interpretation, the Latin abbreviation ‘p.c.’ translates to:
- (A) Ante cibos (Before meals)
- (B) Post cibos (After meals)
- (C) Pro re nata (As needed / when required)
- (D) Post coitum (After intercourse)
Detailed Solution: p.c. stands for Post cibos meaning “After meals” (often prescribed for gastric irritants like NSAIDs). a.c. stands for Ante cibos (“Before meals”, e.g., PPIs like Pantoprazole). p.r.n. means Pro re nata (“As needed”). s.o.s. means Si opus sit (“If necessary in emergency”).
Q12. What is the active alkaloid extracted from the dried roots of Rauwolfia serpentina (Sarpagandha) historically utilized for severe hypertension and psychosis?
- (A) Reserpine
- (B) Atropine
- (C) Strychnine
- (D) Colchicine
Detailed Solution: Reserpine is an indole alkaloid isolated from the roots of Rauwolfia serpentina (family Apocynaceae). It irreversibly blocks the vesicular monoamine transporter (VMAT-2), preventing the storage of biogenic amines (Dopamine, Norepinephrine, Serotonin) into presynaptic synaptic vesicles. Depletion of central and peripheral catecholamines lowers peripheral vascular resistance and produces tranquilizing effects, but causes severe clinical depression and peptic ulceration as major adverse reactions.
Q13. In immunization cold chain logistics, which vaccine is extremely heat-sensitive and must be stored at sub-zero temperatures (-20°C) in deep freezers?
- (A) Tetanus Toxoid (TT)
- (B) Hepatitis B Vaccine
- (C) Oral Polio Vaccine (OPV)
- (D) DPT Vaccine
Detailed Solution: Oral Polio Vaccine (OPV / Sabin live attenuated) is the most heat-sensitive childhood vaccine and must be stored at -20°C in deep freezers at district stores and state vaccine depots. Conversely, freeze-sensitive vaccines (Tetanus Toxoid, DPT, Hepatitis B) must never be frozen, as freezing irrevocably damages the aluminum hydroxide adjuvant, causing denaturation and loss of immunogenicity. Freeze-sensitive vaccines are stored strictly at +2°C to +8°C.
Q14. The classical clinical triad diagnostic of acute Morphine / Opioid poisoning consists of:
- (A) Hypertension, Tachycardia, and Mydriasis
- (B) Pinpoint Pupils (Miosis), Respiratory Depression, and Coma
- (C) Hyperthermia, Diaphoresis, and Hyperreflexia
- (D) Tremors, Rigidity, and Akathisia
Detailed Solution: The classic diagnostic triad of opioid toxicity is: (1) Coma / marked CNS depression; (2) Severe respiratory depression (often <4–6 breaths/min); and (3) Pinpoint pupils (extreme bilateral miosis) resulting from stimulation of the Edinger-Westphal nucleus of the oculomotor nerve. Intravenous Naloxone (0.4 to 2 mg IV) is the specific pure competitive opioid antagonist indicated for immediate resuscitation.
Q15. Under the Drugs and Cosmetics Rules 1945, Schedule N prescribes the statutory standards and minimum equipment for:
- (A) Life period of antibiotics and vitamins
- (B) List of minimum equipment and apparatus for the efficient running of a Pharmacy (Retail Shop)
- (C) Good Laboratory Practices (GLP)
- (D) Packaging and labeling requirements of homoeopathic drugs
Detailed Solution: Schedule N details the mandatory equipment required for opening and maintaining a licensed dispensing pharmacy, including: dispensing balance (sensitivity 10 mg), metric weights, mortars and pestles (glass and porcelain), measuring cylinders, spatulas, ointment slab, refrigerator, distilled water supply, and statutory books (Indian Pharmacopoeia, National Formulary of India, Drugs and Cosmetics Act).
Q16. What is the standard fixed-dose ratio of Trimethoprim to Sulfamethoxazole formulated in Co-trimoxazole tablets?
