Procaine penicillin Procaine penicillin is a combination of benzylpenicillin with the local anaesthetic agent procaine. This combination is aimed at reducing the pain and discomfort associated with a large intramuscular injection of penicillin.

Indications

respiratory tract infections where compliance with oral treatment is unlikely ,syphilis, cellulitis

Ciclopirox:Ciclopirox is a synthetic antifungal agent for topical dermatologic use.

Example calculations of maximum local anesthetic doses for a 15-kg child

Articaine

5 mg/kg maximum dose × 15 kg = 75 mg

4% articaine = 40 mg/mL

75 mg/(40 mg/mL) = 1.88 mL

1 cartridge = 1.8 mL

Therefore, 1 cartridge is the maximum

Lidocaine

7 mg/kg × 15 kg = 105 mg

2% lidocaine = 20 mg/mL

105 mg/(20 mg/mL) = 5.25 mL

1 cartridge = 1.8 mL

Therefore, 2.9 cartridges is the maximum

Mepivacaine

6.6 mg/kg × 15 kg = 99 mg

3% mepivacaine = 30 mg/mL

99 mg/(30 mg/mL) = 3.3 mL

1 cartridge = 1.8 mL

Therefore, 1.8 cartridges is the maximum.

Prilocaine

8 mg/kg × 15 kg = 120 mg

4% prilocaine = 40 mg/mL

120 mg/(40 mg/mL) = 3 mL

1 cartridge = 1.8 mL

Therefore, 1.67 cartridges is the maximum

Phenobarbital (Luminal): for generalized tonic-clonic and partial seizures (not used for absence seizures)

Mechanism: enhances GABA inhibition (↑ open time of Cl channels in presence of GABA)

Side effects: sedation, ataxia, cognitive impairment, induction of hepatic microsomal enzymes

PHARYNGEAL DEMULCENTS 
Administered in the form of lozenges, cough drops and cough linctus. 
Produce soothing action on throat directly and by increasing the flow of saliva and provide symptomatic relief from dry cough.

EXPECTORANT

Expectorants are the drugs which increase the production of bronchial secretion and reduce its viscosity to facilitate its removal by coughing. 

ANTITUSSIVES

They are central cough suppressants and act centrally to raise the threshold of cough centre and inhibit the cough reflex by suppressing the coordinating cough centre in the medulla oblongata. 

Codeine - it depresses cough centre but is less constipating and abuse liability is low.

Pholcodeine is similar to codeine in efficacy and is longer acting. It has no analgesic or addicting property.

Noscapine is another opium alkaloid of benzylisoquinoline group. It is used as antitussive with no analgesic and drug abuse or drug dependence property. 

Dextromethorphan is a synthetic compound and its dextroisomer is used as antitussive and is as effective as codeine

Pipazethate is another synthetic compound of phenothiazine category used as antitussive with little analgesic and sedative properties.

ANTIHISTAMINICS
They do not act on cough centre but provide relief due to their sedative and anticholinergic action.

BRONCHODILATORS
Bronchodilators are helpful in individuals with cough and bronchoconstriction due to bronchial hyperreactivity. They help by improving the effectiveness of cough in clearing secretions.