- (A) 1 : 1
- (B) 1 : 5
- (C) 1 : 10
- (D) 1 : 20
Detailed Solution: Co-trimoxazole tablets contain Trimethoprim and Sulfamethoxazole in a 1 : 5 ratio (e.g., Single strength = 80 mg Trimethoprim + 400 mg Sulfamethoxazole; Double strength = 160 mg Trimethoprim + 800 mg Sulfamethoxazole). Because Trimethoprim has a larger volume of distribution than Sulfamethoxazole, this 1:5 formulated ratio achieves an optimal steady-state plasma concentration ratio of 1 : 20, which delivers maximal synergistic sequential bactericidal blockade of bacterial folate synthesis.
Q17. Which of the following is a competitive antagonist of Benzodiazepines at the GABA-A receptor complex used to reverse sedation during surgical recovery?
- (A) Naloxone
- (B) Flumazenil
- (C) Physostigmine
- (D) Atropine
Detailed Solution: Flumazenil is a synthetic imidazobenzodiazepine that acts as a pure competitive antagonist at the allosteric benzodiazepine binding site on the GABA-A receptor. It reverses CNS depression and sedation induced by benzodiazepines (Midazolam, Diazepam) and Z-drugs (Zolpidem, Zopiclone) within 1 to 2 minutes of IV administration.
Q18. Atropa belladonna, Hyoscyamus niger, and Datura stramonium belong to which botanical family?
- (A) Solanaceae
- (B) Apocynaceae
- (C) Rubiaceae
- (D) Papaveraceae
Detailed Solution: Belladonna, Henbane (Hyoscyamus), and Stramonium (Datura) all belong to the Solanaceae (nightshade) family. They are classical botanical sources of tropane alkaloids, predominantly L-hyoscyamine (which racemizes to Atropine) and Scopolamine (Hyoscine), which function as competitive antagonists at muscarinic acetylcholine receptors.
Q19. What is the standard therapeutic serum drug monitoring (TDM) reference range for Digoxin in patients with heart failure?
- (A) 0.5 to 0.9 ng/mL (up to 2.0 ng/mL in AF)
- (B) 10 to 20 mcg/mL
- (C) 50 to 100 mcg/mL
- (D) 1 to 2 mg/mL
Detailed Solution: Digoxin has a narrow therapeutic index. In congestive heart failure, optimal serum trough concentration is 0.5 to 0.9 ng/mL. Levels above 2.0 ng/mL are strongly associated with fatal arrhythmias, junctional tachycardia, visual halos (xanthopsia), nausea, and hyperkalemia. Hypokalemia markedly potentiates digitalis cardiotoxicity.
Q20. Which analytical chemical test produces a deep purple/blue complex (Ruhemann’s purple) upon reacting with alpha-amino acids?
- (A) Biuret Test
- (B) Ninhydrin Test
- (C) Millon’s Test
- (D) Xanthoproteic Test
Detailed Solution: The Ninhydrin test involves oxidative deamination and decarboxylation of alpha-amino acids by triketohydrindene hydrate (ninhydrin), forming hydrindantin, ammonia, and CO2. Hydrindantin reacts with unreduced ninhydrin and ammonia to yield the characteristic deep blue-violet chromophore known as Ruhemann’s purple (absorbance at 570 nm). Proline yields a yellow pigment.
Q21. What is the approximate total circulating blood volume in a healthy 70 kg adult human?
- (A) 2 to 3 Liters
- (B) 5 to 5.5 Liters (approx. 7–8% of body weight)
- (C) 8 to 10 Liters
- (D) 12 Liters
Detailed Solution: In a standard healthy adult weighing 70 kg, total circulating blood volume accounts for approximately 7% to 8% of total body weight, equating to 5.0 to 5.5 Liters (plasma constitutes ~55% or ~3 Liters, and formed cellular elements constitute ~45% or ~2.2 Liters).
Q22. Which specific antidote is administered intravenously to neutralize acute unfractionated Heparin overdose?
- (A) Vitamin K1 (Phytomenadione)
- (B) Protamine Sulfate
- (C) Aminocaproic acid
- (D) Idarucizumab
Detailed Solution: Protamine Sulfate is a strongly basic polycationic peptide derived from salmon sperm. It binds ionically to strongly acidic, negatively charged Heparin molecules, forming a biologically inert, stable salt complex without anticoagulant activity. Approximately 1 mg of protamine neutralizes 100 units of heparin.
Q23. Under the Drugs & Cosmetics Rules 1945, Schedule C and C1 govern:
- (A) List of non-prescription OTC products

- (C) 8th Cranial Nerve (Vestibulocochlear)
- (D) 10th Cranial Nerve (Vagus)
Detailed Solution: Aminoglycosides induce selective sensory hair cell death in the cochlea and vestibular apparatus, directly damaging the 8th Cranial Nerve (Vestibulocochlear nerve). Streptomycin and Gentamicin predominantly affect vestibular function (vertigo, loss of balance), whereas Kanamycin and Amikacin cause predominantly cochlear damage (permanent sensorineural deafness).
Q33. What is the specific life-saving antidote for acute Paracetamol (Acetaminophen) hepatotoxicity?
- (A) N-Acetylcysteine (NAC)
- (B) Atropine sulfate
- (C) Naloxone
- (D) Pralidoxime
Detailed Solution: N-Acetylcysteine (NAC) replenishes intracellular hepatic glutathione stores and acts as a direct sulfhydryl surrogate, binding and neutralizing the toxic electrophilic metabolite NAPQI (N-acetyl-p-benzoquinone imine) to prevent fatal centrilobular hepatic necrosis.
Q34. What is the standard normal physiological resting blood pressure in a healthy adult human?
- (A) 80/120 mmHg
- (B) 120/80 mmHg (Systolic ≤ 120 / Diastolic ≤ 80 mmHg)
- (C) 140/90 mmHg
- (D) 100/60 mmHg

- (A) Oral Propranolol
- (B) Sublingual Nitroglycerin (0.5 mg)
- (C) Oral Amlodipine
- (D) Atorvastatin
Detailed Solution: Sublingual Nitroglycerin (0.5 mg) dissolves under the tongue and enters systemic venous circulation within 1 to 2 minutes, bypassing hepatic first-pass metabolism. It releases nitric oxide (NO), activating guanylyl cyclase to cause profound venodilation, which reduces cardiac venous return (preload) and myocardial oxygen demand, instantly relieving angina.
Q36. Which route of drug administration provides instantaneous onset of action and 100% systemic bioavailability?
- (A) Oral route
- (B) Intramuscular route
- (C) Intravenous (IV) route
- (D) Subcutaneous route
Detailed Solution: The Intravenous (IV) route places the medication directly into the circulatory system, completely bypassing biological membrane absorption barriers and hepatic first-pass clearance. Bioavailability is defined as F = 1.0 (100%).
Q37. Which cation is the predominant electrolyte in extracellular fluid (ECF) responsible for plasma osmolality?
- (A) Potassium (K+)
- (B) Sodium (Na+)
- (C) Calcium (Ca2+)
- (D) Magnesium (Mg2+)
Detailed Solution: Sodium (Na+) is the dominant extracellular cation (normal plasma concentration: 135–145 mEq/L), responsible for maintaining extracellular fluid volume and plasma osmolality. Potassium (K+) is the dominant intracellular cation (~140–150 mEq/L inside cells).
Q38. Scurvy, characterized by spongy bleeding gums, petechiae, and impaired wound healing, is caused by nutritional deficiency of:
- (A) Vitamin A
- (B) Vitamin C (Ascorbic acid)
- (C) Vitamin D
- (D) Vitamin K
Detailed Solution: Ascorbic acid (Vitamin C) is an essential cofactor for prolyl and lysyl hydroxylase enzymes that catalyze the post-translational hydroxylation of proline and lysine residues in procollagen. In Vitamin C deficiency, unstable triple-helix collagen fibers result in fragile capillary walls, leading to Scurvy.

- (B) Hydrocortisone 100 mg IV only
- (C) Atropine 1 mg IV
- (D) Dopamine 5 mcg/kg/min
Detailed Solution: Adrenaline 1:1000 IM (0.5 mg) administered into the anterolateral thigh is the life-saving drug of choice for anaphylaxis. Its potent alpha-1, beta-1, and beta-2 stimulation reverses systemic vasodilation, restores cardiac output, and relieves bronchospasm.
Q49. Which electrolyte disorder markedly aggravates Digitalis toxicity, triggering severe cardiac arrhythmias?
- (A) Hyperkalemia
- (B) Hypokalemia
- (C) Hypernatremia
- (D) Hyponatremia alone
Detailed Solution: Hypokalemia (low serum potassium, commonly induced by furosemide or thiazides) removes competitive displacement of Digoxin at the sarcolemmal Na+/K+-ATPase pump, dramatically potentiating digitalis cardiotoxicity and precipitating fatal ventricular arrhythmias.
Q50. On the Griffin HLB (Hydrophilic-Lipophilic Balance) scale, surfactants with an HLB value between 3 and 6 function as:
- (A) Solubilizing agents
- (B) Water-in-Oil (W/O) emulsifying agents
- (C) Oil-in-Water (O/W) emulsifying agents
- (D) Detergents
Detailed Solution: Lipophilic surfactants with low HLB values of 3 to 6 (e.g., Sorbitan esters / Spans) form Water-in-Oil (W/O) emulsions. Hydrophilic surfactants with HLB 8 to 16 (e.g., Polysorbates / Tweens) form Oil-in-Water (O/W) emulsions.
Q51. Which endocrine hormone is synthesized by parathyroid chief cells to elevate serum calcium levels by stimulating osteoclastic bone resorption and renal tubular calcium reabsorption?
- (A) Calcitonin
- (B) Parathyroid Hormone (PTH)
- (C) Aldosterone
- (D) Thyroxine
Detailed Solution: Parathyroid Hormone (PTH) raises blood calcium concentration by: (1) stimulating osteoclastic bone resorption; (2) increasing distal renal tubular calcium reabsorption; and (3) stimulating renal 1-alpha-hydroxylase to convert Vitamin D into active 1,25-(OH)2-D3 (calcitriol). In contrast, thyroid Calcitonin lowers blood calcium.
Q52. Schedule H1 of the Drugs and Cosmetics Rules, introduced to restrict indiscriminate retail antibiotic dispensing, contains a statutory list of how many regulated drugs?
- (A) 24 Drugs
- (B) 46 Drugs
- (C) 54 Drugs
- (D) 100 Drugs
Detailed Solution: Schedule H1 specifies exactly 46 drugs (third- and fourth-generation cephalosporins, carbapenems, fluoroquinolones, anti-TB medications, and habit-forming psychoactive substances like Alprazolam and Zolpidem). Pharmacists must maintain a separate register preserved for 3 years.
Q53. In ABO and Rh blood transfusion genetics, which blood group is recognized as the ‘Universal Recipient’ for packed red blood cell transfusions?
- (A) O Negative (O-)
- (B) AB Positive (AB+)
- (C) A Positive (A+)
- (D) B Negative (B-)
Detailed Solution: Individuals with AB Positive (AB+) blood express A, B, and Rh(D) antigens on their red blood cells and possess no anti-A, anti-B, or anti-D antibodies in their plasma, allowing them to safely receive packed red cells of any ABO/Rh blood type (Universal Recipient). O Negative (O-) possesses no ABO or Rh antigens on erythrocytes and is the Universal Donor.
Q54. In medical prescription direction, the Latin term ‘o.d.’ (omni die) instructs the patient to take the medicine:
- (A) Twice daily
- (B) Once a day (Daily)
- (C) Every other day
- (D) Four times a day
Detailed Solution: o.d. stands for Omni die (“Once daily”). b.i.d. stands for Bis in die (“Twice daily”). t.i.d. stands for Ter in die (“Three times daily”). q.i.d. stands for Quater in die (“Four times daily”). q.o.d. stands for Quaque altera die (“Every other day”).
Q55. The principal antimuscarinic alkaloid obtained from Atropa belladonna leaves is:
- (A) Ephedrine
- (B) Atropine (racemic DL-hyoscyamine)
- (C) Strychnine
- (D) Physostigmine
Detailed Solution: Atropa belladonna (Deadly Nightshade) contains the tropane alkaloid L-hyoscyamine, which readily racemizes during extraction to form optically inactive DL-hyoscyamine (Atropine). Atropine competitively antagonizes muscarinic M1, M2, and M3 acetylcholine receptors.
Q56. What is the standard diagnostic normal reference range for Fasting Plasma Blood Glucose in a healthy non-diabetic adult?
- (A) 40 to 60 mg/dL
- (B) 70 to 100 mg/dL
- (C) 126 to 140 mg/dL
- (D) 180 to 200 mg/dL
Detailed Solution: According to WHO and ADA clinical standards:
- Normal Fasting Blood Glucose: 70 to 99 mg/dL (or <100 mg/dL).
- Impaired Fasting Glucose (Prediabetes): 100 to 125 mg/dL.
- Diabetes Mellitus: Fasting plasma glucose ≥ 126 mg/dL (or Postprandial ≥ 200 mg/dL, or HbA1c ≥ 6.5%).
Q57. As per the Indian Pharmacopoeia, Dispersible Tablets must completely disintegrate in water at 15°C–25°C within:
- (A) 3 Minutes
- (B) 10 Minutes
- (C) 15 Minutes
- (D) 30 Minutes
Detailed Solution: Dispersible Tablets are designed to produce a smooth, homogenous dispersion when placed in a small volume of water. As per the IP, they must completely disintegrate within 3 minutes and the resulting dispersion must pass through a sieve with a nominal mesh aperture of 710 μm (sieve No. 22).
Q58. Neonatal ‘Gray Baby Syndrome’ is caused by deficiency of which hepatic metabolic enzyme leading to toxic accumulation of Chloramphenicol?
- (A) Cytochrome P450 3A4
- (B) UDP-Glucuronyl Transferase
- (C) N-Acetyltransferase
- (D) Alcohol dehydrogenase
Detailed Solution: Immature hepatic UDP-Glucuronyl Transferase in premature infants and neonates fails to conjugate Chloramphenicol, causing elevated serum levels that poison myocardial and vascular electron transport, culminating in cardiovascular collapse and gray cyanosis (Gray Baby Syndrome).
Q59. Which Schedule under the Drugs and Cosmetics Rules 1945 prescribes the statutory list of minimum equipment and apparatus for the efficient running of a retail pharmacy?
- (A) Schedule M
- (B) Schedule N
- (C) Schedule O
- (D) Schedule P
Detailed Solution: Schedule N details the statutory list of minimum apparatus, balances, weights, measuring equipment, and reference books legally required to operate an open retail pharmacy. Schedule M governs GMP, Schedule O sets standards for disinfectant fluids, and Schedule P sets life periods.
Q60. The Central Council (Pharmacy Council of India – PCI) was first constituted by the Government of India in which year?
- (A) 1948
- (B) 1949
- (C) 1952
- (D) 1955
Detailed Solution: Under Section 3 of the Pharmacy Act 1948, the Central Council of Pharmacy (PCI) was officially constituted in 1949 to regulate pharmacy education, establish the Education Regulations (ER), and register qualified pharmacists across India.
